What is the slope of the line represented by 9x - 14y = 28?
Answer:
The slope of the line is [tex]\displaystyle \frac{9}{14}[/tex].
Step-by-step explanation:
We are given the line in standard form:
[tex]9x - 14y = 28[/tex]
We need to get this into slope-intercept form in order to determine the slope of the line.
Slope-intercept form is [tex]y = mx + b[/tex], where m is our slope and b is the y-intercept.
Therefore, we need to get:
[tex]9x - 14y = 28[/tex]converted to:
[tex]y = mx +b[/tex].[tex]\displaystyle 9x - 14y = 28\\\\-14y = -9x + 28\\\\\frac{-14y}{-14}=\frac{-9x+28}{-14}\\\\y = \frac{9}{14}x-2[/tex]
Therefore, by solving the equation in slope-intercept form, we see that m equals 9/14, so our slope is [tex]\displaystyle \frac{9}{14}[/tex].
What’s the solution of x+y=29 and y=4x-11
Answer:
x = 8
y = 21
Step-by-step explanation:
y = 4x − 11
x + y = 29
Solve for x:
x + y = 29
x + 4x − 11 = 29
5x − 11 = 29
5x = 40
x = 8
Solve for y:
y = 4x − 11
y = 4 × 8 − 11
y = 21
The foundation of the house is 13 m x 7 m if the builder increases each dimension by the same amount the area of the foundation will increase to 135 m² find the new dimensions
Answer:
New dimension:
Length = 15m
Width = 9m
Step-by-step explanation:
Length = 13m
Width = 7m
Area of a rectangle = length × width
New dimensions:
Length = (13 + x)m
Width = (7 + x)m
Where,
x = increase in each dimension
Area of a rectangle = length × width
(13 + x) × (7 + x) = 135
91 + 13x + 7x + x² = 135
91 + 20x + x² = 135
x² + 20x = 135 - 91
x² + 20x = 44
x² + 20x - 44 =0
Using factorization method to solve quadratic equation
x² - 2x + 22x - 44 = 0
x(x -2) + 22(x - 2) = 0
(x - 2) (x + 22) = 0
x = 2 , x = -22
The increase can not be a negative value
Therefore, the increase in the dimensions is 2 inches
New dimensions:
Length = (13 + x)m
= (13+2)m
= 15m
Width = (7 + x)m
= (7+2)m
= 9m

Answer:
i) exponential; values have a common ratio; f(x) = -2·4^x
ii) linear; values have a common difference; f(x) = 4x -3
iii) exponential; values have a common ratio; f(x) = 4·2^x
Step-by-step explanation:
Sequential, or evenly-spaced, input values will result in output values with a common difference if the function is linear. They will result in output values with a common ratio of the function is exponential.
The initial value, or y-intercept, is the value when x=0. The general form of the formulas is ...
linear: f(x) = (common difference)·x + (initial value)
exponential: f(x) = (initial value)·(common ratio)^x
__
i) The f(x) values have a common ratio of -8/-2 = 4, so the relation is exponential. The initial value is f(0) = -2. The equation is ...
f(x) = -2·4^x
__
ii) The f(x) values have a common difference of 1 -(-3) = 4, so the relation is linear. The initial value is f(0) = -3. The equation is ...
f(x) = 4x -3
__
iii) The f(x) values have a common ratio of 8/4 = 2, so the relation is exponential. The initial value is f(0) = 4. The equation is ...

The amount a hardware store pays for buying nylon rope is represented by the equation y 5 0.12x, where y is the price it pays for x feet of rope. The amount the hardware store charges when selling the rope is represented by the graph.
The profit the store makes on the rope can be found by subtracting the amount it charges for the rope from the price it pays for the rope. If the store sells 80 feet of rope, how much profit does it make on that rope?
(Look at the link)

Answer:
Ayo its ( $6.40 )
Step-by-step explanation:
I did it for my do now once.
The profit would be $6.4 if the store sells 80 feet of rope the answer would be $6.4.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The amount a hardware store pays for buying nylon rope is represented by the equation
y = 0.12x, where y is the price it pays for x feet of rope.
Plug x = 80 feet
y = 0.12(80)
y = $9.6
The equation for the graph:
y = 0.20x
Plug x = 80 feet
y = $16
The profit = 16 - 9.6 = $6.4
Thus, the profit would be $6.4 if the store sells 80 feet of rope the answer would be $6.4.

Eloise bought 3 boxes of crackers to share with her friends over the weekend. They ate 1/2 box of crackers on Saturday and 2/3 box of crackers on Sunday.
How many boxes of crackers were left over?
1 3/5 boxes
1 5/6 boxes
2 3/5 boxes
2 5/6 boxes
Answer:
C.) 1 5/b boxes
Number of boxes left over
= 3 - 1/2 - 2/3
Convert each fraction to one in terms of the LCM:
= 18/6 - 3/6 - 4/6
= 11/6
= 1 5/6 boxes.
The solution is Option B.
The number of boxes of crackers left with Eloise is 1 5/6 boxes of crackers
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of boxes of crackers left with Eloise be = A
Now , the total number of boxes of crackers be = 3 boxes
The number of boxes of crackers ate on Saturday = 1/2
The number of boxes of crackers ate on Sunday = 2/3
So , the equation will be
Number of boxes of crackers left with Eloise A = total number of boxes of crackers - number of boxes of crackers ate on Saturday - number of boxes of crackers ate on Sunday
Substituting the values in the equation , we get
Number of boxes of crackers left with Eloise A = 3 - 1/2 - 1/3
On simplifying the equation , we get
Number of boxes of crackers left with Eloise A = 5/2 - 2/3
Number of boxes of crackers left with Eloise A = ( 15 - 4 ) / 6
Number of boxes of crackers left with Eloise A = 11/6
Number of boxes of crackers left with Eloise A = 1 5/6 boxes
Therefore , the value of A is 1 5/6 boxes
Hence , the number of boxes left is 1 5/6 boxes of crackers

What type of angles are these?
Answer:
I believe that the answer is the 5th one (Adjacent angles).
Step-by-step explanation:
Adjacent angles are two angles that share a common side and vertex.
Complementary angles are mostly the same but their degrees add up to 90.
Supplementary angles are similar to complementary angles but add up to 180 degrees.
Vertical angles intersect though each other and are not perpendicular (which perpendicular angles also intersect, but all angles are 90 degrees and they all add up to 360 degrees).
Linear angles are like their name, they are linear. And, they usually intersect like vertical angles. Have a linear relationship between the angles.
The angles shown on the pictures are not any of the answers, except adjacent. They don't add up to 90 degrees, so they are not complementary. They share the same common side and vertex. These facts lead up to one answer which is adjacent. These angles are adjacent.
Hope this explanation helps! :)

Answer: x = -6
Step-by-step explanation:
Since 2 angles have to equal 180, you add both of the angles you see and figure out what that answer is
101+91=192
192 - x - x
192 - 6 - 6 = 180
Answer: x=-6
Step-by-step explanation:
They are supplementary angles so both measures = 180. So x+91+x+101=180. 2x+192=180. 2x=-12. X=-6
x + y = 8
x - y = 2

Answer:
40 + 4√13
Step-by-step explanation:
A kite is a quadrilateral (has four sides) with two pairs of equal adjacent sides. The longer diagonal of a kite bisects the shorter diagonal.
Since in kite JKLM, diagonal KM bisects JL, hence KM is the longer diagonal.
JP = LP
JL = 12
JL = JP + LP
12 = JP + LP
2JP = 12 (LP = JP)
JP = 6
We can find JK using Pythagoras theorem, hence:
JK² = JP² + KP²
JK² = 4² + 6²
JK² = 16 + 36
JK² = 52
JK = √52 = 2√13
JK = KL = 2√13
ML = JM = 20
Perimeter of kite = JK + KL + ML + JM = 20 + 20 + 2√13 + 2√13
Perimeter of kite = 40 + 4√13

A model car is 12 inches
long. Using a scale of
3inches : 4 feet, how long
is the actual car?
A. 1 foot
B. 9 feet
C. 16 feet
Answer: C
Step-by-step explanation: If a car is 12 inches a room could possibly be 16 feet and a room and a car might or if not might have the same width
I hoped i helped :)
Answer: C) 16 feet
=======================================================
Work Shown:
3 inches on paper = 4 feet in real life
Multiply both sides by 4 so that the "3 inches on paper" turns into "12 inches on paper"
We get
4*(3 inches on paper) = 4*(4 feet in real life)
12 inches inches on paper = 16 feet in real life
This leads to the answer C) 16 feet.
--------------------------
Alternative Method:
(3 in on paper)/(4 ft in real life) = (12 in on paper)/(x ft in real life)
3/4 = 12/x
3*x = 4*12 ... cross multiply
3x = 48
x = 48/3 .... dividing both sides by 16
x = 16
The car's length is 16 feet in real life.
