Answer:
y = (3/5)x+26/5 or 5y = 3x+26
Step-by-step explanation:
Applying,
The equation of a line in two point form
(y₂-y₁)/(x₂-x₁) = (y-y₁)/(x-x₁)............... Equation 1
From the question,
Given: y₂ = 7, y₁ = 4, x₂ = 3, x₁ = -2
Substitute these values into equation 1
(7-4)/[3-(-2)] = (y-4)/(x+2)
3/5 = (y-4)/(x+2)
5(y-4) = 3(x+2)
5y-20 = 3x+6
5y = 3x+6+20
5y = 3x+26
y = (3/5)x+26/5
Hence the equation of the line is y = (3/5)x+26/5 or 5y = 3x+26
Tell whether the triangle with the given side lengths is a right triangle. Y/N question
Answer:
No.
Step-by-step explanation:
33^2 + 56^2 is not equal to 66^2. I squared these numbers because that is how I can find out and see if the Pythagorean Theorem (a^2 + b^2 = c^2) is true for this.
Answer:
no , it is not a right triangle.
Step-by-step explanation:
according to the pythagoras theorem to be the right angled triangle the sum of square of two smaller sides of triangle must be equal to the square of it's hypotenuse.
Here , 66 is largest side so it is hypotenuse and other two sides are the legs of the triangle.
pythagoras theorem:
a^2 + b^2 = c^2
33^2 + 56^2 = 66^2
1089 + 3136 = 4356
4225 = 4356
since both sides are not equal it can be concluded that the given side lengths does not form right triangle.
sofia uses 8 gallons of gas to drive 204 miles. at the same rate, How many miles can sofia drive using 18 gallons of gas?
Answer:
Sophia can drive 3672 miles using 18 galloons of gas.
Step-by-step explanation:
204 x 18 = 3672.
Calculate miles per gallon by dividing the miles she drove you the gallons used:
204/8 = 25.5 miles per gallon.
Now multiply miles per gallon by gallons:
25.5 x 18 = 459 miles
Answer: 459 miles

Step-by-step explanation:
The perimeter of a rectangle is 84 cm. If the length is 29 cm write an equation you can use to answer this question
Answer:
The perimeter of a rectangle has the general formula P=2L+2W. Since you know P and L, you can plug those values into the formula and solve for W.
Hope this answer is right!!
Answer:
Width: 13
Area: 42
Step-by-step explanation:
A rectangle has equal opposite sides, so if you know one side, you know that the opposite side will be the same. Then you can subtract it from the perimeter, and divide the remaining number in half because it represents the other opposite sides. If you were trying to find the area, do that to find the length and width. 29x13=42, so the area is 42. If you were trying to find the width, that would be 13 because
29+29=58
84-58=26
And 26/2=13

Rewrite this equation in Slope Intercept form and
solve the equation at x = -1. Show your work.
2x + y = 6
Answer:
y = -2x+6
y=8 when x = -1
Step-by-step explanation:
2x + y = 6
Slope intercept form is y = mx+b where m is the slope and y is the intercept
Solve for y
Subtract 2x from each side
y = -2x+6
The slope is -2 and the y intercept is -6
Let x = -1
y = -2(-1) +6
y = 2+6
y=8
(-1,8)
Answer:
y = -2x + 6
y = 8
Step-by-step explanation:
Rewrite this equation in Slope Intercept form
2x + y = 6
Subtract 2x from both sides
y = -2x + 6
------------------------------
solve the equation at x = -1
y = -2(-1) + 6
y = 2 + 6
y = 8

Find two integers whose sum is 5 and product is -66 TWO INTEGRES
NOT 1 TWO
Answer:
-6 and 11
Step-by-step explanation:
The only factors of 66 are 11, 6, 2 and 3
11*6 is the only pair whose product is 66
The difference betwen 11 and 6 is 5
11 must be positive and 6 negative since the sum is positve

5) If (x - 5) is a factor of 2r3 - 7px + (p - 12),
find the value of p.
{ANS: p = 7)
Answer:
the value of p is 7
Step-by-step explanation:
Given function;
f(x) = 2x³ - 7px + (p - 12)
factor of the given function = x - 5
Apply remainder theorem to solve for p
f(x - 5) = 0
x - 5 = 0
x = 5
f(5) = 2(5)³ - 7p(5) + (p - 12) = 0
2(125) - 35p + p - 12 = 0
250 - 34p - 12 = 0
238 - 34p = 0
34p = 238
p = 238/34
p = 7
Therefore, the value of p is 7

Find the surface area and volume of each cylinder:
a) Radius = 5 cm, height = 7.5 cm.
b) Diameter = 7 inches, height = 5 inches, state your answer in terms of .
Cylinder A -
Surface Area:
A = 2πrh + 2πr^2
A = 2 · π · 5 · 7.5 + 2 · π · 25 ≈ 392.69908
A = 392.7 cm^2
Volume:
V = πr^2h
V = π · 25 · 7.5 ≈ 589.04862
V = 589 cm^3
Cylinder B -
Surface Area:
A = 2πrh + 2πr^2
A = 2 · π · 3.5 · 5 + 2 · π · 12.25 ≈ 186.92476
A = 186.9 cm^2
Volume:
V = πr^2h
V = π · 12.25 · 5 ≈ 192.42255
V = 192.4 cm^3
Answer:
a) surface area: 125pi volume: 187.5pi
b) (i dont know what you mean by "in terms of ." so ill give both)
surface area: 210pi or 659.734 volume: 61.25pi or 192.422
Step-by-step explanation:
a) surface area is this
2pirh+2pir^2
plug it in..
2pi(5)(7.5)+2pi(5)^2
simplify...
75pi+50pi
125pi
volume is this
pir^2h
plug it in...
pi(5)^2(7.5)
simplify...
187.5pi
b is basically same steps.

what is 5/20 as a percent if you could give an explanation that would be good but if not thats okay
Answer:25%
Step-by-step explanation:A pectange has to be out of 100 so that means 5/20 is 25/100 because 20 times 5 equals 100 and 5 times 5 equals 25 making it 25%.
Find the value of A
Answer:
a = 5
Step-by-step explanation:
Angles A and B are the same at 45, a and b are also the same
The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.
sin(A)/a = sin(B)/b = sin(C)/c
Substitute the known values into the law of sines to find a.
SinA / a = sin(90) / 5√2
a = 5

D w
+ W + 18

(ОВ
Answer:
B. 2w^2 + 2w + 36
Step-by-step explanation:
The equation to find the perimeter of anything is: Length + Length + Width + Width = Perimeter.
Applying this logic to this problem, the equation would be as follows:
[tex]w^{2} + 13 + w^{2} + 13 + w+5+w+5[/tex]
Then, we simplify. The like terms go together, and you have your solution.
[tex]2w^{2} + 2w+36[/tex]
change 45' into seconds.
Answer:
2700 seconds
Step-by-step explanation:
The notation " ' " is said as "minutes".
° = degrees; ' = minutes; " = seconds
45 minutes
1 minute = 60 seconds
1*45=60*45
45 minutes = 2700 seconds
