6.6 is value t in of linear equation .
What is linear equation with example?
Ax+By=C represents a two-variable linear equation in its standard form. A standard form linear equation is, for instance, 2x+3y=5. Finding both intercepts of an equation in this format is rather simple (x and y).A linear equation with one variable has the conventional form Ax + B = 0. x is a variable, A is a coefficient, and B is constant in this situation.2t + 3/3 = 3t - 8/2
2( 2t + 3 ) = 3( 3t - 8 )
4t + 6 = 9t - 24
9t - 4t = 9 + 24
5t = 33
t = 33/5
t = 6.6

A shipping container will be used to transport several 150-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 26500 kilograms. Other shipments weighing 12100 kilograms have already been loaded into the container. Which inequality can be used to determine x, the greatest number of 150-kilogram crates that can be loaded onto the shipping container?
Answers
SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the given values
[tex]\begin{gathered} \text{constant + Variable = Output} \\ \text{constant}=12100 \\ \text{Variable}=x \\ \text{Output}=\text{greatest value} \end{gathered}[/tex]STEP 2: Get the inequality
[tex]\begin{gathered} \text{ If }26500kg\text{ is the greatest value, this means that;} \\ \text{the addition of constant and variable must be less than or equal to 26500} \\ So\text{ we have;} \\ \\ 150x+12100\le26500 \end{gathered}[/tex]Hence, the answer is:

Answers
Given that the height of a tree increases as time passes.
Your friend says that is dependent because size deemds on time.
Leet's determine if your friend is correct.
Here, since the height of a tree increases as time passes, the height of the tree depends on the time.
Hence, size is the dependent variable while time is the independent variable.
Therefore, your friend is NOT correct.

A ship leaves port on a bearing of 34.0 degrees and travels 10.4 mi. The ship then turns due east and travels 3.9 mi. How far is the ship from port, and what is its bearing from port?
Answers

, at a bearing angle of
50.4

Explanation:
We're asked to find the total displacement, both the magnitude and direction, of the ship after it leaves the port with the given conditions.
First, I'll explain what a bearing is.
A bearing is NOT a regular angle measure; normally, angles are measured anticlockwise from the positive
x
-axis, but bearing angles are measured clockwise from the positive
y
-axis.
Therefore, a bearing of
34.0
o
indicates that this is an angle
90.0
o
−
34.0
o
=
56.0
o
measured normally. We'll use this angle in our calculations.
We're given that the first displacement is
10.4
mi
at an angle of
56.0
o
(as calculated earlier). Let's split this up into its components:
x

o
=
5.82
m
y

=

=

Our second displacement is a simple

due east, that is, the positive
x
-direction. The components are thus

=

To find the total displacement from the port, we'll add these two vectors' components and use the distance formula:

The average rate of change of the function from x = 4 to x = 7 is: -1/3.
How to Estimate the Average Rate of Change of a Function?The formula used to estimate the average rate of change of a function is given as:
f(b) - f(a) / b - a.
Given the function as shown in the diagram below, we are required to find the average rate of change of the function within the interval, x = 4 to x = 7, therefore:
a = 4
b = 7
f(a) = f(4) = 4
f(b) = f(7) = 3
To find the average rate of change of the given function for the interval of x = 4 to 7, substitute the above stated values into the formula for the average rate of change, f(b) - f(a) / b - a:
Average rate of change = 3 - 4 / 7 - 4

Answers
B the purchase cost of the aquarium
Explanation
we have the equation
[tex]y=48x+250[/tex]this is a linear equation in the form
[tex]\begin{gathered} y=\text{ mx+b} \\ \text{where m is the slope and b is the y-intercept} \end{gathered}[/tex]hence
[tex]\begin{gathered} y=48x+250\rightarrow y=mx+b \\ \text{slope}=48 \\ y-\text{intercept}=250 \end{gathered}[/tex]so, if we have the sentence
the cost in dollars, y, of purchasing and maintaining a classroom aquarium for x months
let
cost in dollars = y
as x is the variable, let x for the variable in the text, in this case, what changes is the number of months,so
number of months= x
the factor of x ( 48), is the value for the mainting the classroom ( as we can see it depends on the number of months , x)
so
the monthly cost of the aquarium=48
finally , we have 250, this values is a constant, it does not depend on the number of months, so it is
the purchase cost of the aquarium=250
so,the answer is
B the purchase cost of the aquarium

Q.12 The polynomials are 2 and 3
What is polynomial ?
A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables. An example of a polynomial of a single indeterminate x is x² − 4x + 7.
Given, p(x) = -x² + x + 2
p has a degree 2
Let, a = 1 + i√2
b = 1 - i√2
a + b = 1 + i√2 + 1 - i√2
= 2
a * b = (1 + i√2) * (1 - i√2 )
= 1 - (i√2)²
= 1 - i²*2 (where, i² = -1)
= 1 + 2
= 3
Therefore, the polynomial are 2 and 3

Luther made $9,000 in interest by placing $60,000 in a savings account with simple interest for 3 years. What was the interest rate?
Answers
Answer:
[tex]5\%\text{ or }0.05[/tex]
Step-by-step explanation:
Simple interest rate means if I have "P" amount that I initially deposited, then every year this amount increases by "x% of P" or the original amount I deposited. So it's increasing by the same amount each year, unlike compound interest.
The formula for calculating the amount of interest is: [tex]I=P*r*t[/tex]
Where, r is the interest rate, t is the time unit, and P is the initial amount.
In most cases the t will be expressed in years, and one thing to note is the r is the interest rate in decimal form, so [tex]30\%=0.30[/tex], we want to convert it to decimal form by dividing by 100
We know the amount of interest, as it's given to us as 9,000, and the principle amount or initial amount, given to us as 60,000, and also the time which is given to us as 3 years.
So we know that:
[tex]I=9,000\\P=60,000\\t=3\\[/tex]
Plugging all these values into the equation we get:
[tex]9,000=60,000*3*r\\\\9,000=180,000*r\\\\\frac{9,000}{180,000}=r\\\\0.05=r[/tex]
as noted above, this interest rate, "r" is expressed in decimal form. Since we have to divide by 100 to convert from percentage to decimal, we have to multiply by 100 to convert from decimal to percentage.
this gives us: [tex]r=5\%[/tex]
A rectangle has a length that is 7 less than 4 times the width. The perimeter is 100 in. Find the length and the width.
Answers
Answer:
136 m
Step-by-step explanation:
Let w = the width of the rectangular field.
Let l = the length of the rectangular field.
The formula for the perimeter P of the rectangular field is:
P = 2w + 2l
Since the length l is 7 m less than 4 times the width w, then we can write the following equation that relates l and w:
l = 4w - 7 m
Since l = 4w - 7 and it's given that perimeter P = 136 m, then we can substitute this information into the perimeter formula as follows:
P = 2w + 2l
136 m = 2w + 2(4w - 7 m)
136 m = 2w + 2(4w) - 2(7 m)
136 m = 2w + 8w - 14 m
136 m + 14m = 10w - 14 m + 14 m
150 m = 10w + 0
10w = 150 m
(10w)/10 = 150 m/10
(10/10)w = 150 m/10
(1)w = 15 m
w = 15 m
Therefore, l = 4w - 7 m
l = 4(15 m) - 7 m
l = 60 m - 7m
l = 53 m
CHECK:
P = 2w + 2l
136 m = 2(15 m) + 2(53 m)
136 m = 30 m + 106 m
136 m = 136 m

Any rotating figure will twist. Although it is the same size and shape as before, the figure appears to have toppled over. A clock is a perfect example of how rotation works in real life. A clock's connecting arms turn around its axis every hour or every day. A rotation's degree determines what kind of rotation it is; typical rotations include 90, 180, and 270 degrees. Before turning around and going back to where it started, the figure does a full 360-degree turn. the direction of a rotation, whether it be clockwise or counterclockwise.
