How do you evaluate and interpret algebraic expressions? To evaluate an algebraic expression, substitute the value(s) of the (select) into the expression and simplify using the order of operations. To interpret an algebraic expression, identify the (select) of each (select) .
Answer:
see explanation
Step-by-step explanation:
When you have an algebraic expression and you are required to evaluate the algebraic expression, all you need to do is to substitute the give values of each variable into the expression.
For instance, if you intend to evaluate 2x + 2 where x=2, all you need to do is to substitute 2 or x. That is 2(2) + 2=4
However, to interpret an algebraic expression, all you need to do is to identify all the terms and variables in the expression.
Solve for x. 1+|2+x|=9
Answer:
x= −10,6
Step-by-step explanation:
Subtract 1 from both sides.
|2+x|=9-1
Simplify 9−1 to 8.
∣2+x∣=8
Break down the problem into these 2 equations.
2+x=8
-(2+x)=8
Solve the 1st equation: 2+x=8

The height in feet, h, of a model rocket t seconds after launch is given by the equation h (t) = 3 + 70 t minus 16 t squared. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the model equation:
h (t) = 3 + 70t - 16t²
h = height in feet
t = time in seconds
Average rate of change in h(t) between
t= 1 second and t = 3 second
At t = 1 second
h(1) = 3 + 70(1) - 16(1)^2 = 57
At t = 3 second
h(3) = 3 + 70(3) - 16(3)^2 = 69
Average rate of change = Δh / Δt
Δh / ΔT = [h(3) - h(1)] / (3 - 1)
= (69 - 57) / 2
= 12 / 2
= 6
Hence, it is the mean or average change in height h as time, t changes

Step-by-step explanation:
what does m equal?
m/5 + 5 = 7
m =
Answer:
10
Step-by-step explanation:
First step is to get rid of the 5 on the left side of the equation. To do this, subtract 5 from both sides like this:
m/5 + 5 - 5 = 7 - 5
The 5s on the left side add to zero so you're left with m/5 + 0.
The right side now is 7 - 5 or 2.
So m/5 = 2. Now multiply both sides by 5 to get rid of the denominator 5 on the left side.
5 x m/5 = 2 x 5
On the left, 5 divided by 5 is 1 so you now have just m.
On the right you have 2 x 5 or 10
So m = 10

f(x) =10x+4
f(x)=15/2 x-20
f(x)=10x-4
f(x)=2/15x-20
Answer:
the answer is option b. f(x)=15/2 x -20
Step-by-step explanation:
i took the test and used that answer and got it right
The equation f(x) = (15/2)x - 20 represents the line depicted on the graph.
Option B is the correct answer.
What is a function?A function has an input and an output.
The inputs are called the domain of the function.
The output is called the range of the function.
We have,
From the graph, we see that
x = represents the years.
y = represents the profits.
At x = 0 years,
y = profits = -20 millions
At x = 4 years,
y = profits = 10 millions
The function:
f(x) = (15/2)x - 20
f(0) = 15/2 x 0 - 20 = 0 - 20 = -20
f(4) = 15/2 x 4 - 20 = 30 - 20 = 10
Thus,
The equation f(x) = (15/2)x - 20 represents the line depicted on the graph.
Option B is the correct answer.

Step-by-step explanation:
You work in a packaging store. A customer brings in a basketball to be put in a box. The available box is 25
centimeters (cm) on all sides, and the ball has a diameter of 9.55 inches.
Will the ball fit inside the box?
O The ball will fit, because its diameter is approximately 12 cm.
O The ball will fit, because its diameter is approximately 14 cm.
O The ball will fit, because its diameter is approximately 1 cm shorter than the side of the box.
O The ball will not fit, because its diameter is approximately 3 cm longer than the side of the box.
The ball will not fit, because its diameter is approximately 14 cm longer than the side of the box.
Given:
Length of each side of the box = 25 cm
Diameter of the ball = 9.55 inches.
To find:
Whether the ball will fit inside the box.
Solution:
The ball will fit inside the box if the diameter of the ball is less than or equal to length of each side of the box.
Length of each side of the box = 25 cm
We know that, 1 inch = 2.54 cm
Diameter of the ball = 9.55 inches.
= (9.55 × 2.54) cm
= 24.257 cm
Clearly, 24.257 cm < 25 cm. Diameter is approximately 1 cm shorter than the side of the box.
Therefore, the ball will fit, because its diameter is approximately 1 cm shorter than the side of the box.
Hence, the correct option is C.
