Answer:
50mph
Step-by-step explanation:
Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.
A = 50+10
b = 50-10
A = 60
B = 40
A2 = 120
B3 = 120
120 = 120
Answer
120km
Step-by-step explanation:
let s = the original speed
Write a distance equation; dist = time * speed
3(s-10) = 2(s+10)
3s - 30 = 2s + 20
3s - 2s = 20 + 30
s = 50 km/hr is the original speed
confirm this, find the distances
3(50-10) = 120 km
2(50+10) = 120 km
Abby is painting two cubes for an art project.
Cube 1: side length = 3 feet
Cube 2: side length = 2 feet
The surface area of a cube is 6s2, where s is the length of one side.
Find the total surface area that Abby will paint.
1. Find the surface area of cube 1. Show your work, and include units with your answer.
2. Find the surface area of cube 2. Show your work, and include units with your answer.
3. What is the total area Abby will paint?
Answer:
54 sq ft, 24 sq ft, 78 sq ft
Step-by-step explanation:
1. Each side of cube 1 is 3 feet x 3 feet, so each side has an area of 9 square feet. Multiply by 6 sides and the area is 54 square feet.
2. Each side is 2 feet x 2 feet so the area of one side is 4 square feet. Multiply by 6 sides and the area is 24 square feet.
3. 54 + 24 = 78 square feet

Step-by-step explanation:
I think the answer should be C
Answer: A
(2, -4) and (0,4);
x, y x, y
A. y = -4x +4; substitute the pairs
(2,-4)
-4 = -4(2) + 4 = -4; -4 = -4
(0,4)
4 = -4(0) + 4 = 4; 4 = 4
B. y = -4x - 4
(2, -4)
-4 = -4(2) - 4 = -12; -12 ≠ -4
(0,4)
4 = -4(0) - 4 = -4; -4 ≠ 4
C. y = 4x - 4
(2, -4)
-4 = 4(2) - 4 = 4; 4 ≠ -4
(0,4)
4 = 4(0) - 4 = -4; -4 ≠ 4
D. y = 4x + 4
(2, -4)
-4 = 4(2) + 4 = 12; 12 ≠ -4
(0,4)
4 = 4(0) + 4 = 4; 4 = 4

F(x) = 6 (1/8)^x is an example of
An exponential growth function
A logarithmic growth function
An exponential decay function
A logarithmic decay function
Answer:
Exponential decay. Your growth factor is 1/8, which is between 0 and 1. Thus, the value is decreasing exponentially.
If the growth factor is greater than 1, you have exponential growth. Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.

which of the following is not an expression?
Answer:
3x + 4 = 7
Step-by-step explanation:
Equations contain an equal sign, but expressions only contain numbers and variables.
The expression in option A) is not an expression as it is a equation.
What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here, option A as 3x+4=7 thus it is an linear equation but an expression is a polynomial where there are no signs such as<,>=
Hence, Option A is the correct answer.

Enter your answer in the box.
Answer:
18 units cubed. (18units³) also, replace 'units' with whatever units you were given (cm, inches, etc.)
Step-by-step explanation:
(the answer below is assuming each cube has a length of one unit. If they have a different length, then multiply the final answer by the length squared) (answer x length x length)
answer: there are six rows of cubes with 3 cubes in each row each. Each cube is 1x1, so 6 x 3 x 1 x 1 = 18. (with units): 18units³
