Answer:
9 is your answer.
Step-by-step explanation:
Solve for b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 9 to both sides:
8b - 9 (+9) = b (+9)
8b = b + 9
Next, subtract b from both sides:
8b (-b) = b (-b) + 9
8b - b = 9
7b = 9
Divide 7 from both sides:
(7b)/7 = (9)/7
b = 9/7
Plug in 9/7 for b in the equation given:
7(b) = 7(9/7) = 9
9 is your answer.

UwU
Yes, the conveyors are in a proportional relationship.
Given,
A conveyor belt moves at a constant rate of 12 feet in 3 seconds.
A second conveyor belt moves 16 feet in 4 seconds.
We need to find whether the two conveyors are in proportion relationship.
What is a proportional relationship?
There is a proportional relationship if the ratios of each pair of values are the same.
We have,
- First conveyor belt
12 feet in 3 seconds.
Ratio = 12 / 3 = 4
- Second conveyor belt
16 feet in 4 seconds.
Ratio = 16 / 4 = 4
Ratios are the same.
4 = 4
Thus the conveyors are in a proportional relationship.

What is the distance between each pair of points?
Answer:
The square root of 145.
Step-by-step explanation:
For this problem, make a right triangle between these two points. To solve for distance, use the Pythagorean formula. We know that one side is 8, and the other side is 9, so square 8 and 9 to get 64 plus 81. When you add these together, you get the square root of 145. You cannot further simplify the square root of 145, so that is the distance between the pair of points.
Answer:
For any two points there is exactly one line segment connecting them. The distance between two points is the length of the line segment connecting them. Note that the distance between two points is always positive. Segments that have equal length are called congruent segments.

BC = 4
BC = 18
BC = 7
BC = 12
answer is BC=4
notice that the starting point is A and the endpoint is C, it stated that from A to B the value is 7 and from A to C the value is 11 we just need to subtract AC-AB to find the third value of it
AC-AB= 11-7 =4

A rectangle has sides that measure 2 x + 11 units long and 10 x + 1 units long. What is the expression that represents the perimeter of the rectangle?
Answer:
(24x + 24) units
Step-by-step explanation:
A rectangle is a shape that has four sides in which all angles are equal and opposite sides are equal and parallel to each other. The perimeter of a rectangle is the sum of all its sides. Since opposite sides are equal, the perimeter is given as:
Perimeter = 2(length + width)
Since the sides of the rectangle are 2 x + 11 units long and 10 x + 1 units long. Hence:
Perimeter = 2(2x + 11 + 10x + 1)
Perimeter = 2(2x + 10x + 11 + 1) = 2(12x + 12)
Perimeter = (24x + 24) units

A faucet leaks 4 oz. of water per minute. How many gallons of water are wasted in a year? (128 oz. = 1 gallon)
Answer: 16,425 gallons are wasted a year
Step-by-step explanation:
First find out how many minutes there are in a year then multiply it by how much oz the faucet leaks every years then convert it into gallons.
There are 525,600 minutes in a year now multiply it by 4.
525,600 * 4 = 2,102,400 So there are more than 2 million oz wasted in a year so now convert it to gallons.
If there are 128 oz for every gallons the divide 2,102,400 by 128 to find out how many gallons are wasted a year.
2,102,400 / 128 = 16,425

3(4x-7)=27 i don't know what to do
Answer:
x = 4
Step-by-step explanation:
Given
3(4x - 7) = 27 ( divide both sides by 3 )
4x - 7 = 9 ( add 7 to both sides )
4x = 16 ( divide both sides by 4 )
x = 4
Answer:
x=4
Step-by-step explanation:
Distribute the 3 to the 4x and -7v
it will be 12x - 21= 27
you then take the 21 and add it to the 27 to isolate the 12x
it will be 12x = 48
to seperate the 12 from the x you divide on both sides so x/12 and 48/ 12
this will give you x= 4

IF YOU COULD HELP ME I'D BE SO GRATEFUL! (Giving out brainliest) The points A(0,5), B(4,2), and C(0,2) form the vertices of a right triangle in the coordinate plane. What is the equation of the line that forms the hypotenuse?
Step-by-step explanation:
The line that forms the hypotenuse includes line AB.
Gradient of line AB = Rise/Run = (5-2)/(0-4) = -3/4.
y = -3/4 * (x) + c
When x = 0, y = 5. Hence c is 5.
The equation is y = 5 - (3x/4).
A submarine dives below the surface, heading downward in two moves. If each move downward was 355 feet, where is the submarine after it is finished diving?
Answer: The submarine would be 710 feet below the surface after it is finished diving.
Step-by-step explanation:
Given: Each move downward was of 355 feet
If the submarine dives below the surface, heading downward in two moves.
Then, the total distance moved by submarine = 2 (355) feet
= 710 feet
Therefore, the submarine would be 710 feet below the surface after it is finished diving.

The graph of a function g is a
transformation of the graph of

f(x). Write a rule for g
Answer:
[tex]g(x)=5.4x+3[/tex], graph of f(x) vertically compressed by factor 0.6 to get g(x).
Step-by-step explanation:
The given function is
[tex]f(x)=9x+5[/tex]
It is given that the graph of a function g is a transformation of the graph of
f (x), where g(x) is 60% of f(x). So, we need to write a rule for g.
[tex]g(x)=60\%\text{ of }f(x)[/tex]
It means graph of f(x) vertically compressed by factor 0.6 to get g(x).
[tex]g(x)=\dfrac{60}{100}(9x+5)[/tex]
[tex]g(x)=0.6(9x+5)[/tex]
[tex]g(x)=0.6(9x)+0.6(5)[/tex]
[tex]g(x)=5.4x+3[/tex]
Therefore, [tex]g(x)=5.4x+3[/tex]. Graph of f(x) vertically compressed by factor 0.6 to get g(x).

Answer:
The function is missing in the question. The function is [tex]$ C(x) = 0.8x^2 -544x +97410 $[/tex]
The answer is 4930
Step-by-step explanation:
Unit cost of a car is given as
[tex]$ C(x) = 0.8x^2 -544x +97410 $[/tex]
Cost will be minimum when
x = -(-544)/ 2 x 0.8
= 340
Therefore, minimum cost for unit car is
[tex]$ C(x) = 0.8x^2 -544x +97410 $[/tex]
[tex]$ = 0.8(340)^2 -544(340) +97410 $[/tex]
= 4930
