17/21 - (2/7 + 1/7)
Please solve!!
Answer:
8/21
Step-by-step explanation:
17/21 - (2/7 + 1/7)
= 17/21 - ( 3/7)
= 17/21 - (3×3/7×3)
= 17/21 - 9/21
= 8/21

There really should be no answer to this. It sort of destroys the meaning of equality. However, you might be working in different bases. I'll assume that, but the base will be a fraction, which brings up other problems.
Solution
You have 5 17s there. So you will need five 32s. 5 * 32 = 160
The answer is 160
The function y = f(x) is graphed below. What is the average rate of change of the
function f(x) on the interval -8 ≤ x ≤ 8?
The average rate of change of the function is -35/16.
How to find the average rate of change of the function?We have to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ 8.
so
at x₁ = -8, f(x₁) = f(-8) = 30
at x₂ = 8, f(x₂) = f(8) = -5
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [f(8) - f(-8) ] / [8-(-8)]
= [-5 - (30)] / [16]
= [-35] / 16
Therefore, the average rate of change of the function is -35/16.

Solve for x (12x-7)/4=(5x+18)/3
Answer:
Step-by-step explanation:do i know u
Answer:
x= 5.8125
Step-by-step explanation:
Given: [tex]\frac{12x-7}{4} =\frac{5x+18}{3}[/tex]
Since we have one fraction equal to another fraction, we can cross multiply.
(12x -7)(3)= 4(5x +18)
Expand:
36x -21= 20x +72
Bring all the x terms to one side, constant to the other:
36x -20x= 72 +21
Simplify:
16x= 93
Divide both sides by 16:
[tex]x= \frac{93}{16}[/tex]
x= 5.8125

The rotations which will map this figure itself are 60°, 120°, and 180°, and these values are given in option i.e. (a) ii, iii, and iv.
We have,
A figure which is on a straight line i.e 180°.
Now,
Find the rotations which it will make,
When a person or figure rotates completely i.e. to reach to its original position or shape it makes an angle of 360°.
So,
In the same way;
After rotaions of this figure to reach it to its original position it has to make an angle of 360°.
So,
That means,
First this figure will make a rotation of 60°.
Then it will make a rotation of 120°.
Then it will make a rotation of 180°.
i.e.
The sum of these angles = 60° + 120° + 180° = 360°.
So,
We have to choose that option, in which the sum of angles is 360°.
i.e.
Option 1. ii, iii, and iv.
Therefore, the rotations which will map this figure itself are 60°, 120°, and 180° and these values are given in option i.e. (a) ii, iii, and iv.

Step-by-step explanation:
0.3x plus 24, 5x, and 0.2x minus 15

This means that,
0.3x + 24 + 5x + 0.2x - 15
We know the perimeter of the triangle is,
P = a+b+cWhere a , b , c refers to the sides of that triangle.
So Just add them up:

What is the inverse of the function f(x) = 4x + 8?
Answer: A. h(x) = 1/4x - 2
Step-by-step explanation:
f(x) = 4x + 8
find the inverse...
A.
[tex]h(x) = \frac{1}{4} x-2[/tex]
[tex]f(x) = 4(\frac{1}{4} x-2)+8[/tex]
[tex]f(x)=x-8+8[/tex]
[tex]f(x)=x[/tex]
[tex]h(x) = \frac{1}{4} (4x+8)-2[/tex]
[tex]h(x)=x+2-2[/tex]
[tex]h(x)=x[/tex]
Since they both come out to 'x', they are inverses of each other.
f(x) = 4x + 8 and h(x) = 1/4x - 2 are inverses

How to Find the Actual Area Using Scale?
Given that the area of the house on a blueprint = is 7 square inches.
The scale of the blueprint = is 1 inch: 6 feet.
Therefore, we would have the following proportion:
The area on the blueprint/actual area = square of the scale
7/actual area = 1²/6²
7/actual area = 1/36
Actual area = (7)(36)
Actual area = 252 square feet.
