Answer:
4x² - 57x + 206
Step-by-step explanation:
To evaluate (t ￮ s)(x), substitute x = s(x) into t(x) , that is
t(x - 7)
= 4(x - 7)² - (x - 7) + 3 ← expand (x - 7)² using FOIL
= 4(x² - 14x + 49) - x + 7 + 3
= 4x² - 56x + 196 - x + 10 ← collect like terms )
= 4x² - 57x + 206
1) 3(3x - 4) = -2(1 – 4x)
Answer:
x = 10
Step-by-step explanation:
3(3x - 4) = -2(1 - 4x)
9x - 12 = -2 + 8x
9x - 8x = -2 + 12
x = 10

Dominick wants to determine the maximum capacity of a cylindrical bucket that has a radius of 6 inches and a
height of 12 inches. What is the capacity of Dominick's bucket? Round your answer to the nearest tenth. Don't
forget the label.
Hey there! I'm happy to help!
To find the volume of a cylinder, you multiply the base by the height.
First, let's find the base.
The base is a circle. To find the area of a circle, you square the radius and multiply by 3.14 (pi).
6²=36
36(3.14)=113.04
We multiply this by the height.
113.04(12)=1356.48
And we round to the nearest tenth.So, the maximum capacity of Dominick's bucket is 1356.5 cubic inches. If you use the entire pi number you would get something more around 1357.2, so that could be the answer if the first is incorrect.

Is there a dilation that maps shape II onto shape I? If so, what is the scale factor and is it an enlargement or a reduction?
Shape II was dilated by a scale factor of 1/3 to form shape I. This is a reduction since the scale factor is less than 1.
What is transformation?Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, rotation and dilation.
Shape II was dilated by a scale factor of 1/3 to form shape I. This is a reduction since the scale factor is less than 1.
Find out more on transformation at: https://brainly.com/question/4289712
#SPJ1
Answer: A dilation will map shape I onto shape II. The bottom left coordinate of shape I is (1, 1) and the bottom left coordinate of shape II is (3, 3). So, to get the corresponding coordinates of shape II, multiply the coordinates of shape I by 3. This is true for every set of coordinates. So, the scale factor is 3. Because the scale factor is 3, which is greater than 1, the dilation is an enlargement.

x+5y-10=2x solve for y
Answer:
x + 5y -10 = 2x
or, 5y = 2x - x + 10
or, 5y = x + 10
or, y = (x + 10)/5

What is 5x-(3+7)=9+2(x-8)
Answer:
x= 1
Step-by-step explanation:
5x - (3+7)=9+2(x-8)
Add the numbers 3 + 7= 10
5x - 10= 9 + 2(x-8)
Expand 9 + 2(x-8): 2x - 7
5x - 10 = 2x - 7
Add 10 to both sides
5x -10 + 10 = 2x -7 + 10
Simplify 5x = 2x + 3
Subtract 2x from both sides
5x -2x = 2x + 3- 2x
Simplify
3x = 3
Divide both sides by 3
3x/3 =3/3
Simplify
x= 1
