X=brick y=sticks
x=2y
4x+4y=771
4(2y)+4y=771
8y+4y=771
12y=771
y= 771/12
y = 64.25
x = 64.25*2=128.5
Answer:
128.5+64.25*3=321.25kg
The invese switches x and y so basically
if
f(21)=z then f⁻¹(z)=21
therefor
f(z)=21 and f⁻¹(21)=z
basically solve for the value that makes the functino equal 21
21=6(x+2)-3
add 3 both sides
24=6(x+2)
divide by 6
4=x+2
minus 2
2=x
answer is 2
Multiply the diameter by PI which is 3.14 so that means the circumference would be 15.7.
Answers:
- Enlargement
- The new larger rectangle is 16.8 inches by 8.4 inches
==============================================================
Explanation:
I'm assuming 7/5 is the scale factor. If so, notice how 7/5 = 1.4 which is larger than 1.
The scale factor being larger than 1 means we have an enlargement.
The image is going to be larger compared to the preimage.
The preimage rectangle is 12 in by 6 in. Multiply each dimension by 1.4 to get 12*1.4 = 16.8 and 6*1.4 = 8.4
The image rectangle is 16.8 inches by 8.4 inches
