Answer:

f=16/7.3x

Step-by-step explanation:

Lets solve for f:

f(7.3)=16

Step 1:Divide both sides by 7.3x

7.3f/7.3x=16/17.3x

f=16/7.3x

(8x-5) (2x) (3x-10). what is the largest angle??
kompoz [17]
8x-5 would be the largest angle because as you approach a larger and larger x value, 8x-5 will skyrocket past the other two. Also when you plug in a low value like 1, 8x-5=3, which is still higher than the other two. The only exception is if you plug in a negative x value which is impossible.
8x-5

PLEASE HELP PLA
aleksley [76]

Answer:

y = -x+8

Step-by-step explanation:

The side that is parallel to BC is EF

Find the slope of EF:

m = \frac{2-4}{6-4} =\frac{-2}{-2} =-1

Easiest way is just put the formula in point-slope form and simplify.

Let's use point F, which is (6,2)

y -2=-(x-6)

Simplify:

y-2=-x+6

Add 2 on both sides:

y = -x+8

Hope this helped
