Answer:
5
Step-by-step explanation:
First figure out the equation:
We know this is a linear equation because it appears to have a constant slope
Its y-intercept is where it passes in the y-axis, so it's -8
Furthermore, you should also figure out the slope. Notice that the y value increments by 3 every 1 x-value. Rise/Run is 3/1 = 3. Thus, the slope is 3
So your equation is g(x) = 3x - 8
Now we find our inverse function, which is just swapping the x-y values.
Thus, inverse of g(x) ==> y = 3x - 8 ==> x = 3y - 8 ==> x+8 = 3y ==> 
Plug in 7 for x and you get 5
Answer:
x = 48 ft
Step-by-step explanation:
Triangle DEF is similar to triangle XYZ
10 x 4 = 40 ft
so
12 x 4 = 48 ft
Answer
x = 48 ft

Answer:
2.20
Step-by-step explanation:
The GPA is the weighted average of the grade points. The weights are the number of course hours.
((16 hours)(3.0) +(7 hours)(1.0) +(21 hours)(2.0))/((16 +7 +21) hours)
= 97/44 ≈2.20 . . . . GPA
Answer:
There are no solutions.
Step-by-step explanation:
4x+5=6x+18-20-2x (Distributive Property)
4x+2x-6x=18-20+5 (Combine Like Terms)
0=3 (Simplify)
That doesn't make any sense, so there are no solutions.
