Step-by-step explanation:
x = -6.5
these angles are congruent so
5x-7=7x+6
Answer:
11. -42
12. 9
13. 100 + (-100) = 0
14. 6 + (-4) = 2
Step-by-step explanation:
11. -42 + 36 would be the same as 42 - 36 but in this case it's negative, so that would be -6.---- -6 + (-36) equals -36 minus 6, or -42 (a negative plus a negative is always a negative)
12. -17 + 17 = 0 , 0 + 9 = 9
13. since the hawk started at 100 ft, add (-100) to get 0 (ground level)
14. leah ran 6 blocks north, then 4 blocks south, so add 6 + (-4)

-Hope this helped
if you legit just meant f(3)
that would be
3f

Answer:
Dell made $16.38
Step-by-step explanation:
This is a linear equation y = mx+b, where m is the slope and b, the y-intercept.
Since we know this graph passes through A(1,4) and B(5,6), we can find easily the equation:
1st- Calculate m = (y₂-y₁)/(x₂-x₁) → m = (6-4)/5-1) = 2/4 →m =1/2
Now y = (1/2) + b.
2nd. To calculate b, replace x and y by either the coordinate of A(1,4) or B(5,6)
Let's take A where x = 1 and y = 4 for instance:
y =(1/2)x + b
4=(1/2)(1) + b
4=1/2 + b
4-1/2 = b and b= 7/2
Finally te equation becomes: y = (1/2)x + 7/2
