Two negatives is a positive so the equation is Z+3/4=13/2
-3/4
Z=26/4-3/4
Z=23/4
Find the unit rate
do 2597÷21
Answer: 124 strikeouts per year
First, make it an improper fraction, 7x4 is 28. 28+1 is 29. So the improper fraction is 29/7. Then, divide 29 by 7. The answer is 4.14 rounded to the tenths place.
Y = -2x - 4
x + 4y = 19
x + 4(-2x - 4) = 19
x + (-8x) - 16 = 19
-7x - 16 = 19
-7x = 35
-x = 5
x = -5
y = -2x - 4
y = -2(-5) - 4
y = 10 -4
y = 6
Solution set {-5, 6} (C)
7. is C 3/50
8. is H 2/3
9. is C 2/3
10. is B slope 4 y intercept -2
11. is -1/4 slope
12. is 1/5 slope
13. is -2/3 slope
14. is 6 is the slope
15. is y=5/3x+5
16. is y=1/2x-3
17. is y=-3/5x+4
18. is y=3/2x-3 :)
