You find the rate of changes on graphs by the x values
Split to in ten parts each part is 4 minus one (cause it’s only nine out of ten) means 40 minus one part (4) so the answer is 36
Answer:
B. -8
Step-by-step explanation:
x-3y=136
18x+3y=-288
add the equations
19x=-152
divide by 19
x=-8
Answer:
15
Step-by-step explanation:
1) multiply numerator x numerator and denominator x denominator
- 24/12
2) simplify the fraction
-24 : 12 = -2
12 : 12 = 1
-2/1 = -2
3) inverte the therms of -2/15 and change the sign of operation from : to x
- 2 x (-15/2)
4) multiply the numerators remembering that minus x minus = +
30/2
5) simplify the fraction
30 : 2 = 15
2:2 = 1
15/1 = 15
You need numbers to find that out
