I would say the answer is b, because it states -4 + 4 = 0
Answer:
x ≤15
Step-by-step explanation:
2x ≤30
Divide each side by 2
2x/2 ≤30/2
x ≤15
I don’t know but hope you find out!
Answer:
y = -⅓x + 3
Step-by-step explanation:
To find the equation of the graph in the form of y = mx + b (slope-intercept form), we have to find the slope (m) and the y-intercept (b) of the graph:
Slope (m) = change in y/change in x
Slope (m) using the two points on the line, (0, 3) and (3, 2):
m = (2 - 3)/(3 - 0) = -1/3
m = -⅓
y-intercept (b) = 3 (the y-axis is intercepted at this point)
✔️To write the equation, substitute m = -⅓ and b = 3 into y = mx + b:
Thus,
y = -⅓x + 3
Answer: -25
Since x=-3, y=6, and z=-4 you have to plug those numbers into the corresponding varibale in the equation. So 3x becomes 3(-3) because x=-3, 2y becomes 2(6) because y=6 and z becomes just -4. The whole equation comes to 3(-3)- 2(6)+(-4)= -25
