Answer: It would be -8.
Step-by-step explanation: -4 = x so -4 squared is -16 times 1/2 which is -8.
Answer:
42
Step-by-step explanation:
Answer:
The last option.
Step-by-step explanation:
Looking at the equations and their y-intercepts is enough information to know that the last graph is the only answer that could be correct
#A
Two similar triangles are GCE and BPE
#B
- GP similar to BP
- GB similar to BE
- Angle B is same in both
By using SAS Property triangles are similar.
#C
Ans: multiply by -2
A: 2x + 8y = 5
B: x + 9y = 10
B x (-2) : -2x - 18y = -20
A + B:
8y - 18y = 5 - 20
- 10y = -15
y = 1.5
To solve for x
B: x + 9y = 10
x + 9(1.5) = 10
x + 13.5 = 10
x = 10 - 13.5
x = -3.5
