I'm confused to do you have an example
Its just a matter of subbing
-7x - 4y = 6....subbing in (-2,2)...x = -2 and y = 2
-7(-2) - 4(2) = 6
14 - 8 = 6
6 = 6 (correct)
so ur solution is (-2,2)
Answer:
2x - 5 if x ≤ 2
f(-1) = -7
Step-by-step explanation:
x ≤ 2 = (-1) ≤ 2
x > 2 = (-1) > 2
2x - 5
2(-1) - 5
-2 - 5
-7
Answer:
C
Step-by-step explanation:
4 x 4=16 and half of 4 is 2 so the answer is C)4
Divide I from both sides then subtract r from both sides, too so in the end:
R= (E-r)/I
