Y = x + 4
y = -2x - 2
x + 4 = -2x - 2
x + 2x = -2 - 4
3x = -6
x = -6/3
x = -2
y = x + 4
y = -2 + 4
y = 2
solution is (-2,2)
Answer:
23
Step-by-step explanation:
You can simply substitute -2 into the x of the equation.
f(-2) = (-2)^4 + 2(-2)^2 -1
= 23
Here's the equation:
<u>4x</u> = <u>10
</u><u />4 4 You would have to divide 4 on both sides to get isolate variable.
x = 2.5
Five multiplied by two times three multiplied by 15
