Answer:
Step-by-step explanation:
Given that:
x + 4y = 30
x - 2y = 0
Subtracting both equations:
6y = 30
y = 30/6
y = 5
Putting in above equation
x + 4(5) = 30
x + 20 = 30
x = 10

Answer:
f(-2) = -4x + 6
Step-by-step explanation:
f(x) = 2x + 6
f(-2) = -2(2x) + 6
f(-2) = -4x + 6
Answer:
6
Step-by-step explanation:
Answer:
<em>64 ; 8</em>
Step-by-step explanation:
a² ± 2ab + b² = (a ± b)²
x² + 2(8)(x) + 8² =
x² + 16x + <em>64</em> =
(x + <em>8</em>)²
You can use substitution or elimination or graphing to solve the equation. Since both of the equations are in slope intercept form it will be easier to use substitution or to graph it and find the point of interception.
