Answer:
x = 8 , y = 3
Step-by-step explanation:
3x + 2y = 30
3x - y = 21 -> y = 3x - 21
3x + 2 (3x - 21) = 30
3x + 6x - 42 = 30
3x + 6x = 30 + 42
9x = 72
x = 72/9 = 8
y = 3*8 - 21 = 24 - 21 = 3
∴ x = 8 & y = 3
Answer:
-9
Step-by-step explanation:
-9 * -9 = 81
-9 + -9 = -18
Answer: -9
Answer:
0
Step-by-step explanation:
Remember that f(x) stands for y. No number can be equal to 0 other than it self. Thus, proving that 0 is only logical answer.
f(x) = 0 → y = 0 → 0 = 0
Best of Luck!
The linear function has an equation
y = -3x + 6
The equation of the circle is
<span>y2 + x2 = 16
Substituting
(-3x + 6)^2 + x^2 = 16
This quadratic equation has real solutions which mean that the line and the circle will intersect
