Answer:
x = - 3, y = ± 4
Step-by-step explanation:
Add corresponding elements and equate to corresponding element on right side, that is
x + 4 - 9x = 28
- 8x + 4 = 28 ( subtract 4 from both sides )
- 8x = 24 ( divide both sides by - 8 )
x = - 3
----------------------------------------------------
y² + 1 - 17 = 0
y² - 16 = 0 ( add 16 to both sides )
y² = 16 ( take the square root of both sides )
y = ± = ± 4
Answer:
3
Step-by-step explanation:
Y intercept when x = 0
F(0) = 3 * 4^(0) = 3 * 1 = 3
Answer: D
Step by step explanation:
If A to C is 3x+7 then you can plug in the numbers. B to c is 5x-5 so 5x-5-2x+ 12 gives you the total of 3x+7
