The x-intercept of a function is basically it's roots. So when you factor out the function f(x) = x^2 - 16x + 64 you get
(x-8)(x-8)
x = 8
So x-int. is (0,8) or x = 8
Answer:
(-4, -1)
Step-by-step explanation:
-3x - 8y = 20; y = 5x + 19
y = 5x + 19; -3x - 8y = 20
y = 5x + 19
-3x - 8y = 20
-3x - 8(5x + 19) = 20
-43x - 152 = 20
-43x - 152 + 152 = 20 + 152
-43x = 172
-43x / -43 = 172 / -43
x = -4
y = 5x + 19
y = (5)(-4) + 19
y = -1

Step-by-step explanation:
Step-by-step explanation:
2x-y=4 means y=2x-4. -> slope of the parallel line is 2.
so using pt slope form,
y+11=2(x+3)
y+11=2x+6
y=2x-5
