Step-by-step explanation:
If x + 7 is a factor of f(x), then f(-7) = 0.
f(-7) = (-7)³ − 3(-7)² + 2(-7) − 8
f(-7) = -343 − 147 − 14 − 8
f(-7) = -512
x + 7 is not a factor of f(x).
Answer:
2.5
Step-by-step explanation:
By Pythagoras theorem,
Hypotenuse = √( 4^2 + 3^2 )
= √( 16 + 9 )
= √25
Hypotenuse = 5
4 / 2 = 5 / x
2 = 5 / x
x = 5 / 2
x = 2.5
The graph<span> is shifted down k k units. Vertical Shift: Down 3 3 Units. The sign of a a</span>describes<span> the reflection across the </span>x<span>-axis. −a - a means the </span>graph<span> is reflected across the </span>x<span>-axis. Reflection about the </span>x<span>-axis: None. The value of a a </span>describes<span> the vertical stretch or compression of the</span>graph. a>1<span> a > </span><span>1</span>
Answer:
5 shifts
Step-by-step explanation:
18,000 per shift times five shifts= 90,000
Answer:
6a
Step-by-step explanation:
The GCF (Greatest Common Factor) is a number/variable that you can take out of all of the terms in the expression.
In this case, each term in this expression has a 6, and an a, but not all have an x, so we only take out:
6a
By taking 6a, you get:
6a(
+ x + 1)
