Answer:
f(x+2) = - 6x - 5
Step-by-step explanation:
As we have f(x) =- 6x + 7, then we also have f(x+2) = - 6(x+2) + 7 = - 6x - 12 + 7 = - 6x - 5.
Answer:
Step-by-step explanation:
x^2+6x+5x = x^2 + 11x = x*(x+11)
But I do not know what you are looking for? Zeroes? Then they are x=0 and x= -11
17)
x² + 8 = -8
x² = -8 - 8
x² = 16
x = ±√-16
x = ±√16i
x = <span>±4i
</span>
18)
x² + 5 = -3
x² = -3 - 5
x² = -8
x = ±√-8
x = ±√8i
x = ±2√2i
19)
x² + 3 = 0
x² = -3
x = ±√-3
x = <span>±</span>√3i
hope this helps, God bless!
The cost of an apple pie is $13 and a blackberry pie is $18.
<h3>How to find the cost?</h3>
Let A be apple pies and B be blackberry pies.
3A + 11B = $237
3A + 12B = $255.
On solving the quadratic equation, we get
-B = -18
Therefore,
B = 18
Substitute B in any one of the equations,
3A + 11*18 = 237
3A = 237 - 198
A = 39/3
A = 13
The cost of an apple pie is $13 and a blackberry pie is $18.
