Answer:
$5
Step-by-step explanation:
32-27 = 5
because he was earning 27 per skate board, that function shows him earning 32 per skate board which is an increase of $5.
Answer:
Step-by-step explanation:
x-4=0
x=4
i solve by synthetic division.
4| 1 -7 14 -8
| 4 -12 8
___________
| 1 -3 2 | 0
![x^3-7x^2+14x-8=(x-4)(x2-3x+2)\\=(x-4)[x^2-x-2x+2]\\=(x-4)[x(x-1)-2(x-1)]\\=(x-4)(x-1)(x-2)](https://tex.z-dn.net/?f=x%5E3-7x%5E2%2B14x-8%3D%28x-4%29%28x2-3x%2B2%29%5C%5C%3D%28x-4%29%5Bx%5E2-x-2x%2B2%5D%5C%5C%3D%28x-4%29%5Bx%28x-1%29-2%28x-1%29%5D%5C%5C%3D%28x-4%29%28x-1%29%28x-2%29)
x-intercepts are (4,0),(1,0),(2,0)
put x=0
y=-8
y -intercept is (0,-8)
The answer to this problem is D. 2^4x=2^3x-9
Answer:
3x−1
Step-by-step explanation:
1 Split the second term in 6{x}^{2}+x-16x
2
+x−1 into two terms.
\frac{6{x}^{2}+3x-2x-1}{4{x}^{2}-1}
4x
2
−1
6x
2
+3x−2x−1
2 Factor out common terms in the first two terms, then in the last two terms.
\frac{3x(2x+1)-(2x+1)}{4{x}^{2}-1}
4x
2
−1
3x(2x+1)−(2x+1)
3 Factor out the common term 2x+12x+1.
\frac{(2x+1)(3x-1)}{4{x}^{2}-1}
4x
2
−1
(2x+1)(3x−1)
4 Rewrite 4{x}^{2}-14x
2
−1 in the form {a}^{2}-{b}^{2}a
2
−b
2
, where a=2xa=2x and b=1b=1.
\frac{(2x+1)(3x-1)}{{(2x)}^{2}-{1}^{2}}
(2x)
2
−1
2
(2x+1)(3x−1)
5 Use Difference of Squares: {a}^{2}-{b}^{2}=(a+b)(a-b)a
2
−b
2
=(a+b)(a−b).
\frac{(2x+1)(3x-1)}{(2x+1)(2x-1)}
(2x+1)(2x−1)
(2x+1)(3x−1)
6 Cancel 2x+12x+1.
\frac{3x-1}{2x-1}
2x−1
3x−1
