Slope intercept form: y = mx + b
m = slope
b = y-intercept.
We have m which is -2
y = -2x + b
We need to find the y-intercept so plug 6 for x and 7 for y (6,7)
7 = -2 * 6 + b
7 = -12 + b
19 = b
Now put b in the equation
y = -2x + 19
Answer:
3x^2-2+2x^2-6x+3=5x^2-6x+1
Factor: 5x^2-5x-x+1=5x(x-1)-1(x-1)=5x-1(x-1)
Step-by-step explanation:
If you have answer choices, the answer would be 5x2 − 6x + 1.

Answer:
x ≈ 7.00
y ≈ 12.21
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships ...
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
__
Translated to the figure at hand, these are ...
cos(35°) = 10/y ⇒ y = 10/cos(35°) ≈ 12.21
tan(35°) = x/10 ⇒ x = 10·tan(35°) ≈ 7.00
Answer:
1. Simplify: (4x2 - 2x) - (-5x2 - 8x).
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Step-by-step explanation:
"Vertical integration helped the Carnegie Steel business because it reduced costs along the supply chain from mining and transportation to manufacturing. Carnegie bought out coal fields, iron mines and railroad lines to ensure that he could control the raw materials and transportation lines."
