Answer:
Step-by-step explanation:
3(2x + 7) - 2 (x + 5)
need to distibute
5x+10-2x+3
combine like terms
3x+13
divide
x=4.3
Combine the like terms by adding the coefficients,
->5x^4 can't add anything so leave it there,
->-3x^3 can add -3x^3 which gives you -6x^3,
->We can't do anything with -11x^2 so leave it there as well,
->6x add to -(-8x) gives you 14x,
You will get for your final answer is 5x^4-6x^3-11x^2+14x.
Answer:
C) y = 2|x - 3| - 1
Step-by-step explanation:
Point slope form: y = a(x - h) + k
The slope (a) is 2
The vertex (h, k) is (3, -1)
plug these values into the equation:
y = 2|x - 3| - 1
A) 20+10h
You know that you have 20 inches to start with, then it will grow 2h four times, or 8h total. Then it will grow h 2 times, or 2h. You add the 20, 8h, and 2h, to get 20+10h.
Hope this helps!
Answer:
(4,0)
Step-by-step explanation:
It is a linear function so you find the slope by doing y2-y1/x2-x1 and you find the slope to be 1/2. You can then setup an equation using it and graph it to find the next value.
