It's 21.125 hope this works good luck ;)
9x-5, I guess, not sure, but I'm combining like terms. Hope it's right.
Answer:
49
Step-by-step explanation:
When you look at the square of a binomial, you see ...
(x +a)^2 = x^2 +(2a)x +a^2
The constant value (a^2) is <em>the square of half the x-coefficient</em>.
(14/2)^2 = 49 . . . . the value to be added.
Adding 49 gives ...
x^2 +14x +49 = (x +7)^2
Answer:
1. A, C, and D are on the line.
1st graph:
1. The slope is 2/3.
2. The y-intercept is (0, -1)
3. The equation is y = 2/3x - 1
2nd graph:
1. The slope is 4.
2. The y-intercept is (0, -3)
3. The equation is y = 4x - 3
