Answer:
a>-8
Step-by-step explanation:
-4
2/3a>-12
a>-8
<span>Thus, the standardized form of a quadratic equation is ax2 + bx + c = 0, where "a" does not ... We said that the graph of y = x2 was a function because it passed the vertical line test. .... Find the vertex of the parabola y = 2x2 - 12x + 7. ... To find the y-value, we would substitute 3 in for x, or find f(3) = 2(3) 2 — 12(3) + 7 = -11.</span>
First, we need to use the distributive property to simplify the expression. So, that means we have to multiply the 4 by all of the integers and variables inside the parentheses.
If done correctly, your expression should be 6+12x-8+5
Next, we should combine all of the constant terms (just numbers without variables), also known as combining like terms.
If done correctly, your expression should be 12x+3.
This matches answer B. 12x+3
Answer: D
Step-by-step explanation:
Sum of adjacent angles on a straight line is 180°
x+56°=180°...
x=180°-56°
x=124°
