X^2+7x+49/4=-11+49/4
(X+7/2)^2=5/4
X=-9/4
"A number used to multiply a variable.
Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.
Variables with no number have a coefficient of 1.
Example: x is really 1x.
<span>Sometimes a letter stands in for the number. </span>
Example: In ax2<span> + bx + c, "x" is a variable, and "a" and "b" are coefficients."
hope this helps you!

Answer:
the slope of the line passing through the points (-4,-4) and (2, 5) m=3/2.
Step-by-step explanation:
Hello!
To find the slope between two points use the formula
- m=(y₂-y₁)/(x₂-x₁)... substitute values
- m=(5-(-4))/(2-(-4))
- m=9/6
- m=3/2
