Answer:
sorry I didn't have my phone on me, look at the photo it's the answer btw
Step-by-step explanation:
-q/-7≥-1
q/7≥-1
q≥-1*7
q≥-7
Solution: q≥-7 or q∈[-7,+∞).
In this question, you're solving for y:
Solve for y:
-3(4y - 7) - y = -2(y - 2)
<em>use the distributive property:</em>
-12y + 21 - y = -2y + 4
<em>combine like terms:</em>
-13y + 21 = -2y + 4
<em>add 2 to both sides</em>
-11y + 21 = 4
<em>subtract 21 from both sides</em>
-11y = -17
<em>divide both sides by -11</em>
y = 17/11
You would check your answer by plugging in 17/11 to the y variables.
Vertex: V=(-2,-3)=(h,k)→h=-2, k=-3
The parabola is horizontal, then its equation has the form:
x=a(y-k)^2+h
x=a(y-(-3))^2+(-2)
x=a(y+3)^2-2
When the y-value is -2, the x-value is -5:
-5=a(-2+3)^2-2
-5=a(1)^2-2
-5=a(1)-2
-5=a-2
-5+2=a-2+2
-3=a
a=-3
Answer: The coefficient of the squared term in the parabola's equation is a=-3
Answer: Option D. -3
