Answer:
Step-by-step explanation:
Since we know the slope and a point, we can use the point-slope form.
The point-slope form is:
Substitute 8 for m, and let (-4,-3) be x₁ and y₁, respectively. Thus:
Simplify:
Distribute:
Subtract 3 from both sides:
And we're done!

Answer:
y = (x-1)^2 - 2
Step-by-step explanation:
The parabola vertex point is always (h, k) in y = (x-h)^2 + k
All you have to do is look at h and k to find your vertex. Since in y = (x-1)^2 -2 has an h of -1 (Which makes it positive 1 when you plug it in) and a k of -2, that means that is your answer.
Answer:
x < 3
Step-by-step explanation:
−4x − 8 > −20
Add 8 to both sides.
-4x > -12
Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.
-4x/(-4) < -12/(-4)
x < 3
Answer:
C.) percent= 20%, Amount=unknown, Base =50
Step-by-step explanation:
The percent is the percent, so 20% is the percent.
The number you take the percent of is the base. The base is 50.
Once you calculate the percent of the base, you get the amount.
We are given the percent, 20%, the base, 50, but not the amount.
