Answer:
(-2, 1).
Step-by-step explanation:
The x coordinates are -1 and -3 and the y coordinates are 4 and -2.
So the midpoint is (-1 + -3)/2, ( 4 + -2) / 2
= (-4/2, 2/2)
= (-2, 1).
Answer:

Step-by-step explanation:
Vertex form of a quadratic equation;

Vertex of the parabolas (h, k)
The vertex of the parabola is either the minimum or maximum of the parabola. The axis of symmetry goes through the x-coordinate of the vertex, hence h = -3. The minimum of the parabola is the y-coordinate of the vertex, so k= 7. Now substitute it into the formula;

Now substitute in the given point; ( -1, 9) and solve for a;

Hence the equation in vertex form is;

In standard form it is;

Answer:
B
Step-by-step explanation:
According to the given situation,
If X, then Y indicates y depends on X
If Y, then Z indicates Z depends on Y
As per the given situation, Y is true also Z will be true on the other hand there no solution about x b as y depends on X
Therefore as per the above explanation, the correct answer is B and hence the same is to be considered

Answer:
Darlene bought more fabric
Darlene bought 3.4 yards more
Step-by-step explanation:
Darlene = 7 yards + 20% extra
= 7 yards + (20% of 7 yards)
= 7 + (20% × 7)
= 7 + (0.2 × 7)
= 7 + 1.4
= 8.4 yards
Chris = 4 yards + 25% of 4 yards
= 4 yards + (25% of 4 yards)
= 4 + (25% × 4)
= 4 + (0.25 × 4)
= 4 + 1
= 5 yards
Darlene bought more fabric
How much more?
Darlene - Chris
= 8.4 yards - 5 yards
= 3.4 yards
Darlene bought 3.4 yards more
