Answer:
First option
Step-by-step explanation:
In this case we must write a quadratic equation in the vertex form.
We have the vertice. (7, 9)
We know that the vertex form for a quadratic equation is:
.
Where (h, k) is the vertex.
So if the vertex is (7, 9), the equation sought is:
Therefore the answer is the first option.
The area of the frame not covered by the painting is 192 square inches
<em><u>Solution:</u></em>
Given that, A rectangular painting is 24 inches wide and 20 inches tall without the frame
The area of rectangle is given as:
<em><u>Find the area of painting without frame:</u></em>
Length = 20 inches
Width = 24 inches
Thus area of painting without frame is 480 square inches
With the frame, it is 28 inches wide and 24 inches tall
<em><u>Find the area of painting with frame:</u></em>
Length = 24 inches
Width = 28 inches
Thus area of painting with frame is 672 square inches
<em><u>What is the area of the frame not covered by the painting</u></em>
Area of the frame not covered by the painting = Area with farme - Area without frame
Area of the frame not covered by the painting = 672 - 480 = 192
Thus the area of the frame not covered by the painting is 192 square inches

4 out of 5 games is 80%:
So if we know, as a rule that "<span>Joel scores in 80% of his games.", the probability that he will score in 80% of his games is 1 - that is, we know it for sure</span>
Answer:
-2
Step-by-step explanation:
We have two points we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -11-1)/(-3 - -9)
= (-11-1)/( -3+9)
= (-12)/6
= -2
