Answer:
-2.4
Step-by-step explanation:
3(1)-5y=15
3-5y=15
-3 -3
-5y=12
÷-5 ÷-5
y=-2.4
I'm sorry if it's incorrect! I tried!
Answer:
a c d
Step-by-step explanation:
a c d are quadratic equation expect "b"
The center of the circle is at (-2, 0). The radius is 5 units. The equation for a circle, in standard form is
.
We have our h and k from the center. h is the x coordinate and k is the y coordinate. The radius is 5. That means that the circle's equation, before simplifying, is
. After simplifying it is
. That's A and B. For C, we will simply pick points on the axes. One point on the circle is at (3, 0); another point is at (-2, 5); a third point is at (-7, 0). For D, the area of a circle is
.
For us that looks like this
. In terms of pi the answer is 25 pi, but in decimal form to the nearest square unit, it's 79 units squared.

Step-by-step explanation:
13.01 < 13.89
Step-by-step explanation:
similar shapes means that they have the same angles, and there is one scale factor that applies to all sides and other lines in the shapes (like heights).
therefore the ratios between 2 correlated lines are all the same.
so,
2/7 = 5/height
2×height / 7 = 5
2×height = 7×5 = 35
height = 35/2 = 17.5 in
