Answer:
Quadruple the size
Step-by-step explanation:
Explanation:
When you enlarge a linear measurement by a scale factor a the area changes by a scale factor a2
So when you double the radius. scale factor 2, the area is increased by a scale factor:
22=4
So the area is quadrupled in this case.
Answer:
4
Step-by-step explanation:
-9x-6y=15
9x-10y=145
Find y first by eliminating the x.
Add the two equations together.
-9x+9x-6y+-10y=15+145
-6y+-10y=15+145
-6y-10y=160
-16y=160
divide both sides by -16 to get +y
-16y/-16=160/-16
y=-10
Use the substitution method to find x
-9x-6y=15
-9x-6(-10)=15
Do the bracket first
-9x+60=15
Move +60 to the other side. Sign changes from +60 to -60.
-9x+60-60=15-60
-9x=-45
Divide both sides by -9
-9x/-9=-45/-9
x=5
Answer:
( 5,-10)
