Answer:
y=39
Step-by-step explanation:
73-2y=-5
2y=73-(-5)
2y=73+5
2y=78
y=78/2
y=39
Answer:
The radius of the circle A is times greater than the radius of circle B
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x----> the area of the clock A
y----> the area of the clock B
-----> equation A
we have
-----> equation B
substitute equation B in equation A
square root both sides
step 2
Find how many times greater is the radius of Clock A than the Clock B radius
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
Let
z-----> the scale factor
x----> the radius of the clock A
y----> the radius of the clock B
we have
substitute
therefore
The radius of the circle A is times greater than the radius of circle B
Ok so, this one is a confusing one for me but what I recomend is going on a website call desmos , they have a graphing area there and use y=-4x-7 if I’m right, I do not know so don’t trust me on this
