Y=5-2x
x^2 + (5-2x)^2 = 25
x^2 + 25-20x+4x^2 = 25
x^2 +4x^2-20x+25=25
5x^2 -20x=0
x=0 and y=5
Answer:
A
Step-by-step explanation:
10 and 8 are equal
11 and 15 are equal
due to the fact that the angles 10 and 11 but also 8 and 15 are supplementary, we know that they add up to be 180 degrees
180-42=138 degrees
and this means that angle 8 will also be 138 because of what we established earlier
Answer:
number = 24
Step-by-step explanation:
3 x 8 = 24
24 / 3 = 8
Diameter= 2 times the radius
2r=d
2r=10.2
R= 10.2/2
R=5.1
Therefore, the radius is 5.1 units which makes the answer choice C correct.
Hopefully, this helps!
The probability of Alyssa picking a nickel and a quarter would be 11/15 (eleven over fifteen)
6/15 plus 5/15 which is 11/15
You get 15 as the denominator because you add 6+4+5=15
I hope u understand.
