Hope this helps have a nice day:)
The tangent secant theorem says
PR × PS = PQ²
4 × (4+5) = PQ²
36 = PQ²
PQ=6
Answer: 6
It's multiplying by 2 each time 10 x 2 = 20, 20 x 2 = 40, 40 x 2 = 80.
C
Let x be the cost of banana
Michael: 4x=2.72
Divide by 4 : x =.68
Tonya: 6x= 4.08
x = .68 divide by 6
Answer:
the solution is (2, -6)
Step-by-step explanation:
Substitute the second equation into the first, replacing y in the first:
2x - (-4x+2) = 10
Simplifying, we get:
2x + 4x - 2 = 10, or:
6x = 12, which yields x = 2.
Substituting 2 for x in the second equation yields y = -4(2) + 2 = 0, or y = -6
Then the solution is (2, -6).
