Answer:
p = 62
Step-by-step explanation:
(x^25)^2 = x^(25*2) = x^50. Then we have:
(x^12)(x^50) = x^(12 + 50) = x^62
Therefore, p = 62
X + y + z = 50
y + 10 = x, solving for y, y = x - 10
x = 2z, solving for z, z = x/2
Substituting for y and z,
x + x - 10 + x/2 = 50
(5/2)x - 10 = 50
(5/2)x = 60
x = (2/5) * 60 = 24
y = x - 10 = 24 - 10 = 14
Z = x/2 = 24/2 = 12
Checking:
x + y + z = 50, 24 + 14 + 12 = 50, 50 = 50. Solution meets the initial constraint.
Answer:
x = -2
Step-by-step explanation:
f(x) = 3x - 5
= 3(1) - 5
= 3 - 5
x = -2
Hello,
I suppose you keyboard is french shift "=" ===>"+"
f(x)=x²+9x+18
f(10)=100+90+18=198
f(-10)=100-90+18=28
rate=(198-28)/(10-(-10))=170/20=17/2
Answer: $14.75
I just did $0.75 x 7 = $5.25 and subtracted that from $20. Lmk if this helps or if my answer was incorrect!
