Mathematics
1 answer:
bogdanovich [222]3 years ago
4 0

Answer:

  (x, y) = (20, 449)

Step-by-step explanation:

When the equations are in this form, it is easiest to substitute one of the expressions for y into the other equation. That gives ...

  21.95x +10 = 22.45x

  10 = 0.50x . . . . . subtract 21.95x

  20 = x . . . . . . . . .multiply by 2

  y = 22.45x = 22.45·20 = 449

After which value of x does function g exceed function f
nalin [4]
We have that

for x=1
f(x)=1.5  and g(x)=-1
so
g(x) < f(x)

for x=2
f(x)=5  and g(x)=5
so
g(x)= f(x)

for x=3
f(x)=9.5  and g(x)=23
so
g(x) > f(x)

therefore

the answer is

I need please help. thank you
Travka [436]

15. She bought:

3 jeans, $20 each

1 pants, $18

You find the total: 3(20) + 1(18) = $78 then you apply the discount

Since this is between 50-100, you use the 38% discount (decimal form: 0.38)

38% is being subtracted from your total, so you can do this:

100% - 38% = 62%      This is your total after the discount

78(0.62) = 48.36   Your answer is C
