Substitute 2x + 14 for y in -4x - y = 4:
-4x - (2x + 14) = 4
-4x - 2x - 14 = 4
-6x - 14 = 4
-6x = 18
x = -3
Substitute -3 for x in y = 2x + 14 and -4x - y = 4:
y = 2(-3) + 14 --> y = -6 + 14 --> y = 8
-4(-3) - y = 4 --> 12 - y = 4 --> -y = -8 --> y = 8
So y = 8
At 200 miles, both company K and company B will pay $150.
To find half of 750, divide it by 1/2.
So,
750 ÷ 1/2
750/1 ÷ 1/2
750/2
= 375.
CROSS CHECK!
375 × 2 = 750.
1.
8 < x(7 - x)
We can now substitute the given values to see which one satisfies the inequality.
8 < 2(7 - 2)
8 < 10
A is the correct answer.
