Answer:
12 miles
Step-by-step explanation:
1/2 inch per 2 miles
3 inches away
3 ÷ 1/2 = 6
6 * 2 = 12

Answer:
(A) y - x
Step-by-step explanation:
Finding a:
- ax + x² = y² - ay
- ax + ay = y² - x²
- a(x+y)= (y+x)(y-x)
- a = y - x
Correct choice is (A)
Answer:
The lines are parallel.
Step-by-step explanation:
Given the lines
![-2x-3y=9](https://tex.z-dn.net/?f=-2x-3y%3D9)
![4x+6y=24](https://tex.z-dn.net/?f=4x%2B6y%3D24)
Writing the equations in the slope-intercept form
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where m is the slope and b is the y-intercept
![-2x-3y=9](https://tex.z-dn.net/?f=-2x-3y%3D9)
![y=-\frac{2}{3}x-3](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B2%7D%7B3%7Dx-3)
Thus, the slope = m₁ = -2/3
also
![4x+6y=24](https://tex.z-dn.net/?f=4x%2B6y%3D24)
Thus, the slope = m₂ = -2/3
- We know that parallel lines have equal slopes
As
m₁ = m₂
Thus, the lines are parallel.
Answer:
70x³ - 73x² - 155x + 168
Step-by-step explanation:
Given
(5x - 7)(2x + 3)(7x - 8) ← expand the first pair of factors using FOIL
= (10x² + x - 21)(7x - 8)
Each term in the second factor is multiplied by each term in the first factor, that is
10x² (7x - 8) + x(7x - 8) - 21(7x - 8) ← distribute the 3 parenthesis
= 70x³ - 80x² + 7x² - 8x - 147x + 168 ← collect like terms
= 70x³ - 73x² - 155x + 168
