Answer:

(2, -3)

Step-by-step explanation:

Apparently, the equations are supposed to be ...

4x +y = 5
3x +y = 3

The solution for x can be found by subtracting the second equation from the first:

(4x +y) -(3x +y) = (5) -(3)

x = 2 . . . . . . . matches the second answer choice

Y can be found from either equation:

y = 5 - 4x . . . . . subtract 4x from the first equation

y = 5 -4(2) = -3

The solution is (x, y) = (2, -3).

A car enters a turnpike 22 miles north of the town. The car travels north at an average speed of 60 miles per hour. How far is t

QveST [7]

Answer:

y = 60x + 22

262 miles

Step-by-step explanation:

Given that the car enters the turnpike at 22 miles, his initial starting point, or initial value (b) is 22. You also know the rate at which the car travels is 60 miles per hour, which is the slope (m). Using the slope-intercept formula of a linear function: y = mx + b, you can plug in your initial value and rate:

y = 60x + 22, where y = the total miles and x = the number of hours traveled

After 4 hours:

y = 60(4) + 22 = 240 + 22 = 262 miles
