What is the function rule for the line

Mathematics
1 answer:
ivolga24 [154]3 years ago
7 0

Answer:

The function rule is f(x) = 4x - 2.

Step-by-step explanation:

Using the points (2,6) and (0,-2) we see that the slope is

(6 - -2) / (2-0) = 8/2

= 4

Using the slope-intercept form y = m x + c    (where m = slope and c= y-intercept we see that :-

f(x) =  4x - 2

Expand and simplify 5(x-1)-3(x+4)
ludmilkaskok [199]
Question:

Expand and simplify 5(x - 1) - 3(x + 4)

Answer:

1.) Use the distributive property to solve this equation:

5(x - 1) = 5x - 5

3(x + 4) = 3x + 12

2.) Put it in the equation:

5x - 5 - 3x + 12

3.) Group them:

5x - 3x - 5 + 12

4.) Simplify:

2x - 7
which is the answer.



Hope this helped! :))

Which statement is true about the equations –3x + 4y = 12 and 1/4x –1/3 y = 1?The system of the equations has exactly one soluti
iren [92.7K]

Answer:

The system of the equations has no solution; the two lines are parallel.

Step-by-step explanation:

The equations have the same slope. In standard form, this can be seen as the same coefficients for x and y. We will multiply the second equation by -12 to reveal this.

\frac{1}{4} x-\frac{1}{3}y=1 \\-12(\frac{1}{4} x-\frac{1}{3}y=1)\\\frac{-12}{4} x-\frac{-12}{3}y=-12\\-3x+4y=-12

This means the equations are parallel and will never cross. There is no solution.

\implies2,520 +35 = 2,555

\implies 2,555 /5 = 511

\implies 511/60 = 8 \frac{31}{60}  = 8\text{hours}, 31 \text{minutes per day}
