Your answer would be B. 5(x - 6). :)

The answer is B because 5 times x is 5x and 5 times 6 is 30. Since there is a subtraction sign, it would be equal to 5x-30

Write an equation for a line that is parallel to y + 5 = 3(x - 1) and goes through the point (3,-4)
MrRa [10]

Answer:

The  equation for a line that is parallel to y + 5 = 3(x - 1) and goes through the point (3,-4) will be:

  • y = 3x-13

Step-by-step explanation:

Given the equation

y + 5 = 3(x - 1)

Writing in the slope-intercept form

y=mx+b

where m is the slope and b is the y-intercept

y = 3(x-1) -5

y  = 3x-3-5

y = 3x - 8

Thus, the slope = m = 3

We know that the parallel lines have equal slopes.

So, the slope of a parallel line is also 3

Using the point-slope form of the line equation

y-y_1=m\left(x-x_1\right)

substituting the values m = 3 and the point (3, -4)

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

y+4 = 3x-9

y = 3x-9-4

y = 3x-13

Thus, the  equation for a line that is parallel to y + 5 = 3(x - 1) and goes through the point (3,-4) will be:

  • y = 3x-13

Which graph represents the linear function y = x 3/4– 4?
ahrayia [7]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=\frac{3}{4}x-4

This is a linear equation (the graph is a line)

To identify the graph find out the intercepts

<u><em>Find out the y-intercept</em></u>

The y-intercept is the value of y when the value of x is equal to zero

For x=0

y=\frac{3}{4}(0)-4=-4

The y-intercept is the point (0,-4)

<u><em>Find out the x-intercept</em></u>

The x-intercept is the value of x when the value of y is equal to zero

For y=0

0=\frac{3}{4}x-4

\frac{3}{4}x=4

x=16/3=5.33

The x-intercept is the point (5.33,0)

therefore

The graph in the attached figure
