Answer:

C

Step-by-step explanation:

Firstly, we have 1/x as the parent function. 1/x-1 describes the graph of 1/x to shift 1 unit right. -1/x-1, states that it is reflected across the x-axis. And -1/x-1 -10 states that it is shifted 10 units down.

olya-2409 [2.1K]

Answer:

Step-by-step explanation:

y = e^(-3x)

Stretch by factor of 4

y = 4e^(-3x)

Reflect across y axis

y = 4e^(3x)

Shift up by 5

y = 4e^(3x) + 5

Which associations best describe the scatter plot?
LenKa [72]

Answer: Here you go hope this helps

If a line is drawn through (twenty, seventy) and (twenty-five, sixty), then you can use the points in getting the equation.

Slope is = (60-70)/(25-20) = -2

Using the two-point slope form, y – y1 = m(x – x1)

               y – 70 = -2(x – 20)

               y – 70 = -2x + 40

               y = -2x + 110

Find an equation for the line perpendicular to 4x+12y=72 and goes through the point (-9,6)
il63 [147K]

Answer:

Step-by-step explanation:

Given the equation

4x+12y=72

The equation of a line can written as

y=mx+c

Where m is the slope

And c is the intercept on y axis

Then, we need to write the equation given in the form of equation of a line (y=mx+c), by making y subject of the formula

4x+12y=72

12y=-4x+72

Divide through by 12

y=-4x/12 + 72/12

y=-⅓x+6

Then, comparing with equation of a line shows that

m=-⅓ and c=6

So we need to get another linen that is perpendicular to this line and passes through the point (-9,6)

The slope of the line perpendicular to another line is given as

m1=-1/m2

Then, m1=-1÷-⅓

Then, the slope of the perpendicular line is 3

Then, m=3

So apply this to equation of the line

y=mx+c

Then, y=3x+c

So to know c, we will insert the point given(-9,6), x=-9 and y=6

y=3x+c

6=3(-9)+c

6=-27+c

Then, c=6+27

c=33

Then, the equation of line becomes

y=3x+33
