Write a function rule for “The output is 6 more than five times the input.” Use x for the independent variable and y for the dep
Svetradugi [14.3K]

Answer:

y=5x+6

Step-by-step explanation:

+6 is six more than.

5x is five times the input.

For example, let's say x=3. you gotta multiply first so you can get the five times out of the way. 3×5=15. Now we got to add six because "6 more than" means to add six. so, 15+6=21. I plugged in 21 for y to check and I got x=3, so this works.

Alexandra [31]

Answer:

The answer is 743.4 square inches

Step-by-step explanation:

1. find the length-   2 x 40=80 cm

2. find the width-  1.5 x 40= 60cm

3. find area (Length x width)-  80 x 60= 4800 square cm

4. find length but in inches-   1in=2.54cm  length=80/2.54 = 31.5 inches

5. find width but in inches-  width= 60/2.54= 23.6 inches

6. Find area(length x width)-  31.5 x 23.6= 743.4 square inches

Which two lines are parallel?<br> Which two lines are perpendicular?
lana66690 [7]

Answer:

see explanation

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

All the equations given are in slope- intercept form

y = 2x + 1 → with m = 2

y = \frac{1}{2} x - 4 → with m = \frac{1}{2}

y = x + 1 → with m = 1

y = - \frac{1}{x} x - 3 → with m = - \frac{1}{2}

y = 10 + x → y = x + 10 → with m = 1

Thus

y = x + 1 and y = 10 + x are Parallel since both have m = 1

y = 2x + 1 and y = - \frac{1}{2} x - 3 are Perpendicular since 2 × - \frac{1}{2} = - 1
