How to determine whether the pair of lines is parallel perpendicular or neither?

1 answer:

6 0

If the slopes of the 2 lines are equal then they are parallel.

If m1m2 = -1 (where m1 and m2 are the slopes of the 2 lines) then they are perpendicular.

If the 2 slopes do not match either the first or second conditions then they are neither parallel or perpendicular.

I need help!!!! Which represents the inverse of the function f(x)=4x?

Mrac [35]

Answer:

$h(x)=\frac{1}{4}x$ .

Step-by-step explanation:

The inverse is basically you just swapping x and y. People want to solve it for y to make it a function of x.

$y=4x$

Swap x and y:

$x=4y$

Now solve for y by dividing y on both sides:

$\frac{x}{4}=y$

$\frac{1}{4}x=y$

$y=\frac{1}{4}x$ .

Here's some of the info

~Evelyn has the greater mean.

~Evelyn’s objects generally landed farther away from the center than Robin’s.
~The object is to get the objects close to the center, so Robin is winning.

A candy store sells 7 packs of bubble gum for $29.33. How much would it cost to buy 3 packs?

alexira [117]

Hi there,

Recall how 7 packs for gum sell for $29.33.

Before we can calculate how much it would cost to sell 3 packs of gum, we must calculate how much it would first cost to sell 1 pack of gum.

The cost of 1 pack of gum is the current total cost divided by the total amount of gum packs you receive at that price.

In this case, the total cost is $29.33, and we receive 7 gum packs at that price.

Therefore, the cost of 1 pack of gum is $\frac{29.33}{7}$ , which equates to $4.19.

We now know that each pack of gum costs $4.19.

Hence, 3 packs of gum would cost three times that price.

$4.19 * 3 = 12.57$

The cost of 3 packs of gum is $12.57.

Hope that helps!

Q(9,10) . R(-5,2) . S(-8,-2) . T (-1,2) . Parallel or Perpendicular

SVEN [57.7K]

Answer:

Perpendicular

Step-by-step explanation:

Put all the points on a graph.

Parallel means that the lines that have the same slope and different y-intercepts. Lines that are parallel to each other will never intersect.

On the graph we made we can see that the lines will have to intersect because the points are in positions that no matter which points we chose to connect together, they would intersect with the other line.
