Answer:

$sum = (4 - 5)rxt - (8 + 6) {rx}^{2} + (1 + 2)x \\ = - rxt - 14 {rx}^{2} + 3x \\ \\ difference = (4 + 5)rxt + (6 - 8) {rx}^{2} + ( - 2 + 1)x \\ = 9rxt - 2 {rx}^{2} - x$

8-2w=6w-8 help lol!!!!!!!!!!!

NNADVOKAT [17]

W = 2. How do we find this out?

Put "w" as "2". 8-2(2)=6(2)-8
8 - 4 = 12 - 8.

Solve.

4 = 4

Hope this helps! ☺♥

The table below represents the velocity of a car as a function of time:

Naddik [55]

A)The y-intercept is 50 because when X=0, y=50. This shows that the car was moving at 50 mph as an initial speed.

B) in two hours (from 1 to 3) the speed increased by 4 miles per 2hours. (from 52 to 56). 4/2 = 2 mph, which is the average rate of change. This represents the amount of speed increased each hour.

C) y=2x+50, and y=60 in this case, so 60=2x+50
60=2x+50
-50 -50
-----------------
10=2x
5=x, so the domain is X<=5 (less than or equal to 5)

For each equation, find y when x=-3. Then find x when y = 2 1. y = 6x + 8

crimeas [40]

⬇ Hey, the answer is down below! :) ⬇

For y: x = -3

For y it stays the same.

For x: y = 2

For x it stays the same too.

For 1.): $x = \frac{1}{6}y + \frac{-4}{3}$

Step-by-step explanation:

For y there is no step-by-step explanation unfortunately.

For x there isn't a step-by-step explanation too unfortunately.

⬇ For 1.) there is a step-by-step explanation! ⬇

For step 1 we should flip the equations.

6x + 8 = y

For step 2 we should add -8 to both sides.

6x + 8 + − 8 = y + −8

= 6x = y − 8

For step 3 we should divide both sides by 6.

$\frac{6x}{6} = \frac{y - 8}{6}$

= x = $x = \frac{1}{6}y + \frac{-4}{3}$

In result we should have $x = \frac{1}{6}y + \frac{-4}{3}$ as the answer!

List all your possibility of outcomes (there are 36 outcomes) if you roll a dice containing numbers 1-6 two times. Determine the

Talja [164]

Check the table attached.

The first coordinates of each pair represent the 1.roll, and the second coordinates the 2nd, roll.

All the possible outcomes are {(1, 1), (1, 2).... (6, 5), (6, 6)}, a total of 36, as can be seen in the table.

Each outcome has a chance of 1 out 36 total possible outcomes of occurring.

So the probability is 1/36=0.02778
