A bus travels 300 kilometers at a given speed. If the speed is increased by 5 kilometers per hour, the trip will be reduced by two hours. Find the speed.

Slope = 2

Y intercept = -3

====================================================

Explanation:

We'll use the template y = mx+b

m = slope

b = y intercept

The y intercept always occurs when x = 0. In this case, b = -3 due to the first row of the table.

The slope is m = 2 because each time we increase x by 1, the y value goes up by 2.

So we can say

m = slope = (rise)/(run) = (change in y)/(change in x) = (2)/(1) = 2

Or we can apply the slope formula

m = (y2-y1)/(x2-x1)

using any two points of the table.

--------------------

Since we know m = 2 and b = -3, this means we get

y = mx+b

y = 2x+(-3)

y = 2x-3

Answer: See explanation

Step-by-step explanation:

7.) (0, 2)

Slope of (0, 2) and (-10, -16) = 2 - (-16) ÷ 0 (-10) = 18/10 = 9/5

8.) a. Slope of (17, -12) and (17, 8)

8 - (-12) ÷ 17 - 17 = 20 ÷ 0 = undefined

b. Slope of (6, -2) and (-3, 1)

1 - (-2) ÷ -3 - 6 = 3/-9 = -1/3

9.) (-3, 33) and (4, -9)

-9 - 33 ÷ 4 - (-3) = -42/ 7 = -6

10.)  Hourly: c = 75h + 15

c - charge

h - hours

1 hour

c = 75 (1) + 15

c = 75 + 15 = 90

The hourly charge for services is $90.

11.) C. A newborn weighs 8 pounds and gains 1.5 pounds each month for the next 3 months.

Answer:

SQ=128

Step-by-step explanation:

Answer:

The required function is:

[tex]C(x) = 150+0.45x[/tex]

Step-by-step explanation:

We have to represent the given scenario as an equation or function

Let x be the number of miles driven in a week

Let C(x) be the function of the number of miles driven

As it is given that charges are 150 per week, these charges are constant so they will be used as it is.

It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:

0.45x

Combining both terms, we get

[tex]C(x) = 150+0.45x[/tex]

Hence,

The required function is:

[tex]C(x) = 150+0.45x[/tex]

Step-by-step explanation:

- 12x + 10 = - 14

- 12x = - 14 - 10

- 12x = - 24

x = - 24 / - 12

x = 2

9 divided by 3 = 3

12 divided bye 3 = 4

Answer:

x = 3

Step-by-step explanation:

Since the two legs of the outer triangle equal the same (12), it is safe to assume the two legs of the inner triangle will equal the same. Therefore, x is equal to 3.

Answer: 36

Step-by-step explanation:

you multiply 9 by 4 to get 36.

Answer:

There are no simple factors to this expression.  You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process.  You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2.  We can however solve for x:

[tex]y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}[/tex]
