Answer:

-14

Step-by-step explanation:

if the temperature is 12 at the beginning and there is a -26 temperature change you subtract 12 by -26

12-(-26) = 14

or

you take 26 and subtract 12

26 - 12= -14

and now you have a temperature of 0 with -14 to go so you get -14

The temperature after the storm is = - 14 F

We have temperature at Wonder Lake which is 12 F and during a storm, the temperature changes by  - 26 F.

We have to determine the temperature after the storm.

A temperature of y degrees below zero means that the temperature of an area is equal to = - y degrees i.e., T = 0 - y = - y.

According to question -

Initial Temperature T(i) = 12 F

Let the final temperature T(f) = x

Change in temperature ΔT = T(f) - T(i) = x - 12

- 26 = x - 12

x = - 26 + 12

x = - 14 F

Hence, the temperature after the storm will be = - 14 F

Answer: The answer would be

D - 12.25x + 3.99 = 77.49

Step-by-step explanation:

If each shirt costs $12.25, that would be 12.25 times “x” amount of shirts. Then, you add the $3.99 shipping amount. Which all equals 77.49.

Step-by-step explanation:

The quotient of given numbers is 6.4.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given that, dividend =70.4 and divisor=11.

The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

Here, 70.4/11

= 6.4

Therefore, the quotient is 6.4.

Answer:

A. Slope is -5. Y-intercept is (0,7)

Step-by-step explanation:

1. Find the slope using the slope formula and the coordinates

Remember, the slope formula is: y2-y1/x2-x1

You'll use the coordinates (0,7) (4, -13) to plug into the formula.

-13-7/4-0

= -20/4

= -5

Slope is -5

2. Find the y-intercept.

First, write the equation of the line in point-slope form: y-y1=m(x-x1)

M is slope and y1 and x1 can be from any ordered pair (as long as they're from the same one). Let's use (0,7)

y-7=-5(x-0)

Simplify the equation.

y-7=-5x+0

y=-5x+7

3. Now the equation is in y-intercept form, or y=mx+b. Again, M is slope. B is the y intercept. So, the y-intercept is 7

The equation of a line is y = 50x. Then the slope of the line is 50 meters per minute.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

Jenna can swim 150 meters in 3 minutes.

If you graph this with minutes on the X-axis and meters on the Y-axis.

Then the slope of the line will be

m = 150 / 3

m = 50 mters per minute

Then the equation will be

y = 50x

Answer:

Yes, it is possible to have a percent increase greater than 100%. The retail price of the clubs is $750

Step-by-step explanation:

Because the clubs were marked up 200%, we need to add 200% to 100%.

Then to find the retail price, we have to multiply 300%(3) by the wholesale price of $250.

Retail price = 3(250) =750

Therefore, the retail price is $750

No, a triangle cannot have lengths of 2, 2 and 18

Step-by-step explanation:

The sum of 2 sides of a triangle must be greater than the third side.

So according to the question:

we find that 2+2 is not greater than 18

hence a triangle cannot have lenghts 2,2 and 18
