Help Due In An Hour!!

Answers

Answer 1

To find m, we can use the formula y2 - y1 / x2 - x1

x1 = 2

y1 = 50

x2 = 4

y2 = 90

Let's plug these numbers into our formula.

m = 90 - 50 / 4 - 2 = 40/2 = 20

So far our equation looks like: y = 20x + b

Now, let's plug one of the points into our equation.

50 = 20(2) + b

Simplify

50 = 40 + b

Subtract 40 from both sides.

10 = b

The final equation is: y = 20x + 10

A cell phone company charges $4 per GB beyond 20GB in a month. The monthly plan is $59.99, and the bill for January is $75.99. How many GB were used in that month?

Answers

Answer:

24GB

Step-by-step explanation:

75.99-59.99=16   This is how much extra money was paid.

16/4=4                   Divide this by the cost per GB.

20+4=24GB          Add the 20GB included in the plan.

Answer:

Step-by-step explanation:

75.99-59.99=16

$16 worth of GB used for that month

which means 16/4=4 GB extra were used that month beyond the 20 GB

so total GB usage for that month is 24 GB

muah

Answers

Answer:

565+9x=250.......

Step-by-step explanation:

um i think this might be it

Answer:

he worked 35 hours

equation: p= $9x + 250

p is pay

x is hours worked

Step-by-step explanation:

we know that the pay was 565 so plug that into p: 565= 9x + 250

subtract 250 from both side to isolate the variable: 315= 9x

divide both sides by 9: x= 35

Given the function f(x) = - 5x² – 13x – 5,
f(20) = ???

Answers

Answer:

-2265

Step-by-step explanation:

First, we replace x with 20.

[tex]f(20)=-5*20^2-13*20-5[/tex]

Then, we evaluate.

The * stands for multiplication.

[tex]f(20)=-5*20^2-13*20-5\\-5*400-260-5\\-2000-260-5\\-2265[/tex]

[tex]f(20) = - 5 \times {20}^{2} - 13 \times 20 - 5 \\ [/tex]

[tex]f(20) = - 5 \times 400 - 260 - 5[/tex]

[tex]f(20) = - 2000 - 260 - 5[/tex]

[tex]f(20) = - 2265[/tex]

Answers

Answer:

60 degrees

Step-by-step explanation:

40 degrees + 2y+20 degrees makes a straight angle. (from alternate interior angles postulate)

Thus, 2y+60 degrees = 180, or 2y = 120 degrees.

This means y = 60 degrees

Answer:

connor: Initial value is 200ft/ rate of change is 10

pilar: rate of change is -8/ initial value is 242

Step-by-step explanation:

so to figure out the initial value in a word problem, you need to see what it began or started with first and in the table to figure out the initial value, you need to see if there's a zero in the input and under the zero, the number in the output that's under 0 is the initial value. to find the rate of change in a word problem, if it says per, each, then it's the rate of change, Also to find the rate of change in a table you need to use this formula y²- y¹/x²-x¹ for example 234-242/1-0= -8/1 which is -8 for the slope. I hope my explanation helped. sorry if it's not clear

A cyclist rode at a constant speed of 21mph for 3 hours. Then she decreased her rate of speed to 17 mph for 4 hours. How far fid they cyclist ride in 7 hour

Answers

Answer: 131 miles; 21 x 3 = 63 + 17 x 4 = 68. 63 + 68 = 131 miles

Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.

What is the speed?

The magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Here given that,

A cyclist rode at a constant speed of [tex]21[/tex]mph for [tex]3[/tex] hours. Then she decreased her rate of speed to [tex]17[/tex] mph for [tex]4[/tex] hours.

[tex]21[/tex] x [tex]3[/tex]  [tex]=63 + 17 (4)[/tex]
