Answer:

a = 250x + 1300

Step-by-step explanation:

We have pairs (5, 2550) and (8, 3300)

Find the rate of change:

(3300 - 2550)/(8 - 5) =

750/3 =

250

$250 is the amount added to savings account every month

Initial amount was:

2550 - 5*250 =

2550 - 1250 =

1300

Since the change is linear and we have y-intercept and slope, we can show the amount after x months as:

a = 250x + 1300

How many solutions does the following equation has?
5 (m - 3) + 6 = 4m + 3

A-No Solution
B-Infinitely Many Solutions
C-One Solution

Answers

B should be the answer . Sorry if I’m wrong

Answer:

C. One Solution

That one solution is "m = - 6"

Step-by-step explanation:

5m - 3 + 6 = 4m + 3

Subtract 3 from each side:

5m - 3 - 3 + 6 = 4m + 3 - 3

5m + 6 = 4m

Subtract 6 from both sides of the equation:

5m + 6 - 6 = 4m - 6

5m = 4m - 6

Subtract 4m from both sides of the equation:

5m - 4m = 4m - 4m - 6

m = - 6

Answer:

Step-by-step explanation:

Hello There!

If you didn't know vertical angles are congruent

That being said we can use this equation to solve for x

40 = 5x

Objective: Isolate the variable using inverse operations

To get rid of the 5 we divide each side by 5

40 / 5= 8

5x/5=x

we're left with x=8

To check our answer we can plug in 8 to x and if it equal 40 then the answer is correct

5(8) = 40

So the answer would be 8

Step-by-step explanation:

Chuwawa

OWA OWA

The equation that relates the number of campers this year to the number of campers last year is c = 440 / 1.10

The number of campers last year is 400.

What are percentages?

Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred. Percentages are used to measure frequency.

Given that, a summer camp had 440 campers register this year, this is a 10 % increase over the number registered last year.

So,

The number of campers last year = number of campers this year / (1 + percentage increase)

440 / 1.1 = 400

Hence, the equation that relates the number of campers this year to the number of campers last year is c = 440 / 1.10 and number of campers last year is 400.

Please answer the following with 5 or more sentences:
The diameter of a circle is tripled. How does that affect the circumference? How does that affect the area? Explain.

Answers

Answer:

The formula for the circumference is 2πr. If you triple the radius the formula would be 2π3r. the ratio between the two is 2π3r / 2π1r. 2π & r cancels out and you have 3/1 left. Therefore the answer is the circumference is tripled.

The fact that there is no exponential in the formula indicates that the proportional increase is lineal.

The Circumference is 2πr.

When the radius is x, the circumference is 2πx

When the radius is tripled, it becomes 3x, to the circumference will be 2π(3x) = 6πx.

Soooooooo the circumference will also be tripled.

Step-by-step explanation:
