Mrs. Paige gave her daughter, Megan, $700 to open a savings account. Each month, Mrs. Paige gives Megan $25 to deposit into her

savings account.
Which equation can be used to find m, the number of months after opening her account when Megan will have $1,000 in her savings account?
25m + 700 = 1,000
25m - 700 = 1,000
700m + 25 = 1,000
700m + 25 = 1,000

Answer:

700 + 25m = 1000 is the correct equation

Step-by-step explanation:

In this question, we are tasked with finding the equation that represents the number of months m which in which megan will have $1000 in her account.

Now for her daughter, there are two kinds of ways she generates money for he account. The $700 see money her mother gave her and the $25 she has per month.

Thus after m months, the total she would have raised from the $25 each would be $25m

Now, we add this to the $700 see money and equate to $1000

Mathematically we have;

700 + 25m = 1,000

Answer:

35

Step-by-step explanation:

Put the numbers in the formula and do the arithmetic.

nCk = n!/(k!(n -k)!)

7C3 = 7!/(3!(7-3)!) = 7·6·5/(3·2·1) = 7·5 = 35

_____

It is convenient to use the largest of the factorials in the denominator to cancel as many factors as you can from the numerator, then cancel factors from the remaining numbers. Here after canceling 4! = 4·3·2·1 from the numerator, we are left with 7·6·5 divided by 3! = 3·2·1 = 6. Obviously, this will cancel the 6 in the numerator product, leaving only 7·5 = 35.

Some graphing and/or scientific calculators will have this function built in.

The cost of renting a car for a day is $0.50 per mile plus a $15 flat fee.
Vadim26 [7]

Answer: a) y=0.50x+15  

b) The graph of this equation form on a coordinate plane is a line.

c) Slope  =0.50 and y-intercept = 15

Step-by-step explanation:

Let x = Number of miles driven by car

Given: The cost of renting a car for a day is $0.50 per mile plus a $15 flat fee.

a) Total cost = 0.50x+15

If y =total cost of renting the car, then y=0.50x+15   (i)

b) Above equation is similar to y= mx+c  (ii) [m = slope , xc=y-intercept] which a linear equation .

So the graph of this equation form on a coordinate plane is a line.

c) Comparing (i) and (ii)

m=0.50 , c=15

Slope  =0.50 and y-intercept = 15
