Answer:
1)
Y-intercept: -3
Slope: 2
Equation: y = 2x - 3
Step-by-step explanation:
I just answered one since it was only for 5 points. :)
s = 2j + 3.
For instance, if addie was 5, you could find the sum of their ages by substituting her age into the formula.
s = 2(5) + 3
S = 13
Answer:
<u>Sherri has the account since twelve years ago</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Current balances of Sherri's account = $ 1,050.80
Initial deposit = $ 740
Interest rate = 3.5% simple interest = 0.035
2. How long has Sherri held the account?
Let's recall the formula of the simple interest:
FV = P * (1 + rt), where FV is the future value of the investment or initial deposit, P, the initial deposit, r, the interest rate and t, the number of periods.
Replacing with the values we have:
1.050.80 = 740 * (1 + 0.035t)
1,050.80 = 740 + 25.9t
1,050.80 - 740 = 25.9t
310.80 = 25.9t
t = 310.80/25.9
t = 12
<u>Sherri has the account since twelve years ago</u>
Answer
• A. Equation: 25(5 + x) = 325
,
• B. Answer: 8 dogs
Explanation
Given
• Charge to wash a dog: $25.
• She washed 5 dogs on Saturday and then some more on Sunday.
• She made $325 for the weekend.
Procedure
She charges $25 per wash, she made $325 for the weekend, and we know that on Saturday she washed 5 dogs, but we don't know how many she washed on Sunday. Thus, we have to build an equation in which the number of dogs washed on Sunday is represented by x (as we do not know the real number).
Considering that the total money made has to be equal to the multiplication of the charge times the dogs washed, the equation is:
Then, we have to solve for x to know how many dogs did she wash on Sunday.
0. Multiplying the parenthesis
<em>2. Subtracting 125 from both sides of the equation</em>
<em>3. Dividing both sides of the equation against 25</em>
F(x)=95x written as a function of x
