Answer:

y= 125x + 5o

Step-by-step explanation:

Since the constant is 125 we add the x to show each broom he makes. The one time fee is not a constant so therefore it will only be added once.

Answer:

f(x)=125g+50

Step-by-step explanation:

He is charging $125 for each gold piece so you would multiply “g” and 125.

You would add 50 as a one time fee so you add 50.

Factor the denominator of the rational function y= 2x/x^2-16
lina2011 [118]

x^2-16 factors to (x-4)(x+4)

You use the difference of squares rule here which is

a^2 - b^2 = (a-b)(a+b)

For what value of y does 125=(1/25)^y-1
Alex777 [14]

Answer:y=-1/2

Step-by-step explanation:

125=(1/25)^(y-1)

5^3=(5^(-2))^(y-1)

5^3=5^(-2(y-1))

The same base eliminate each other we then have

3=-2(y-1)

3=-2y+2

Collect like terms

2y=2-3

2y=-1

Divide both sides by 2

2y/2=-1/2

y=-1/2

Jane wants to save money to buy a motorcycle. She invests in an ordinary annuity that earns 4.2% interest, compounded quarterly.
Sauron [17]

Answer:

she need to pay is $550.40

Step-by-step explanation:

given data

interest = 4.2 % compounded quarterly = 0.042 / 4 = 0.0105

future value = $7000

time = 3 year = 3 × 4 = 12 months

to find out

How much money she need to pay

solution

we will apply here formula for future value for compound quarterly

that is

future value = principal × \frac{(1+r)^{t} -1 }{r}    .............1

put here all these value

future value = principal × \frac{(1+r)^{t} -1 }{r}

7000 = principal × \frac{(1+0.0105)^{12} -1 }{0.0105}

principal = 550.40

so she need to pay is $550.40
