F(x) = 1.5x + 50

if you use 5GB per month, you should pay
f(5) = 1.5(5) + 50 = $57.50

G(x) = 15 – 4x<br> h(x) = x +8<br> Write g(h(x)) as an expression in terms of 2.

Sergeu [11.5K]

For this case we have the following functions:

$g (x) = 15-4x\\h (x) = x + 8$

We must find $g (h (x))$ when $x = 2$ .

So:

$g (h (x)) = 15-4 (x + 8) =$

We apply distributive property to the terms within parentheses taking into account that:

$- * + = -\\15-4x-32 =$

We add similar terms taking into account that different signs are subtracted and the sign of the major is placed:

$-17-4x$

Thus, we have to:

$g (h (x)) = - 17-4x$

Then, with x = 2:

$g (h (2)) = - 17-4 (2) = - 17-8 = -25$

Equal signs are added and the same sign is placed.

Answer:

$g (h (2)) = - 25$

Brad has eight more nickels than quarters. Altogether he has $6.10. how many of each does he have

wlad13 [49]

Brad have 19 quarters and 27 nickels.

Step-by-step explanation:

Given,

Total worth of nickels and quarters = $6.10 = 6.10*100 = 610 cents

One quarter = 25 cents

One nickel = 5 cents

Let,

x represent the number of quarters.

y represent the number of nickels.

According to given statement;

25x+5y=610 Eqn 1

y = x+8 Eqn 2

Putting value of y from Eqn 1 in Eqn 2

$25x+5(x+8)=610\\25x+5x+40=610\\30x=610-40\\30x=570$

Dividing both sides by 30

$\frac{30x}{30}=\frac{570}{30}\\x=19$

Putting x=19 in Eqn 2

$y=19+8\\y=27$

Brad have 19 quarters and 27 nickels.

What is the principal which would amount to $6900 in 3 years at 5% simple interest per annum?

balu736 [363]

Answer:

$6000

Step-by-step explanation:

accumulated amount = A = PI

A = $6900

Let P = x

6900 - I = x

I = (x)(0.05)(3yrs) = 0.15x

6900 - 0.15x = x

Add

6900 = 1.15x

Divide, solve for x

x = 6000
