5(8x-4)-10=40x-20-10

Answer:

0, Infinite Solutions

Step-by-step explanation:

First we distribute 5 to 8x and -4

40x - 20 - 10 = 40x - 20 - 10

Next, collect like terms

40x - 30 = 40x - 30

This equation has infinite solutions because on both sides of the equation the values are the same.

Just to check

Add 40x to both sides

-30 = -30

Add 30 to both sides

Then we get 0

The table shows interest owed for a home improvement loan based on how long it takes to pay off the loan.
Alexxandr [17]
Remember that  the formula for simple interest is:
I=prt
Where I is the interest to paid, p is the loan, r is the interest rate (in decimal), and t is the time (in years).

A. We know that the interest rate for a loan of 9 months is 2.9%, but we need to convert that rate to decimal. To do that just divide the interest rate by 100%:
\frac{2.9}{100} =0.029
Next, we are going to find the time t in years. Since the period of time is 9 months, we are going to dive by 12, the number of months in a year, to obtain the time in years:
t= \frac{9}{12} =0.75
Now, we just need to replace the values in our formula to find the interest owned:
I=(900)(0.029)(0.75)=19.58
We can conclude that <span>the interest owed for a home improvement loan of $900 after 9 months is $19.58.
</span>
B. Similarly:
r= \frac{3.1}{100} =0.031
t= \frac{18}{12} =1.5
I=(2500)(0.031)(1.5)=116.25
We can conclude that the interest owed for a home improvement loan of $2500 after 18 months is $116.25.

C. Similarly:
r= \frac{2.4}{100} =0.024
t= \frac{6}{12} =0.5
I=(5600)(0.024)(0.5)=67.2
We can conclude that the interest owed for a home improvement loan of $5600 after 6 months is $67.2

Plz help me!!! It's a lvl6 paper and i am not that lvl yet! It's just so he teachers know how inwill do and its calculator alowe
Rina8888 [55]
C=3N+425
N is the number of leaflets so you just substitute the required number for N.

C=3 \times 2500 + 425=7500+425=7925

The cost of printing 2500 leaflets is <span>£</span>7925.

I need help please help me
gulaghasi [49]

Answer:

A, B and D

Step-by-step explanation:

The zeros of f(x) are the points located on the x- axis, that is where y = 0

We can check which ones are the solutions by finding the zeros of f(x)

To find the zeros let f(x) = 0 , that is

(x² + 2x - 8)(x - 6) = 0 ← factorise the quadratic

(x + 4)(x - 2)(x - 6) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 2 = 0 ⇒ x = 2

x - 6 = 0 ⇒ x = 6

There are 3 zeros at x = - 4, x = 2, x = 6

These are located at A, B and D
