x + 9 = 4(x-1)²
x + 9 = 4(x² - 2x + 1) Multiply (x - 1) times (x - 1)
x + 9 = 4x² - 8x + 4
4x² - 9x - 5 = 0 Subtract x + 9 from both sides

how do you solve this equation 19−4c=17
Answers
Answer: Whatever you do to one side, you do the same operation on the other. The goal is to get the variable alone with a number on the other side.
Here's how:
Step-by-step explanation:
19−4c=17
19 - 19 - 4c = 17 - 19 Subtract 19 from both sides 19-19 =0 Cancels on the left
-4c = 17-19 subtract: 17-19 = -2
-4c = -2
-4c/4 = -2/-4 Divide both sides by -4
Negatives divided by Negatives have a Positive quotient -4/-4 =1, Cancels

A pair of shoes costs $70.00. How much will the customer pay after 7% sales tax is added to the purchase?
Answers
Answer:
$74.90
Step-by-step explanation:
If $70 is your original price, you would need to multiply it by 1.07, because that is 107%.
Since the original price is 100% of the price, and sales tax is another 7% of the price, you are multiplying the original price by 107%, again making $74.90.

Last year during the July 4th holiday, Americans ate about 150,000,000 hot dogs. Over the entire year, Americans ate a total of about 2 x 10^10. Compute how many times greater the total number of hot dogs eaten by Americans last year was than the number of hot dogs eaten during the 4th of July holiday. Round your answer to the nearest one.
Answers
Answer:
133 times
Step-by-step explanation:
First, convert 2 x 10^10 out of scientific notation:
20,000,000,000
Since this is the total amount of hotdogs, divide by the number eaten on July 4th:
20,000,000,000 / 150,000,000 = 133.3333333
Round to nearest one: 133 times
The total number of hot dogs eaten by Americans last year is 133 times greater than the number of hot dogs eaten during the 4th of July holiday.
What is division?A division is a process of splitting a specific amount into equal parts.
We have,
The number of hot dogs that ate on 4th July holiday= 150,000,000
The number of hot dogs that ate last year = 2 x [tex]10^{10}[/tex]
The number of times the total number of hot dogs eaten last year than the number of hot dogs eaten during the 4th of July holiday is:
Number of hot dogs eaten in July x M = Number of hot dogs eaten in the entire year
150,000,000 x M = 2 x [tex]10^{10}[/tex]
M = 2 x [tex]10^{10}[/tex] / 150,000,000
M = 20,000,000,000 / 150,000,000
M = 133.33
Rounding to the nearest one we get,
M = 133
Thus the total number of hot dogs eaten last year is 133 times greater than the number of hot dogs eaten during the 4th of July holiday.
