Which ordered pair is not a solution of the equation y = 2x – 1
F (3,5)
H (4,9)
G (9, 17)
J (6, 11)​

Answers

Answer 1

Answer:

H

Step-by-step explanation:

Answer 2
Answer: H

Explanation:

The format is (x,y) ; (4,9) Therefore, you plug in 4 for x then 9 for y. Which will give you “9=2(4)-1” and then simplify, which will give you.. “9=8-1 AKA 9=7” which is not accurate. Therefore that is NOT a solution to the equation...

STEP-BY-STEP:

y = 2x - 1

9 = 2(4) - 1

9 = 8 - 1

9 = 7

^^^^ NOT TRUE

So, therefore the answer IS H (4,9) because it’s asking what is NOT a solution.

A watercolor painting is 23 inches long by 11 inches wide. Ramon makes a border around the watercolor painting by making a mat that adds 1 inch to each side of the length and the width. What is the area of the mat?

Answers

Answer:

288 inches ²

Step-by-step explanation:

Water color painting

Length = 23 inches

Width = 11 inches

Mat that adds 1 inch to each side of the length and the width

Mat

Length = 23 + 1 = 24 inches

Width = 11 + 1 = 12 inches

What is the area of the mat?

Area of the mat = length × width

= 24 inches × 12 inches

= 288 inches ²

Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer. 1 inch =1578x 10-5 miles

Answers

Answer: (7.129)*10^(7) inches.

Step-by-step explanation:

We know that:

1 inch = 1.578*10^(-5) miles.

If we divide both sides by 1.578*10^(-5), we get:

(1/1.578*10^(-5)) inches = 1 mile

63,371.36 inches = 1 mile

Now, we have 1,225 miles, this is equal to 1,125 times 63,371.36 inches

Then 1,225 miles writen in inches is:

1,125*(63,371.36 inches) = 71,292,780 inches.

Now, to write this in scientific notation, we need to count the number of decimals between the first one at the left, and the decimal point.

In this case we have 7 decimals.

Now, let's take the first 4 decimals, (7129) and write a decimal point after the first one:

(7.129)

Now let's multiply this by then to the power of 7 (where 7 is the number of decimals we found above).

Then the scientific notation of 71,292,780 inches. is:

(7.129)*10^(7) inches.

What is the slope of the line that passes through the points (-2,-6) and
(14,-2)

Help please!!

Answers

Answer:

1/4 please put me the brainliest

Step-by-step explanation:

1. Slope
Slope: (Yb - Ya) / Xb - X-a
= (-2 - (-6)) / (14 - (-2)
= (-2 + 6) / (14 + 2)
= 4/16
= 1/4

2. Y-intercept
Y = mx + b
-6 = (1/4)(-2) + b
-6 = -0.5 + b
-6 + 0.5 = -0.5 + 0.5 + b
-5.5 = b
B = -5.5

Equation:
Y = 1/4x + -5.5
Y = 1/4x - 5.5

Jack and Jill applied for the same credit card from the same bank. The bank checked both of their FICO scores. Jack had an excellent credit rating, and

Jill had a poor credit rating


Jack was approved for a card with an APR of 12%. What was his monthly periodic rate?


Jill was approved for a card with an APR of 21%. What was her monthly periodic rate?


If each of them had an average daily balance of $700 and had to pay a finance charge, how much MORE will Jill pay than Jack?

Answers

Answer:

a. Jack's monthly periodic rate = 1%

b. Jill's monthly periodic rate = 1.75%

c. Amount paid more by Jill than Jack = $5.25

Step-by-step explanation:

a. Jack was approved for a card with an APR of 12%. What was his monthly periodic rate?

Jack's monthly periodic rate = Jack's annual percentage rate (APR) / Number of months in a year = 12% / 12 = 1%

b. Jill was approved for a card with an APR of 21%. What was her monthly periodic rate?

Jill's monthly periodic rate = Jill's APR / Number of months in a year = 21% / 12 = 1.75%

c. If each of them had an average daily balance of $700 and had to pay a finance charge, how much MORE will Jill pay than Jack?

Jack's finance charge = Jack's monthly periodic rate * Average daily balance = 1% * $700 = $7

Jill's finance charge = Jill's monthly periodic rate * Average daily balance = 1.75% * $700 = $12.25

Amount paid more by Jill than Jack = Jill's finance charge - Jack's finance charge = $12.25 - $7 = $5.25

For anyone who lived through the acrimonious1 politics of the 1790s, such foreboding thoughts did not seem out of place. Similar premonitions ran through the signal events of early American political history.Lincoln firmly took his stand in defense of the transcendent2 ideal of the Union as the sine qua non3 for the success of the American experiment in republican government. Indeed, as the conflict wore on, he spoke more and more frequently not just of the Union but of the nation. When he did speak of the Union, he presented it not as a means to an end but as an end in itself, something worthy of sacrifice in its own right.
