A line passes through the points (-100,-9.5•10^3) and (300,3.05•10^4). Find the value of y when x =200. Write answer in scientific notation.Please help asap with details and steps on how to solve.

Answers

Answer 1

Answer:

2.05x10^4

Step-by-step explanation:

The equation of the line is y=100x+500, which can be found through the given points.

So, if x=200, plug that into the equation of the line. y=100(200)+500

y=20000+500

y=20500

In scientific notation, that is 2.05x10^4

find the median: 10, 8, 14, 16, 13, 12.

Answers

Answer:

12.5

Step-by-step explanation:

10, 8, 14, 16, 13, 12

Organize the numbers from least to greatest

8, 10, 12, 13, 14, 16

Normally, the median would just be the number in the middle. However, because there are two numbers in the middle for this data set, add them and divide the sum by 2.

12+13=25

25÷2=12.5

Therefore, the median is 12.5.

What is (-3, -14) and (0, -9) written in slope intercept form? Thank you!

Answers

Answer:

Y= 5/3x + -9

Step-by-step explanation:

Well its

y=mx+b

m is slope

B is y intercept

To fidn y intercept, just make sure the X value of any coordiante given is 0 and the y value is not 0. So basically anything with (0, y), thats your y intercept.

Slope Is just

(y2-y1) / (x2-x1)

Answer:

y = 5/3x - 9

The equation for slope-intercept form would be y = mx + b.

Where y would be the total, m would be the slope, and b would be the y-intercept.

Garret invested $12,000 at an annual interest rate of 6%. How much money would Garret have had to invest at 10% so that the combined interest rate for both investments was 7% over the year?

Answers

Step-by-step explanation:

To determine how much money Garret would have had to invest at 10% in order to achieve a combined interest rate of 7% over the year, we can set up the following equation:

(12000 * 0.06) + (x * 0.10) = (12000 + x) * 0.07

Let's solve this equation to find the value of 'x', which represents the amount Garret would have had to invest at 10%:

720 + 0.10x = 0.07(12000 + x)

Simplifying the equation:

720 + 0.10x = 840 + 0.07x

0.10x - 0.07x = 840 - 720

0.03x = 120

x = 120 / 0.03

x = 4000

Therefore, Garret would have had to invest $4,000 at a 10% annual interest rate in order to achieve a combined interest rate of 7% over the year.

Garrett would have to invest 4000 at 10%

Dani experimented with a dollar bill and the copy machine a dollar bills length is 6.1 inches and width is 2.6 inches, she reduced the dollar bill so its length was 80% of its original size. What is the length of the copy of the dollar bill? please show how you figured it out. NO LINKS

Answers

Answer:

The length of the copy of the dollar bill is 4.88 inches in length and 2.08 inches in width.

Step-by-step explanation:

If Dani wants to make a smaller copy of a dollar bill and reduce its size to 80%, you will need to multiply the dollar bills original length by 8%.

80% = 0.8

0.8 x 6.1 = 4.88

80% = 0.8

0.8 x 2.6 = 2.08
