Answer:

See explanation below for all parts

Step-by-step explanation:

Your current slope (m) is -1/2 (the orange colored slope) so the "opposite" slope would be 2/1 or 2(the blue colored slope)

The answer for number 3 is y=2x+b.

For number 4, plug in the point values for x and y and solve for b. The point given is (-4,-5).

-5=2(-4)+b Now simplify

-5=-8+b then add 8 to both sides to isolate b

3=b or b=3

For number 9, you now know that m is 2 and b is 3

y=2x+3

matrenka [14]

To start you would count 140 miles and 90 miles and add that together because they are at least that far apart because they are in different directions with the measurement starting at the airport. So you have 230 miles. Then you would know that plan A is 3 miles up and plane B is only 2 miles up, so there's one more mile between them. So you can add that and say 231 miles.

F(x)=(x-2)^2<br><br> Evaluate for f(5)<br><br> Need Answers ASAP

borishaifa [10]

Answer:

Step-by-step explanation:

f(x) = ( x - 2)²

To find f(5) substitute the value of x that's 5 into f(x). That's for every x in f (x) replace it with 5

That's

f(5) = ( 5 - 2)²

= 3²

We have the final answer as

Find the balance on a deposit of $1,150 that earns 9% interest compounded annually for 2 years

valentinak56 [21]

P = 1150, r = 9% = 0.09 per year, n = 2 years.

A = P(1 + r)ⁿ

A = 1150(1 + 0.09)²

A ≈ 1150(1.09)² ≈ 1366.32

Marie and Jorge are both trying to lose weight. After 3 months they compared their weight loss. Marie’s weight went from 175 to

★━━━★━━━★━━━★━━━★━━━★━━━★━━━★━━━★

The answer to this is:

Jorge's weight percent decrease is (190-180)÷190, or amount of change/original amount. Simplified, 10 ÷ 190 = 5.2637157894...%, approximately equal to 5%. The first option is correct. Marie's percent decrease is (175-150)÷175. Simplified, that is 25÷175 = 14.2857142857...%, which is about 14%. The second option is correct. Clearly, we can tell that Marie had the greater percent change, about 14% to about 5%. Also clearly, Jorge did not have the greater percent change, so we can tell Option 4 is wrong. We already know that Jorge's change is about 5% and Marie's is about 14%, so they can't be about 0.5% or about 1.4%. Options 5 and 6 are incorrect. The correct answers are 1, 2, and 3.
