Renee notices that her laptop is decreasing in value over time. She paid $1,160 for the laptop, and after 4years, she sees that it is worth $740.Find a linear function V(t) to model the value of the laptop as a function of t, where t is time in years.
Give your answer in the form V(t)=mt+b. Do not use a comma in any numbers.

Answers

Answer 1

Answer: Using the formula for slope, we can find out that $(1160 - 740) / (0 - 4) = - 105$ So -105 is the slope, and because she bought her laptop at $1160, the y-intercept is 1160. This means that the equation is V(t)=-105t+1160.

PLEASE HELP! THANKS! The measures, in degrees, of the 3 angles of a triangle are given by 2x +1, 3x - 3, and 9x. What is the measure of the smallest angle? A.) 13 degrees B.) 23 degrees C.) 29 degrees D.) 40 degrees please show how to solve this I GIVE THANKS!!!

Answers

So all of the internal angles of a triangle will add up to 180 degrees. So if we add all of the expressions given and set them equal to 180, we can solve for x, then solve for each angle...

(2x + 1) + (3x - 3) + 9x = 180
2x + 3x + 9x + 1 - 3 = 180
14x - 2 = 180
14x = 182
x = 13

Now we can substitute 13 into each expression to find the value of each angle...

2x + 1 =
2(13) + 1 =
26 + 1 = 27 degrees

3x - 3 =
3(13) - 3 =
39 - 3 = 36 degrees

9x =
9(13) = 117 degrees

So the 3 angles are 27 degrees, 36 degrees, and 117 degrees.

The smallest is 27 degrees

** Note-- I don't see 27 degrees in the answer choices you gave, so I double checked my math (I didn't find any mistakes). Please check to see that the question is written correctly (pay close attention to plus and minus signs).

Find two different ways to show how you know either 3/4 is greater than 2/3

Answers

You can change them into fractions with the same denominator: multiply 3/4 by 3 and 2/3 by 4

3/4 = 9/12
2/3 = 8/12

You could also convert them to decimals.
3/4 = 0.75
2/3 = 0.667

3/4 is greater than 2/3
