X/-4=-3 show your work

Answers

Answer:

x = 12

Step-by-step explanation:

(x)/(-4) = -3

To solve this equation, simply take the denominator from the fraction on the left side of the equation to the right side of the equation and multiply it with the constant.

Also, do not forget to multiply the signs as both the numbers are negative so the number will become positive after multiplication:

x = -3 × (-4)

x = 12

Therefore x is equal to 12.
x/-4=-3
x=-3(-4)
x=12

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

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.

Is 28/81 less than 7/9.Is 28/81 less than 4/9?

Answers

28/81 is less than 7/9

28/81 is less than 4/9

The common denominator is 81, so you say 9 can go into 81 nine times, so you multiply 9 by the numerator, so 7/9 is now 63/81 an 4/9 is now 36/81
