Answer:

y = 2x + 20

y\geq 20

x\geq 0

Step-by-step explanation:

Vlad spent 20 minutes on history. Then Vlad spent 2 minutes on each math problem for homework, this is 2x. So in total, he spent 20+2x on homework. Depending on how many problems he did, the total time y can be found. This is the equation 20+2x=y.

If Vlad did 0 math problems then he spent at least 20 minutes on homework from history. This is the constraint y\geq 20.

We also know Vlad can do many math problems but the least amount he did was 0, so the second constraint is x\geq 0.

The police department uses a formula to determine the
laiz [17]

9514 1404 393

Answer:

  78.71 mph

Step-by-step explanation:

You're looking for the solution to ...

  d = 88

  0.0015r^2 +r = 88

  0.0015r^2 +r -88 = 0

Using the quadratic formula*, we find ...

  r = (-1 +√(1² -4(0.0015)(-88)))/(2×0.0015)

  r = (-1 +√1.528)/0.003 = 0.236123/0.003 = 78.7077

The speed of the car was about 78.71 mph.

_____

* The quadratic formula will also give a negative answer of about -745 mph, which is not relevant to the situation.

I need help it’s for a very hard test
Mumz [18]

Answer:

C

Step-by-step explanation

This has a factor of 6% or 0.06. But, you are adding and not subtracting so it is 1.06. ( If you multiply by a number less than 1 then it is actually dividing) So C is the only on that is correct.

Find the solution to the system of equations. 4x + 3y = –1 3x – 9y = 33
alexandr1967 [171]

Answer:

Step-by-step explanation:

4x + 3y = -1         --------------(i)

3x - 9y = 33        -------------(ii)

multiply equation (i) by 3

(i)* 3     12x + 9y = -3

(ii)       <u>   3x - 9y = 33</u>

add,       15x = 30

                 x = 30/15

                 x = 2

Put x =2 in Equation (i)

4*2 + 3y = -1

8 +3y = -1

     3y = -1-8

     3y = -9

       y = -9/3

       y= -3
