Answer:

(D) a = 0, b = – 6

Step-by-step explanation:

x²  + (a + 1)x + b = (x - 2) ( x + 3)

= x² + x - 6

a + 1 = 1

a = 0

b = -6

Raj’s bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. The table shows that the amount of water remaining in the bathtub, y, is a function of the time in minutes, x, that it has been draining.

What is the range of this function?

all real numbers such that y ≤ 40

all real numbers such that y ≥ 0

all real numbers such that 0 ≤ y ≤ 40

all real numbers such that 37.75 ≤ y ≤ 40

Solve for x and y. What is m
irina [24]
3x + 2y + y - 3x = 180

3y = 180

y = 180/3

y = 60

3x = y - 3x

Let y = 60

3x = 60 - 3x

3x + 3x = 60

6x = 60

x = 60/6

x = 10

Answer: x = 10, y = 60

Help me pleaseeeee?!
den301095 [7]

Answer:

#1: -1.5, -0.5, 1/2, 1.5

#2:  -3, -1, 1.2, 2.3

Step-by-step explanation:

#1

First we have to figure out the correct order before we plot.

Find the biggest number:

looking at the number the biggest would be 1.5

Find the smallest number:

Looking at the number the smallest would be -1.5

Now that we have that we can easily figure out the rest...

(Going from least to greatest; like on a number line)

-1.5, -0.5, 1/2, 1.5 (That is how you will place the first one)

#2

(Use the steps from above to find the answer)

Biggest: 2.3

Smallest: -3

Order: -3, -1, 1.2, 2.3 (Placing on number line use that order)

Hope this helps :)
