Answer: D

Step-by-step explanation:

You need a calculator for this cause the numbers are really large. I used a fx-9860GII Casio calculator. I put the equations on the graph mode. And then I got the x➡️0 for both equations.

I got x=0, y=5000 for the first equation

x=0, y=5200 for the new one.

You can see the y is (5200-5000)=200 more than the old equation. As the x is 0 for both that means the new one moved 200 up for the new one. It goes up cause its positive number .

I put the pictures so you can understand what I'm saying.

The amount of water dispensed by a water dispenser is normally distributed,

Contact [7]

Answer:

The correct answer is - C. 11.45 ounces to 11.75 ounces.

Step-by-step explanation:

According to the empirical rule of the distribution for 68% falls under the normal curve falls within 1 standard deviation of the mean.

That is:

μ±δ

From the given information, the mean is

μ = 11.60

and the standard deviation is

δ = 0.15

We substitute the given parameters to obtain;

11.60±0.15

11.75 and 11.45

This means the lower limit is

11.45

and the upper limit is

11.75

Why do you flip the equation when solving something like 10>-9x+10?

Karolina [17]

You flip the sign from > to < only when you are dividing by a negative number and in this case it would be negative 9.

Answer:

2t + 16

Step-by-step explanation:

1. 0 seconds and 16 feet.

$2(0) + 16$
$0 + 16$

$16$

2. 1 second and 18 feet.

$2(1) + 16$
$2 + 16$
$18$

3. 2 seconds and 20 feet.

$2(2) + 16$
$4 + 16$
$20$

4. 3 seconds and 22 feet.

$2(3) + 16$
$6 + 16$
$22$

5. 6 seconds and 28 feet.

$2(6) + 16$
$12 + 16$
$28$

Therefore, the answer is 2t + 16.

True or False:<br> There are an infinite number of answers for this equation:<br> 63 - X = 34

Shtirlitz [24]

Answer: No, the answer is 29, this is false.

Step-by-step explanation: 63-x=34

subtract 63 from both sides

34-63= -29

-x=-29

divide both sides by the negative and you get 29

plug in 29 for x, 63-29=34
