Answer:

The slope is 4/3x

Step-by-step explanation:

We can easily find the slope, by looking at the difference between each number on the table. We can see that the x values are rising in 3's, and the y values are rising in 4's. From that we can find the slope, 4/3x, since the slope rises up positive 4, and runs positive 3.

EDIT: forgot the x after the slope

How do you solve this problem?

Answers

Answer:

x = (1 + i)√2/2

Step-by-step explanation:

Simplify the left side and compare:

n ÷ (√2/2 - √2i/2) = nxn ÷ ((√2 - √2i)/2) = nxn × 2/√2(1 - i) = nxn × √2(1 + i)/(1 - i)(1 + i) = nxn ×√2(1 + i)/(1 + 1) = nxn × (1 + i)√2/2 = nxx = (1 + i)√2/2

Answer:

A. only inequality 1.

Step-by-step explanation:

The inequality 1 can be written as

- 5 - 1 = - 3d

- 3d = - 6

d = 2

Now the inequality 2 can be written as

- 1 =( 1 - d) / 3

- 3 = 1 - d

d = 1 + 3

d = 4

So the answer is A only inequality 1.

In the year 1984 the average American used to eat 55.7 pounds of chicken. This was 2.8 pounds more than the the year 1982 average. By what percent did chicken consumption increase from the year 1982 to the year 1984?

Answers

To solve this, we need to use the z statistic. The formula for z score is:

z = (x – u) / s

where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2

z = (90 – 90.6) / 17.2

z = -0.035

From the standard distribution tables:

P (z = -0.035) = 0.4860

Therefore there is about 48.60 % chance that it will be less than 90 pounds

Answer:

I think it increased by 0.05.

Step-by-step explanation:

If you subtract 2.8 from 55.7 you'll get 52.9. So I would divide 55.9 by 52.9 and get 1.05. I then would subtract 1.0

At a restaurant, the cost for one breakfast taco and one glass of milk is $2.10.

The cost for two tacos and three glasses of milk is $5.15.



How much would it cost for 3 tacos and 4 glasses of milk

Answers

Answer: $7.25

Step-by-step explanation:

Let T = taco cost

Let M = milk cost

T + M = 2.10

2T + 3M = 5.15

Multiply the first equation by (-2) and add it to the second equation

-2T - 2M = -4.20

2T + 3M = 5.15

M = 0.95

Plug this value for M in to the first equation

T + 0.95 = 2.10

T = 1.15

So a taco costs $1.15 and the milk costs $0.95

1.15 * 3 = 3.45

0.95 * 4 = 3.80

3.45 + 3.80 = 7.25
