Rule 1. Adding/subtracting the same number on both sides.

   Example: The inequality x-2>5 has the same answer as the inequality x > 7.

Rule 2. Switching sides and changing the orientation of the inequality sign.

   Example: The inequality 5-x> 4 has the same solutions as the inequality 4 < 5 - x.

The graph shows a proportional relationship. Which equation matches the graph.

A. y = 1/5x

B. y = x

C. y = 15x

D. y = 5x​

Answers

Answer:

D

Step-by-step explanation:

When x = 1, y = 5

When x = 3, y = 15

So, using this, find the slope.

(15 - 5) / (3 - 1) = 10 / 2 = 5

For every x, y increases by 5.

So, y = 5x, or D

Answer:

D

Step-by-step explanation:

5x

We need a rock garden with a perimeter of 12 feet and an area of 8 square feet


Length: Feet
Width: Feet​

Answers

Answer:

Length: 4 feet

Width: 2 feet

Step-by-step explanation:

The only possibilities that could get an area of 8 feet are 4 x 2 and 8 x 1

However, it has to be 4 x 2 because the 8 x 1 dimension won't have a perimeter of 12 feet.

The dimensions of 4 x 2 will have an area of 8 square feet, since 4(2) = 8

It will also have a perimeter of 12 feet because 4 + 4 + 2 + 2 = 12

So, the length is 4 feet and the width is 2 feet

Jayden has $10 in a savings account. The interest rate is 5%, compounded annually.

$
Submit

Answers

Answer:

$1

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 10 × 0.05 × 2 = 1

I = $ 1.00

The simple interest accumulated

on a principal of $ 10.00

at a rate of 5% per year

for 2 years is $ 1.00.

Answer:

y=-2x+8

Step-by-step explanation:

So I select 2 points:

(0,8) and (4,0)

so then I find the slope.

m = [tex]\frac{8-0}{0-4} \\=\frac{8}{-4} \\=\frac{2}{-1} \\=-2[/tex]

m = -2

Then the b (y-intercept) is 8, so equation is:

A college student takes the same number of credits each semester. She had 12 credits when she started, and after 6
semesters, she had 96 credits.
Which of these expresses the rate at which she is earning credits?

Answers

Answer:

x = 14

Step-by-step explanation:

Credits = 12  Semesters = 6   Total Credits = 96

6x = 96 - 12

6x = 84

Divide 6x = 84 by 6.

x = 14

[tex]\frac{96 credits-12 credits}{6 semesters} =\frac{84 credits}{6 credits} = \frac{14 credits}{1 semester}[/tex]

can someone help me with this I am stuck

Answers

Because you know the angle in the middle is 91 degrees, the other one is too.
Triangles have 180 degrees:
180-41-91 = 48.
48 degrees!
45+44=89
180-89=91
41+91=132
180-132=48
so the answer is 48

does 5+4=8 and does 1+1=2​

Answers

Answer:

5 + 4 = 8 (False)

1 + 1 = 2 (True)

Step-by-step explanation:

First Case:

5+4=8

No this is not correct as when 5 is added to 4 then the result should be - (1+1+1+1+1) + (1+1+1+1)

= 1 + 1 + 1 + 1 + 1 + 1 + 1 +1 +1

= 9

So this is not correct.

Second Case:

1 + 1 = 2

Yes this is correct when 1 and 1 are added for two times it results in 2.

The manufacturer of a low-calorie dairy drink wishes to compare the taste appeal of a new formula (formula B) with that of the standard formula (formula A). Each of four judges is given three glasses in random order, two containing formula A and the other containing formula B. Each judge is asked to state which glass he or she most enjoyed. Suppose that the two formulas are equally attractive. Let Y be the number of judges stating a preference for the new formula. a Find the probability function for Y . b What is the probability that at least three of the four judges state a preference for the new formula

Answers

Answer:

a) [tex]P_y = \frac{4}{y} * \frac{1}{3}^y * \frac{2}{3}^{4-y}[/tex]

b) 0.033

Step-by-step explanation:

Let Y represents the number of judges preferring a formula.

There are total four judges and each judge can select either A or B

n = 4, p = 1/3

a) The probability function is

[tex]P_y = \frac{4}{y} * \frac{1}{3}^y * \frac{2}{3}^{4-y}[/tex]

b)

Substituting the value of y -3 in above equation, we get -

[tex]P_3 = \frac{4}{3} * \frac{1}{3}^3 * \frac{2}{3}^{4-3}\\= \frac{4}{3} * 0.037 * 0.67\\= 0.033[/tex]

Question 1 of 10
The graphs below have the same shape. What is the equation of the red

g(x) =

Answers

The equation of the red graph is g(x)= 1-x^2.

Notice how on the blue graph all the lines pass through where 4 falls on the graph. This is the same for the red line except they all past through 1. Therefore you should change the 4 in the equation of the blue line to a 1 so it represents the redline.
