Complete the statement for the equation y=-1/2x-1/2.
Enter the correct answer in the box.
The graph crosses the y-axis at (0,?)

Answer:

y > 4x - 2

Step-by-step explanation:

y-intercept is at -2

slope is rise by 4, run by 1

if you don't know where to shade, select a point and plug it in to see if T or F

example (0, 0)

is 0 > 4(0) - 2

is 0 > -2  True, so shade to the left because this is where (0,0) is

Answer:

Step-by-step explanation:

Analyze what each part of the inequality means mathematically.x is the solution of the problem, the quantity you are looking for.6x means that, for a reason given in the problem, the quantity you are looking for is multiplied by 6.− 18 means that, for a reason given in the problem, 18 is subtracted from 6x.≤ 18 means that after multiplying the solution x by 6 and subtracting 18 from it, the result is at most 18.Think of some different situations in which a quantity x might be multiplied by 6.You plant 6 seeds from x different seed packets, and you want to know from how many different seed packets you plants seeds.Build on the situation and adjust it to create a verbal description that takes all of the information of the inequality into account.Elrich planted 6 seeds from each of x different seed packets in his garden. To plant these seeds, he had to remove 18 plants that were already in the garden. Including the plants he removed and the seeds he planted, he expected to have at most 18 plants in the garden. From how many different seed packets did Elrich recently plant seeds?

Answer:

B.

Subtraction property of equality.

Answer:

a. The mean of uniform distribution is (a+b)/2, where a and b are limits of the uniform distribution.  So, mean is (0+12)/2 = 6 minutes

b. Standard deviation is (a-b)^2/12 = (0-12)^2/12 = (-12^2)/12 = 144/12 = 12

c. Prob (Wait for more than 5 min) = (12-5)/(12-0) = 7/12 = 0.5833

d. So, given he has waited for 2.8 minutes, what is prob that he will wait between 3.4 and 5.7 minutes

= (5.7 - 3.4) / ((12-2.8) - 0)  

= (5.7 - 3.4) / (9.2 - 0)

= 2.3/9.2

= 0.25

e. 10% of all customers wait at least how long for the train?

10% of all customers wait for?

Since its a uniform distribution, people are uniformly spread. So, the 10% of people will be in the top 10% percentile group of waiting time which essentially means:

0.10 = (12-b)/(12-0)

0.10 = (12-b)/12

1.2 = 12 - b

b = 12 - 1.2

b = 10.8 minutes

So, 10% of all customers wait for at least 10.8 minutes for the train.

Answer:

You invested $22,000 in two accounts paying 3% and 5% annual interest, respectively. If the total interest earned for the year was $980, how much was invested at each rate?

Step-by-step explanation:

let x=amt invested at 3% rate of interest.

22000-x=amt invested at 5% rate of interest.  

.03x+.05(22000-x)=980

.03x+1100-.05x=980

.02x=120

x=6000

22000-x=16000

amt invested at 3% rate of interest=$6,000

amt invested at 5% rate of interest=$16,000

The amount invested in the account that yields 3% interest is $21,000 and the amount invested in the account that yields 2% interest is $5000

This can be solved using simultaneous equations. Two equations can be derived from the question :

a + b = 26,000 equation 1

0.02a + 0.03b = 730 equation 2

Where

a = amount invested in the account that yields a 2% interest

b = amount invested in the account that yields a 3% interest

Multiply equation 1 by 0.02

0.02a + 0.02b = 520 equation 3

Subtract equation 3 from equation 2

0.01b = 210

Divide both sides of the equation by 0.01

b = 210 / 0.01 = 21,000

Substitute for b in equation 1

a + 21,000 = 26,000

a = 26,000 - 21,000

a = 5000

The equivalent of the expression, 35 (8 – 3)  is (35 × 8 ) - (35 × 3). The answer is C.(35 × 8) – (35 × 3)

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.

Therefore, let's simplify the expression to the its' equivalent as follows:

Hence,

35 (8 – 3) = 35(5) = 175

Therefore,  the equivalent is as follows:

35 (8 – 3)

Open the bracket by multiplying as follows;

35 (8 – 3)  = (35 × 8 ) - (35 × 3)

The correct option is C. (35 × 8) – (35 × 3)

Answer:  In 20 minutes, tanks A and B will each have 120 gallons remaining in them.

Step-by-step explanation:

The equation, the amount at which they will be equal, represents the given starting amounts minus the gal/min times the unknown time in minutes, m.

220 - 5m = 180 - 3m Subtract 180 from both sides; add 5m to both sides.

220-180 -5m +5m = 180-180 +5m - 3m  Combine like terms

40 = 2m  Divide both sides by 2

20 = m

Check: Substitute 20 for m in the equation

220 - 5(20) = 180 - 3(20)

220 - 100 = 180 -60

120 = 120   True!

Answer:

  $6420

Step-by-step explanation:

The account value can be found using the formula ...

  A = P(1 +rt)

where P is the initial deposit, r is the annual rate, and t is the number of years.

  A = $6000(1 + .035×2) = $6000(1.07) = $6420

The total amount after 2 years is $6420.

Answer:

A - 152

Step-by-step explanation:

You see the box on the right triangle, meaning it is 90.

Add 90 + 62 to get 152, so the angle is 152.

The numerator of a fraction equivalent to 3/4 that has a denominator of 20 is 15.

A fraction is made up of a numerator and a denominator. Examples of fraction are: [tex]\frac{3}{4} , \frac{1}{2}[/tex]. The numerators are 3 and 1. The denominators are 4 and 2.

In order to determine the numerator, we have to determine the relationship between the two denominators given ( 20 and 4). 20 is a multiple of 4. 20 / 4 = 5. The second step is to multiply 3 by 5 = 3 x 5 = 15.
