Answers

Step 1: Subtract 5 from both sides.

3w + 5 − 5 ≥ 11 − 5

3w ≥ 6

Step 2: Divide both sides by 3.

3w /3  ≥  6 /3

w ≥ 2

Therefore, the correct answer is w ≥ 2 .

Here is the graph for one equation in a system of equations:


Match the correct equation to the scenario.

Write a second equation for the system so it has infinitely many solutions.

a) y=-3/4x+4

b) y=-3/4x+2

c) y=-3/4x+1

Write a second equation whose graph goes through (0, 1) so the system has no solutions.

a) y=-3/4x+4

b) y=-3/4x+2

c) y=-3/4x+1

Write a second equation whose graph goes through (0, 2) so the system has one solution at (4, 1).

a) y=-3/4x+4

b) y=-3/4x+2

c) y=-3/4x+1

Answers

Answer:

Step-by-step explanation:

1. y = -3/4 +4 cause that is the same line as the equation and since they are the same line it would mean there would be infinitely many solutions.

2. y=-3/4x+2 if you graph this line next to the orginal line it runs through (0,1) and you can see that its paralellel and will never meet the other line so there will be no solutions

3. for this question im confused because none of the answers fits the line that the question is asking for the closest would be y= -3/4x+2 since it runs through (0,2) but other than that none of the answers fit the line its describing.

an equation that would work though would be y=-1/4x+2

Choose the correct answer

Answers

Answer:

Its c. c = 50.

Step-by-step explanation:

First, we need to figure out what the equation equals.

7 + 7/7 + 7*7 - 7 = x

PEMDAS

Parentheses, exponents, division/fraction, addition, subtraction.

7/7 = 1. So equation changed into 7 + 1 + 7*7 - 7 = x.

7*7 = 49. So equation changed again into 7 + 1 + 49 - 7.

Lets calculate it. 7 + 1 = 8 + 49 = 57 - 7 = 50. x = 50.

c is the only one who has a calculation of 50.

Answers

Answer:

See explanation

Step-by-step explanation:

So, the angle for QRS is the interior angle of R. The exterior angle outside of angle R is for the equation you are going to use. Because angle R is on a straight line, the interior angle of R plus the exterior angle of R will equal 180 degrees. From there you should be able to calculate the rest of the angles, I believe you should be able to calculate y first.

All of the angles in a triangle add up to 180. From there you make an equation which would give you the value of y.

We know that the bottom line is straight, so it equals 180*. QRS is supplementary to the R* angle, which is 144*. All supplementary angles add up to 180, so 180-144 would give us 36* for the Value of QRS.

Now we know QRS=36* and the sum of all the angles is 180, we can write the equation
6y + 36 =180
y= 24

Now you plug the y in ... giving you the value of angle S to be 24* and angle Q to be 120.

QRS = 36*
Q= 120
