Answers

Answer:

The correct answer is D

Step-by-step explanation:

The  graph of inequality y ≤ -2x is option D .

What is inequality?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

According to the question

y ≤ -2x  

The graph of inequality  

at x = -2

y≤ 4

at x = 3

y ≤ -2*3

y ≤ -6  

Hence, the  graph of inequality y ≤ -2x is option D .

2. Y - 3 = X + 2
2X - 1 = Y
Show your work

Answers

Y - 3 = X + 2 ...............….... (1)
2X - 1 = Y ........................... (2)

From (2),
2X - 1 = Y

Y = 2X - 1


Sub (2) into (1),
(2X-1) - 3 = X + 2

2X - 1 - 3 = X + 2

2X - X = 2 + 1 + 3

X = 6


Sub x=6 into (1),
Y = 2(6) - 1

Y = 12 - 1

Y = 11

What is the equation of the line that passes through the point (-5,5) and has a
slope of -1?

Answers

Answer:

y = - x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 1 , then

y = - x + c ← is the partial equation

To find c substitute (- 5, 5 ) into the partial equation

5 = 5 + c ⇒ c = 5 - 5 = 0

y = - x ← equation of line

Answer:

Step-by-step explanation:

The polygon has 6 sides.

Sum if interior angles = (n-2)180

=(6-2)180

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 3672 no votes what was the total number of votes

Answers

Answer: 10,098 votes

Step-by-step explanation:

The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.

To find the total votes, add the ratios:

= 7 + 4

= 11

4/11 are the no votes out of the total. Assuming the total is x, the formula is:

4/11x = 3,672

x = 3,672 / 4/11

x = 10,098 votes
