Answer:

(6,7) is a solution

Step-by-step explanation:

To determine if (6,7) is a solution, we substitute the point in and see if the inequality is true

15x+11y>12

15(6) + 11(7) >12

90+77 > 12

167>12

This is true so (6,7) is a solution

The point (6,7) means that x = 6 and y = 7 pair up together. Let's plug them into the inequality.

15*x + 11*y > 12

15*6 + 11*7 > 12 ... replace x with 6, y with 7

90 + 77 > 12

167 > 12 ... this inequality is true since 167 is larger than 12

Because the last inequality is true, this means the first inequality is true when (x,y) = (6,7).

Therefore, (6,7) is a solution to the inequality.

I did something wrong could you help?

Answer:

Slope = 1/2

y-intercept = 30

Equation : y = 1/2x + 30

D. 150 miles

Step-by-step explanation:

We can use the two visible points you marked on the graph.

They are (0,30) which is also the y-intercept and (20,40).

Calculate change of y over change of x.

10/20 or 1/2

So the slope is 1/2 and the y-intercept is 30.

Therefore, using y = mx + b form, the equation is y = 1/2x + 30

Then, to find how many miles you drove if the cost was $105, we can plug in 105 for y in the equation.

105 = 1/2x + 30

75 = 1/2x

x = 150

Help!!!!!!!!!!!!!!!!
babymother [125]

Answer:

B

Step-by-step explanation:

To get x by itself, you have to divide each side by the number that x is attached with.

For the first one, divide each side by 3 so that x is by itself and 21/3 is 7 to get x<7

Do the same with the other side but with 5 to get x>11
