For this case we have the following equation:


y ^ 2 + 7y = 18

Rewriting the equation we have:


y ^ 2 + 7y-18 = 0

Then, we must factor the equation:


We are looking for two numbers that are equal to 7 and multiplied equal to -18.


We have then:


(y + 9) (y-2) = 0

Answer:


An equation that could be used to solve y^2 + 7y = 18 by factoring is:


(y + 9) (y-2) = 0

Please help this is due in 10 minutes!!!!!!

Answer:

Step-by-step explanation:

you just gotta add all the side-lengths together and consider each grid square as 10 instead of 1.

so 70 + 40 + 20 + 60 + 20 + 40 i believe.

this all equals 250.

ask your teacher if its a type, because there's no 250 on there. grab a calculator or something as proof.

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
