First, we have to solve for x by isolating it on one side.
6x + 10 = -8
(Subtract 10 from both sides)
6x = -18
(Divide both sides by 6)
x = -3
On option C, x is on -3, so that would be the correct answer
There are 3 more dots above the 13 than are above the 12, so the appropriate choice is ...
... A. 3
Answer:
13.5 = 9.5 + x
x=4
Step-by-step explanation:
In this problem, the price of the baseball cap, which is $9.50, and a baseball, whose price is unknown (and therefore must be the variable), total $13.50. So, to set up the equation add the two prices and set them equal to the total, 9.5+x=13.5.
Then, using the subtraction property of equality subtract 9.5 from both sides. This means x=4, so the baseball cost 4 dollars.

The unit cost
Pick any point on the dots of the graph; we have:
The unit cost is then calculated as:
Because the discriminant is less than zero, there are no real solutions in the equation.
