Answer: C. 3n + 3 = 198
3 times Monday plus 3
3 times the number they sold Monday represents 3n.
3 more represents +3.
198 is just the total.
Hope this helps :)
The answer is C. 5x
We need to find the price of one magazine. To do this we divide 350 by 70
350 / 70 = $5 per magazine

Answer: Second option.
Step-by-step explanation:
The Slope-Intercept form of the equation of the line is:
Where "m" is the slope of the line and "b" is the y-intercept.
You know that the second equation of the System of equations given in the exercise is:
Then, you need to solve for the variable "y" in order to write it in Slope-Intercept form. The steps are:
1. Apply the Distributive property and simplify:
2. Now subtract 6 from both sides of the equation:
3. Subtract 
from both sides of the equation:
4. Subtract 
from both sides:
5. Divide both sides by -2:
Answer:
Result at time x = 4 seconds the soccer ball hit the ground.
Step-by-step explanation:
At the moment just before the ball is kicked, it is on the ground and so the height f(x) is zero meters. After the kick, the ball goes through the air and it's path can be described by a (mountain) parabola.
So lets see after how many second (x) the height = 0 once again.
f(x) = 8x-2x^2
f(x) = 0
8x - 2x^2 = 0
Try to write the formula in two terms
-2x * (x - 4) = 0
When a product of two or more terms equals zero, then at least one of the terms must be zero.
Now solve each term = 0 separately, meaning, solve as many equations as there are terms in the product.
Any solution of term = 0 solves product = 0.
Solve the first term:
-2x = 0
Multiply left an right from the = singn with the factor -1 gives this outcome:
2x = 0
x = 0
Solve the second term:
x-4 = 0
x = 4
Result at time x = 4 seconds the soccer ball hit the ground.
x = 4
x = 0
