Hey your answer is d I used this app called desmos graphing calculator it’s very helpful for graphs. Hope I helped!!
Step-by-step explanation:
Area of the triangle = (1/2)*base*height
base = x
height = altitude = x+6
Area of the triangle = (1/2)*x*(x+6) = 108
(1/2)*x*(x+6) = 108
x²+6x-216 =0
(x+18)(x-12)=0
x=-18, or x=12
We can use only positive value, so x=12.
Base =12 cm.
x=the number of months
So the "7x" is the $7 per month, and the "10" is the $10 for each CD being ordered. It can't be more than 100, so the "less than or equal to" sign will be used.
Answer:
In the last two sections, we considered very simple inequalities which required one-step to obtain the solution. However, most inequalities require several steps to arrive at the solution. As with solving equations, we must use the order of operations to find the correct solution. In addition remember that when we multiply or divide the inequality by a negative number the direction of the inequality changes.
The general procedure for solving multi-step inequalities is as follows.
Clear parenthesis on both sides of the inequality and collect like terms.
Add or subtract terms so the variable is on one side and the constant is on the other side of the inequality sign.
Multiply and divide by whatever constants are attached to the variable. Remember to change the direction of the inequality if you multiply or divide by a negative number.
