Answer:
203 square inches.
Step-by-step explanation:
First you have to find the area of the triangles, and you do so by using the formula A = (B·H)/2, where the a represents area, b represents base, and h represents height. Assuming all of the triangles are the same, you multiply 7 by 11 and then divide by 2 (which equals 38.5) and then multiply that by 4 (which equals 154) and then you have the area of all four triangles combined. Then to find the area of the cube you simply square 7, which results in 49, and then add that to the area of the triangles, which leaves you at 203. 203 square inches is your answer.
Answer:
D. y = 2x² + 1
E. y = x²
Step-by-step explanation:
Linear function:
A linear function has the following format:

In which a is the slope and b is the y-intercept. A constant function is linear, as it is the special case in which a = 0.
In this question:
In options D and E, the highest exponent of x is 2, which means that they are not linear functions, and so these options are the answer.
Answer:
Step-by-step explanation:
At the self employed store, her monthly expense would be
y = $835
Which would plot as a horizontal line
At the franchise store here expense would be
y = 5x where x is the number of haircuts completed.
This would plot as a straight line of slope 5
The two would intersect when the two y values are equal
5 x = 835
so the same cost per month would occur at y = 835
at the franchise, she would have completed 835/5 = 167 haircuts.
If she plans on doing fewer than 167 haircuts per month, she nets more money at the franchise,
If she completes more than 167 haircuts per month, the self employed store deal keeps more money in her pocket.
