Answer with Step-by-step explanation:
Jackie is selling smoothies at a school fair. She starts the day with $15 in her cash box to provide change to her customers.
Each smoothie costs $3.75, then cost of x smoothies is: $3.75x
Then, y=3.75x+15
When x=0 y=15
when x=4 y=3.75×4+15
i.e. y=30
The only graph which satisfies y=0 at x=0 and y=30 at x=4 is D.
Hence, the correct graph is:
D.

Answer:
43.5 unit^2.
Step-by-step explanation:
Area of the triangle
= 1/2 * base * height
= 1/2 * AB * AC.
AB = √ [(6-1)^2 + (6-8)^2] = √29
AC = √ [(8 - (-7))^2 + (1 - (-5)^2] = √261
So the area = 1/2 * √29 * √261
= 43.5
Your answer would be 29
Why?
Because that is a right angle. They always have to be 90° so 90-61=29
First of all if it is increasing then then it would start at the negative numbers. First is -1.2 second is 1/5 then it is 0.5 and finally 3/5
