Answer:
A and A- minus that is my best time
Answer:
1. C
2. 3 movies
Step-by-step explanation:
1. the step function is discontinuous at C. multiples of 8 greater than 0,
you can see that at 8, 16, 24 ,32, 40, the graph is discontinuous.
2. when x = 25, y = 3.
Answer:
step 4

good luck]
Step-by-step explanation:
The value of a and b are; 4.8 and 10.8 respectively.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
We have been given a figure which shows that;
Let x, y z, and u lines are parallel.
Therefore, by using proportion we can say that
a/ 12 = 4/ 10
thus, a = 4/ 10 (12)
a =2(12)/ 5
a = 24/5
a = 4.8
Now, 12/b = 10/8
b = 12 (8/10)
b = 6(8)/ 5
b 54/5
b = 10.8
Hence, tha value of a and b are; 4.8 and 10.8 respectively.

Hello,
Let's take a point of d:y=-x+5
if x=0 then y=5 : A=(0,5)
The perpendicular of d passing through A is
y-5=1(x-0) since the slope is -1*?=-1==>?=1
y=x+5
Intersection with the line d':y=-x-9 is
y=x+5 and y=-x-9 ==>x+5=-x-9==>2x=-14==>x=-7 and y=-7+5=-2
B=(-7,-2)
The middle of [AB] is C=((0+(-7))/2,(5+(-2))/2)=(-3.5,1.5)
The line parallele at d passing through C is
y-1.5=-1(x+3.5)==>y=-x-2
