Answer:
C, D (-4) ⇒ E, G (0) ⇒ H (1) ⇒ A, F (3) ⇒ B(8)Step-by-step explanation:
The y-intercept is the coordinate of y at x = 0.
Let's find them all and then order.
A)
a(0) = -2*0 + 3 = 3B)
b(0) = 8 as per graphC)

Answer:
x and y = 5√2.
Step-by-step explanation:
This is a 45:45:90 triangle so length of x = length of y.
In this triangle the ratio of the sides is 1:1:√2
Finding length of x and y:
1/√2 = x/10
√2x = 10
x = 10/√2
= 10√2/2
= 5√2.

Scores on a statewide standardized test are normally distributed with a mean of 12.89 and a standard deviation of 1.95. Certificates are given to students whose scores are in the top 2% of those who took the test. This means that they scored better than 98% of the other test takers. Marcus received his score of 13.7 on the exam and is wondering why he didn’t receive a certificate. Show all work to determine whether Marcus’ score was high enough to earn a certificate. Write a letter to Marcus explaining whether or not he will be receiving a certificate. Include a brief summary of your statistical analysis in your letter.
Answers
Answer:
Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.

Which graph represents a function? On a coordinate plane, a line with 2 angles crosses the x-axis at (negative .5, 0), the y-axis at (0, 1), turns at (1, 3), crosses the x-axis at (1, 0), turns at (1, negative 2), and crosses the x-axis at (2, 0). On a coordinate plane, a curved line crosses the y-axis at (0, 1.5), the x-axis at (negative 2, 0), and the y-axis at (0, negative 1.5). On a coordinate plane, a line enters the plane at point (negative 5, 4), makes a 90-degree turn at (negative 1, 0), and leaves the plane at point (negative 5, negative 4). On a coordinate plane, a line with an s curve enters the plane at point (negative 3.75, 5), crosses the x-axis at (negative .75, 0), the y-axis at (0, 0), leaves x-axis at (.75, 0), and exits the plane at point (3.75, negative 5).

Short Explanation
The absolute value is the distance between a number and zero. The distance between -4 and 0 is 4 so the result of |-4| is 4

The absolute value or modulus of a real number, denoted, is the non-negative value of without regard to its sign. Namely, if is positive, and if is negative, and. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.
Leah needs to order some new supplies for the restaurant where she works. The restaurant needs at least 748 knives. There are currently 214 knives. If each set on sale contains 12 knives, write and solve an inequality which can be used to determine ss, the number of sets of knives Leah could buy for the restaurant to have enough knives.
Answers
Answer: s (greater than or equal to) 44.5
Step-by-step explanation:
current # of knives = 214
knives per set = 12
knives needed = 748
# of sets = s
knives per set x (times) # of sets + current # of knives (greater than or equal to) knives needed
12s + 214 (greater than or equal to) 748
SOLVE:
12s + 214 (greater than or equal to) 748
-214 -214
12s (greater than or equal to) 534 you need to divide both sides by 12
s (greater than or equal to) 44.5

Applying the 45-45-90 Theorem, Find the lengths of the other two sides of a right triangle if the length of the hypotenuse is 4√2 inches and one of the angles is 45°.
Answers
Rule: If x is the leg of a 45-45-90 triangle, then x*sqrt(2) is the hypotenuse.
We can prove this by showing that x^2+x^2 = (x*sqrt(2))^2 is an identity. It's from the pythagorean theorem a^2+b^2 = c^2.
Put another way, if we know that a = x and b = x are the two congruent legs, then x^2+x^2 = c^2 leads to c = x*sqrt(2). This triangle is known as an isosceles right triangle.
So if 4*sqrt(2) is the hypotenuse, we match that up with the template x*sqrt(2) and see that x = 4 must be the case.
