Step-by-step explanation:
Note how this drawing is symmetrical about a horizontal line drawn halfway between AB and CD and passing through the origin.
Line AB has been subdivided into two equal pieces of length 15, so the length of AB is twice 15, or 30. Due to the symmetry shown, line CD has the same length: 30.

Answers
Answer:
5y + 2y - 4x + 4x = -7 +14
7y = 7
y = 1
2(1) + 4x = 14
4x = 12
x = 3
Step-by-step explanation:
Using the process of elimination
Add both equations. The 4x will be eliminated since one is positive and one is negative. The equation is left with only the y variable and the constant.
When y is found, input it into the second equation to find x.

what is the slope of the blue line and the green line simplified
Answers
Answer:
1
Step-by-step explanation:
The slope can be found using the RISE/RUN equaton.
Looking at both graphs we see that they are parallel so that tells us that they have the same slope.
We can count how many boxes up and then how many boxes right this line goes to find the slope.
We also know that the slope is positive because the lines are increasing from left to right.

7. A scatter plot was created to show the relationship
between the number of staff members and students
at various schools. The scatter plot's trend line has an
equation of y = 0.1x + 18, where y is the total number
of staff members and x is the total number of
students.
Use the equation to predict the number of students in
a school with 120 staff members.
A. 1,038 students
B. 30 students
C. 890 students
D. 1,020 students
Answers
Answer:
1020 students
Step-by-step explanation:
Given the trend line equation :
y = 0.1x + 18,
where y is the total number of staff members and x is the total number of students.
Using the equation, the predicted number of students in a school with 120 staffs ;
y = 120
y = 0.1x + 18
120 = 0.1x + 18
120 - 18 = 0.1x
102 = 0.1x
x = 102 / 0.1
= 1020 students

Answers
Answer:
15) 30°
16) 49.5°
Step-by-step explanation:
15) We solve using the Trigonometric function of Sine
sin θ = Opposite/Hypotenuse
Opposite = 12
Hypotenuse = 24
sinθ = 12/24
θ = arc sin(12/24)
= 30°
Approximately = 30°
16)We solve using the Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
Adjacent = 13
Hypotenuse = 20
cos θ = 13/20
θ = arc cos (13/20)
= 49.458398126°
Approximately = 49.5°

One triangle can drawn with the given information.
What is a triangle?A triangle is a three-sided polygon, which has three vertices. The three sides are connected with each other end to end at a point, which forms the angles of the triangle. The sum of all three angles of the triangle is equal to 180 degrees.
Given that, in ΔNMP, m∠MNP =45°, MN =7.5 feet, and MP=5 feet.
A triangle has six elements – 3 sides and 3 angles. To construct a unique triangle, 3 elements out of six elements are required under a certain combination.
So, with the given elements we can draw a triangle.
Therefore, one triangle can drawn with the given information.
