Answer:
17.
9x - 2 = 8x + 6 (opposite angles on the transversal)
9x - 8x = 6+2
x = 8
18.
-5 + 21x + 15x +5 = 180 (angles on the same side of transversal add up to 180)
36x = 180
x = 180/36
x = 5
19.
9x + 4 + 95 = 180 (angles on the same side of transversal add up to 180)
9x + 99 = 180
9x = 180-99
9x = 81
x = 81/9
x = 9
20.
16x - 2 = 110 (opposite angles on the transversal)
16x = 110 +2
16x = 112
x = 112/16
x = 7
21.
29x + 4 = 31x -4 (opposite angles on the transversal)
4 + 4 = 31x - 29x
2x = 8
x = 8/2
x = 4
22.
12x + 2 + 6x + 16 = 180(angles on the same side of transversal add up to 180)
18x +18 = 180
18x = 180-18
18x = 162
x = 162/18
x = 9

What is the slope of the line that passes through the points (5, 4) and (13.25, -18) ?
A.) 83/3
B) 3/8
C) −3/8
D) 8/3
Answers
Answer:
Answer: D. 8/3
Step-by-step explanation:
Formular for slope:
[ consider points (x1, y1) and (x2, y2) ]
[tex]slope = \frac{y_{2} - y _{1} }{x _{2} - x _{1} } \\ [/tex]
x1 » 5, y1 » 4
x2 » 13.25, y2 » -18
[tex]sloe = \frac{ - 18 - 4}{13.25 - 5} \\ \\ = \frac{22}{8.25} \\ \\ { \boxed{ \boxed{slope \: = \frac{8}{3} }}}[/tex]

The indoor climbing gym is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 12 buses with 504 students. High School B rented and filled 2 vans and 4 buses with 184 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.
Answers
High school A: 3 vans + 12 buses = 504 students
High school B: 2 vans + 4 buses = 184 students
Multiply High school B by 1.5:
High school B: 3 vans + 6 buses = 276 students
Subtract High school B from High School A:
6 buses = 228 students
Divide students by buses:
Buses = 228 / 6 = 38 students per bus
Now solve for vans using high school A:
3 vans + 12(38 students per bus) = 504 students
Simplify:
3 vans + 456 students in buses = 504 students
Subtract students in buses from both sides:
3 vans = 48
Divide both sides by 3:
Vans = 16
Answer: vans = 16 students, buses = 38 students
Which inequality represents all values of x for which the quotient below is
defined?
28(x-1) = 8x?
O A. x less than or equal to -1
B.x great than or equal to 1
O C. x> 1
O D. x<-1
Answers
You can re-write this quotient this way :
[tex]\frac{\sqrt{28(x-1)}}{\sqrt{8x^{2} }} = \sqrt{ \frac{28(x-1)}{8x^{2} } }\\[/tex]
What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))
In other word we must find x so that :
[tex]\frac{28(x-1)}{8x^{2}}\geq 0[/tex]
at the end we get
28(x-1) ≥ 0
28x - 28 ≥ 0
28x ≥ 28
x ≥ 1
So the answer is B, x ≥ 1

A phone company offers two monthly plans. Plan A costs $40 plus an additional $0.05 for each minute of calls. Plan B has no initial fee but costs $0.25 for each minute of calls. What is the cost when the two plans cost the same for a set number of minutes?
Answers
Answer:
20 minutes
Step-by-step explanation:
Plan A
C = 40 + 0.05m
Plan B
C = 0.25m
we want to find the number of minutes m such that the two plan cost the same.
Hence
40 + 0.05m = 0.25m
40 = 0.20 m
m = 40/ 0.20
m = 400 / 2
m = 20 minutes.
