If you rewrite the second one to be the y=mx+b form then you get
8x-14= -2y
Divide by -2 and get
-4x+7=y
Because the slopes are the same the lines will never intersect which means there is no solution

Answer:
y = -2x + 12
Step-by-step explanation:
Step 1: find the slope
y = 1/2x + 5
The equation of the line is
y = mx + c
m - slope
m = 1/2
Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other
m = -2
Step 2 : using a point slope form
y - y1 = m( x - x1)
( 2 , 5)
x1 = 2
y1 = 5
y - 2 = -2( x - 5)
y - 2 = -2x + 10
y = -2x + 10 + 2
y = -2x + 12
The equation of the line is
y = -2x + 12

A board is 48 in long. It must be divided into 4 pieces of equal length, and each cut will cause a waste of 3/16 in. How long will each piece be after the cuts are made?
Answer:
12 pieces
Step-by-step explanation:
Total length of the board = 48 in
It must be divided into 4 pieces of equal length
This means, there will be 3 cut to have 4 pieces
Each cut will cause a waste of 3/16 in.
Total waste = 3 cut × 3/16 in
= (3*3)/16
= 9/16 in
Length of board remaining = Total length of the board - Total waste
= 48 - 9/16
= (768-9)/16
= 759/16 in
How long will each piece be after the cuts are made?
Length of each piece after the cut = Length of board remaining / 4
= 759/16 ÷ 4
= 759/16 × 1/4
= 759/64
= 11.859375
Approximately 12 pieces to the nearest whole number

The seventh grade class is putting on a talent show to raise money for a class trip. It costs $500 to rent the banquet hall they are planning on using. If they charge $15 per ticket, how many tickets do they need to sell in order to raise at least $1000? Part A The variable in this problem will represent the number of Part B Choose the correct inequality to represent the story problem
Answer:
Part A; 15x
Step-by-step explanation:
Part A; 15(67)
= $1005
Part B; ??
The number of tickets to be sold if, The cost of the banquet hall is $500, The cost per ticket is $15, the Total money to be raised is $1000, is 67, and the equation is given by 1000 = 15x.
What is the equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.
In other terms, it is a mathematical statement stating that "this is equivalent to that."
Given:
The cost of the banquet hall = $500,
The cost per ticket = $15,
Total money to be raised = $1000
Write the equation of the number of tickets as shown below,
1000 = 15x
Here, x is the number of tickets,
x = 1000 / 15
x = 66.67 or 67

If the arrow is pointing to the right (----->) Then it is Greater-than which is >.
Since the arrow is pointing right the answer will be x>-3 which is D

a. Is the relationship between number of towers and number of customers proportional? Explain. Choose the correct answer below and, if necessary, fill in the answer box to complete your choice.
A.
Yes. The ratios of towers to customers (thousands) are all equivalent to a unit rate of nothing.
B.
No. The ratios of towers to customers are not all equivalent.
Answer:
A.
Step-by-step explanation:
Divide 169 by 3.25 and you get 52.
Divide 221 by 4.25 and you get 52.
Do this for all of the rest, and they will all be 52.
Hope this helps!
Yes. The ratios of towers to customers (thousands) are all equivalent to a unit rate of nothing. Therefore, option A is the correct answer.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent.
The given table is
Cell Phone Towers Customers (thousands) Towers
3.25 169
4.25 221
5.25 273
7.25 377
Here, the ratio of Cell Phone Towers : Customers (thousands) Towers
3.25 : 169
= 325/16900
= (325÷325)/(16900÷325)
= 1/52
4.25 : 221
= 425/22100
= 1/52
5.25 : 273
= 525/27300
= 1/52
7.25 : 377
= 725/37700
= 1/52
Therefore, the ratio of given cell phone towers to customers (thousands) towers are equivalent.

Answer:
y=1, x=2
Step-by-step explanation:
so first solve for y. plus x=3y-1 into the other equation.
so 3(3y-1)+4y=10.
Simplify
9y-3+4y=10 Add 3 to both sides
9y+4y=13 Add
13y=13 . Divide 13 from both sides
y=1

The exterior angles of a quadrilateral have measures of 72 degrees, 58degrees, 2x degrees, and 3x degrees. Find the value of x.
Answer: x = 46
Step-by-step explanation: The theorem is:
The sum of all exterior angles of a polygon is 360
Here, our polygon is a "quadrilateral" -- 4 sided figure
We can say that the sum of all 4 exterior angles is 360. We set up an equation and solve for x. Shown below:

find the value of x in the triangle below
Answer:
87 degrees
Step-by-step explanation:
the three angles of a triangle add up to one hundred eighty degrees.
1. Add the degrees of the known angles together
56 + 37 = 93
2. Since a triangle adds up to one hundred eighty degrees, you would subtract your known degrees from the total
180 - 93 = 87
