Find the slope of the line that contains the following points: (17, -12) and (17, 8) *
Answers
Answer:
20/0 = 0
Step-by-step explanation:
The slope of the line that passes through (17, -12) and (17, 8) is undefined.
The equation of a line is a vertical line where it intercepts at 17 on the x-axis.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Two points:
(17, -12) and (17, 8)
The slope of a line that passes through two points (a, b) and (c, d) is given as:
Slope = (d - b) / (c - a)
The slope of the line that passes through (17, -12) and (17, 8).
Slope = (8 - (-12)) / 17 - 17
Slope = 20/0
Slope = undefined
Since the slope is undefined the equation of a line is a vertical line where it intercepts at 17 on the x-axis.
Thus,
The slope of the line that passes through (17, -12) and (17, 8) is undefined.
The equation of a line is a vertical line where it intercepts at 17 on the x-axis.

"All functions are relations but all relations are not functions."
Functions are the relation that classifies the set of outputs to the set of inputs. Moreover relation is identified as the group of ordered pairs.
A relation is a way of expressing a connection or relationship between any two pieces of information.

In ATUV, TV is extended through point V to point W,
m VTU (x - 2)°, mZTUV (2x + 11)', and
mZUVW = (6x – 15)°. Find mZUVW.
Answers
Answer:
m∠UVW = 53°
Step-by-step explanation:
From the picture attached,
m(∠VTU) = (x - 2)°
m(∠TUV) = (2x + 11)°
m(∠UVW) = (6x - 15)°
Since, ∠UVW is the exterior angle of the ΔTUV,
By the triangle sum theorem,
m∠VTU + m(∠TUV) + m(∠UVW) = 180°
(x - 2)° + (2x + 11)° + (6x - 15)° = 180°
9x - 6 = 180
9x = 186
x = [tex]\frac{186}{9}[/tex]
x = [tex]\frac{62}{3}[/tex]
By the property of exterior angle of a triangle,
m(∠UVW) = m(∠VTU) + m(TUV)
= (x - 2) + (2x + 11)
= 3x - 9
Now by substituting the value of x,
(3x - 9)° = [tex]3(\frac{62}{3})-9[/tex]
= 62 - 9
= 53°
Therefore, m∠UVW = 53°

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The following coordinates are from the graph.
(2, 4), (4, 8), (8, 16).
The x-coordinates denote the number of candles.
The y-coordinate denotes the cost.
Now,
(2, 4) means 2 candles cost $4.
(4, 8) means 4 candles cost $8.
(8, 16) means 8 candles cost $16.
The ratio of candles to dollars.
= 2/4
= 1/2
This means,
The cost of one candle is $2.
Thus,
The cost of one candle is $2.

Noel bought a printer for $10 less than half its original price. If noel paid $88 for the printer, what was the original price?
Answers
Answer:
$196
Step-by-step explanation:
Step one
given data
We are told that Noel bought a printer for $10 less than half its original price
let the original price be x
hence Noel paid = x/2-10= 88
Step two
amount paid= x/2-10= 88
Collect like terms
x/2= 88+10
x/2= 98
cross multiply
x=196
Hence the original price is $196
Soro bought a $50.00 bus card at the beginning of the week. Each bus ride costs $2.50. He needs to have at least $20.00 on his card at the end of this month.To determine how many bus rides he can take between now and the end of this month, Soro wrote and solved the following inequality:
50 minus 2.5 x greater-than-or-equal-to 20. Negative 2.5 x greater-than-or-equal-to negative 30. x greater-than-or-equal-to 12.
What error, if any, did Soro make when writing or solving this inequality?
Soro’s original inequality should have been 50 minus 2.5 x less-than-or-equal-to 20 .
Soro should have added 2.5 to each side for his first step.
Soro should have reversed the inequality symbol when using the division property of inequality.
Soro’s work shows no errors.
