A. She mixed up the x- and y-values.
B. She used y-values where she should have used x-values.
C. She did not keep the order of the points the same in the numerator and the denominator.
D. She should have added the values, not subtracted them.
Answers
Answer:
C. She did not keep the order of the points the same in the numerator and the denominator.
Step-by-step explanation:
She needs to switch 1 with 17 so it can be [tex]\frac{17-1}{18-14}[/tex]. It needs to equal [tex]\frac{y2-y1}{x2-x1}[/tex].
Answer:
C. She did not keep the order of the points the same in the numerator and the denominator.
Step-by-step explanation: Hope this helps
The correct slope should look like: 1-17/14-18
If you do 1-17 for the numerator then 14-18 must be the denominator (the slope is 4: -16/-4 = 4)
The equation to find the slope of a line is (y2-y1)/(x2-x1). (x1,y1) is the first coordinate point, (x2, y2) is the other. It does not matter which coordinate point you use first, as long as you remain consistent.

Ann took a taxi home from the airport. The taxi fare was $2.10 point, 10 per mile, and she gave the driver a tip of $5 Ann paid a total of $49.10,
Answers
Answer: 21 miles
Step-by-step explanation:
Here's the remainder of the question:
Write an equation to determine the distance in miles x between the airport and Ann's home.
We are informed that the taxi fare was $2.10 per mile, and she gave the driver a tip of $5 Ann paid a total of $49.10, this can be expressed into an equation as:
(2.10 × x) + 5 = 49.10
2.10x + 5 = 49.10
2.10x = 49.10 - 5
2.10x = 44.10
x = 44.10 / 2.10
x = 21
The distance between the airport and Ann's home is 21 miles.
Joshua went to the grocery store and purchased cans of
soup and frozen dinners. Each can of soup has 200 mg
of sodium and each frozen dinner has 400 mg of sodium.
Joshua purchased a total of 10 cans of soup and frozen
dinners which collectively contain 2400 mg of sodium.
Write a system of equations that could be used to
determine the number of cans of soup purchased and
the number of frozen dinners purchased. Define the
variables that you use to write the system.
Answers
Answer:c + f = 10
200c + 400f = 2400
Step-by-step explanation:
Let's say c is the number of cans of soup and f is the number of frozen dinners.
The total number of items is 10:
c + f = 10
The total amount of sodium is 2400 mg. Each can of soup has 200 mg, and each frozen dinner has 400 mg.
200c + 400f = 2400
The problem doesn't ask you to solve the system, but I'll solve it anyway. We can use substitution or elimination. But first, simplify the second equation by dividing both sides by 200.
c + 2f = 12
Using elimination, subtract the first equation.
f = 2
Plug into either equation to find c:
c = 8
There are 8 cans of soup and 2 frozen dinners.
I need to solve this with substitution and have it in an ordered pair... help!

In which quadrant does θ lie given that sinθ > 0 and cos θ < 0

What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
In the first quadrant, sin, cos and tan are all positive.
In the second quadrant going anti-clockwise, only sin is positive.
In the third quadrant going anti-clockwise, only tan is positive.
In the fourth quadrant going anti-clockwise, only cos is positive
Given data ,
Let the angle be θ
Now , the sin of the angle θ is positive and cos of the angle θ is negative
The equation is given as
sin θ > 0 and cos θ < 0
And , from the trigonometric relations , we know that
In the first quadrant, sin, cos and tan are all positive.
In the second quadrant going anti-clockwise, only sin is positive.
In the third quadrant going anti-clockwise, only tan is positive.
In the fourth quadrant going anti-clockwise, only cos is positive
So , in the second quadrant only sin is positive and all the other trigonometric relations are negative
Therefore , the quadrant where sin θ > 0 and cos θ < 0 will be in the second quadrant
Hence , The quadrant in which the angle θ lies when sin θ > 0 and
cos θ < 0 will be in the second quadrant

Step-by-step explanation:
Using Pythagoras' identity in right triangle KLM to find KM
LM² = KL² + KM²
28² = 16² + KM²
784 = 256 + KM² ( subtract 256 from both sides )
528 = KM² ( take the square root of both sides )
[tex]\sqrt{528}[/tex] = KM
----------------------------------------
Using the sine ratio in right triangle KMN
sin64° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{KN}{KM}[/tex] = [tex]\frac{KN}{\sqrt{528} }[/tex] ( multiply both sides by [tex]\sqrt{528}[/tex]
[tex]\sqrt{528}[/tex] × sin64° = KN , that is

Estimate 72.91 + 67.526 by first rounding each number to the nearest whole number
Answers
Answer:
141
Step-by-step explanation:
First, you would round 72.91 to 73 because the number to the right of 7 is greater than or equal to 5, so you would round up. Same goes for 67.526. round both up to 73 and 68 then add. You would get an answer of 141 :)
Answer: 141
Step-by-step explanation: By rounding up to the nearest whole number, that is taking 72.91 -> 73. The reason it is this way is that when a decimal is past 0.5, you round up. If a decmial is below 0.5, then you round down.
In this specific situation, we get the numbers 72.91 and 67.526.
As I explained, the numbers would round up because both numbers decimal values are above 0.5.
So after 72.91 is 73, and after 67.526 is 68.
68 + 73 =

Answer is 16 because 16/4 = 4 + -12 = -8
Answer:
m=16
Step-by-step explanation:
-8=m/4+(-12)
4=m/4
16=m
so first, you add 12 to the other side to cancel out the -12. 12-8=4. so now you have 4=m/4. to isolate the m, you have to multiply by 4 on both sides, which gives you 16=m or m=16.
