A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .
A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .
If a line is horizontal the slope is zero. This is a constant function.
If a line is vertical the slope is undefined (see below).

At lunch, Marc bought 2 quesadillas and 2 tacos for $10.16, and Jason paid $11.84 for 5 tacos and 1 quesadilla. What was the cost of each taco and quesadilla? Let the cost of a quesadilla be x and the cost of a taco be y.
Answers
Answer:
X = 3.39 (Quesadilla) Y= 1.69 (Tacos)
Step-by-step explanation:
You need to do systems of equations.
You take the quesadillas which is X and the Taco is Y and plug them into the equation with the total like this:
2x + 2y = $10.16
x + 5y = $11.84
solve and you get
(3.39, 1.69)
Answer: X = 3.39 (Quesadilla) Y= 1.69 (Tacos)

What is the percent increase from 50 to 69
Answers
A change from 50 to 69 represents a positive change (increase) of 38%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old
|Old|
× 100%
Percent change = 69 - 50
|50|
× 100% =
19
50
× 100 = 38% (increase)
Where: 50 is the old value and 69 is the new value. In this case we have a positive change (increase) of 38 percent because the new value is greater than the old value.
First find the difference between 69 and 50.
69 - 50 = 19
Now to find the decimal, divide 19 by 50 which would equal 0.38. And to find the percentage, move the decimal two spaces to the right.
Answer: 38%

The bill for a group of eight people at a restaurant was $125 before the tip was added. The group wants to add an 18% tip and split the bill evenly. How much will each member of the group pay
Answers
Answer:
$18.43
Step-by-step explanation:
The computation of each member have to pay as follows:
The bill before the tip is $125
The tip percentage is 18%
So the bill after tip is
= $125 + $125 × 18%
= $125 + $22.5
= $147.50
Now for each member, it would be
= $147.50 ÷ 8 members
= $18.43

What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
A store sells memory cards for $25 each. Then the cost price of each memory card is given as,
⇒ $25 / 1.25
⇒ $20
The amount that the store pays for 50 memory cards will be given as,
⇒ $20 x 50
⇒ $1,000
The amount that the store pays for 50 memory cards will be $1,000.

In the laundry basket there are 4 black socks, 7 pink socks, and 10 white socks. Allison will randomly select 2 socks from the basket one at a time without replacement. What is the probability that Allison will select 2 pink socks?
Answers
Answer: [tex]\dfrac{1}{10}[/tex]
Step-by-step explanation:
Given: In basket, we have
4 black socks, 7 pink socks, and 10 white socks.
Total socks = 4+7+10 = 21
Probability that first sock is pink = [tex]\dfrac{\text{Number of pinks socks}}{\text{Total}}=\dfrac{7}{21}=\dfrac13[/tex]
Now basket has 6 pink socks left and total socks left= 20
Probability that second sock is pink =[tex]\dfrac{6}{20}=\dfrac{3}{10}[/tex]
The probability that Allison will select 2 pink socks = [tex]\dfrac13\times\dfrac{3}{10}=\dfrac{1}{10}[/tex]
Hence, the probability that Allison will select 2 pink socks = [tex]\dfrac{1}{10}[/tex]

Step-by-step explanation:
178-149
Answer:
m∠ TUJ = 29°
Step-by-step explanation:
Although this question looks hard, it really is not.
Since we know that TUV = 178° and we know that JUV = 149° we can easily figure out TUJ.
First, since we know that the total is 178° (TUV) we can subtract angle JUV from TUV to get TUJ
178° - 149° = ?
178° - 149° = 29°
