Answer:
D. rectangle
Step-by-step explanation:
The slopes of 2 lines are perpendicular when they are the negative reciprocal of each other. In this case, that is true, because 3 is the negative reciprocal of -1/3 and vice versa. This means it's either a rectangle or a square.
The lengths of the lines are not all the same, meaning it cannot be a square.
Therefore, the best name for the quadrilateral MATH is rectangle.

10s - 5 = 20
Value of s
Answer:
2.5
Step-by-step explanation:
10s-5=20
(add 5 to both sides)
10s=25
(divide both sides by 10)
s=2.5
Answer:
s = 2.5
Step-by-step explanation:
you need to figure out what multiplied by 10 will give you 25, because then you have to subtract 5 in the second part of the equation to get 20.
10 multiplied by 2.5 equals 25, so s = 2.5

A relation is (1 point)
the output (y) values of the relation
the input (x) values of the relation
a set of points that pair input values with output values
x and y values written in the form (x, y)
Answer:
a set of points that pair input values with output values
Step-by-step explanation:
The set of points that relate, input values with output values.
A relation is a set of points that pair input values with output values.
Therefore the correct option is C.
In mathematics, a relation is a set of ordered pairs, where each pair consists of an input value (x) and an output value (y) that are related to each other in some way.
These ordered pairs represent the relationship between the input and output values of the relation.
So, a relation can be represented as a set of points in the coordinate plane, where each point represents an ordered pair (x, y). The relation itself is not specifically the input (x) values or the output (y) values, but rather the collection of all the paired values.
Therefore the correct option is C.

Jenna works in an ice cream shop. When she starts her shift the tub of chocolate ice cream is 2/3 full. When she finishes her shift 6 1/2 h later, there is only 1/6 of the tub left. What was the average hourly change in tub fullness?
IMMEDIATE PLEASE.
Answer:
[tex]-1/13\text{ tub per hour}[/tex]
Step-by-step explanation:
First, let's find how much of the tub was used within the time.
We know that the tub was 2/3 full was Jenna started.
And it was only 1/6 full when Jenna ended.
Therefore, to find the amount used, we can subtract 1/6 from 2/3. So:
[tex]u=\frac{2}{3}-\frac{1}{6}[/tex]
Make a common denominator. Change 2/3 to 4/6 by multiplying both layers by 2. So:
[tex]u=\frac{4}{6}-\frac{1}{6}[/tex]
Subtract and reduce:
[tex]u=\frac{3}{6}=\frac{1}{2}[/tex]
Therefore, 1/2 of the tub was used after 6 1/2 hours.
To find the average hourly change, we will put the amount used over the amount of hours. 6 and 1/2 hours is the same as 13/2 hours. Therefore, the hourly change will be:
[tex]c=\frac{\frac{1}{2}}{\frac{13}{2}}[/tex]
Remember when dividing fractions, we:
1) Flip the divisor (the second number).
2) Change the division sign to a multiplication sign.
3) Multiply.
So:
[tex]c=\frac{1}{2}\div\frac{13}{2}\\\Rightarrow c=\frac{1}{2}\times \frac{2}{13}[/tex]
Multiply straight across and reduce:
[tex]c=\frac{2}{26}=\frac{1}{13}[/tex]
However, since we are using up the tub, our rate will be negative. Therefore:
[tex]c=-\frac{1}{13}[/tex]
Therefore, the average hourly rate was -1/13 tub per hour.
This means that after each hour, 1/13 of the tub will be used up.
Edit: Corrected Wrong Answer
Answer: -1/13 of a tub per hour
Step 1: Subtract.
2/3 - 1/6 = ?
Step 2: Find the common denominator.
4/6 - 1/6 = 3/6.
Step 3: Simplify the fraction.
3/6 = 1/2
Step 4: Put 1/2 over 13/2.
1/2 over 13/2
Step 5: Flip divisor around. Then divide.
1/2 ÷ 13/2
Step 6: Multiply.
1/2 × 2/13 = 2/26.
2/26 reduced = 1/13.
Since it was used, now it is -1/13
Answer = -1/13 of a tub per hour

Write the standard form of the equation y-3=-2/3(x+5)
Answer:
In linear standard form, 10x-15y=29
Step-by-step explanation:
The solution is y = ( -2/3 )x - 1/3
The standard form of the equation y-3=-2/3(x+5) is given by the equation A
where y = ( -2/3 )x - 1/3
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
So , the standard form of the equation of line is given by equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
Now ,
y - 3 = -2 / 3 ( x + 5 )
Multiply by 3 on both sides of the equation , we get
3y - 9 = -2 ( x + 5 )
On simplifying the equation , we get
3y - 9 = -2x - 10
Adding 9 on both sides of the equation , we get
3y = -2x - 1
Divide by 3 on both sides of the equation , we get
y = ( -2/3 )x - 1/3
The equation of line is y = ( -2/3 )x - 1/3 where the slope of the line is -2/3 and the y intercept of line is -1/3
Hence , The standard form of the equation y-3=-2/3(x+5) is given by the equation A where y = ( -2/3 )x - 1/3

What is an equation in point slope form of the line that passes through (7, 1) and (-3,9)
Answer:
y= -4/5x+33/5
Step-by-step explanation:
for questions like these, the slope is always defined as the change in y over the change in x or use the equation m=y2-y1/x2-x1.
x1=7 and y1=1
x2=-3 and y2=9
now plug these numbers in to the equation. m= 9-1 / -3-7 Or m= 8/-10 simplified to m= -4/5
now that we have the slope you can plug it in to the equation y=mx+b and get y= -4/5 + b.
to find b, the y-intercept, you can use either of the two points and the answer will be the same. for this one, I'll use (7,1).
1= -4/5 x 7+b. b= 33/5
