State two ways that you could use a slope of -5/3 to graph a line.
Answer:
rise/run
Step-by-step explanation:
-5 how high/ low you go on y axis
3 how far you move left on the graph
The two ways that could use a slope of -5/3 to graph a line are;
-5 high/ low and go on the y-axis and 3 when moving left on the graph
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The more the slope of the line, the more the line is vertical. When the slope is zero, then the line is horizontal.
To determine the slope, we take the ratio of how much the line's height increases as we go forward or backward on the horizontal axis.
If two lines are given as perpendicular to each other, then their slopes are negative reciprocals of each other. which means, if one line's slope is 'a', then its perpendicular line's slope would be -1/a
A Slope of a straight object is the ratio of how much amount of rise occurs in correspondence to the increment in the run.

If (p, q) is the solution to the system of equations, what is the value of q?
−16p − 2q = 100
p − 4q = 200
Answer:
The solution to the system of equations
p = 0q = -50Hence, the value of q = -50
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}-16p-2q=100\\ p-4q=200\end{bmatrix}[/tex]
solving to determine the value of q
Multiply p − 4q = 200 by 16: [tex]16p-64q=3200[/tex]
[tex]\begin{bmatrix}-16p-2q=100\\ 16p-64q=3200\end{bmatrix}[/tex]
so adding the equations
[tex]16p-64q=3200[/tex]
[tex]+[/tex]
[tex]\underline{-16p-2q=100}[/tex]
[tex]-66q=3300[/tex]
so
[tex]\begin{bmatrix}-16p-2q=100\\ -66q=3300\end{bmatrix}[/tex]
solve -66q = 3300
[tex]-66q=3300[/tex]
Divide both sides by -66
[tex]\frac{-66q}{-66}=\frac{3300}{-66}[/tex]
[tex]q=-50[/tex]
substituting q = -50 in −16p − 2q = 100
[tex]-16p-2\left(-50\right)=100[/tex]
[tex]-16p+100=100[/tex]
Subtract 100 from both sides
[tex]-16p+100-100=100-100[/tex]
Simplify
[tex]-16p=0[/tex]
Divide both sides by -16
[tex]\frac{-16p}{-16}=\frac{0}{-16}[/tex]
[tex]p=0[/tex]
Thus, the solution to the system of equations
p = 0q = -50Hence, the value of q = -50
- Lynn has two cats, Polly and Barney.
Lynn knows that Polly has a mass of 3 kg.
She estimates that Barney's mass is 3 times Polly's mass.
Work out an estimate of Barney's mass.
Answer:
9kg
Step-by-step explanation:
Because it is said that Polly's mass is 3kg but, Barney's mass is 3 times more kg than Polly.
So we multiply 3 (Polly's mass) multiplied by 3(cuz it is said three times more). So 3*3 = 9kg

assume that the class has 80 students and that the examination period is 95 minutes in length. How many students do you expect will be unable to complete the exam in the allotted time
Answer:
Number of students successful= 75
Number of students not able to complete the exam in the allotted time= 5
Step-by-step explanation:
In this question the main part is missing .The given statement is the sub part of the problem .
Suppose the main part is
The time needed to complete a final examination in a particular college course is normally distributed with a mean of 80 minutes and a standard deviation of 10 minutes.
If the main part was given like this only then we could do the following calculations.
So from above the
Population mean = μ= 80
Population Standard deviation =σ= 10 mins
Sample mean = x`= 95
Sample size= n= 80
Now first we calculate the z= score
z= x`-μ/σ
z= 95-80/10= 1.5
From the z- table we find the P (z< 1.5)= 0.9332
Now we have to find the number of students who need to complete the exam in the allotted time
Number of students successful= np= 80 * 0.9332= 74.656= 75
Number of students not able to complete the exam in the allotted time= 80-75= 5
These answers are based on the main part supposed to be as added just to explain how it will be calculated.

(4+g)(-11)=121 pls show work whoever has answers first with right answer gets brainliest
Answer:
g = -15
Step-by-step explanation:
First, you are going to want to divide by -11 on both sides of the equation.
— (4 + g) (-11) / -11 = 121 / -11
— 4 + g = -11
(Note: dividing a positive number by a negative number will result in a negative number.)
Next, subtract 4 from both sides of the equation.
— 4 + g - 4 = -11 - 4
— g = -15
So, assuming you are looking for the value of g, you're answer is g = -15

Step-by-step explanation:
We list the numbers from least to greatest
19, 23, 30, 33, 34, 40, 49, 50, 59, 67
The current median is 37
if you add 58, it would be
19, 23, 30, 33, 34, 40, 49, 50, 58, 59, 67
so the median changes to 40
40-37=3

Given m \| nm∥n, find the value of x.
Answer:
x=32
Step-by-step explanation:
If you do 2x-16+4x+4=180, then you should get 32.
The value of x is 32.
Given,
The m line is parallel with the n line.
We need to find the value of x.
What are the relationships between parallel lines and angles?If two lines are parallel the corresponding angles are congruent.
Example:
D /

A<----------------F/----------------------->B
/
C <-----------M/------------------------------>D
/
E /
AFD = CMF
AFM = CME
From the figure, we see that
2x - 16 + 4x + 4 = 180
6x - 12 = 180
6x = 180 + 12
6x = 192
x = 192/6
x = 32
Thus the value of x is 32.

The linear scale factor of two similar solids is given. Then the surface area and volume of the smaller figure are also given. Find the surface area and volume of the large figure.
Scale factor: 5:8
Surface area: 475
volume: 1125
Surface area: ?
volume: ?
Answer:
Surface area: 1216
Volume: 4608
Step-by-step explanation:
Scale factor: 5:8
This means that the dimensions of the larger figure are 8/5 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(8/5) by the original surface area(475). So
[tex]S = (\frac{8}{5})^2 \times 475 = \frac{64}{25} \times 475 = 64 \times 19 = 1216[/tex]
Volume:
The volume is found multiplying the cube of the change(8/5) by the original volume(1125). So
[tex]S = (\frac{8}{5})^3 \times 1125 = \frac{512}{125} \times 1125 = 512 \times 9 = 4608[/tex]
