what is the slope of the line below
Answer:
m=1/2
Step-by-step explanation:
When finding the slope of a line on a graph, I like to count the steps up/down and to the side between two of the line's points. For this line, we can see that it has points at (2,-1) and (4,0). To get from (2,-1) to (4,0), you need to count
"up 1, over 2"
1/2
Therefore, the slope is 1/2.

Answer:

Step-by-step explanation:
This is a hopeless question. The best anyone can do is guess.
The only one that is completely wrong is C. It says that the more you watch TV the less snacks you eat. Not what the premise says.
D oddly enough could be. You might reach a pinacle and not want anything more. I don't think it is the intended answer, but it is possible.
B is hard to eliminate as well. There might not be any relationship at all or a very weak one. I think it should be eliminated because it most resembles C.
The answer is A. I think this is what you are intended to answer.

Answer:
G = 32
Step-by-step explanation:
To do this problem, we first should rewrite the problem.
g + (-5) =27
Turns into
g - 5 = 27.
Then you can do the problem:
g - 5 = 27

Solve the system of equations.
2.5y + 3x = 27
5x – 2.5y = 5
What equation is the result of adding the two equations?
What is the solution to the system?
Answer:
8x = 32
x = 4
y = 6
Step-by-step explanation:
2.5y + 3x = 27
5x – 2.5y = 5
_____________
8x = 32 (equation obtained after adding the two equations)
x = 32/8
x = 4
Plug x = 4 in 2.5y + 3x = 27
2.5y + 3*4 = 27
2.5y + 12 = 27
2.5y = 27 - 12
2.y5= 15
y = 15/2.5
y = 6
The equation results of adding the two equations is 8x = 32.
The solution to the system is (4, 6).
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, A system of linear equations in variables 'x' and 'y'.
2.5y + 3x = 27...(i) and 5x - 2.5y = 5...(ii)'
Reaaranging eqn(i) we have
3x + 2.5y = 27...(iii)
Adding (ii) and (ii) we have,
8x = 32. (As + 2.5y and - 2.5y cancels)
x = 32/8.
x = 4.
Putting the value of 'x' in eqn(i) we have,
2.5y + 12 = 27.
2.5y = 15.
y = 6.
So, The solution to the system is (4, 6).

The equation of the line in this graph is y = ____x + ____.
Answer:
y=3/2x+3
Step-by-step explanation:
The equation is in y=mx+b format. m is the slope, or steepness of the line, while b is the y intercept (where the line crosses with the y axis).
The given line shows the y intercept; it's 3.
To find the slope, use this equation: y2-y1/x2-x1
Pick any two points and plug them into the equation. For example, use (0,3) (y intercept) and (-2, 0) (x intercept.)
now,
3-0/0-(-2)
3/2
the slope is 3/2.
Now, the line is
y=3/2x+3.
In 56 years, Kevin will be 9 times as old as he is right now.
Answer – 7 years old
SOLVINGS
Let Kevin’s present age be ‘x’
In 56 years, Kevin’s age will be x + 56
In 56 years, Kevin’s age will be 9x
Therefore, x + 56 = 9x
Solving for x
x + 56 = 9x
9x – x = 56
8x = 56
x = 56/8
x = 7
Kevin is 7 years old right now.

Here are some letters and what they represent. All costs are in dollars.
m represents the cost of a main dish.
n represents the number of side dishes.
s represents the cost of a side dish.
t represents the total cost of a meal.
Discuss with a partner: What does each equation mean in this situation? a. a. m = 7.50
b. m = s + 4.50
c . ns = 6
d. m + ns = t
2. Write a new equation that could be true in this situation.
Answer:
t = 3m -n(s+1)
Step-by-step explanation:
Using the information we can describe the value of each letters
using a and b
we have m = 7.50 and m = s + 4.507.50 = s + 4.50
s = 3
substitute s in c, we get
ns = 6n = 6/3 = 2using equation d we have
m + ns = t7.50 + 6 = tt = 13.50so we an equation using the above data
t +ns = 3m - n
t = 3m -n(s+1)

If -3/2 and 5 are solutions, what is the value of a, b, and c? (ax+b)(x+c)=0
Answer:
Step-by-step explanation:
If -3/2 and 5 are solutions to the quadratic equation, hence the expression will give;
(x-(-3/2))(x-5) = 0
(x+3/2)(x-5) = 0
Compare the resulting expression with (ax+b)(x+c)=0, we can see that;
ax = x
divide both sides by x
ax/x = x/x
a = 1
b = 3/2
-5 = +c
c = -5
Hence a = 1, = 3/2 and c = -5

Alexandra has 36 coins valued at $6.00. She has only nickels and quarters. Which equation can be used to solve for the number of nickels, n?
0.05n + 0.25(36 – n) = 6
0.05n + 0.25(36 – n) = 36
n + 0.05 = 0.05n
n + (36 – n) = 36
Answer:
a- 0.05n + 0.25(36 – n) = 6
Step-by-step explanation:
i just did it on edg
The value of each coin (Nickels and Quarters) determines their number in a money sum
The correct option that gives the equation that can be used to solve for the number of nickels, n, is option;
0.05·n + 0.25·(36 - n) = 6
Reason:
The given equation can be presented as follows;
[tex]\begin{array}{|c|c|c|c|}&\mathbf{Number}&\mathbf{Value}&\mathbf{Total \ value}\\&&&\\Nickels&n&0.05&0.05 \cdot n\\Quarters&36 - n&0.25 & 0.25 \cdot(36 - n)\\&&&\\\mathbf{Total}&36&&6\end{array}\right][/tex]
From the above table, we have;
0.05·n + 0.25·(36 - n) = 6
Solving the above equation gives;
0.05·n + 9 - 0.25·n = 6
-0.2·n = 6 - 9 = -3
[tex]n = \dfrac{3}{0.2} = 15[/tex]
Therefore;
The equation that can be used to solve for the number of nickels, n, is; 0.05·n + 0.25·(36 - n) = 6

Joey and Doug hung out at the mall on Saturday. They spent 1-hour shopping for clothes and 1 hour and 30 minutes at the food court. Then they spent 30 minutes at the video arcade before heading home. It was 2:45 P.M. when Joey and Doug left the mall. What time did they start shopping for clothes?
Answer:
They started shopping for cloths at 11:45 AM
Step-by-step explanation:
First of all we have to calculate the whole time that they spent in the mall starting from shopping.
They spent 1 hour on shopping, 1 hour and 30 minutes at food court and 30 minutes in video arcade which makes:
[tex]1 + 1.5+ 0.5 = 3\ hours[/tex]
as 30 minutes is equal to half hour so we used 0.5 in place of it.
Now we know that they left at 02:45 PM. We have to see what time it was 3 hours ago.
[tex]02:45\ PM - 03:00 = 11:45\ AM[/tex]
Hence,
They started shopping for cloths at 11:45 AM
