The x-coordinate of the solution to the system of equations is 3.
What is a system of equations?A system of equations is a set or collection of two or more equations with the same variables. The common solutions are the intersecting points of the equations. The number of equations and unknowns affects the existence and uniqueness of the solution. A system of equations can be classified similarly to single equations.
Given that, the graph given shows a system of equations,
We know that, the solution of the system of equations, is given by the point where the lines intersect,
So, here the lines intersect, at (3, 2)
Therefore, the x-coordinate is 3
Hence, the x-coordinate of the solution to the system of equations is 3.

I already finished it but how do you know if it’s decreasing or increasing?
Please explain to me :)
Answer:
If the slope is positive it is increasing if the slope is negative it is decreasing :)
Example:

If m is positive it is a positive slope
Ms. Sanchez bought 3 pounds of turkey to make sandwiches for her family. She uses 1/3 of a pound for each sandwich. How many sandwiches can she make?
Answer:
the total number of sandwich required is 9
Step-by-step explanation:
The computation of the number of sandwiches made is as follows:
She bought 3 pounds
And one third of pound she required for each sandwhich
So, the total number of sandwich required is
= 3 ÷ 1 ÷ 3
= 3 × 3
= 9
Hence, the total number of sandwich required is 9
The same is to be considered

The following chart shows the number of rows in an auditorium and the total number of seats. What equation defines the number of seats with respect to the number of rows.
a) S=20R+100
b) S=40R+120
c) S=20R+60
d)S=20R
Answer:
Answer: c) S=20R+60
Step-by-step explanation:
Linear Model
The chart supplied shows the number of rows (R) in an auditorium and the total of seats (S).
We'll find the equation that relates them. The equation of a line can be expressed in the slope-intercept form:
S = mR + b
Where m is the slope and b is the intercept.
The slope is found by:
[tex]\displaystyle m=\frac{S_2-S_1}{R_2-R_1}[/tex]
We'll use two sample points (20,460) and (45,960):
[tex]\displaystyle m=\frac{960-460}{45-20}=\frac{500}{25}[/tex]
m = 20
The value of b can be found by using one of the points, for example (20,460), and having m=20:
460 = 20*20 + b
Thus: b = 460 - 400 = 60.
The equation is:
S = 20R + 60
You can test the other points and check they belong to the same line.
Answer: c) S=20R+60
it said in the question how do we solve of the side b

Answer:
Gabriel needs to have $3.75 for sales tax.
Step-by-step explanation:
A sales tax rate of 6.25% means that 6.25 cents is going to be charged for tax for each dollar you spend. (Because 6.25% of $1.00 is 6.25 cents.)
If he was spending $10, the sales tax would be 62.5 cents (6.25 cents per dollar x 10 dollars). Since he is spending $60 on this item, the equation would be (6.25 cents per dollar x 60 dollars) (6.25 cents x 60 = 375 cents).
And 375 cents equals $3.75.

Write an inequality for the graph below
Answer:
y > -1/4x + 4
Step-by-step explanation:
First find the equation of the line itself, which is y = -1/4x + 4, then determine if graph shades above the line or below the line. If it shades above which is true in this case, it will be greater than. If it shades below which does not occur in this case, it will be less than. Because the line is dashed and not solid, it will just be greater than or less than.
Therefore y = -1/4x + 4 → y > -1/4x + 4 [Shades above the line, line is dashed].

How many triangles can I make out of this shape?
Answer:I think it is 84
Step-by-step explanation: 9.3 x 9
Answer:
1,302 triangles
Step-by-step explanation:
All triangles are formed by the intersection of three diagonals at three different points. There are five arrangements of three diagonals to consider. We classify them based on the number of distinct diagonal endpoints. We will directly count the number of triangles with 3, 4, and 5 endpoints. We will then count the number of potential triangles with 6 endpoints, then correct for the false triangles.
You can make 84 triangles with 3 diagonal endpoints, 504 triangles with 4 diagonal endpoints, 630 triangles with 5 diagonal endpoints, and 84 triangles with 6 diagonal endpoints. This adds up to be 1,302 triangles altogether.

Answer:
[tex]x^{2}[/tex] - x - 24 = 0
a = 1
b = 1
c = -24
Step-by-step explanation:
(x + 4)(x - 5) = 4
x(x - 5) = [tex]x^{2}[/tex] - 5x
4(x - 5) = 4x - 20
[tex]x^{2}[/tex] - 5x + 4x - 20 = 4
[tex]x^{2}[/tex] - x - 20 = 4
[tex]x^{2}[/tex] - x - 20 - 4 = 0

You are making a salad. The ratio of olives to croutons is 5 : 3. You put 12 croutons in your salad. How many olives do you put in your salad?
Answer:
20
Step-by-step explanation:
12/3 (the number of croutons) = 4
Since 4 is your base number, you would multiply 4 x 5.
20 olives
Answer:
20
Step-by-step explanation:
Ratio of olives : croutons is 5 : 3.
If you put 12 croutons, you put 4 times the amount of croutons in the ratio since 12/3 = 4.
That means you must also put 4 times the number of olives.
4 * 5 = 20
Answer: 20
