Solve system of equation algebraically
y = 2x - 3
x + y = 18

Answers

Answer:

x = 7

y = 11

Step-by-step explanation:

Given the system;

y = 2x - 3

x + y = 18

1. Approach

The easiest way to solve this system of equations is to solve the second equation for the variable (y). Then add the systems, use algebra to solve for the value of (x), then substitute that value back into one of the original equations to solve for the value of (y). Another name for the method in use is the method of elimination, this is when a [erspm manipulates one of the equations in a system of the equation such that when they add the equations, one of the variables eliminatates. Thus, they can solve for the other variable and the backsolve for the value of the unknown variable.

2. Solve one of the equations for a variable

Manipulate the system such that each equation is solved for the same variable,

x + y = 18

Inverse operations,

x + y = 18

-18        -18

x + y - 18 = 0

   -y         -y

x - 18 = -y

3. Use elimination

Now substitute this back into the original system,

y = 2x - 3

-y = x - 18

Add the systems,

y = 2x - 3

-y = x - 18

_________

0 = 3x - 21

Inverse operations,

0 = 3x - 21

+21       +21

21 = 3x

/3    /3

7 = x

4. Find the value of the unknown variable

Backsovle to find the value of (y),

x + y = 18

Substitute,

7 + y = 18

Inverse operations,

7 + y = 18

-7        -7

y = 11

Answer:

X=3 Y=15

Step-by-step explanation: First you need to use the problem 18/2=x to find the value of x. Now to find the value of y, you need to subtract 3 from 18.  Then you solve

15=2(9)-3 15+3=18

B. 13 units
C 15 units
D. 16 units

Answers

b because i reviewed that with my teacher

The solution is, 12units is the perimeter of AABC.

Here, we have,

Perimeter of ∆ABC = AB + BC + AC

Formula: distance= √(x_2-x_1)²+(y_2-y_1)²

Distance between A(1, 1) and B(4,1):

Where,

AB = √(4-1)^2 + ( 1-1)^2

AB = 3 units

Distance between B(4,1) and C(4,5)

Where,

BC = √(4-4)^2 + (5-1)^2

BC = 4 units

and, we have,

AC = 5 units

so, we get,

Perimeter of ∆ABC = 3+4+5

                                    = 12 units

The scatter plots shows the strongest correlation in graph A. Therefore, option A is the correct answer.

What is scatter plot?

Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.

A strong positive or negative correlation graph is where the line touches or is very close to every data point, and the line has a positive or negative slope.

From the graph A, we can see the points are closely aligned.

3. Matt and his friends paid $30 for 4 sandwiches and 4 bottles of water. Each sandwich cost the same amount. The bottles of water cost $2 each. how much does the sandwich cost

Answers

Answer:

1. 3x + 2

2. 0.25x - 6.5

3. $5.50 per sandwich

Step-by-step explanation:

1.

6x + 1 - (3x - 1)

PEMDAS says solve everything in the parentheses first

There is nothing left to simplify within the parentheses.

Since there's also no exponents, multiplication, or division, let's combine like terms starting from left to right

6x - 3x + 1 + 1

Negative + Negative = Positive, hence why it became 1 + 1

3x + 2

2.

(3x - 1) - 2.75 (x + 2)

PEMDAS says to do multiplication next (since parentheses are fully simplified and there are no exponents)

(3x - 1) - 2.75x - 5.5

Negative + Positive = Negative, hence why it became -5.5

3x - 1 - 2.75x - 5.5

Combine like terms

3x - 2.75x - 1 - 5.5

0.25x - 6.5

3.

Set up an equation:

Variable x = cost of sandwiches

4x + 4(2) = 30

4x + 8 = 30

Subtract 8 from both sides to isolate the variable

4x + 8 - 8 = 30 - 8

4x = 22

Divide both sides by 4

4x ÷ 4 = 22 ÷ 4

x = 5.5

$5.50 per sandwich
