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

/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

Hank is throwing a surprise party. The party costs $20 per person. Create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.
The independent variable is ____.
A. Number of friends (f)
B. Cost of party (c)
The equation __________ can be used to represent this relationship.
c = 20f
f = 20c
c = 10f
f = 10c
Hank is throwing a surprise party. The party costs $20 per person. Create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.
If 50 people attend, what is Hank's cost? $_____
Complete the following table:
Number of friends (f) *? 10 *? 20
Cost of party (c) 100 *? 300 *?
Plots the points from the table onto the graph
Answers
Answer:
b.cost of party
c=20f
Step-by-step explanation:
so we know the equation we have to use is c=20f
for part 2 we have to find out how much it's going to cost hank if 50 people attend his party;
so we know that 'c' is our unknown variable; now we write the equation filling in the 'blanks' with what we know-
c=20*50
now we multiply **remember that when you have a number and a letter right next to each other that they're being multiplied**
20*50
=1000
so hank will be spending $1000
good luck :)
hopefully, this helps

Find the measures of the following angles given in the diagram below.
Answers
Answer:
1st Question:
m<1 = 90°
m<2= 79°
m<3= 101°
2nd Question:
m<1=97°
m<3=83°
m<6=83°
Step-by-step explanation:
1st Question :
m<1 is a right angle.
m<2 is 79° because of parallel line denote the same angle.
m<3 is 101° because 180°-79°=101°.( As we know sum of angles in a straight line = 18° degree. )
2nd question:
m<1 is 97° because sum of angles in a straight line = 180°
So, 180°-83°=97°
m<3 is 83° because sum of parallel sides are equal.
m<6 is 83° because sum of parallel sides are equal.

-2x-10=2x+14 i need all the steps
Answers
Answer:
x = -6
Step-by-step explanation:
1. always group the unknowns in this case, we 'bring' over the -2x to the right side so it becomes
-10 = 2x + 2x +14
2. Move 14 to the left side,
-10 - 14 = 2x + 2x
3. Carry out addition on both sides,
-24 = 4x
4. Simplify: since 24 is divisible by 4, so we divide 4 on both sides
-6 = x
Answer: x=-6.
Step-by-step explanation:
First, we need to choose an x side, and a non-x side. Let's choose the right side as the x side since it's coefficient of x is greater than that of the left side. So, we add 2x on each side to get rid of the x on the left side. Now, we have -10=4x+14. Next, we should subtract 14 from each side to get rid of the non-x terms on the right side. Now, we are left with -24=4x. Finally, we can divide by four on each side to get x=-6.

Step-by-step explanation:
Answer: 15-12s
Step-by-step explanation:
Because the number (-3) is in front of the bracket that means that you have to times everything inside by it.
So,
-3×-5=15
-3×4s=-12s
So the answer would be 15-12s

Which of the following scatter plots shows the strongest correlation
Answers
Answer:
the first one
Step-by-step explanation:
the reason this is because it is showing a linear graph and when it comes to correlation it has to be linear
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.
Therefore, option A is the correct answer.

Questions are in the Picture
Answers
Answer:
Step-by-step explanation:
For problem 10:
1. AE/ED=AC/CB (Since triangle ABC is similar to triangle ADE, we can determine that the ratio of AE to ED is equal to the ratio of AC to CB)
2. AE/ED=(AE+EC)/CB (Rewrite AC as the sum of the lengths forming it; This is sometimes referred to as the Partition Postulate)
3. 9/x=(9+6)/10 (Substitute the given values into this equation)
4. x=6 (Use algebra to solve for x)
For problem 11:
1. AG/AB=AE/AD (Use the same strategy as step one in problem 10, since the rectangles are similar we can create this equation)
2. AG/(AG+GB)=AE/(AE+ED) (Rewrite sides as the some of their parts)
3. 14/(14+7)=18/(18+x) (Substitute given values)
4. x=9 (Solve for x)
