Solve for linear equation by substitution
x + 4y = 6
y=-x+3
Answer: y=1 and x=2
Step-by-step explanation:
Substitute the y value in the first equation with the given equation for y. Now that all the terms are the same, you can solve for X by combining like terms.
ie: x+4(-x+3)=6
then
ie: x-4x+12=6
then
ie: -3x=-6
then divide -3 from each side and you'll end with x=2.
Now plug in your x value for the y equation.
ie: y=-2+3
And solve.

A pair of equations is shown below:
y = 3x − 5
y = 6x − 8
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points)
Answer:
Part A: You can solve this by elimination by first multiplying the first equation by -1 and then adding. This will cause the y value to cancel out.
-y = -3x + 5
y = 6x - 8
---------------
0 = 3x - 3
3 = 3x
1 = x
Now since we know that x = 1, we can plug it into either equation to find y.
y = 3x - 5
y = 3(1) - 5
y = 3 - 5
y = -2.
This gives us the ordered pair of (1,-2).
Step-by-step explanation:
Part B: If we graphed these two, they would intersect at (1, -2). This is because when you solve a system using any method, the result is the intersection of the lines. Therefore, you found where they would intersect in Part A.

Step-by-step explanation:
How many solutions are there to this equation? 5x + 2-2(x - 1) = 3x + 4*
Ono solution
O exactly one solution
O at least two solutions
Oinfinitely many solutions
The equation 5x ₊ 2 ₋ 2(x₋1) = 3x ₊ 4 has infinitely many solutions. Examining our findings will allow us to determine which case it is. There are endless solutions if we end up with the identical term on both sides of the equal sign, such as 3 = 3 or 2x = 2x. There are no solutions if we end up with different integers on either side of the equal sign, as in 6 = 5.
Given the equation is 5x ₊ 2 ₋ 2(x₋1) = 3x ₊ 4
First apply the multiplicative distribution law.
5x ₊ 2 ₋ 2x ₊ 2 = 3x ₊ 4
now rearrange the unknown terms to the left side of the equation:
5x ₋ 2x ₋ 3x = 4 ₋ 2 ₋ 2
combine like terms.
0 = 4 ₋ 2 ₋ 2
0 = 0
we get the similar value on both sides of the equal sign, which indicates that the equation has infinitely many solutions.
hence the equation has infinitely many solutions.

Answer:
The length of [tex]\overline{AD}[/tex] is 20 inches
Step-by-step explanation:
The given parameters are;
Triangle ABC is similar to triangle DEC, therefore, we can write, ΔABC~ΔDEC
[tex]\overline{AC}[/tex] = 30 inches
[tex]\overline{BA}[/tex] = 18 inches
[tex]\overline{ED}[/tex] = 6 inches
By similar triangles formula, we have;
[tex]\overline{BA}[/tex]/[tex]\overline{ED}[/tex] = [tex]\overline{AC}[/tex]/[tex]\overline{DC}[/tex]
Substituting the known values gives;
18/6 = 30/[tex]\overline{DC}[/tex]
Therefore, [tex]\overline{DC}[/tex] = 30/(18/6) = 30/18 × 6 = 10
[tex]\overline{DC}[/tex] = 10
[tex]\overline{AD}[/tex] = [tex]\overline{AC}[/tex] - [tex]\overline{DC}[/tex] = 30 - 10 = 20
[tex]\overline{AD}[/tex] = 20 inches.

Yolanda takes out a loan for her college tuition from a bank that charges simple interest at an annual rate of 8.95%. Her loan is for $2900 for 11 months. Assume each month is 1/2 of a year. Answer each part below.
Do not round any intermediate computations, and round your final answers to the nearest cent. If necessary, refer to the list of Onancial formulas.
If the rate of interest is 8.95% and the loan amount is $2900 for 11 months then the amount to be charged after 11 months will be $3137.92.
Given that the rate of interest is 8.95%, loan amount is $2900 and the number of months is 11 and we have to assume each month be 1/12 of a year.
We are required to find the amount to be charged after 11 months.
Simple interest is basically calculated by multiplying the daily interest rate by the principal by the number of days that elapse between payments.
Loan amount=$2900
Interest rate=8.95%
Months=11
Interest of 11 months=(2900*8.95*11/1200)
=$237.92
Total amount=$2900+237.92
=$3137.92
Hence if the rate of interest is 8.95% and the loan amount is $2900 for 11 months then the amount to be charged after 11 months will be $3137.92.
