I need answer on this graphing va substitution.Problem 7 I tried to solve it but not sure that’s correct
Bond [772]

Given the system of equations:

\begin{gathered} 2x+9y=27 \\ x-3y=-24 \end{gathered}

To solve it by substitution, follow the steps below.

Step 1: Solve one linear equation for x in terms of y.

Let's choose the second equation. To solve it for x, add 3y to each side of the equations.

\begin{gathered} x-3y=-24 \\ x-3y+3y=-24+3y \\ x=-24+3y \end{gathered}

Step 2: Substitute the expression found for x in the first equation.

\begin{gathered} 2x+9y=27 \\ 2\cdot(-24+3y)+9y=27 \\ -48+6y+9y=27 \\ -48+15y=27 \end{gathered}

Step 3: Isolate y in the equation found in step 2.

To do it, first, add 48 to both sides.

\begin{gathered} -48+15y=27 \\ -48+15y+48=27+48 \\ 15y=75 \end{gathered}

Then, divide both sides by 15.

\begin{gathered} \frac{15y}{15}=\frac{75}{15} \\ y=5 \end{gathered}

Step 4: Substitute y by 5 in the relation found in step 1 to find x.

\begin{gathered} x=-24+3y \\ x=-24+3\cdot5 \\ x=-24+15 \\ x=-9 \end{gathered}

Answer:

x = -9

y = 5

or (-9, 5)

Also, you can graph the lines by choosing two points from each equation, according to the picture below.

Caeli is designing a flag that will be in the shape of a rectangle. She has 10 square feet of fabric to use, and she wants the h
vampirchik [111]

Answer:

<u>If Caeli  will use all of the fabric she has, the base of the flag should be of 4 feet.</u>

Step-by-step explanation:

1. Let's review the information provided to answer the question correctly:

Area of the fabric Caeli  has and want to use and design = 10 square feet

Height of the rectangle of the rectangle shape = 2.5 feet

2.  What is the base of the flag if she will use all of the fabric she has?

Area of the shape of the rectangle = Height of the flag * Base of the flag

Replacing with the real values:

10 square feet = 2.5 feet * Base of the flag

10 square feet/2.5 feet = Base of the flag

<u>Base of the flag = 4 feet</u>

<u>If Caeli will use all of the fabric she has, the base of the flag should be of 4 feet.</u>
