Solve the system by substitution.
1. y = -6x – 7
y = -7x
2. -y=x
3x+5y=20
Answer:
For no. 1:
One of the equations say that y=-7x
So plug in -7x to the other equation as y so you equation would be
-7x= -6x-7
And then, just solve for the variable:
*add -6x to both sides*:
-x= -7
*multiply both by negative one to get a positive variable*
FOR NUMBER 1, THE ANSWER IS:
x=7
Y=-7
For no. 2:
-y=x and your other equation is 3x+5y=20
Plug in x as -y:
-3y+5y=20
*simplify*
2y=20
*divide by 2 on each side to get 1 variable alone*
Y=10
FOR NUMBER 2, THE ANSWER IS:
x=-y
Y=10

A child building a tower with Blocks uses 15 for the bottom row. Each row has 2 fewer blocks than the previous row. What formula would you use to find the number of blocks in the 5th row?
A)blocks in 5th row =15+(15-1)-2
B)blocks in 5th row=15+(5-1)(-2)
C)blocks in 5th row=15+(5+1)(-2)
D)blocks in 5th row=5+(15-1)(-2)
Answer:
B)blocks in 5th row=15+(5-1)(-2)
Step-by-step explanation:
We are given that
Number of block in bottom row=15
Each row has 2 fewer blocks than the previous row
We have to find the formula would you use to find the number of blocks in the 5th row.
Number of blocks in second row=15-2=[tex]15+1(-2)[/tex]
Number of blocks in third row=15-2-2=[tex]15+2(-2)[/tex]
Number of blocks in 4th row=[tex]15-2-2-2=15+3(-2)[/tex]
Number of blocks in 5th row=[tex]15-2-2-2-2=15+4(-2)[/tex]
Therefore, number of block in 5th row
[tex]15+(5-1)(-2)[/tex]
This is required formula to find the number of blocks in the 5th row
Hence, option B is true.
B)blocks in 5th row=15+(5-1)(-2)

Helppp. Write an equation to solve for a. Then find the missing angle.
Answer:
180 = 90 + 52+ a
38 =a
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
180 = 90 + 52+ a
Combine like terms
180 = 142+a
Subtract 142 from each side
180 -142 = 142+ a -142
38 = a

Please check the explanation.
Step-by-step explanation:
Given the function representing the number of customers on day x
f(x) = 3ˣ
Part A)
We need to determine the day when there are 243 customers.
so substitute f(x) = 243 in the function
[tex]f\left(x\right)\:=\:3^x[/tex]
Part B)
Solving the equation
[tex]f\left(x\right)\:=\:3^x[/tex]
[tex]243\:=\:3^x[/tex]
as 2⁵ = 243, so
[tex]\:2^5=3^x\:[/tex]
x = 5
The value of x = 5
Part C)
As the value of x = 5
Therefore, on the 5th day, there would be 243 customers.

6x + y = -1
y=-3x - 4
Answer:
x = 1, y = 7
Step-by-step explanation:
If y = -3x - 4, then
6x -3x -4 = 1
3x - 4 =-1
3x = 3
x = 1
If x = 1, then
y = -3*1 -4 = -3 -4 = -7
