I decided to add a room to my house and now need to know the total square feet of the house. The dimensions of the original house are (X + 8) by (x + 12) and the dimensions of the new addition are x by (x + 6). What is the total area of my new house. What's the area of the original house? What's the area of the new addition? What's the total area of the house?
Answer:
+) the area of the original house is:
(x + 8)(x + 12) = x² + 20x + 96.
+) the area of the new addition is:
(x + 6)x = x² + 6x
+) the total area of the house is:
x² + 20x + 96 + x² + 6x = 2x² + 26x + 96

Graphs that show a linear function is second option
The linear equation graphs are the equation of straight line graph with slope.
for example y = mx where (x,y) be the point on the line and m be the slope.
here the only second graph shows a straight line graph. y values changes by when x value changes. there is a slope.
when we a x value we can compute the corresponding y value.
Step-by-step explanation:
Graph the line that has a slope of −13 and contains the point (3,−7)
Graph the line that has a slope of −13 and contains the point (3,−7) intercept is 32.
straight line graph can be represented two form
cartesian form ax+ by +c=0
slope intercept form y=mx +c
Where m is slope and c is the intercept in y axis
Value of m = change in y/change in x
back to question :- slope is -13
So, [y2-y1]/[x2-x1]= -13
{y+7/x-3 } = -13
y+7 = -13x +39
for intercept just put x=0
so y = 39-7
y=32
y= -13x +32
slope = -13
intercept = 32
Graph the line that has a slope of -1/3 and contains the point (3-7)
Plot the point (3,-7)
slope = -1/3 means y decreases 1/3 when x increases by 1
Let x increase by 3, then y decreases by 3(1/3) = 1
Put your pencil at (3,-7)
Increase x by 3 to (6,-7)
Decrease y by 1 to (6,-8)
Plot the point (6,-8)
Draw the graph as a line thru (3,-7),(6,-8)

A hoodie is on sale for $48. This sale price is 80% of the original price. What was the original price of the hoodie?
Answer: 60 dollars
===============================================
Work Shown:
x = original price
y = sale price
The sale price is always smaller than the original price, so y < x.
The equation linking the two variables is
y = 0.8x
since 80% = 80/100 = 0.8
We know the sale price is $48, which means y = 48. This leads to:
y = 0.8x
0.8x = y
0.8x = 48
x = 48/0.8
x = 60
The original price was $60
Note: since the sale price is 80% of the original price, this must mean that we have a 20% discount (100% - 80% = 20%)

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.

Select the solution(s) to the following equation: (3x−2)(x+5)=0 SELECT ALL THAT APPLY
x=3/2
x=5
x=-5
x=2/3
x=-2/3
x=-3/2
Answer:
Step-by-step explanation:
Check by direct substitution. If we begin by checking x = 3/2, we substitute 3/2 for x in (3x - 2)(x + 5), obtaining (9/2 - 2)(3/2 + 5), which is NOT zero. Therefore x = 3/2 is not a solution.
(3*5−2)(5+5)=0 False. x = 5 is not a solution.
(3*[-5]−2)([-5+5)=0 True. x = -5 is a solution
x = 2/3: (3*2/3 - 2)( ) = 0. True x = 2/3 is a solution
x = -2/3: ( )( ) = -17 1/3; so x = -2/3 is not a solution
x = -3/2: ( ) ( ) = -22 3/4; so x = -3/2 is not a soution

solve: 2x+3y=1
y=-2x+11
Answer:
(8, -5); x=8; y=-5
Step-by-step explanation:
i'll be solving via substitution
2x+3y=1; y=-2x+11
2x + 3(-2x +11) = 1
2x -6x +33 = 1
-4x = -32
x = 8
2(8) + 3y = 1
16 + 3y = 1
3y = -15
y = -5
(8, -5)
Check:
-5 = -2(8) + 11
-5 = -16 + 11
-5 = -5
