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

A.y = 2x - 5
B.y = 2x + 5
C.y = 2x - 3
D.y = 2x + 3
9514 1404 393
Answer:
C. y = 2x - 3
Step-by-step explanation:
The y-intercept (b) can be found from ...
y = mx + b
y - mx = b . . . . . subtract mx
Here, you are given (x, y) = (-1, -5) and slope m = 2.
b = -5 -2(-1) = -5+2 = -3
The correct equation is ...
y = 2x -3 . . . . . matches choice C
_____
On the graph, you can plot point (-1, -5) left of the y-axis 1 unit and down from the x-axis 5 units. The slope of 2 tells you the line will rise 2 units from there to a y-value of -3 when it runs 1 unit to the right to an x-value of 0. That point (0, -3) is the y-intercept, showing you that choice C is correct.

IMPORTANT THIGNS TO REMEMBER:
Has 20 lb. dog food!Gives dog 1 3/5 everyday!Find how much eaten after 2 days!Find how much is left!ANSWER:
Dog has eaten 3 1/5 after 2 days!
There is 16 4/5 left in bag!
EXPLANATION:
Since she gives 1 3/5 to her dog everyday and their asking for 2 days you would multiply 1 3/5 × 2 OR add 1 3/5 + 1 3/5
Which would give you 3 1/5
So, the dog has eaten 3 1/5 lb. of dog food in 2 days.
However then, you would subtract 20 lb. - 3 1/5 lb. because there is 20 lb. dog food in all and the dog has eaten 3 1/5 of it. This would give you 16 4/5 lb.
Meaning there is 16 4/5 lb. left in the bag of dog food!

how do you find the slope and y intercept
Answer:
The slope is -2/3 and the y intercept is 1
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -2/3 x+1
The slope is -2/3 and the y intercept is 1

the next algebra test is worth 100 points and contains 35 problems. multiple-choice questions are worth 2 points each and word problems are 7 points each. how many of each type of equation are there? Please leave steps.
Answer:
29 multiple choice questions, 6 word problems
Step-by-step explanation:
2x + 7y = 100
x + y = 35
y = 35 - x
2x + 7 (35 - x) = 100
2x - 7x + 245 = 100
-5x = -145
x = 29
29 + y = 35
y = 6

Determine which function(s) are exponential. Select all that apply.
Answer:
option B and option C represent an exponential function.
Step-by-step explanation:
We know that following are some of the properties of different functions.
Linear Function:
The constant change in x and y
Quadratic Function:
The constant change in x
The constant 2nd differences in y
Exponential Function:
The constant change in x
The constant ratio in y
Determining the nature of the exponential function
Option A)
x 0 1 2 3 4
y 0 1 4 9 16
Here:
There is a constant change in x:
1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1
BUT, there is NO CONSTANT ratio, as
1/0 = ∞, 4/1 = 4, 9/4 ; 16/9
Thus,
Table A DOES NOT represents an exponential function.
Option B)
x 0 1 2 3 4
y 1/3 1 3 9 27
Here:
There is a constant change in x:
1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1
There is also a constant ratio, as
1/[1/3] = 3, 3/1 = 3, 9/3 = 3; 27/9 = 3
As there is constant change in x as well a constant ratio.
Thus,
Table B REPRESENTS an exponential function.
Option C)
x 0 1 2 3 4
y 5 5/2 5/4 5/8 5/16
Here:
There is a constant change in x:
1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1
There is also a constant ratio, as
[5/2]/5= 1/2,
[5/4]/[5/2] = 1/2
[5/8]/[5/4] = 1/2
[5/16]/[5/8] = 1/2
As there is constant change in x as well a constant ratio.
Thus,
Table C REPRESENTS an exponential function.
Option D)
x 0 1 2 3 4
y 4.5 4 3.5 3 2.5
Here:
There is a constant change in x:
1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1
BUT, there is NO CONSTANT ratio, as
4/4.5 = 4/[45/10] = 40/45 = 8/9
3.5/4 = [35/10]/4 = 35/40 = 7/8
3/3.5 = 3/[35/10] = 30/35 = 6/7
2.5/3 = [25/10]/3 = 25/30 = 5/6
Table D DOES NOT represent an exponential function.
Conclusion:
Therefore, option B and option C represent an exponential function.
The functions that are exponential would be:
B). [tex]x[/tex] 0 1 2 3 4
[tex]y[/tex] 1/3 1 3 9 27
C). [tex]x[/tex] 0 1 2 3 4
[tex]y[/tex] 5 5/2 5/4 5/8 5/16
What are Exponential Functions?
B). Given that,
[tex]x[/tex] 0 1 2 3 4
[tex]y[/tex] 1/3 1 3 9 27
As we see,
The value of [tex]x[/tex] undergoes a constant change of 1
[tex]1 - 0 = 1; \\2 - 1 = 1; \\3 - 2 = 1; \\4 - 3 = 1[/tex]
The ratio also remains constant
[tex]1/[1/3] = 3, \\3/1 = 3, \\9/3 = 3; \\27/9 = 3[/tex]
Thus, it exemplifies an exponential function.
Similarly,
C). [tex]x[/tex] 0 1 2 3 4
[tex]y[/tex] 5 5/2 5/4 5/8 5/16
As we see,
The value of [tex]x[/tex] undergoes a constant change of 1
[tex]1 - 0 = 1; \\2 - 1 = 1; \\3 - 2 = 1; \\4 - 3 = 1[/tex]
The ratio also remains constant
[tex][5/2]/5= 1/2\\\\[5/4]/[5/2] = 1/2\\\\[5/8]/[5/4] = 1/2\\\\[5/16]/[5/8] = 1/2[/tex]
Thus, it exemplifies an exponential function.
Thus, options B and C are the correct answers as the other two have a constant change but not a constant ratio.

The width of a rectangle measures (2p-5) centimeters, and its length measures (8p+8)centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer: The expression that represents the perimeter, in centimeters, of the rectangle=20p + 11 centimeters
Step-by-step explanation:
Perimeter of a rectangle = 2(l+w)
length measures (8p+8)centimetres.
width measures (2p-5) centimeters,
Such that Perimeter= 2 L +2 W
Perimeter= 2( 8p+8) + 2(2p-5 ) This gives the expression to solve for the Perimeter
Solving
Perimeter= 2( 8p+8) + 2(2p-5 )
Permeter= 16p+ 16+ 4p-5
Perimeter= 16p+4p+16-5
Perimeter= 20p + 11 centimeters
