Ellie completed an algebraic proof to show that V12 + V108 = 8 - 31.
=
V12 + 7108
122 + 1083
42. 33 + 362 - 31
8.32
Which expression can be placed in the blank to correctly complete Ellie's
proof?
Answer:
The answer to your question is given below.
Step-by-step explanation:
To know the correct answer to the question, do the following:
√12 + √108
= 12^½ + 108^½
= 4^½ • 3^½ + 36^½ • 3^½
Factorise
3^½ (4^½ + 36^½)
Recall:
4^½ = √4 = 2
36^½ = √36 = 6
Therefore,
3^½ (4^½ + 36^½) = 3^½ (2 + 6)
= 3^½ • 8
if DE=3x+7, EF=2x-3 and DF=7x-9, find DF

Calculate the product 78.93 x 32.45
Answer:
The answer is 2 561,2785 !!!
The required value is 2,556.2785 which is determined by the multiplication operation.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
The numbers are given in the question, as follows:
78.93 and 32.45
To calculate the product of 78.93 and 32.45, you can use the standard multiplication algorithm.
78.93 x 32.45
Apply the multiplication operation, and we get
2,556.2785
Thus, the required value is 2,556.2785.

If the slope of line c is given, the slope of
which other line is known?
Answer:
Line d
Step-by-step explanation:
Since, transversal b is forming equal degree of angles (95°) with lines c and d.
So, line c || line d
As we know that parallel lines have same slope.
So, If the slope of line c is given, the slope of line d is also known.
Janice is roller skating at a constant speed away from her house. The first half of the street is flat, but the second half has a steep upward hill. Janice moves more slowly as she skates up the hill.
Which graph shows Janice's position as she roller skates away from her house?
A. Z
B. X
C. W
D. Y
Answer:
If I had to guess... I think it would be Y
Step-by-step explanation:
The reason why I think its Y is because the line on the graph seems to go constant till it gets to the tip. As you can see the line is less slanted meaning that she is going slower. (If you know what I mean.. I tend to be bad at explaining things hehe..)

2c + y = 7 solve for y
Answer:
y = 7 - 2c
Step-by-step explanation:
Step 1:
2c + y = 7 Equation
Step 2:
y = 7 - 2c Subtract 2c on both sides
Answer:
y = 7 - 2c
Hope This Helps :)
Answer:
y = 7 - 2c
Step-by-step explanation:
2c + y = 7
=> y = 7 - 2c

a technician charges 25$ per hour plus 50$ for a house call to repair home computers. make a table and a graph to show the cost for 1,2,3, and 4 hours of home computer repair service. is there a direct variation?
Answer:
75$
Step-by-step explanation:
because 25+50=75
Answer:
The graph starts at $75 since the price for call is $50 and 1 hour of work costs $25.
Direct variation is only noticeable at the beginning of the graph after that the function is linear.

What is 4.345 × 10^5 in standard form?
You may need to erase the comma
To get this answer, move the decimal point to the right 5 spaces to go from 4.345 to 434,500
If the exponent was -5, then you would move five spaces to the left.

Enter your answer as a fraction in simplest form in the box.
m =
Answer: m = ½
.........................
Answer:
The answer is -1/2

Explain how to simplify a ratio. Be sure to include an example to support your response
A ratio is an expression used to compare two quantities. A simplified ratio can be taken as is, but if a ratio has not yet been simplified, you should do so to make the quantities easier to compare and understand. In order to simplify a ratio, you divide both terms (both sides of the ratio) by the same number.

Write the equation of the line graphed below.
Answer:
In y intercept form, the equation would be: Y= -1/3x -6
Step-by-step explanation:
In order to find the equation, you can use any points given. In this case, I used (-6,-4) and (-3,-5).
With these points, you must find the slope. The change in our y values is -1 and the change in our x values is +3.
Now we have Y= -1/3x
To find the y intercept, you look on the graph for where there's a point that is lying on y line. In this case (0,-6) is lying on the y line. This means that the Y intercept for our equation is -6. Another example is (0,8), our y intercept would be 8 because the x value is 0!
In conclusion, our equation in y intercept form would be Y= -1/3x-6
Hope this helps!! :)
