B)4x−3y=10
C)4x−3y=−10
D)3x−4y=−10
2.What is the slope-intercept form of the linear equation x + 4y = 12? Enter your answer in the box.
3.Graph the equation on the coordinate plane. y=1/2x
Answers
Answer: 1. A) 3x−4y=10
2. [tex]y=-\frac{x}{4}+3[/tex]
3. In the attachment.
Explanation:
1. Given equation=[tex]y=\frac{3}{4}x-\frac{5}{2}[/tex]
To reduce it into standard form , multiply both sides by 4,we get
[tex]4y=4(\frac{3}{4}x-\frac{5}{2})\\\Rightarrow4y=3x-10......[distributive\ property]\\\Rightarrow3x-4y=10[/tex] which is option A.
2. Given linear equation : x+4y=12
The standard slope intercept form is given by y=mx+c where m is the slope and c is the constant.
To reduce given linear equation subtract x from both sides, we get
4y=12-x
Divide 4 on both sides.
[tex]\Rightarrow\ y=\frac{12-x}{4}=3-\frac{x}{4}\\\Rightarrow\ y=-\frac{x}{4}+3[/tex] is the slope-intercept form of the linear equation x + 4y = 12.
3. To graph equation [tex]y=\frac{1}{2}x[/tex] on the coordinate plane.
We need to find points to plot the line

Help. What is the slope.
Answers
----------------------------------------------------------
----------------------------------------------------------
Explanation:
There are two basic ways to find the slope.
-----------------------------------
The first way is where we use the slope formula
m = (y2-y1)/(x2-x1)
The two points are (x1,y1) = (-1,8) and (x2,y2) = (2,-4)
Plug the coordinate of those points into the slope formula, then simplify
m = (y2-y1)/(x2-x1)
m = (-4-8)/(2-(-1))
m = (-4-8)/(2+1)
m = (-12)/(3)
m = -4
The slope is -4
-----------------------------------
The second way is to use a more visually oriented approach.
Start at (-1,8).
Draw a straight vertical line through this point. Then move to the point (2,-4) and draw a completely flat horizontal line through this point.
Mark the intersection between these two lines (vertical and horizontal) as point A
Now go back to (-1,8). Count the number of spaces you must move down to go from (-1,8) to point A. You should count out 12 spaces. This is the run, which in this case is negative since we're going downhill as we move from left to right
Then count 3 spaces to go from point A to (2,-4). This is the run
Rise = -12
Run = 3
Slope = Rise/Run = -12/3 = -4
As you can probably see, this effectively mirrors some parts of the slope formula above
No matter which method you use, the slope is -4
-4 is the same as -4/1
A slope of -4/1 means we go down 4 units and then move to the right 1 unit
So that means rise/run = -12/3 is the same as saying rise/run = -4/1

Write the expressions as a difference and simplify it: 17x−13y+8 and 20x+6y.
Answers
The two expressions 17x−13y+8 and 20x+6y can be rewritten as a difference to be -3x - 19y + 8.
Explanation:To rewrite the two expressions 17x−13y+8 and 20x+6y as a difference, you can first list them separately and then combine by subtraction.
17x - 13y + 8
and
20x + 6y
. The difference between these two expressions is obtained by performing the subtraction as follows: (17x - 13y + 8) - (20x + 6y). Now, you can simplify this by removing the parentheses and switching the sign of the terms being subtracted, which results in:
17x - 13y + 8 - 20x - 6y
. Finally, you combine like terms, x-terms with x-terms and y-terms with y-terms, ending up with:
-3x - 19y + 8
which is the simplified difference of the two expressions.

Alex and Freddy collect stamps. The number of stamps in Alex’s collection is in ratio 3:5 to the number of stamps in Freddy’s collection. If Freddy gives Alex 10 stamps, the ratio will change to 7:9. How many stamps are in both collections together?
Answers
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160
Answer:
160 stamps
Step-by-step explanation:
Suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
The new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have

A bike wheel is 26 inches in diameter. What is the bike wheel's diameter in millimeters (1 inch = 25.4 millimeters)?
Answers
Given that, a bike wheel is 26 inches in diameter.
We need to convert bike wheel's diameter in millimeters .
Since, 1 inch = 25.4 millimeters.
So, to convert 26 into mm we need to multiply 26 each sides of this identity to convert this into mm. Hence,
1*26 inch = 25.4 * 26 mm.
So, 26 inches = 660.4 mm.
So, the bike wheel's diameter is 660.4 millimeters.
Hope this helps you!
The bike wheel's diameter of 26 inches is equivalent to 660.4 millimeters.
To convert a bike wheel's diameter from inches to millimeters,
we have to use the conversion factor, which is,
1 inch = 25.4 millimeters.
Now multiplying the diameter of the bike wheel,
which is given as 26 inches,
by the conversion factor of 25.4 millimeters per inch.
⇒ 26 inches x 25.4 millimeters per inch = 660.4 millimeters
Therefore, the diameter of the bike wheel in millimeters is 660.4 millimeters.
Therefore, we can convert inches to millimeters by multiplying by 25.4, which is the number of millimeters in one inch.
In this case, the bike wheel's diameter of 26 inches is equivalent to 660.4 millimeters.

This could be answered by using the distributive property.
This is an algebra property which is done to multiply a particular term and two or more terms in a set of parentheses.
So for our problem, 6 (3 + 9):
You first, multiply 6 x 3 = 18
And multiply 6 x 9 = 56
Thus, the answer is 18 + 56 = 72
But following the order of operations, you should add first the number inside the parenthesis and then multiply it to the number outside the parenthesis but it will the same answer still. (6 x 12 = 72)
