You have to solve the problem \frac{3}{4}-\frac{1}{8} ​4 ​ ​3 ​​ − ​8 ​ ​1 ​​ . After you make the denominators the same, what do you do? A You subtract the numerators but keep the denominators the same. B You subtract the numerators and you subtract the denominators. C You subtract the denominators but keep the numerators the same. D You subtract the numerator from the denominator, and that becomes the new numerator.

Answers

Answer:  The correct answer is A) You subtract the numerators but keep the denominators the same.

A is the answer for this question

oints (−6, 3) and (−6, −3) on the coordinate grid below show the positions of two dogs at a park:

A coordinate plane is shown. There is a point at negative 6, 3 labeled Dog 1. There is a point at negative 6, negative 3 labeled Dog 2.

Which statement best describes the relationship between the positions of the two players? (4 points)

a
Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
b
Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
c
Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.
d
Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.

Answers

Answer: B

Explanation:

Correct way to write down co-ordinates: x,y

Dog 1's position: (-6,3)

Dog 2's position: (-6,-3)

Similarity: Both co-ordinates have -6 on the X axis (left to right line)

Difference: Dog 2's Y co-ordinate is NEGATIVE 3 while dog 1's Y co-ordinate is POSITIVE 3

The position is going to be reflected across the X axis because their X co-ordinates are the same, so dog 1 will be on the positive section for the Y axis (line that goes up and down) while Dog 2 will be on the negative section of the Y axis since it has negative 3 as its Y co-ordinate.

B IS THE CORRECT ANSWER

Answers

Answer:

1. Anything to do with the same slope but different a B (Ex.  y=1/3x+1 and y=1/3x-8)

2. No solutions

Step-by-step explanation:

1. Because the two lines are parallel, when no intersection between two lines happens, there will need to be a change in the B but the same slope. Remember the formula for an equation is y=mx+b. The m stands for the slope. With parallel lines, slopes are the same. If lines were to never intersect, you would have to change the b to a different number so that both lines could keep going at the same time, but never intersect.

2. Remember, solutions only happen when the two lines intersect. Infinite solutions happen when the lines are the same. One solution happens when two lines only have one point where they intersect. No solutions happen when the two lines don't intersect at all. Based off the graph given, there are no intersections so, there will be no solutions.

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

X = 2.5

Answer:

\(x=39\)

Step-by-step explanation:

\(-2\left(x+5\right)-4+3\left(x-8\right)=1\)

Add 4 to both sides:

\(-2\left(x+5\right)-4+3\left(x-8\right)+4=1+4\)

\(-2\left(x+5\right)+3\left(x-8\right)=5\)

Expand:

\(-2x-10+3\left(x-8\right)=5\)

\(-2x-10+3x-24=5\)

\(x-34=5\)

Add 34 to both sides:

\(x-34+34=5+34\)

\(x=39\)
