Please helppp What's the slope and y intercept of 3x - y = 7

Answer:  A. inverse variation; xy = 20

ANSWER

Step-by-step explanation:  Brainly

B) xy=20

Inverse because it is of the form y=k/x, intuitively you can see that as x increases y decreases, hence "inverse variation".

...............................................................................................................................................

Answer:

Option B is correct

Inverse variation , xy = 20

Step-by-step explanation:

Inverse variation states:

If  

then the equation is in the form of:

or

xy = k            ....[1]

As per the statement:

Given the data:

x : 2 4 8 12

y : 10 5 5/2 5/3

Let any value of x and y to find k:

x = 4 and y = 5

Substitute in [1] we have;

⇒20 = k

or

k = 20

then we get;

xy = 20

Check:

Substitute x = 12  and y = 5/3

⇒ true.

Therefore, the the data in the table represent a inverse variation and an equation to model the data in the table is, xy = 20

Answer:

area = 153.94

Step-by-step explanation:

Diameter = 14. Half of 14 is 7, so radius = 7.

Formula for the area of a circle = π * r^2, so π * 7^2 = 153.93804

Answer: 62

Step-by-step explanation: In the red empty spot, the #5 would go there and in the blue spot the #6 would go there. 8x2=16 and 16+16= 32: t=This is for the to rectangle shapes on both sides. Now for the square in the middle, since the red spot is 5 and the blue is 6, 5x6= 30. So, 30+32=62.

Answer:  it has no solutions

Step-by-step explanation:

if im wrong i owe u

2(x - 3) = 2x + 5     distribute by multiply 2 into the parenthesis.

2x - 6 = 2x + 5

-2x        -2x         subtract 2x on both sides, 2x's will cancel on both sides.

____________

-6 = 5

Since -6 = 5, there is no solution because -6 cannot equal to 5, which is a false statement. Thus, "C. There is no solution." is the correct answer. Hope this helps :)

Step-by-step explanation:

1/2 x (6 x 4) ÷ 3 + 2  

(We do the equation in the parenthesis 1st)

1/2 x 24 ÷ 3 + 2    

(Since it's multiplication and division, we just go from left to right)

Answer:

the area is 32 square inches

Step-by-step explanation:

you multiply both sides that have 9 because they are equal and then you add the 14 on

Answer:

63 Inches

Step-by-step explanation:

The formula for finding the area of a triangle is:

(b*h)/2

First, let's plug in the values.

(14*9)/2

Simplify...

126/2

Divide the two which gives us:

63

Therefore, the answer is:

63 Inches.

Answer:

  r = 0

  r = -7

Step-by-step explanation:

There is no x in the equation, hence there are no x-intercepts.

__

If we assume you want the values of r that satisfy the equation, the zero product property tells you they will be the values that make the factors zero.

The factors are r and (r+7).

The factor r is zero when ...

  r = 0

The factor (r+7) is zero when ...

  r +7 = 0   ⇒   r = -7

The "x-intercepts" are r=0 and r=-7.

Answer:

B) -1 < x < 1

Step-by-step explanation:

A function is positive on intervals (read the intervals on the x-axis), where the graph line lies above the x-axis. A function is negative on intervals (read the intervals on the x-axis), where the graph line lies below the x-axis.

Answer:

[tex]\dfrac{3}{4}\ miles[/tex]

Step-by-step explanation:

Total distance to a temple = 2 miles

She has walked 1 1/4 miles or 5/4 miles

More miles to reach the hidden temple = total distance - walked distance

[tex]=2-\dfrac{5}{4}\\\\=\dfrac{8-5}{4}\\\\=\dfrac{3}{4}[/tex]

So, she has to travel [tex]\dfrac{3}{4}[/tex] miles to reach the hidden temple.

Step-by-step explanation:

To find slope just compare two points on a graph then put them into a fraction like so y₁ - y₂/x₁ - x₂

Answer: [0, 396]

Step-by-step explanation:

The domain is the acceptable values of x in the function.  In this case, x = t, the number of tiles.  If you think about it, the minimum number of tiles is 0 (you can't have a negative number of tiles), and the maximum number of tiles is 44 (you only have 44 tiles).  So, the domain for this function is from 0 to 44.

0 to 44 written in interval notation is [0,44].

The range is the acceptable values of y in the function.  In this case, y = A, the area given.  A(t) = 9t, so you can use the acceptable values of t to get the range.  Again, the minimum area is 0 because you can't have negative area. To find the maximum area, plug in the maximum number of tiles: 9.

A(t) = 9t

A = 9(44)

A = 396

With the maximum number of tiles, 44, the area you get is 396 cm².  Therefore, the acceptable values of A are from 0 to 396.

0 to 396 written in interval notation is [0, 396].

Answer:

The first bottle holds 10 ounces of water.

Step-by-step explanation:

The bottle holds z ounces.

The second bottle holds 16 ounces, which is 8/5 times the first, which is z.

How much water does the first bottle holds?

[tex]\frac{8z}{5} = 16[/tex]

[tex]8z = 16*5[/tex]

[tex]8z = 80[/tex]

[tex]z = \frac{80}{8}[/tex]

[tex]z = 10[/tex]

The first bottle holds 10 ounces of water.
