y = 6x -11
-2x - 3y = -7

Answers

Answer:

x = 2

y = 1

Step-by-step explanation:

1) Re-arrange

(Solving for y)

-2x -3y = -7    -->  x3

6x - y = 11    -->  x1

-6x -9y = -21

6x -y = 11

-9y = -21

-y = 11

(-9y + -y) = (-21 + 11)

-10y = -10    

y = -10/-10

y = 1

2) Substitute

6x - 1 = 11

6x = 11 + 1

6x = 12

x = 12/6

x = 2

Answer: x = 2, y = 1

Step-by-step explanation:

Rearrange the second equation so it just works a little easier for you:

-2x - 3y = -7

rearranged to make y (with its constant) the subject:

3y = 7 - 2x

So we know what y equals. The question tells us y = 6x - 11. So substitute those values into the rearranged equation.

3y = 7 - 2x   becomes:

3(6x - 11) = 7 - 2x

because as stated in the question, y = 3x - 11.

Expand the brackets on the left-hand side:

18x - 33 = 7 - 2x

Rearrange to collect like terms:

18x = 7 + 33 - 2x

18x = 40 - 2x

18x + 2x = 40

20x = 40

x = 40/20

x = 2.

So now we know the value of x.

Let's input our new found value of x into one of the given equations, such as y = 6x - 11.

y = (6 * 2) - 11

y = 12 - 11

y = 1.

So y = 1.

You can test this by inputting these values into the other equation, for assurance.

-2x - 3y = -7 becomes:

(-2 * 2) - (3 * 1) = -7

(-4) - 3 = -7

-7 = -7

Two quantities are related as shown in the table. Which equation best represents the relationship? ​

A bike wheel is 26 inches in diameter. What is the bike wheel's diameter in millimeters (1 inch = 25.4 millimeters)?

Answers

Answer:

660.4 mm

Step-by-step explanation:

Since 1 inch is equal to 25.4 millimeters, we can multiply 25.4 by 26 to see how many millimeters 26 inches is. You can also think of this as a proportion:

26:x = 1:25.4

26.4 times 26 is equivalent to 660.4, so we can conclude that 26 inches are equivalent to 660.4 millimeters.

given l is parallel to m, find the measure of angle ptu

Answers

Answer:

Angle ptu = 116°

as line L is parallel to m

angle pqt = 89° ( vertically opposite angle)

angle tpq = 3x° ( vertically opposite angles).

in triangle pqt

angle p + angle q + angle t = 180° (angle sum proper of a triangle)

Let the unknown angle ptq be X

3x + 89 + X = 180°

3x + x + 89 = 180

4x + 89 = 180

4x = 180 - 89

4x = 91

x = 27°

angle u = 89° ( corresponding angles)

angle ptu = 89 + 27

= 116°

Hey can anyone help with this question please and thank you

Answers

Answer:

x = 16

Step-by-step explanation:

7x + 9 = 9x - 23

9 + 23 = 9x - 7x

32 = 7x

32 / 7 = x

16 = x

Since < (7x + 9) is an interior angle and < (9x - 23) an exterior angle — these angles are on the same side of the transversal, line t. Therefore, they are corresponding angles with the same measure.

Hence, we can establish the following equality statement to solve for x:

< (7x + 9) = < (9x - 23)

Subtract 7x from both sides:

7x - 7x + 9 = 9x - 7x - 23
9 = 2x - 23

Add 23 on both sides:

9 + 23 = 2x - 23 + 23
32 = 2x

Divide both sides by 2 to solve for x:

32/2 = 2x/2
16 = x

Therefore, x = 16.

Substitute x = 16 into the equality statement to verify whether it is the correct value:

< (7x + 9) = < (9x - 23)
7(16) + 9 = 9(16) - 23
112 + 9 = 144 - 23
121 = 121 (True statement. Therefore, x = 16 is the correct answer).

The endpoints of a side of rectangle ABCD in the coordinate plane are at A(3,5) and
B(5, 1). Find the equation of the line that contains the given segment.
The line segment is AB.
The equation is y =

Answers

Step-by-step explanation:

the equation is

y = ax + b

a is the slope of the line. this is the ratio y/x indicating how many units y changes, when x changes a certain number of units.

so, when we go from A to B, x changes 2 units (from 3 to 5), and y changes -4 units (from 5 to 1).

so the slope is -4/2 = -2

now or equation looks like

y = -2x + b

to get b we use one of the points in the equation. e.g. B

1 = -2×5 + b = -10 + b

b = 11

so, our full equation is

y = -2x + 11

Answers

I marked the pockets in red in the picture. The first goes in the bottom right, the second goes in the top left. And so on.

Explanation:
I think the easiest way is to simplify them all, so that you can find which ones are equal! I marked the pockets in red on each door. But for example, 3/6 is equal to 1/2 because if you multiply 1/2 x 3/3 you get (1 x 3)/ (2 x 3) or 3/6. So the goal is to find a number you can divide the fraction by. You can see if it’s all the way simplified you can no longer divide the top and bottom by the same number. In the second door, you could start by dividing by 2: 4/8 divided by 2/2 is 2/4. But now we can divide by 2 again: 2/4 divided by 2/2 is 1/2. And 1/2 matches one of our pockets, the top left one!

Answer:

16 * (cube root of 0.5)

Step-by-step explanation:

Radius of the big cone = 12 cm / 2 = 6 cm

Let r = radius of the small cone (cone of water), and h = the height of the small cone

Also, r / h = 6 / 16, so that h = (16/6)r = (8/3)r.

Thus, since the volume of the big cone = (1/3)π(r^2*h)=(1/3)π(6^2*16), and the volume of the small cone = (1/3)π(r^2*h)=(1/3)π(r^2*(8/3)r) = (1/3)π(r^3*(8/3)), and the volume of the small cone is half the volume of the big cone, we have that

(1/3)π(r^3*(8/3))=(1/2)((1/3)π(6^2*16))

(r^3*(8/3))=(1/2)((6^2*16))

r^3 = (3/8)(1/2)(6^2)(16)

r^3 = (1/2)(6^3)

r = (cube root of 1/2)(6),

and

h = (8/3)r = (8/3)(cube root of 1/2)(6) = 16(cube root of 1/2), the depth of the water.

 

   

What is the slope of the line on the graph?

Answer:

-2

Step-by-step explanation:

To find the slope pick ANY 2 points on the line and see what you had to do to get from one point to another point.

Keep in mind that slope = rise/run , or m = difference in y /difference in x

For example, Start at (0,0) and Go to (6,-3)

To get from one point to the other you have to go up 6 and left 3 so slope is
