Answer:

x = 3y + 87

Step-by-step explanation: Hi! Ok, firstly, you know the slope, which is:

3y = x - 6

y = 1/3x - 2

Your slope is 1/3.

And you have the point (8,5). If you were to graph this, your y-intercept will be (0,29), because for every one you add to the y value, you add three to x. So, you have to add 8 to y, so 24 to x. 24 + 5 = 29.

Thus, y-intercept form is y = 1/3x + 29

Standard form will be: x = 3y + 87

Answer:

Subtract 9 from each side of the equation.

m = – 11

Step-by-step explanation:

m + 9 = – 2

To solve the above equation, we simply subtract 9 from each side of the equation.

This is illustrated below:

m + 9 = – 2

Subtract 9 from each side of the equation

m + 9 – 9 = – 2 – 9

m + 0 = – 11

m = – 11

Therefore, the value of m is – 11

The possible values of k are 3 and -3

Step-by-step explanation:

Given

Points: (-3,k) and (2,0)

Distance between them = √34

Required

Determine the value of k

The distance between two points is calculated as thus;

[tex]Distance = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Let

[tex](x_1,y_1) = (-3,k)[/tex]

[tex](x_2,y_2) = (2,0)[/tex]

Substitute these values in the given formula

[tex]Distance = \sqrt{(-3 - 2)^2 + (k - 0)^2}[/tex]

Evaluate the brackets

[tex]Distance = \sqrt{-5^2 + k^2}[/tex]

[tex]Distance = \sqrt{25 + k^2}[/tex]

Recall that Distance = √34

So; we have

[tex]\sqrt{34} = \sqrt{25 + k^2}[/tex]

Take square of both sides

[tex]34 = 25 + k^2[/tex]

Collect Like Terms

[tex]k^2 = 34 - 25[/tex]

[tex]k^2 = 9[/tex]

Take square root of both sides

[tex]k = \±3[/tex]

Hence, the possible values of k are 3 and -3

Explanation:

We'll use the intersecting chords theorem here

We multiply the pieces of each chord together and set the products equal to one another to help solve for x

TW*WU = CW*WV

x*2x = 6*10

2x^2 = 60

x^2 = 60/2

x^2 = 30

x = sqrt(30)

The value of x is √30. The correct option is D.

The measure of the angle created when two chords collide inside a circle is one-half the sum of the arcs intercepted by the angle and its vertical angle.

Use the intersecting chords theorem here. Multiply the pieces of each chord together and set the products equal to one another to help solve for x

Answer:

The correct option is;

AC and CD have the same length

Step-by-step explanation:

Given that the circle with center C, we have;

The length of AC extending from C to A being from the center to the circumference is the radial length of the smaller circle of center C.

Similarly, the length of the segment that extends from the center of the circle with center C to the circumference of the circle is the also the radial length of the smaller circle of center C.

Whereby the radial length of a circle is constant, then two radial lengths of the same circle are congruent and and circle radius AC is congruent to radius CD, which gives;

Length of AC = Length of CD or AC and CD have the same length.

Step-by-step explanation:

Lola has 12 times m total cakes. Adrian has 3 and a quarter left of cake. If they add theirs together they get 9. What is the value of m?

Answer: The sum of twelve times a number m and 3.4 is equal to 9.

Step-by-step explanation:

The givens are an algebraic expression 12m + 3.4 = 9. We need to put this in words.

So here is how we do it:

The sum of twelve times a number m and 3.4 is equal to 9.

OR you can say:

9 is equal to the sum of a number m twelve times and 3.4.

Answer:

The formula to find the voltage is:

[tex]v=\sqrt{P*R}[/tex]

And the voltage is 4 volts

Step-by-step explanation:

To get the equation of voltage you need to isolate v in one side of the equation. In order to do that, you need to remove the divisor/denominator and its square. How will you do that?

First, multiply both sides with R:

[tex]P*R=\frac{v^{2} }{R} *R[/tex]

That would result into removing the divisor R from the right side of the equation:

[tex]P*R=v^{2}[/tex]

Next, square-root both sides:

[tex]\sqrt{P*R} =\sqrt{v^{2} }[/tex]

That would result in removing the square of v from the right side of the equation:

[tex]\sqrt{P*R} =v[/tex]

Thus we get the equation, [tex]v=\sqrt{P*R}[/tex].

To find out the voltage, simply replace R with 32 and P with 0.5

[tex]v=\sqrt{0.5*32}[/tex]

[tex]r=\sqrt{16}[/tex]

[tex]r=4[/tex]

Thus, the voltage is 4 volts.

Answer:

Angle 1 = 39, Angle 2 = 78 , Angle 3 = 63

Step-by-step explanation:

78/2 = 39

(Angle 2/2 = Angle 1)

78 - 15 = 63

(Angle 2 - 15 = Angle 3)

39 + 78 + 63 = 180

(Angle 1 + Angle 2 + Angle 3 = 180)

Answer:

39°, 78°, 63°

Step-by-step explanation:

let ∠ 1 = x, then

∠ 2 = 2x ( twice the measure of ∠ 1 )

∠ 3 = 2x - 15 ( 15° less than ∠ 2 )

Sum the 3 angles and equate to 180

x + 2x + 2x - 15 = 180, that is

5x - 15 = 180 ( add 15 to both sides )

5x = 195 ( divide both sides by 5 )

x = 39

Thus

∠ 1 = 39°

∠ 2 = 2 × 39° = 78°

∠ 3 = 78° - 15 = 63°

Answer:

49.6 liters

Step-by-step explanation:

Let the number of water that the smaller chest be x liters. If the smaller chest can hold 4/5 of the water that the large chest can hold, then:

The amount of water held by small chest (x) = 4/5 × amount of water that can be held by large chest

x = 4/5 × 62 liters = 49.6 liters

This means that the small chest can hold up to 49.6 liters of water

Smaller chest can hold 49.6 liters.

The smaller chest holds 4/5 the amount of water that the larger chest can hold which is 62 liters.

The amount the smaller chest can hold is therefore:

= Amount of water large chest can hold x proportion of large chest that small chest can hold

= 62 x 4/5

= 248/5

= 49.6 liters

The smaller chest can therefore hold 49.6 liters.

Answer:

Step-by-step explanation:

x+6=x/2-2

solve the equation, x=-16

check:

-16+6=-10

-16/2=-8

-10-(-8)=-2

If the sum of a number and six is two less than half the same number then the number is -16.

Given,

The sum of a number and six is two less than half the same number

We will find the unknown number.

We have,

The sum of a number and six is two less than half the same number.

Let the unknown number be M.

Let us separate the given statement into parts:

- Sum of a number and six

This can be written as M + 6.

- is means equal sign "=".

- Two less than half the same number.

This can be written as (1/2)M - 2.

Now,

We can write as:

M + 6 = (1/2)M - 2

M - (1/2)M = -2 - 6

(1/2)M = -8

M = -8 x 2

M = -16

Thus the unknown number is -16.

We can also crosscheck:

M + 6 = (1/2)M - 2

-16 + 6 = (1/2)(-16) - 2

-10 = -8 -2

-10 = -10

Hence proved.

Answer:

897.23

Step-by-step explanation:

The decimal places start at the tenths:

00.tenths, hundredths, thousandths

So you would need to end up with only two numbers after the decimal.

To round, if a number is 4 or less, leave the next number as it is.

Ex: 2.32 → 2.3                    Rounding to the tenths

     78.614 → 78.6               Rounding to the tenths

If the number is 5 or higher, round up one number

EX: 37.76 → 37.8                Rounding to the tenths

      6.389 → 6.4                 Rounding to the tenths

Our number, 897.234, needs to be rounded to the hundredths place, so use the number to its right to determine the rounded value. The number 4 means that the hundredths place will remain the same, so the new value is:
