y - 12/3 = 1/3x + 2/3

y = 1/3x + 14/3

Answer:

y = - 2(x - 1)² + 18

Step-by-step explanation:

- 2x² + 4x + 16 ← factor out - 2 from the first 2 terms

= - 2(x² - 2x) + 16

using the method of completing the square

add/subtract ( half the coefficient of the x- term)² to x² - 2x

= - 2(x² + 2(- 1)x + 1 - 1) + 16

= - 2(x - 1)² + 2 + 16

= - 2(x - 1)² + 18 ← in vertex form

Hope you found this answer very useful

Simplifying

9x + -17 = 4x + 28

Reorder the terms:

-17 + 9x = 4x + 28

Reorder the terms:

-17 + 9x = 28 + 4x

Solving

-17 + 9x = 28 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

-17 + 9x + -4x = 28 + 4x + -4x

Combine like terms: 9x + -4x = 5x

-17 + 5x = 28 + 4x + -4x

Combine like terms: 4x + -4x = 0

-17 + 5x = 28 + 0

-17 + 5x = 28

Add '17' to each side of the equation.

-17 + 17 + 5x = 28 + 17

Combine like terms: -17 + 17 = 0

0 + 5x = 28 + 17

5x = 28 + 17

Combine like terms: 28 + 17 = 45

5x = 45

Divide each side by '5'.

x = 9

Simplifying

x = 9

Step-by-step explanation:

let's be more detailed than the other answer :

the perimeter is the sum of all sides of an object. in case of a triangle, well, that is the sum of all 3 sides.

so,

25 = x + (x-5) + (x+3) = x + x - 5 + x + 3 = 3x - 2

27 = 3x

x = 9

so, the sides are

x = 9 cm

(x-5) = 9 - 5 = 4 cm

(x+3) = 9 + 3 = 12 cm

Answer:

14

Step-by-step explanation:

We can find the sum of these numbers by adding them together.

The cumulative rule of addition lets us add numbers together in any order we want.

So, for 2 + 3 + 4 + 5 …

2 + 3 = 5

So now we have 5 + 4 + 5

5 + 4 = 9

Now we have 9 + 5

And 9 + 5 = 14

So, your answer is 14

Answer:

1400

Step-by-step explanation:

67 rounds to 70 because 7 is bigger than 5 so it rounds up. 23 rounds down since 3 is smaller than 5.

So, 70x20=1400

Answer:

6 Miles

Step-by-step explanation:

What do we know: Linda hiked 10 miles last weekend, and she plans to walk 3/5ths of that next weekend.

Thus, we take 10 and multiply it by 3/5.

To understand it all better, let's write the equation like this, X will be the number of miles Linda plans to hike next weekend.

[tex]\frac{10}{1}[/tex]×[tex]\frac{3}{5}[/tex] = [tex]\frac{30}{5}[/tex]

Afterwards we can simplify like so, factoring 5 from both the numerator and the denominator:

[tex]\frac{5(6)}{5(1)}[/tex]

The 5's in the numerator and denominator cancel out, leaving us with:

[tex]\frac{6}{1}[/tex]

Or in simpler terms 6. Thus we can know that Linda will hike 6 miles next weekend.

Answer:

by 6

Step-by-step explanation:

Isolate x for x + 2y= 11: x= 11- 2y

Substitute x =11 -2y

6(11 - 2y) + 4y = 34|

Simplify

[66 -8y= 34]

Isolate y for 66 - 8y= 34: y =4

For x = 11 - 2y

Substitute y = 4

X= 11-2 x 4

Simplify

X=3

The solutions to the system of equations are:

X=3,y=4

Answer:

x = 6

Step-by-step explanation:

To find x we set up an  equation as so:

[tex]\frac{4.5}{x} =\frac{6}{8}[/tex]

Then we solve by multiplying 4.5 by 8 and 6 by x

[tex]6x=36[/tex]    Solve for x

[tex]\frac{6x}{6} =\frac{36}{6}[/tex]    x = 6

To check our answer when we substitute x or 6 we divide to make sure both sides equal the same number

[tex]\frac{4.5}{6} =\frac{6}{8}[/tex]    when divided both equals 0.75

Answer:

[tex]1\frac{1}{5}[/tex]

Step-by-step explanation:

6/5

= 1 1/5

Answer:

[tex]1\frac{1}{5}[/tex]

Step-by-step explanation:

First, we do 6 / 5 = 1.2. We do this because we are sharing 6 cups with 5 friends - we are dividing 6 cups between 5 friends.

So, each friend will get 1.2 cups. But, the question is asking for a fraction. 0.2 is the same as [tex]\frac{1}{5}[/tex], so each person will get [tex]1\frac{1}{5}[/tex]

Alternatively, you could do [tex]\frac{6}{5} = 1\frac{1}{5}[/tex]

Hope this makes sense.

Answer:

(1, 2)

Step-by-step explanation:

Hi there!

We are given two points - (4, 7) and (-2, -3)

We want to find the midpoint between these two points

The midpoint can be found using the formula [tex](\frac{x_1 + x_2}{2}, \frac{y_1+y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything we need to find the midpoint, but let's label the values of the points to avoid any confusion & mistakes

[tex]x_1=4\\y_1=7\\x_2=-2\\y_2=-3[/tex]

Now substitute into the formula

[tex](\frac{x_1 + x_2}{2}, \frac{y_1+y_2}{2})[/tex]

[tex](\frac{4+ -2 }{2}, \frac{7+-3}{2})[/tex]

The pluses can be replaced with minus signs:

[tex](\frac{4 -2 }{2}, \frac{7-3}{2})[/tex]

Now subtract

[tex](\frac{2 }{2}, \frac{4}{2})[/tex]

Divide

(1,2)

The midpoint is (1, 2)

Thus, the diameter of the circle is 12 miles

Answer:

42$

Step-by-step explanation:

Hope it helps :)

The area and the circumference of the circle are 530.93 square ft and 81.68 ft. If fertilizer will be applied to the lawn. Then the area is used. If the lawn will be surrounded by tape. Then the circumference is used.

It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

The figure below shows a circular lawn. Its diameter is 26 ft.

Then the area of the circle will be

[tex]\rm A = \dfrac{\pi }{4} d^2\\\\A = \dfrac{\pi }{4} \times 26^2\\\\A = 530.93 \ \ ft^2[/tex]

Then the circumference of the circle will be

Circumference = π d

Circumference = π × 26

Circumference = 81.68 ft

If fertilizer will be applied to the lawn. Then the area is used.

If the lawn will be surrounded by tape. Then the circumference is used.
