Answer:

[tex]x=\frac{1}{7}y+\frac{3}{7}[/tex]

Step-by-step explanation:

[tex]y=7x-3[/tex]

[tex]7x-3=y[/tex]

[tex]7x-3+3=y+3[/tex]

[tex]\frac{7x}{7}= \frac{y+3}{7}[/tex]

[tex]x=\frac{1}{4}y+\frac{3}{7}[/tex]

Answer:

[tex]A\approx1608.7\text{ yards}^2[/tex]

Step-by-step explanation:

We can use the alternate formula for the area of a triangle:

[tex]A=\frac{1}{2}ab\sin(C)[/tex]

Where a and b are the side lengths, and C is the angle between the side lengths.

We know that one side length is 60 and the other is 70.

The angle between them is 50°.

So, substitute 60 for a, 70 for b, and 50° for C. This yields:

[tex]A=\frac{1}{2}(60)(70)\sin(50)[/tex]

Evaluate using a calculator. Make sure you’re in Degrees Mode.

Therefore, the approximate area is:

[tex]A\approx1608.7\text{ yards}^2[/tex]

Answer:

4 + -13 = -9

Answer:

[tex]26M + 56D = 2278[/tex] ---- equation 1

[tex]M = 3D[/tex] ---- equation 2

A microscope costs S51 and a dissection kit costs S17

Step-by-step explanation:

Given

Represent microscope with M and Dissection kits with D

Cost:

[tex]M = 3D[/tex]

[tex]Total = 2278[/tex]

Required

Represent as an equation:

To do this, we represent the equation in terms of cost and quantity

In terms of cost, we have:

[tex]26M + 56D = 2278[/tex] ---- equation 1

and

[tex]M = 3D[/tex] ---- equation 2

Substitute 3D for M in equation 1

[tex]26*3D + 56D = 2278[/tex]

[tex]78D + 56D = 2278[/tex]

[tex]134D = 2278[/tex]

Divide both sides by 134

[tex]D = \frac{2278}{134}[/tex]

[tex]D = 17[/tex]

Substitute 17 for D in [tex]M = 3D[/tex]

[tex]M = 3 * 17[/tex]

[tex]M = 51[/tex]

Hence:

A microscope costs S51 and a dissection kit costs S17

Answer:

-0.5

Step-by-step explanation:

Answer:

1/4, 2/5, 1/2, 3/5

Step-by-step explanation:

1/4=0.25

3/5=0.6

2/5=0.4

1/2=0.5

Answer:

[least]  1/4, 2/5 , 1/2, 3/5 [greatest]

Step-by-step explanation:

Well lets find out LCD (least common denominator) for 4,5 and 2

LCD-20

12/20 =used to be 3/5

5/20=used to be 1/4

10/20=used to be 1/2

8/20=used to be 2/5

Now that you know all of them and have common denominator lets order!!

[least]  1/4, 2/5 , 1/2, 3/5 [greatest]

Hope this helps :3

(2 , 0)  ; (0, 1)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\[/tex]

          [tex]= \frac{1-0}{0-2}\\\\=\frac{1}{-2}\\\\\\=\frac{-1}{2}[/tex]

m = -1/2 ; (2 , 0)

Equation of the line : y - y1 = m(x - x1)

                                  [tex]y - 0 = \frac{-1}{2}(x-2)\\\\ y = \frac{-1}{2}x - 2*\frac{-1}{2}\\\\\\ y = \frac{-1}{2}x+1[/tex]

slope = (-1/2)

y - intercept = 1

Step-by-step explanation:

Answer:

one solution is your answer to the question

Answer:

Perform the indicated multiplication: 2 - 3x - 12 = 9 - 3x

Gather all the x terms on one side and all the constants on the other:

-3x + 3x = 9 + 12 - 2, or 0 = 19

since this is never true, 2 - 3x - 12 = 9 - 3x has no solution.

Answer:

Y=-2x+9

Step-by-step explanation:

The first thing is to know the formula which is Y÷x

Then... The line (1,7)use the coordinates Y and X so it will be as follows... Label 1 and 7 as x, y

So it will be Y-7÷X-1 = the gradient which is - 2

So multiply both sides by X-1

So it will be Y-7=2x+2 again be careful because a negative number multiplied by another negative will give you a positive sign

Remember Y-7....... Take 7 to the other side so it will be a positive...... Then work out the integers

I'm assuming you're being taught how to work with negative intervals in algebra? Don't worry, that's why you're practising with temperature. Instead of asking online, try using the progress your teacher taught you. If you have notes, look back at them. Practise makes perfect :)
