Draw a coordinate plane on your paper and graph the following using intercepts. x+2y = 6 2x-y= 4​

Answer:

3 x − y = − 13

Step-by-step explanation:

Any equation that relates the first power of x to the first power of y produces a straight line on an x-y graph. The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept. Converting from slope intercept form to standard form takes little more than basic arithmetic.

TLDR:

To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.

Answer:

3x - y = -13

Step-by-step explanation:

y = mx + b

(This is the slope intercept form)

We want to change it to standard form, which is:

Ax + By = C

We want to rearrange as many of the numbers as we can, without actually changing the problem!

Ax = 3x

By = y

C = 13

So we must move the numbers from one side to another.

Whatever you do to one side, you do to the other.

y = 3x + 13

-3x + y = -3x - y

--------------------

-3x + y = 13

Since we can't have our "Ax" as a negative multiply everything by -1

-1[-3x + y = 13]

3x - y = -13

That is your answer.

Answer:

dive the cost by the number of bags for each dot:

4 / 1 = 4

8 / 2 = 4

12 / 3 = 4

This means each bag cost $4

The equation would be Y = 4X, because you would multiply each bag bought (X) by $4 to get the total cost (Y).

Answer:

B. 1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles.  

Step-by-step explanation:

If x represents the number of miles driven by the taxi  

Then, amount charged= $ (2.50+1.95x)  

Isaac was charged $27.46  

2.50+1.95x = 27.46  

Subtracting both sides by 2.50, we get  

1.95x= 24.96  

Dividing both sides by 1.95, we get  

x=12.8

The linear equation will be 1.95x + 2.50 = 27.46

Amount charged to pick up passenger = $2.50 to pick up a passenger

Amount charged per mile = $1.95 per mile

Since Isaac was charged $27.46, then the equation will be:

2.50 + 1.95(x) = 27.46

2.50 + 1.95x = 27.46

Therefore, the linear equation will be 1.95x + 2.50 = 27.46

The turtle's rate in miles per hour is 1/5 miles/hr.

Given is that a turtle traveled 1/10 miles in 1/2 hour.

We can write the rate as -

{R} = (1/10)/(1/2)

{R} = (1/10) x 2

{R} = 1/5 miles/hr

Therefore, the turtle's rate in miles per hour is 1/5 miles/hr.

C=6.4ft

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + 5^2 = c^2

4 + 4 = 16

5 + 5 = 25

16 + 25 = c^2

41 = c^2

Now you will need to find the square root of 41 which gives you 6.40 and you just round to nearest tenth..

Pablo Used the Commutative property to Reorder the terms. Pablo then Combined all his like terms. Pablo then Divided 21 by 3x to get 3(7+x). Pablo then subtracted 7 from 13. He got x = 6

Pablo did his math wrong.

Karla Did her work correctly. Karla used the commutative property to reorder the terms. She then combined her like terms. She subtracted 21 from itself and 39, leaving 3x and 18 on different sides of the equal sign. She divided 3x by 3 which equals x and 18 by 3 which equals Karla is correct.

Answer:

d

Step-by-step explanation:

because it is a one to one relation

The answer is d., its the only one that isnt x to 2 y's or y to 2 x's

Answer:

D.

Step-by-step explanation:

The equation given takes the point-slope form which is, [tex] y - b = m(x - a) [/tex]. Where,

(a, b) = (x, y) coordinates of a point on the line.

m = slope of the line .

To find which graph has a line equation of [tex] y - 2 = 3(x - 1) [/tex], look for the points which will give you something almost exactly as the equation if you substitute their values into [tex] y - b = m(x - a) [/tex].

Let's consider option D.

We have a given point (1, 2). a = 1, b = 2.

Substitute these into [tex] y - b = m(x - a) [/tex]

We have:

[tex] y - (2) = m(x - (1)) [/tex]

[tex] y - 2 = m(x - 1) [/tex]

As you can see, this looks almost exactly as

[tex] y - 2 = 3(x - 1) [/tex].

If you want to be certain that option D is the answer, find m by using the coordinates of any other point on the line and plug into [tex] y - 2 = m(x - 1) [/tex] to find m:

In graph D, let's take the points (0, -1)

[tex] -1 - 2 = m(0 - 1) [/tex]

[tex] -3 = m(-1) [/tex]

[tex] -3 = -m [/tex]

Divide both sides by -1

3 = m

m = 3.

Therefore, option D is the graph of the line [tex] y - 2 = 3(x - 1) [/tex].

Answer:

kshs 6,480,000

Step-by-step explanation:

Since, kshs 240,000 represent the 3% of the car price, you can use a rule of three to calculate the amount that represents 100%:

240,000 →   3%

     x       →  100%

x=(240,000*100)/3

x=8,000,000

So, the price of the car is kshs 8,000,000 and you can calculate the 16% of this, to find the amount that the dealer had to pay as government V.A.T:

8,000,000*16%=1.280.000

Now, you can subtract the comission and the government VAT from the car price:

8,000,000-240,000-1,280,000=6,480,000

According to this, the answer is that the dealer remained with kshs 6,480,000 from the sale of the car.
