Answer:

No

Step-by-step explanation:

If you plug in the coordinates (4,2) to y=x-2 it will give you 2=2 which is rite, but if you plug it in to y=3x+4 it will give you 2=16 which isn't rite.

A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2,
Oksanka [162]

Answer:

A. one  B. (3, 4)

Step-by-step explanation:

1. A good graph can answer both parts (see attached image).

2. Write equations for the two lines and find a simultaneous solution.

Line A:  Slope from (2, 6) to (5, 0) is m=\frac{6-0}{2-5}=\frac{6}{-3}=-2

Using point-slope form y-y_1=m(x-x_1)

y-6=-2(x-2)\\y-6=-2x+4\\y=-2x+10

Line B:  Slopt from (6, 6) to (0, 2) is m=\frac{6-2}{6-0}=\frac{2}{3}

Using point-slope form, the equation for Line B is

y-2=\frac{2}{3}(x-0)\\y=\frac{2}{3}x+2

To find the simultaneous solution, set the <em>y's </em>equal.

-2x+10=\frac{2}{3}x+2\\-6x+30=2x+6\\-8x=-24\\x=3

Find <em>y</em> using either equation to get y = 4.

mia hired a moving company, it charged 500$ for service mia give them a 16% tip.How much did she tip the movers,
snow_tiger [21]

Answer: 80 dollars

Step-by-step explanation:

You can find a percentage with one of two ways.

For hundreds like this, oftentimes it's quicker and more simple to think of it as just 100. The proportion from 100 to 500 is just 5.  16% of 100 is 16. So, multiply 16 * 5. You would get 80.

The second method is you can use 0.16 * 500. It's the more conventional method, and you get 80, like the last method.

Explain: how would you model 5 x 2/3
ELEN [110]
Well as you can see 5 x 2/3= 3 1/3 there is 7 steps to figure it out

1. set up the problem
5 x 2/3

2. put a 1 on 5 to make it a fraction
5/1 x 2/3

3. multiply and divide
(5 x 2) / (1/3)

4. find out the answer
10/3

5. turn the answer into a mixed fraction
10 divided by 3= 3.1 3 stays the same you don't need to say 1

6. it equals
3 1/3

7. so the answer is
3 1/3
