Annie must of traveled for 10 hours and Brian must have traveled 10 hours to.

Use the distributive property:

5*b+5*2+b=20

5b+10+b=20.

Combine like terms:

6b+10=20.

Subtract 10 from both sides:

6b+10-10=20-10

6b=10.

Divide both sides by 6:

6b/6=10/6

b=5/3=1 2/3.

Brian travels 1 2/3 hours. This means Annie travels

5(1 2/3+2)=5(3 2/3)=5(11/3)=55/3=18 1/3 hours.

Hope this helps!

Answer:

the possible line of best fit equation is;

y = 10x + 24

Step-by-step explanation:

Here, we want to get the approximate line of best fit

Mathematically, we have the general line of best fit as

y = mx + b

where m is the slope and b is the y-intercept

By joining the given lines, we can see that the y-intercept values fall a little below 30

This means that the possible y-intercept value is 24

Now, to get the slope value, we select any two points and use the slope equation

We can have (3,50) and (6,80)

Using the slope equation;

m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10

The equation is thus;

y = 10x + 24

Representing algebraic relationships in tables and graph. Graph each equation y=x+3
KatRina [158]

Answer:

Step-by-step explanation:

To graph this equation, start by plugging in different numbers for X and solve for Y.

For example: When x=0, y=0+3 ⇒ the coordinate is (0,3)

When x=1, y=1+3 ⇒ (1,4)

If you do this enough times, dotting each new coordinate then connecting them in a straight line, you will get your graph.
