Answer 2

A car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then  its average speed will be  [tex]56[/tex] miles per hour.

What is average speed ?

Average speed is speed is the total distance traveled by the car in a particular time of interval.

Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]

We have,

Distance [tex]=190[/tex] miles

Time[tex]= 3.4[/tex] hours

So, Using the above given formula,

Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]

                          [tex]=\frac{190}{3.4}[/tex]

                         [tex]=56[/tex] miles per hour

So, the average speed of car is [tex]56[/tex] miles per hour which is find out using the above given formula.

Hence, we can say that if a car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then  its average speed will be  [tex]56[/tex] miles per hour.

The points (2, 3) and (3, 6) fall on a particular line. What is its equation in slope-intercept
form?

Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

y=3x-3

Step-by-step explanation:

insert the first point into y=mx+b

3=2m+b

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

Do it again with the other point

6=3m+b

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

Now put both equations in a system of equations

3=2m+b

6=3m+b

solve for m and b

m=3 and b=-3

y=3x-3

m=slope

b=y-intercept

Can someone help me out with this question as I’m completely stuck

Answers

Answer:

Step-by-step explanation:

∠BEF = ∠ABE   {Alternate interior angle}

∠BEF = 60

∠EQR = ∠ BEF         {Corresponding angles}

∠EQR = 60

In ΔEQR

∠QER + ∠EQR + ∠ERQ = 180 {angle sum property}

80 + 60 +x = 180

140 + x = 180

          x = 180- 140

x = 40
