What are the coordinates of point B?
zaharov [31]

Point a is at (-2,4) => (x1,y1)

Midpoint is (2.5, 3.5) => (a,b)

Point B is (x2, y2)

To find midpoint we use formula

(a=\frac{x_1+x_2}{2} , b= \frac{y_1+y_2}{2})

a= 2.5, b= 3.5, x1= -2  and y1= 4

Plug in all the values and findout x2, y2

(2.5=\frac{-2+x_2}{2} , 3.5= \frac{4+y_2}{2})

multiply 2 on both sides to remove fraction

(5 = -2+x2 , 7 = 4+ y2)

5 = -2+x2, so x2= 7

7 = 4+ y2, so y2= 3

The point B is ( 7, 3)

You bike for 2 hours at a speed no faster than 17.6 mph. Write an inequality that represents the possible number of miles you bi
Whitepunk [10]
Total no. of hours you spent biking = 2 hours
the speed at which you rode your bike ≤ 17.6 mph
Now,
We have,
speed =  \frac{distance}{time}

17.6 =  \frac{distance}{2}

17.6 *2=  distance

35.2=distance

So, you for given conditions, you can't travel more then 35.3 miles

So, the inequality for the given circumstances is:
x ≤ 35.2

An equation that is satisfied for every value of the variable for which both sides are defined
mote1985 [20]
<span>An equation that is satisfied for every value of the variable for which both sides are defined is called an identity.

For example:
Given the equation
3x + 4 = x + 2(x + 2)

Notice that for any value of x you use, the equation is true.

Thus, this type of equation is called an identity.
