Answer:
The y-intercept is y = 2
Step-by-step explanation:
A linear function has the following format:

In which m is the slope and b is the y-intercept, which is the value of y when x = 0.
We are given these three points:
(-28, -54)
(-21, -40)
(-14, -26)
We use two of them to build a system, to find values for m and b.
(-28, -54)
This means that when 
So




(-21, -40)
This means that when 
So








The y-intercept is y = 2
Answer:
<h2>At the 7th bounce, the ball reached 2.3 feet height.</h2>
Step-by-step explanation:
The given expression is

This exponential function represents the movement of a bouncing ball after being dropped.
represents the bounce number.
So, at 7th bounce means
, replacing this value in the function, we have

Therefore, at the 7th bounce, the ball reached 2.3 feet height.
Hello! In order to find a linear function without graphing it, we can see if the x-values (domain) has more than one value of y (range) out of this set of ordered pairs. Those ordered pairs represent a linear function, because each x-value does not have more than 1 y-value. Therefore, those points satisfies a function.
Answer:
1.) 7x+5y
2.)-19m+14r
3.)22b+40c
4.)10x+25
5.)7m+7
Step-by-step explanation:
ez
4³ x 4^-6 you have to add the exponents, so it is <u>4 to the power of -3. </u> Hope this helps!
