1 answer:
Answer:
8:30 pm
Step-by-step explanation:
step 1
Decompose the numbers in prime factors
step 2
Find the LCM
The LCM of 30 min and 35 minutes will be given as
step 3
Adds 210 minutes to the starting time
First, converting 210 minutes to hours
Remember that
will need dividing 210 by 60
therefore
5:00 pm+3.5 h=8:30 pm

Determine the slope of the line
From the attachment, we have the following points
and
The slope m is then calculated using:
Substitute values for the x's and y's
<em>Hence, the slope is 0</em>
Answer:
Step-by-step explanation:
The given points are (-1,0) and (3,0) to find an equation of parabola. Notice that they say or the given points are x-intercepts, which means they make it easier for us to find an equation of parabola using these x-intercepts.
Quick Note:
- x-intercepts are simply the roots or solutions of quadratic equation, so if our root is x = -2 then we can write as (-2,0) and write back to x+2=0.
So what we are going to do is to write the roots’ equation back as
Our points or roots are given, therefore:
If x = -1 then x+1=0
If x = 3 then x-3=0
Then multiply x+1 with x-3 because if (x-1)(x+3)=0 then x-1=0 or x+3=0:
Convert 0 to y since we want to find a function:
Expand the expressions in and simplify to standard form:
Therefore, the equation is

Summary
If we are given the points and
with wideness of the graph or a-value = 1 then the parabola equation is:
