Answer:
ax^2 + bx + c = 0
Here is a specific example:
5x^2 - 3x + 2 = 0
In other words:
You have zero on the right.
On the left, you have the powers of “x” in descending order.
Answer:
<em>Hi</em><em> </em><em>there</em><em>!</em><em>!</em>
<em>The</em><em> </em><em>answer</em><em> </em><em>would be</em><em> </em><em>x</em><em>=</em><em>2</em><em>0</em><em> </em><em>and</em><em> </em><em>y</em><em>=</em><em> </em><em>1</em><em>0</em><em> </em><em>root</em><em> </em><em> </em><em>3</em><em> </em><em>or</em><em> </em><em>on</em><em> </em><em>decimal</em><em> </em><em>it's</em><em> </em><em>1</em><em>7</em><em>.</em><em>3</em><em>2</em><em>.</em>
<em>explanation</em><em> </em><em>look</em><em> </em><em>in</em><em> </em><em>picture</em><em>,</em><em> </em><em>alright</em><em>. </em>
<em><u>I</u></em><em><u> </u></em><em><u>hope</u></em><em><u> </u></em><em><u>it will</u></em><em><u> </u></em><em><u>help u</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em>
let X be number of students
and y be total cost
when 30 students (30,X)where at the gym it's costs 200 (y,200)
=that is (X,y)=(30,200)
when 70 students where at the gym
=(X,y)= (70,330)
now we find the slope
M=y2-y1/x2-x1
= 330-200/70-30
= 100/40
= 2.5=3
now
Y=Mx+b
Y=2x+b
we need to find the value of b
so,we substrate for X and Y
X=30,200
200=2(30)+b
re-arrange
B+60=200
B=200-60
=140
y=2x+140
For the other questions, I can look at the equation I got. The y-intercept (b value) is $200. That means that we are adding $200 on to the price all the time. That's the price for the empty bus. The 2x means to multiply the number of people by two and add this to the $120. So each person is $2.
hope it's helpful
and please I really need brainliest, thanks
The area of the figure is 28 yd^2
The answer is 4.953 I don't understand how you would use a table sorry.
