Answer:
20
Step-by-step explanation:
Why? because 100$ in 5 days is he spent the same much each day then it's 20 because 20 x 5=100
20 x 1=20
20 x 2=40
20 x 3=60
20 x 4=80
20 x 5=100
Answer:
<h2>
</h2>
Step-by-step explanation:
s = πrl + πr²
First move πr² to the left side of the equation
We have
πrl = s - πr²
Divide both sides by πr to make l stand alone
That's
<h3>
</h3>
We have the final answer as
<h3>
</h3>
Hope this helps you
Answer:
y1= 0, y2= 5/3
Step-by-step explanation:
Remove the parentheses and multiply
then cancel the equal terms
collect the lie terms
move the variables to one side
divide both sides by two
split into possible cases
then solve the equation to get
y= 0 and
y= 5/3
The first equation
6x^2 -18x-24=0
-the graph opens up
6(x^2 -3x -4)=0
6(x^2 -3x +9/4-4-9/4)=0
6(x-3/2)-25x6/4=
6(x-3/2)-75/2
-Vertex is at (3/2, -75/2)
-Axis of symmetry is x=3/2
Second equation
3r^2 -16r -12=0
-the graph opens up
...
9x-3+69-3x=0
6x+66=0
6x=-66
X=-11
