Y-1/2 <span>≤ -3/2 This is the answer</span>
Answer:
33
Step-by-step explanation: It might not be 33 but i think it is because if you look at the other side it says 33 and their located at the same spot so they might be saying that you need to find the other angle which is already displayed but just on another side. So therefore, i think it is 33. Sorry if its confusing B(
I'm going to show you two ways to do it.
Way #1 is the slogging way.
Way #2 is the clever way.
Way #1:
' One hundred percent ' means ALL of something.
ALL of the students in the school is the same as 100% of them.
If 10% are absent, then 90% are present.
90% means 0.9 .
1620 students = 90% of the school.
1620 = 0.9 x school total
Divide each side by 0.9: 1620/0.9 = total school
1800 = total school
How many were absent ?
10% of them.
10% means 0.10 .
0.10 x 1800 = 180 students absent .

Way #2:
' One hundred percent ' means ALL of something.
ALL of the students in the school is the same as 100% of them.
==> If 10% are absent, then 90% are present.
==> The number of students present is 9 times the number who are absent.
1620 = 9 x the number absent
Divide each side by 9 : 1620 / 9 = the number absent
1620 / 9 = 180 absent .
Answer:
x = 
Step-by-step explanation:
Step 1: Solve
We can divide 3 from both sides to get "x" by itself

Therefore x = 
To find the turning point, or vertex, of this parabola, we need to work out the values of the coefficients b and c.
We are given two different solutions of the equation.
First, (2, 0).

Second, (0, 14).

So we have a value (14) for c. We can substitute that into our first equation to find b.

We can now plug in our values for b and c into the equation to get its standard form.

To find the vertex, we can convert this equation to vertex form

by completing the square.




Thus, the vertex is (4.5, –6.25).
We can confirm the solution graphically (see attachment).
