Answer:
zero
Step-by-step explanation:
The class is made up of male and female students.
"A drama class has a total of 26 students"
f + m = 26
"The number of females is 16 less than the number of males"
f = m - 16
Substitute the second equation into the first.
m - 16 + m = 26
- combine like terms -
2m - 16 = 26
- add 16 to both sides -
2m = 42
- divide by 2 -
m = 21
Now substitute that answer into either equation
f + 21 = 26
- subtract both sides by 21 -
f = 5
Remember that whatever you do to one side, you have to do to the other
Answer:
38.4
38.4 is 48% of 80
Step-by-step explanation:
What is 48% of 80?
Y is 48% of 80
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 48% * 80
Converting percent to decimal:
p = 48%/100 = 0.48
Y = 0.48 * 80
Y = 38.4
F(x) = a(x - h)2 + k
f(x) = a(x + 2)2 - 7
(0,-3)
-3 = a(0 + 2)2 - 7
4 = a(2)2
4 = 4
1 = a
f(x) = 1(x + 2)2 - 7 = x2 + 4x - 3
