I think the 4 wasn't distributed correctly. it should be one of the first steps.
Answer:
Answer: the equivalent form of 6(2x+3x+10) are 12x+18x + 60 and 30x+60.
Hope this helps
Ms. Morris can divide the class into 5.
5 times 5 equal 25.
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = - 2x² + 4x - 2
To find the y- intercept set x = 0
f(0) = 0 + 0 - 2 = - 2 ← y- intercept
The equation of the axis of symmetry is of the form x = c
where c is the value of the x- coordinate the line goes through.
Given the equation in standard form
with a = - 2, b = 4 then the axis of symmetry is
x = -
= -
= 1
Equation of axis of symmetry is x = 1
Answer:
33 students
Step-by-step explanation:
Since there aren’t going to be fractions of people, you can just count up using the whole numbers in the ratio (4 on the left, 7 on the right) and then check if the sum is between 24 and 40.
4:7 = 11 students (not enough)
8:14 = 22 students (not enough)
12:21 = 33 students (fits criteria)
12 boys, 21 girls, for a total of 33 students.
