Answer:the number of sixth graders is 28
Step-by-step explanation:
Total number of students in the school band is 70. 40% are sixth graders. 20% are seventh graders and the rest are eighth graders. This means that the percentage of eighth graders is 100 - (40+20) = 100 - 60 = 40%
This means that the number of sixth graders would be 40% of the total number of students in the school band. It becomes
40/100 × 70 = 0.4×70 = 28
4>-x/4
Answer:
x>-16
Step-by-step explanation:
First
4> -x/4
switchsides
-x/4<4
then multipy both sides by 4
4(-x/4)<4*4
then multipy bothsides by -1 and reverse the inequality
(-x)(-1)> 16(-1)
Answer: yes choice B
Step-by-step explanation:
g(x) has -5 slope
y - g(-1) = -5(x +1)
y -5 = -5x -5
y = -5x
f(x) = xx/2 +2
Xx/2 +2= -5x
Xx/2 +5x +2 = 0
Xx + 10x +4 =0
Solutions: -5 + root(100 -16)/2
And -5 - root(84)/2
Both intersection look like in negative x values
Answer:
y= 15x+30
Step-by-step explanation:
Find slope using 2 points. Y intercept is where the graph intersects the y axis and you can see it intersects at 30

= -120 (Ans)
Answer:
-120
Step-by-step explanation:
lots of approaches here
suggest saying that there are 3 (odd) number of negative signs
so the answer is negative (-)
5*4 = 20
20*2 = 40
40*3 = 120
we determined that the answer has to be negative
-120
B.) y = -2
C.) x = -2
D.) x = -1
Answer:
A.) y = -1
Step-by-step explanation:
The equation of a horizontal line is ...
y = constant
To make that line go through the point (x, y) = (-2, -1), the constant must match the y-coordinate of the point: -1.
y = -1
Answer:
m = 3
Step-by-step explanation:
5m - 12 = m
subtract 5m from both sides
5m - 5m - 12 = m - 5m
simplify
-12 = -4m
divide both sides by -4
-12 / -4 = -4m / 4
simplify
3 = m
hope this helps :)
