Answer:
Option C.
Step-by-step explanation:
If k<0, the function g(x) = f(x) + k represents the function f(x) shifted k units downwards.
In this case, given that k=-3 (k<0). The graph was shifted 3 units down. Therefore, the correct option is Option C.
Ratio of boys to girls = 1 : 3
Unknown constant = x
x + 3x = 24
4x = 24
x = 6
No. of girls = 3 x 6 = 18
Answer:
v = 18
Step-by-step explanation:
26 = 8 + v
v = 26 - 8
v = 18
4(x+5)=9x + 4x - 34 (given)
4x + 20 = 9x + 4x - 34 (distributive property)
4x + 20 = 13x - 34 (combine like terms)
20 = 9x - 34 (subtraction property of equality)
54 = 9x (subtraction property of equality)
x=6 (division property of equality)
Answer:
x=2
Step-by-step explanation:
=>30x = 30+30
=>30x = 60
=>x= 60/30
=>x=2
