Answer:
C
Step-by-step explanation:
With the filled in point means equal to but everything from there is less than. So the first part is equal to or less than 1. The second part is not equal with the open point so everything is greater than 1.
F(2)+g(4)
evaluate them seperately
f(2)=2+2=4
g(4)=10(4)-4
g(4)=40-4
g(4)=36
f(2)+g(4)=4+36=40
Answer:
x = (-28)/11
Step-by-step explanation:
Solve for x:
(55 x)/24 + 35/6 = 0
Put each term in (55 x)/24 + 35/6 over the common denominator 24: (55 x)/24 + 35/6 = (55 x)/24 + 140/24:
(55 x)/24 + 140/24 = 0
(55 x)/24 + 140/24 = (55 x + 140)/24:
(55 x + 140)/24 = 0
Multiply both sides of (55 x + 140)/24 = 0 by 24:
(24 (55 x + 140))/24 = 24×0
(24 (55 x + 140))/24 = 24/24×(55 x + 140) = 55 x + 140:
55 x + 140 = 24×0
0×24 = 0:
55 x + 140 = 0
Subtract 140 from both sides:
55 x + (140 - 140) = -140
140 - 140 = 0:
55 x = -140
Divide both sides of 55 x = -140 by 55:
(55 x)/55 = (-140)/55
55/55 = 1:
x = (-140)/55
The gcd of 140 and 55 is 5, so (-140)/55 = (-(5×28))/(5×11) = 5/5×(-28)/11 = (-28)/11:
Answer: x = (-28)/11
