Answer:
Q1 d, Q2 c, Q3 d
Step-by-step explanation:
Q1
g(x)=-3x+1
g(x)=16 means that
-3x+1=16 subtract 1 from both sides
-3x=16-1 combine like terms and divide both sides by -3
x=-15/3=-5
Q2
g(x)=3x²+4x-1
g(2) means that x=2 so substitute
g(2)=3*2²+4*2-1=12+8-1=19
Q3
domain are the x values
range are the y values
Answer:
52:3
Step-by-step explanation:
divide 260 by 5 and 15 by 5
260 divided by 5 = 53
15 divided by 5 = 3
260:15 = 52:3
Answer:
247,085 doctors in total
Step-by-step explanation:
55,100 = 22.3℅ ÷22.3
2,471 = 1℅
2471.85x100 = 247,085 doctors
To check I'll do 247,085÷100 = 2,470.85 = 1℅
2,470.85 × 22.3 = 55,099.955 which would round up to 51,000.
Answer:
If this is the problem
g(t) = t2 - 3t and h(t) = 3t - 4
g[ h(t) ] = (3t-4)2 - 3 (3t-4)
g[ h(t) ] = 9t2 - 24t + 16 - 9t + 12
g[ h(t) ] = 9t2 - 33t + 28
