The answer (usually called the 'solution') is the one and only number that 'n' can be if that equation is a true statement. Here's a suggestion of a procedure you can use to find it:
<u>1.8 + 7n = 9.5 - 4n</u>
Add 4n to each side: 1.8 + 11n = 9.5
Subtract 1.8 from each side: 11n = 7.7
Divide each side by 11 : <em> n = 0.7</em>
Answer:
D
g(x) = 2 x²
Step-by-step explanation:
You are given a co-ordinate on g(x): (2,1). Plug this into the equaitons to see which one holds true.
A
g(x)=(0.5x)²?
2=(0.5(1))²?
2=0.25? NO
B
g(x)=(0.25x)²?
2=(0.25(1))²?
2=0.0625? NO
C
g(x)=0.5x²?
2=0.5(1²)?
2=0.5? NO
D
g(x)=2x²?
2=2(1²)?
2=2? YES
This could also be solved intuitively, since from the graph, you can see that the x values for g(x) are twice the x values for f(x), but the mathematical method above works too, and is useful if you find reading and assuming things from graphs difficult.
Answer:
Step-by-step explanation:
P(rolling 2 or 5)=2/6=1/3
Answer:
= -x^2 +x
Step-by-step explanation:
(x) = 1 - x^2
g(x) = 1-x,
(f-g)(x) = 1-x^2 - ( 1-x)
Distribute the minus sign
= 1-x^2 -1 +x
Combine like terms
= -x^2 +x
