Hi there!
To find f(1), plug in x=1 into the equation
f(1) = -4(1) + 7
= -4 + 7
= 3
That's your answer.
Have an awesome day! :)

Answer:
Step-by-step explanation:
Let the smaller number be 
. Since they are consecutive even numbers, the larger number can be represented by 
.
Therefore, we have the following equation:
Thus, the larger number is 
Answer:
1/3 · -x < 12
Step-by-step explanation:
one third meaning 1/3
"of" meaning multiplication
"opposite" of a "number" meaning negative x
Less than 12 meaning > 12
Answer:
The calculated dollar-weighted rate of return, Y = -25%.
Step-by-step explanation:
The time-weighted rate of return is 0%
Therefore, (12/10)*( X/(12 + X)) = 1
12X = 120 + 10X -> X = 60
The dollar-weighted rate of return,Y is calculated below as:
Y = (X-(10 + X))/(1*10+X/2)
Y = (60-(10+60))/(1*10+60/2)
Y = (60 - 70)/(10+30)
Y= -10/40
Y = -25%
Therefore, the calculated dollar-weighted rate of return, Y = -25%.
In a division problem, ...
... dividend / divisor = quotient
Multiplying both sides of this equation by "divisor", we get ...
... dividend = quotient × divisor . . . . . . . . the desired relationship
The for dividend = 1/8, divisor = 6, and quotient = 1/48, this becomes ...
... 1/8 = 1/48 × 6
... 1/8 = 6/48 = 1/8 . . . . . the given values are consistent
