y varies directly with x. y is 84 when x is 16. What is the constant of proportionality? (Write answer as improper fraction...Remember to reduce!)
Answer: 5 1/4
Step-by-step explanation:
We use the formula for direct proportion to solve the question since we are informed that y varies directly with x and that y is 84 when x is 16.
The formula will be:
y = kx
where,
y = 84
x = 16
We then slot the values into the formula
y = kx
84 = 16k
k = 84/16
k = 5 1/4
The constant of proportionality is 5 1/4
8. Which of the following is the 43rd term of the arithmetic sequence 3,0-3, ...?
A-117
B 120
C. -123
D. -126
Answer:
C
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 3 and d = a₂ - a₁ = 0 - 3 = - 3 , thus
a₄₃ = 3 + (42 × - 3) = 3 - 126 = - 123 → C
Answer:
C. -123.
Step-by-step explanation:
nth term = a1 + d(n - 1)
43rd term = 3 + -3(43-1)
= 3 - 126
= -123.

The solutions to the equation f(x) = g(x) are -2 and 1. If f and g are graphed on the same coordinate plane, which statement must be true?
A.the functions will intersect at x = -2 and x=1
B. The functions will intersect at y = -2 and y = 1
C. Both functions will have y-intercepts at -2 and 1
D. Both functions will have x- intercepts at -2 and 1
Answer:
c
they will both have to intersect since you have a negative and positive number. Hope it helps.
Step-by-step explanation:
The functions will intersect at y = -2 and y = 1. Option B is correct.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The solutions to the equation f(x) = g(x) are -2 and 1.
Solution of the equation state the definition that, when two functions intersect each other, is the solution of the functions. So as mentioned both functions as f(x) = g(x) gives y = -2 and y = 1, implying that The functions will intersect at y = -2 and y = 1.
