Answer:

$\begin{array}{c|c}x&y\\-2&13\\-1&9\\0&5\\1&1\\2&-3\end{array}$

Step-by-step explanation:

Put x = -2, x = -1, ... , x = 2 to the equation of the function y = -4x + 5 and calculate the values of y:

for x = -2

y = -4(-2) + 5 = 8 + 5 = 13

for x = -1

y = -4(-1) + 5 = 4 + 5 = 9

for x = 0

y = -4(0) + 5 = 0 + 5 = 5

for x = 1

y = -4(1) + 5 = -4 + 5 = 1

for x = 2

y = -4(2) + 5 = -8 + 5 = -3

Just put the values given for x in the equation to find y

-4(-2)+5=13

-4(-1)+5=9

-4(0)+5=5

-4(1)+5=1

-4(2)+5=-3

A ferry traveled 1/6 of the distance between two ports in 3/7 hour at this rate what fraction of the distance between the two po

Masja [62]

First, we determine the speed of the ferry by dividing the distance by the time it took to cover that certain distance.
speed = (1/6) / (3/7)
speed = 7/18
Then, the distance it will travel for an hour is calculated through the procedure below.
distance = (7/18hour) x (1 hour)
distance = 7/18
Therefore, after an hour, the ferry will be able to travel 7/18 of the distance between two ports.

Alvin is 9 years older than Elga. The sum of their ages is 89. What is Elga's age?

Mekhanik [1.2K]

Answer:

Alvin: 49

Elga: 40

Step-by-step explanation:

The equation is 89 = x + (x-9).
Remove the parenthesis and combine the like terms. 89 = 2x - 9
Add 9 on both sides. 98 = 2x
Divide by 2 on both sides. x = 49
49 is the age of Alvin. (49-9) 40 is the age of Elga.
