Sergeeva-Olga [200]3 years ago
8 0

Answer:

5

Step-by-step explanation:

given that x and y are proportional, they can be expressed as y = rx, where r is the proportionality constant. Thus, we can solve for r by doing y/x in any given point.

\frac{8}{1.6} = \frac{15}{3}  = \frac{22}{4.4} = 5

One number is five less than a second number. Five times the first is 15 more than 6 times the second. Find the numbers
Shalnov [3]

Answer:

x = -45, y = -40

Step-by-step explanation:

Based on the first clue, we find out that

x + 5 = y

5x = 6y + 15

We can re-write the first equation to x = y - 5.

Therefore, the second equation can also be written as 5(y - 5) = 6y + 15

This can be simplified to 5y - 25 = 6y + 15

We can subtract 6y from each side, and add 25 to each side;

5y - 6y = 15 + 25

Therefore, -y = 40

Therefore y = -40.

Now let's plug this back into the original equation, to get : x  + 5 = -40

x=-45

Find the slope of the line. -7 , - 1/7, 7, 7/1
frutty [35]
Slope = (y₂-y₁)/(x₂-x₁)
by making (x₁,y₁) = (-2,2)   and    (x₂,y₂) = (5,3)
∴The slope = (3-2)/(5 - -2) = 1/7
