Answer:
A. y = 
x + 10
Step-by-step explanation:
Given;
- The equation y = -7x - 5
- and another equation have a solution of (-2, 9)
If we equate the value of y in the first equation and the value of y in the second equation, then the solution of x should be -2 . Let's test this with equation A:
-7x - 5 = x + 10
-7x - x = 10 + 5
-
x = 15
x = (15 × -2) ÷ 15 = -2
*<em>This proves that equation A has the same value of x as our first equation!</em>
<em />
Let's test if equation A has a solution; y = 9:
y = (-2) + 10 = 9
*<em>This proves that equation A has the same value of y as our first equation!</em>
<em />
So the second equation is,
A. y = x + 10
<em />
24/54 reduce by dividing by 2 to get 12/27 <span />
Answer:
We conclude that it would take 4.5 minutes to fill the full barrel.
Step-by-step explanation:
It is stated that it took 3/4 of a minute to fill a barrel 1/6 full of water.
- It means if it took 0.75 minutes to fill the 1 part out of 6 parts.
It is conditioned that the water continues at the same rate.
so
Total parts of a barrel = 6
It takes 0.75 minutes to fill the 1 part of a barrel
Thus, multiply 0.75 by 6 will determine the total time in minutes to fill all the 6 parts of a barrel (or a full barrel).
i.e.
0.75 × 6 = 4.5 minutes.
Therefore, we conclude that it would take 4.5 minutes to fill the full barrel.
X = 6 if you use the above equality
