You can draw a graph of that equation. When you do that, the graph is a
straight line, and EVERY POINT on the line is a solution of the equation.
There are an infinite number of them.
You can find as many of them as you want. Pick any number you like
out of the air, and call it 'x'. Now find the number that's 2.4 more than
negative 0.4 of 'x' and that's 'y'. Together they form one solution to
the equation.
Answer:
0.708
Step-by-step explanation:
A great way to solve for probability is to create a fraction.
In our case, we can see that 17 out of 24 times they made it.
17/24 is our fraction.
Since the viniculum in a fraction represents division, we really have 17 divided by 24.
That is 0.7083.....
Rounding gives 0.708 as our final answer.
I would say that the answer is probably a screw and a lever.
Answer:
x is equal to four, and y is equal to negative eight.
Step-by-step explanation:
Let's solve it rearranging the first equation to define y:
9x + y = 28
y = 28 - 9x
Now we plug it in to the second equation:
3x + 3y = -12
3x + 3(28 - 9x) = -12
And solve for x:
3x + 84 - 27x = -12
-24x = -96
x = 4
Now we can plug that x value into one of the original equations to find the value of y
9x + y = 28
36 + y = 28
y = 28 - 36
y = -8
Let's test our answer by plugging that y value into the other equation, and seeing if we get the same x value:
3x + 3y = -12
3x + 3(-8) = -12
3x - 24 = -12
x - 8 = -4
x = 4
So we know our answer is correct.
