Hey there! I'm happy to help!
We have two values for y in terms of x. We can now create an equation to solve for what x is.
-4x+2=-x-1
We add x to both sides
-3x+2=-1
We subtract 2 from both sides.
-3x=-3
We divide both sides by -3.
x=1
Now, we can plug our x into one of the original equations and then solve for y!
y= -4+2
y=-2
We can also test this with the other.
y= -1-1
y=-2
Therefore, our solution is (1, -2), or x=1 and y=-2.
I hope that this helps!
That 2 means we multiply 4 by itself 2 times, and -4 x -4 = positive 16.

Answer:
A = 83.5m^2
Step-by-step explanation:
9 * 19 = 171m for the complete rectangle
9 - 4 = 5
5 * 19 = 95
95 / 2 = <u>47.5m</u> for the triangles
9 * 4 = <u>36m</u>
36 + 47.5 = <u>83.5m</u>

Answer:
72.1 cm
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle and is in radians (not degrees).
Here we convert 140° to radians: 140°(π/180°) = 2.44 radians.
Then the desired arc length is s = rФ = (29.5 cm)(2.44 radians) = 72.1 cm
Answer:
343
Step-by-step explanation:
There are quarters(25¢), loonies ($1), and toonies ($2)
And total number of coins is 9
If loonies ($1), and toonies ($2) are one, then quarters(25¢) is 7
If quarters(25¢), and toonies ($2) are one, then loonies ($1)is 7
If loonies ($1), and quarters(25¢) are one, then toonies ($2) is 7
So possible number number of combination for an item that cost between $10 and $12 is
= 1^3 * 1^3 * 7^3
= 343
hope this helps, stay safe :)
