To Solve
Multiply by 2.1
8.4≤x
Answer:
8. y = x + 3 y = 2x + 4. SOLUTION: The graphs intersect at one point, so there is ... 10. y = 6 y = 3x + 4. SOLUTION: The two equations intersect at exactly one ... 18. y = x − 6 solution. The lines intersect at . 18. y = x − 6 y = x + 2. SOLUTION: ... 2x + 2y = 6 ... 28. y = 6x + 6 ... of the following systems of equations doesn't belong.
Step-by-step explanation:
8ft by 12ft and 10ft by10ft
Short Answer:Choice C [Third one down]
RemarkStart with the number so I can talk about the basic principle at work. The way to work it is to factor 162 into prime factors and hope there are at least 3 that are the same.
162 = 2 * 81
162 = 2 * 3 * 3 * 3 * 3
Now When you take the cube root of that, you get
![\sqrt[3]{2*2*2*2*3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B2%2A2%2A2%2A2%2A3%7D%20)
Here's the rule for a cube root. For every 3 prime factors under the cuberoot sign, you take out one and throw the other two away. So for cube root of 81,
you would factor it as ∛(81) = ∛(3 * 3 * 3 * 3) = 3∛3.
So out of four 3s under the cube root sign, you have 1 outside the root sign and one inside the root sign. 2 of the four 3s have been thrown away.
Continuation.X firstYou want 2 xs outside the root sign
∛(x * x * x * x * x *x ) = (x * x) You have thrown away 2 xs for every x outside the cube root sign
C = 6 There are no left overs.
Y secondFor the ys, you need 1 outside and 2 inside the root sign. that's because you need 5 altogether.
∛(y * y * y * y * y) = y ∛y^2
Answer c = 6; d = 2
