Answer:
answer is
{X^2 + 4, X<2
{X + 4, X>2
Step-by-step explanation:
Because both solution set graph is at the begining hole at the value of X = 2 this means both sets doesn't contain 2.
Answer: yea you are
Step-by-step explanation:
Answer:
no because if the climate were to stay the same things wouldnt happen. like if it stayed hot plants wouldnt grow because the sun would dry out the soil and shrink the plants and a whole bunch of other problems.
Step-by-step explanation:
Subtracting the second equation by 18 on both sides, we have xy=-18. Next, we divide both sides by x to get y=-18/x Plugging that into the first equation, we have x+2(-18/x)=9. Multiplying both sides by x, we get x^2-36=9x. After that, we subtract both sides by 9x to get x^2-9x-36=0. Finding 2 numbers that add up to -9 but multiply to -36, we do a bit of guess and check to find the answers to be -12 and 3. Factoring it, we get
x^2-12x+3x-36=x(x-12)+3(x-12)=(x+3)(x-12). To find the x values, we have to find out when 0=(x+3)(x-12). This is simple as when you multiply 0 with anything, it is 0. Therefore, x=-3 and 12. Plugging those into x=-18/y, we get x=-18/y and by multiplying y to both sides, we get xy=-18 and then we can divide both sides by x to get -18/x=y. Plugging -3 in, we get -18/-3=6 and by plugging 12 in we get -18/12=-1.5. Therefore, our points are (-3,6) and (12, -1.5)
Answer:
R300 is positive number but -R300 is negative so, on a bank statement R300is thousand times larger than -R300
