Yes.

x=0 and y=-1

x = 5, y = 1

well you divide by ten

that's it

the answer is 0.33333

You can't simplify this any further. y=-x is the equation of a line.

• If y=3x+1, then y increases by 3 every time x increases by 1
• x=1 --> y=3(1)+1, y=4
• x=2 --> y=3(2)+1, y=7
• x=3 --> y=3(3)+1, y=10
• etc. It cannot be solved completely, rather it is a line that can be graphed with slope=3

-8x + 5 ≥ 11

Subtract 5 from both sides: -8x ≥ 6

Divide both sides by -8 (remember that dividing by a negative number changes the direction of the inequality): x ≤ -6/8 = -0.75

7/100

11(eleven)

It doesn't look like you have anything that can be determined. The most confusing part of this is the -2x 2y = -4

If y represents the year then

prevalence(y, y+1) = 0.12*(y-1999) + 13.8

It is not possible to show an image here but you can see some examples at the attached link.

2 infinity and beond

Y=-6

It depends on which sides A and B represent: the two legs, or one leg and the hypotenuse.

One kilolitre is equal to 1000 x 1000 = 1000000 millilitres. Therefore, 0.9 kilolitres is equal to 0.9 x 1000000 = 900000 millilitres.

It is -14.

Is simply 2x + 5, nothing more, nothing less.

Without knowing the plus or minus values of many of the given terms it is difficult to formulate an answer and whether or not the question should include any equality signs.

F- x - - band - was created in 2009.

49/16 = (7^2)/(4^2) = (7/4)^2 = ((4/7)^-1)^2 = (4/7)^-2

Thus as (4/7)^2 = 49/16 and 49/16 = (4/7)^-2

(4/7)^x = (4/7)^-2

Therefore x = -2.

There appears to be no equation in the question: only some disjoint expressions. Expressions cannot be solved.
