Calculus

x2 + 3y = 7

3x + y2 = 3

3y = x2 + 7

y2 = -3x + 3

y = x2/3 + 7/3

y = ± √(-3x + 3)

If you draw the graphs of y = x2/3 + 7/3 and y = ± √(-3x + 3) in a graphing calculator, you will see that they don't intersect, so that the system of the given equations has not a solution.

17.2*40 = 17.2*(10*4) since 40 = 10*4

=(17.2*10)*4 by the associative rule for multiplication

= 172 *4

=(100+70+2)*4

= 400+280+8

= 688

x equals half y

None. When these two equations are graphed, the two lines are parallel.

Since they never intersect, there is no point that satisfies both equations.

-(2)Squared = 4

X= Ten in roman numerals

this means that copper is 2.7g/cm3

The answer is 96. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.

There's not enough information to answer that.

You also have to know:

-- Did they both start out from the same place ?
-- Did they both start out at the same time ?
-- How long was each of the five stops mentioned ?
-- What's the distance from the starting point to the station ?
-- How long can the car keep going at 200 miles an hour ?

Use the quadratic formula, with a = 1, b = 7, c = 9.

If you mean by 'used' when were they first discussed then that was probably the Pythagoreans of Greece around the 5th century BC. They didn't use them so much as argue about them!

The first mathematician to use them systematically was Abu Kamil Shuja ibn Aslam of Egypt, around the 9th century. He used them as solutions and coefficients of equations.

For more information please see the wikipedia article about irrational numbers.

This just means to list values of x and then plug them into the equation to find the value of y for that x.

so in (x,y) form:(1,8) (2,16) (3,24) and so on.

Y=1.25 or 1¼

If you graph this it will be a parabola that has each end pointing down. It crosses the x-axis at:

y=-2x^2+3x+5

y=-1(2x^2-3x-5)

y=-1(2x-5)(x+1)

y=5/2

y=-1

if the bar between the x's means multiply...

x2 is a binomial because if you have an x squared this indicates that...

x2 + 0x + 0 which is a binomial expression

-67

No, he was at least 1800 years too late!

you can try doing -3+3, -2+3 or just substitue the "x" with numbers that go in order like 5,4,3,2,1
