x^2+4x+7

2x^2 + 8x + 3 = 0

You cannot because you do not have an equation but an expression. There is no equals sign in the expression that is given.

the value of

x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0

One add one is 2, or better put, one plus one equals two. This is what it looks like in equation form: 1+1=2.

-7/5 For equations in Standard Form (Ax + By = C), slope equals -A/B. Or you could put the equation in Slope-Intercept form (y = mx + b) by solving for y and then finding the slope (m).

If you are looking for the slop intercept form it is: y = -3/2x + 8.5 The x isn't in the denominator here but you can put it in the numerator.

There is no solution. There is no number that can be put in place of 'x' that can make that statement true.

You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.

(200-90)+20=10

If you put an 'equals' sign ( = ) between the 'By' and the 'Cz', you have the generic equation for any straight line in 3-dimensional Cartesian coordinates.

put it in slope intercept form... x-y+3=0 -x -x subtract x from both sides of the equation -------------- -y+3=-x -3 -3 subtract 3 from both sides of the equation -------------- -y=-x-3 --- ----- -1 -1 divide both sides of the equation by -1 -------------- y=x+3

3x = 2y + 7 The standard form is: 3x - 2y - 7 = 0

Put the equation in this form: y=mx+b. Then m will be the slope. 2x3y+6=0 2x3y=-6 3y=-6/2x y=-2/2x y=-1/x This equation does not describe a straight line, but rather, it describes a curve.

How do you work out 5a plus 7 equals 9? Put in equation form5a+7=9 subtract 7 from both sides gives you 5a=2divide 5 from both sides gives you a=2/5 or .4substitute in .4 for your a to check answer5(.4)+7=9

If you mean: (3+8)-(2*5) then it equals 1

I believe you put in the wrong equation. This equation cannot be solved.

The given equation is : x + 5 + y = 0 Write in standard form of equation of straight line : y = mx + c . Where m is slope and c is y-intercept. We get: y = -x - 5 Which gives slope = -1 y-intercept = -5 To get x-intercept put y = 0 in the equation. We get x-intercept = -5

For the x intercept, put y = 0 in the equation. So 5x = 15 ie x = 3 So the intercept is (3,0)

Technically, a-2b=2 is the actual answer. Since you wouldn't have to put it in y=mx+b form, the equation can no longer be simplified.

a+b=16 is a linear equation in two variables. The variables are a and b. To solve a linear equation in 2 variables we need more information. We need either another equation, or a value to put in for a or b.Since we have neither, there is no more we can do.

If you mean: y=6+x/ x=7 Then that is the equation for a line. Put in any number for "x" and "y" will always be 6 more than that. In this case, y=13

if you put in what the problem equals then it can be answered

since a=5 you can put that into your equation of a+7=12 a=5 a+7=12 5+7=12 12=12 Correct So yes the given number is a solution to the given equation
