Does y equals 2x - 4 and y equals 2x - 5 have a common solution?
y=2x-4 y=2x-5 y=1 1=2x-4 -2x = -5 x=2/5 the solution is (x,y) = (2/5,1)
Square root of x squared plus 4 equals 4x?
Keep in mind the square root of x squared equals the absolute value of x. So, solving this equation for x involves the following: sqrt(x2)+4=4x |x|+4=4x Solving for |x| yields: |x|=4x-4 Using x=4x-4: -3x=-4, x=4/3. Using x=-(4x-4): x+4x=4 x=4/5 Checking both with the original equation shows that |4/3|+4=16/3=4*4/3, so x=4/3. However, |4/5|+4=24/5, which does not equal 4*4/5, so x does not equal 4/5. This means there is only one solution, x=4/3.
What is the solution to y - x equals 4?
y=x+4

What is the solution to 4x squared minus x minus 5 equals 0?
4x2 - x - 5 = 0 4x2 + 4x - 5x - 5 = 0 4x(x + 1) - 5(x + 1) = 0 (4x - 5)(x + 1) = 0 4x - 5 = 0 or x + 1 = 0 4x = 5 or x = -1 x = 5/4 o x = -1
What is the solution to x-4?
x-4<5
How do you solve for x if the question is 5x cubed equals 320?
5x3 = 320 x3 = 320/5 = 64 So x = cuberoot(64) = 4
What is the solution of X 9-4?
Assuming you mean x=9-4, x=5
What is the solution for 4 equals x-5?

What value of x is the solution of 4 3x plus 5 17?
The value of x is the solution of 4 3x plus 5 17 is given as follows . 12 x + 5 =17. 12x =12. Hence , x=1. ThusThe value of x is the solution of 4 3x plus 5 17 is 1.
Does y equals 2x - 4 and y equals 2x - 5 have a common solution?
y=2x-4 y=2x-5 y=1 1=2x-4 -2x = -5 x=2/5 the solution is (x,y) = (2/5,1)
What are the dimensions of a cube box if the volume is 514.125 in cubed?
If the length of a side is x inches then the volume is s3 cubic inches. So s = cuberoot(vol) ie s = cuberoot(514.125) = 8.011 inches (to 4 sf).
How do you know if a value is a solution for an inequality?
A number is called a "solution" for an inequality if, when you plug that number into the variable, the inequality becomes true. For example, 4 is a solution to the inequality "x + 5 < 10", because when you plug in 4 for x, you get "4 + 5 < 10", which is true. (4 plus 5 is 9, which is less than 10.) On the other hand, 6 is not a solution to the inequality "x + 5 < 10", because when you plug in 6 for x, you get "6 + 5 < 10", which is false. (6 plus 5 is 11, which isn't less than 10.)
What is the solution to this system of linear equations x plus y 4 x and minus y 6 (4 6) (6 4) (5 and minus1) ( and minus1 5)?
It is (5 and minus1).
5-8 4 x 2-1?
The solution to 5-8 4 x 2-1 is -60. The number name is negative sixty.
What the solution to 6x-4 plus 7 equals 5?
If: 6x-4+7 = 5 Then: x = 1/3
What is the solution set of x2-x-20 equals 0?
Given the equation x2 - x - 20 = 0, we see that it can likely be factored easily. Through simple trial and error we find that: (x - 5)(x + 4) = 0. From here, we set both terms equal to zero to find all possible solutions. x - 5 = 0 x = 5 and x + 4 = 0 x = -4. Substituting 5 and -4 back into the original equation yield true results. Thus the solution set is x = -4, 5. More formal, the solution set is {-4, 5}. Note: There are other methods of solving this problem such as the quadratic formula or by graphing the function.
