What is the ordered pair for 2y equals 4x-16 and 5y equals 4x plus 8?
2y = 4x - 16 5y = 4x + 8 Subtract the first equation from the second: 3y = 24 so that y = 8 Substitute this into the first equation: 16 = 4x - 16 ie 32 = 4x so that x = 8 So the solution is (8, 8)
What is the value of x in the equation -4x plus 2 26?
If the equation is -4x + 2 = 26, then you can solve like so: -4x + 2 = 26 -4x = 26 - 2 = 24 4x = -24 x = -6 Check: -6 * -4 = 24, 24 + 2 = 26
What is 4x plus -12 equals 8?
If: 4x+(-12) = 8 then 4x = 20 and x = 5
What is the inverse of the function f(x) 4x 8?
The inverse for f(x) = 4x + 8 isg(x) = x/4 - 2
What does 4x equals 8 what does x equals?
x= 24x2 = 8
What is the solution to 4x-8 equals 16?
4x - 8 = 16 Add 8: 4x = 24 Divide by 4: x = 6
Eight less than four times a number is the same as eight times the sum of the number and two What is the number?
Let's represent the # with x 4x-8=8(x+2) 4x-8=8x+16 4x-8x=16+8 -4x=24 x=24/-4 x=-6 The number is -6
What is 4x to the 2nd power plus 29x minus 24?
4x2+29x-24 = (4x-3)(x+8) when factored
What is the solution in 8-2x plus 6x equals 24?
8 - 2x + 6x = 24 collect (add) terms of x 8 + 4x = 24 subtract 8 from both sides 4x = 16 divide both sides by 4 x = 4
With math 4x equals 24 solve for x?
4x = 24 x = 24 ÷ 4 x = 6
What is 3x equals 12?
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
What is 8(4x- 12) =?
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
What are the demensions of a rectangle if the perimeter is 24 inches and the length of the rectangle is 4 inches greater than the width?
Let the length be x+4 and the width be x: Perimeter = 2(x+4+x) = 24 inches 2x+8+2x = 24 4x = 24-8 4x = 16 x = 4 Therefore: length = 8 inches and width = 4 inches Check: 8+8+4+4 = 24 inches
How can you solve -2x equals -4x plus 24 step by step?
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
Four times the sum of a number and 2 is 24 less than the number times 8 Find the number?
Suppose the number is x. The sum of the number and two is x+2 Four times the sum is 4(x+2) The number times 8 is 8x 24 less than the number times 8 is 8x-24 4(x+2) = 8x-24 4x+8=8x-24 so 4x = 32 and x = 8
8 plus 4x-x equals 8?
8 + 4x - x = 8 3x = 8 - 8 x = 0
How do you factor x2 4x-32?
If that's +4x, the answer is (x - 4)(x + 8) If that's -4x, the answer is (x + 4)(x - 8)
