the 4th root of 80 equals 2.9907
What s the value of k when the equation x squared plus 2kx plus 10x plus k squared plus 5 equals 0 has equal roots?
Equation: x^2 +2kx +10x +k^2 +5 = 0 Using the discriminant: (2k +10)^2 -4*1*(k^2 +5) = 0 Multiplying out the brackets: 4k^2 +40K +100 -4k^2 -20 = 0 Collecting like terms: 40k +80 = 0 => 40k = -80 => k = -80/40 Therefore the value of k = -2
What does 6x14 equals?
84
Y varies directly as the square of r If y equals 80 when are equals 4 find y when are equals 6?
80=4x, z=6x. find Z. x=80/4, x=20. z=6x20 z=120 answer= 120
How do you solve 8 equals 10x divided by 10 plus x?
8 = 10x/(10 + x) Multiply both sides by (10 + x) to give: 8*(10+x) = 10x Simplify: 80 + 8x = 10x Subtract 8x from both sides: 80 = 2x Divide both sides by 2: 40 = x
4x plus 6y equals 62 -6x plus 6y equals -18?
Subtracting gives: 10x = 80 so x = 8 and y = 5
4x plus 13 equals 93-6x what does x equals?
4x +13 = 93-6x. Adding 6x to each side gives: 10x+13 = 93. Subtracting 13 from each side gives: 10x = 80. Dividing both sides by 10 gives: x = 8.
3 times what equals 80?
3 times 80/3 = 80
In the equation 1-10x equals 81 what does x equal?
Oh, what a happy little equation we have here! Let's bring some joy to this math problem. To find the value of x, we need to isolate it by moving the numbers around. Start by subtracting 1 from both sides, then divide by -10. And just like that, you've found the value of x - it's -8.
Ten x squared minus 17 x equals 63?
actually,10x squared minus 17 equals 63 would come out to x equals the square root of 8.to work this out, you would first at 17 to both sides to get 10x squared alone.63 plus 17 equals 80. you now have 10x squared equals 80. then divide each side by ten to get x squared alone. 80 divided by 10 equals 8. now you have x squared equals eight. finally, to find x, you find the square root of each side. x squared's square root is x, and 8's square root is 2.82842712 but I'm assuming you only have to write out x=√8.but the other answer was a good try:)Improved Answer:-10x2-17x = 6310x2-17x-63 = 0When factored: (5x+9)(2x-7) = 0Therefore the roots of the quadratic equation are: x = -9/5 and x = 7/2
What is the answer for this equation 9 plus 11x equals 89 plus x?
Isolate the variable. Get it by itself. 9+11x=89+x 9+11x-1x=89+x-1x Subtraction property of equality 9+10x=89 9+10x-9=89-9 subtraction property of equality 10x=80 x=8 division property of equality.
What percent of 80 equals equals 96?
120% of 80 equals 96. 96/80 = 1.2 = 120%
How do you solve the equation 2x plus 30 equals equals 12x-50?
Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x
What is 80 in 16j equals 80?
80 is the product
What is the power of 4 equals 80?
2.9906975624424411 to the power of 4 equals 80.
