Which equation represents y equals x2-10x plus 30 in vertex form?
y=x2-10x+30=(x-5)2-25+30=(x-5)2+5
How do you solve 25x plus 30 equals15x?
25X + 30 = 15X subtract 15X from each side 25X - 15X + 30 = 15X - 15X 10X + 30 = 0 subtract 30 from each side 10X + 30 - 30 = 0 - 30 10X = -30 divide both sides integers by 10 (10/10)X = - 30/10 X = - 3 ----------------check in original equation 25(- 3) + 30 = 15(- 3) - 75 + 30 = - 45 - 45 = - 45 ----------------checks
How do you solve the equation 30x2 plus 91x -30?
(10x - 3)(3x + 10) so x = 3/10 or -10/3
Solve The Equation for negative three over ten x equals negative nine?
-3/10x = -9Multiply each side by 10x:-3 = -90xDivide each side by -90:x = -3/-90 = 1/30
What is the answer to 16x - 10x plus 9 99 - 30?
16x - 10x + 9*99 - 30 = 6x + 861
Which equation represents y equals x2-10x plus 30 in vertex form?
y=x2-10x+30=(x-5)2-25+30=(x-5)2+5
The quotient of thirty and ten times a number?
-3. 30/10x=0 <-Set up equation like this, then subtract 30 from both sides (10x=-30). Then divide both sides by 10 (x=-3).
Which equation represents yx2-10x 30 in vertex form?
Assume the expression is: y = x² - 10x + 30 Complete the squares to get: y = x² - 10x + 25 + 30 - 25 = (x - 5)² + 5 So the expression is in vertex form y = (x - h)² + k
How do you solve slope intercept form?
To find Slope intercept form you must... 1. get y by itself (No numbers beside it) 2.Get y on the left side if the equation 3. get x and b on the right side of the equation. Here is an example to better clairify... ( The / sign is divide ) 5y-10x=30 +10x +10x 5y=10x+30 /5 /5 y=2x+6 there is your answer
Why does dividing both sides of the original equation result in an equivalent equation?
if you have an unknown, it will still give the same answer. It's a hard one to explain, just by showing an example. x+3 = 6, therefore x=6-3, therefore x=3 now say I multiply everything by 10. 10x+30=60, therefore 10x = 60-30, therefore 10x is 30. x = 30/10 which is 3.
How do you solve 25x plus 30 equals15x?
25X + 30 = 15X subtract 15X from each side 25X - 15X + 30 = 15X - 15X 10X + 30 = 0 subtract 30 from each side 10X + 30 - 30 = 0 - 30 10X = -30 divide both sides integers by 10 (10/10)X = - 30/10 X = - 3 ----------------check in original equation 25(- 3) + 30 = 15(- 3) - 75 + 30 = - 45 - 45 = - 45 ----------------checks
What the answer too 10x-2y30?
10x-2y=30
What are the solutions to the equation x-3x27equal 8x-3?
If you mean: x-3x+27 = 8x-3 then -10x = -30 and x =3
How do you solve the equation 30x2 plus 91x -30?
(10x - 3)(3x + 10) so x = 3/10 or -10/3
What is the slope -10x 6y-30?
An equals sign seems to be missing. If it is -10x=6y-30 then the slope is -5/3. If it is -10x+6y-30=0 then it is 5/3.
Solve The Equation for negative three over ten x equals negative nine?
-3/10x = -9Multiply each side by 10x:-3 = -90xDivide each side by -90:x = -3/-90 = 1/30
Find the common factor of all the terms of the polynomial 10x - 30?
10x - 30 10(x - 3) ------------
