x(x+1) is WRONG! It means a function x of x-1. x*(x-1) is right. Use the ^ (caret) for exponentiation. x^2 means x squared. x/2y means Resources: Simplifier Portal, help with entering simplifier formulas (a must read).

12-4*11/2+15 no parentheses or exponents, so do the multiplication and division 12-4*11/2+15 12-44/2+15

The LCD is 4. 3. Multiply both sides of the equation by the LCD: Using the Distributive Property to multiply we get: and our fractions are gone. Now we will solve the equation. Start by getting the variable on one side of the equation by subtracting x from both sides: Next get the variable term by itself by adding 4 to both sides:

One number is 4 less than 11 times another. The sum of the two numbers is 92. Find the two numbers.---Equatios: x = 11y-4 x + y = 92---Substitute for "x" and solve for "y": 11y-4 + y = 92 12y = 96 y = 8---Solve for "x": x = 11y-4 x = 11*8-4 = 84-----Cheers, Stan H.

how do i write an open sentence using absolute value when i have a number line that has these numbers plotted -11 and -7 Find the middle of the interval: It is -9 Write the open sentence describing the distance from -9 as 2: |x-(-9)| = 2 x+9 = 2 or x+9 = -2 x = -7 or x = -11----- And then for these two numbers 4 and 12. Middle of the interval is 8

g(f(x)) = (f(x))^2 + 2 = (2x-3)^2 + 2 = 4x^2 - 12x + 11. c) Solve fg(x) = gf(x). Hint: Calculate f(g(x)) first. Then think. -----Comment from student: Thanks i have solved the two questions! im still stuck on the last one though, i have found fg(x) and gf(x), what would i do next?----- My response: If you just have the expressions for fg(x) and ...

Question 945338: One side of triangle is one-fourth the longest side.The third side is 11 feet less than the longest side. The perimeter is 124. Find all three sides. Answer by amarjeeth123(566) (Show Source):

One number is 11 more than another. Find the two numbers if three times the larger number exceeds four times the smaller number by 4... let larger number be x the smaller number be y.. x-y = 11.....1 3x = 4y +4 3x-4y=4.....2.. multiply equation 1 by -3 and add it to equation 2-3x+3y=-33 3x-4y=4-y=-29 y= 29.. x-y = 11 x-29=11 x= 29+11 x= 40

P(x = 4) in part A? Please show how you would calculate mean and standard deviation in the formula for the normal approximation to the binomial, and show the final formula you would use without going through the calculations. mean = np = 12*0.6 std = sqrt(npq) = sqrt(12*0.6*0.4) Find the area under the normal curve between x = 3.5 and x = 4.5 ...

(1) vertical asymptotes: x = −3, x = 0 Vertical asymptotes (values of x where the function is undefined -- i.e., has no value) are caused by factors in the denominator that are equal to 0. If there are asymptotes at x=-3 and x=0, then there are factors of (x+3) and x in the denominator. (2) horizontal asymptote: y = 0
