How do you get: Show that 0.00317 is a rational number by writing it as a quotient if integers. (the 317 has a line above it.) Please Help? Bob Pursley showed how to do that very question in an earlier post. Look back perhaps 2-3-4 days and you will find it. I did look earler...

How do you: Complete the square as an aid in graphing. [I put exponents in ().] y = x(2) + 4x - 2 Please Help? The complete square of the x^2 binomial is x^2 + 4x + 4 = (x+2)^2 Therefore, add 6 to each side of the equation and you will have this still-valid equation with a ...

You can add or subtract complex numbers by treating the i as a variable and combining like terms. I am having a lot of trouble figuring out these equations with imaginary numbers. 1. (3+2i)+(7-i)= 2.(1-6i)+(2-i)= 3. (2+i)-(3+i)= 4.(4+i)-(2-i)= Can someone please walk me ...

1/3 - 5/6 = 1/X SOLVE 1/3 - 5/6 = 1/X Let's remove the denominators by multiplying by 12X 12X*(1/3) - 12X*(5/6) = 12X*(1/X) Clear the fractions. 4X - 10X = 12 -6X=12 multipy by -1 6X=-12 Divide both sides by 6 6X/6 = -12/6 X = -2 Check my work.

Math: Algebra2 Logarithms
Can someone help me find the value of B in this expression???? log 64 = Blog 4 5 5 Grrr... sorry about that. Here's the expression again: log (base = 5) 64 =B log (base = 5) 4 log 64 (base5) = log 4^b (base5) so 64 = 4^b by recognition of 64 as a power of 4, b=3

The area of a square garden in square feet is 49x^2-14x+1. Find the dimensions of the garden in terms of x. x^2=49x^2-14x+1 Then solve for x. 48x^2-14x + 1=0 (8x-1)(6x-1)=0 and solve for two values of x that are possible.

Find the polynomials roots to each of the following problems: #1) x^2+3x+1 #2) x^2+4x+3=0 #3) -2x^2+4x-5 #3 is not an equation. Dod you omit "= 0" at the end? #2 can be factored into (x+1)(x+3) = 0, so the roots are x=-1 and -3. #1 Use the quadratic equation for the roots [-b...

i was wondering if someone could check the answer i got for this math problem 7+2(5-2*9) = 243 I got -19 I think you're supposed to do the parentheses first...but within that, you're supposed to do the multiplication and THEN the subtraction, and then mult it by 2....then add ...

can somenone please check my answer and if i'm doing it right.... The sum of a number and 17 more than twice the same number is 101. N+17(2)=101 N=67? N + (2N +17)= 101 3N = 84 Take it from there THANK YOU! =)

Write an equation for the line that passes through (0,7) and is perpendicular to the line whose equation is y = 1/2x-1. my answer is y = 2x-7 is this correct? That can't be right, because when x=0, y must be 7. Furthermore, the slope of the line you want must be -2, to be ...

solve the systems of equation: First : 4x-2y = 2 Second: y = -4x-7 Should i solve by using substitution, elimination or multiply then use elimination? Try adding them. Add up the left sides and the right sides (after rearranging the second equation) the x term will drop out, ...

solve the equation: First: x + 3y = 5 Second: 3x - y = 5 should i use substitution or add them? "First" + 3 times "Second" eliminates y: x + 3y + 3*(3x - y) = 5 + 3*5 ---> 10 x = 20 ----> x = 2 Inserting in "First" gives: 2 + 3 y = 5 ---> 3 y = 3 ----> y = 1 This ...
