Can you help solve 3a + a = 16

3a + a = 16 4a = 16 | /4 a = 4-3a means a + a + a so 3a +a is (a + a + a) + a which is a+a+a+a which is 4a does that help? Think of it this way, if you have 3 bananas in your and and are given one mo

How would I write the expression as a single logarithm:1/2logbase3(x) +3logbase3(x - 1)

1/2*logbaase3(x) + 3*logbase3(x - 1) = logbase3(x^1/2) + logbase3(x- 1)^3 = logbase3(x^1/2*(x - 1)^3)-Do. Your. Own. Math. Work.

How much percent do i need to pass my math course

im in grade 10 and i am currently getting 65% how much do i need to get on the exam to pass? whats the minimal percentage? please help!! thank you :)-Well if you want to pass with a 50 percent you ne

How do I find the x-intercepts of y= 2sin3x + √3

How do I find the x-intercepts of y= 2sin3x + √3 for 0 ≤ x ≤ 2π? Thanks!-x intercepts so y =0 so 2sin3x+√3=0 2sin3x=-√3 sin3x=-√3/2 you do sine inverse to find the angle and you get -60 degrees 3x=

Grade 12 math help, ASAP please!

Simplify as much as possible: ((x^(-2))+(y^(-2)))^(-2) Please help :)-((x^(-2)) + (y^(-2)))^(-2) Note this: x^(-2) is the same thing as 1/x^(2) y^(-2) is the same thing as 1/y^(2) Because the same

I need some help w/ algebra

Multiply or divide. Stateany restrictions on the variables. 1. (4a^5)/(7b^4) * (2b^2)/(2a^4) a. (4a^9)/(7b^6), a = 0, b = 0 b. (4a)/(7b^2), a = 0, b = 0 c. (7b^2)/(4a), a = 0, b = 0 d. 4/7a^9b^6,

How would I write the expression as a single logarithm: logbase3(36) - logbase3(4)

Subtraction of logarithms corresponds to division of the numbers themselves. So log 36 - log 4 = log (36/4) (in any base) which = log 9-Log 3(36) - Log 3 (4) = Log 3 (36/4) ………law of logs = Log 3 (9

Algebra...Help With Simplifying

I worked out this problem on the wordpad: 24 ÷ 1/2 + 5/8 x 6/7 I wound up with the answer 351/28. I wanted to check my answer on a calculator to see if I was right, and 1359/28 came up. So, now, I h

Using the shell method to calculate the volume of a solid. Calculus help

I have the following cal problem. Should I solve for x first or it it ok to go ahead and set up the integral using y? How would I solve it? Use the shell method to find the volume of the solid bounde

When do you use y' vs. dy/dx

They both mean the derivative of the function y right? So do they mean the same thing and theyre just different notations, or do they actually mean different things?-Whenever you are only differentiat

Uncertainty of limit? (ex:infty/0 )

Could you determine whether the following limit type is indeterminate, always has a fixed finite value, or never has a fixed finite value ? In the first case answer IND, in the second case you can use

I need some help with algebra please

Im horrible with algebra..so please help me with these! Thanks 1. Write an equation for the translation of y = 4/x that has the asymptotes x = 7 and y = 6. a. y = 4/x-6 + 7 b. y = 4/x+7 + 6 c. y =

How many years are between 1450 BC and now

Add 1450 to 1450 BC to get 0 and then add the year we are in. So you get 3461 years.-3461
