Algebra 2 help? Please

There are two numbers with the following properties. 1) The second number is 3 more than the first number. 2) The product of the two numbers is 9 more than their sum.Which of the following repressents

How do you solve this algebra 2 question

y^2 - 3y + 3 = 0-... y^2 - 3y + 3 = 0 The Quadratic Formula: x = [ -b ± √ ( (b)² - 4(a)(c) ) ] / 2(a) x = [ -(-3) ± √ ( (-3)² - 4(1)(3) ) ] / 2(1) x = [ 3 ± √ ( 9 - 12 ) ] / 2 x = [ 3 ± √3 i ] / 2 x =

Is it improper to have a fraction with a decimal in it

Like -5.5/3? Should I change it to -11/6? (this is for slope)-Yes it is improper. Since a decimal is a fraction, -5.5/3 is really just a fraction over a fraction. So yes you should change it.-Negative

Differentiation: Product and Quotient Rule

if f (2.9) = 4 f(2.9)=12 g(2.9)=8 and g(2.9)= 4 then... find (f/g) (2.9) and (f/f+g) (2.9) please help its urgent thanks so much-(f/g)(2.9) = f(2.9) / g(2.9) (f/g)(2.9) = (g(2.9)*f (2.9) - f(2.9)*

Linear system: equation with variables

The sum of two integers is 38. Four times the smaller is 65 less than three times the larger. Find the numbers. (practice questions for exam =| )-let the two integers be X and Y given, X+Y=38.......

Please help with this Calculus range/domain question. What am I doing wrong

I know my Calculus is incredibly rusty, but I have been getting the rest of the question right. Am I missing something here. The answers I have are being repeatedly marked as wrong for domain/range.

How do you solve a derivative using its definition: (f(x+h)-f(x))/h

can you do this one for me as an example: f(x)= 2x^2 +3x-f(x) = 2x² + 3x lim h->0 (f(x + h) - f(x)) / h lim h->0 (2(x + h)² + 3(x + h) - (2x² + 3x)) / h lim h->0 ((2x² + 4xh + 2h²) + (3x + 3h) - 2x²

How much people help

How many people is there 4 out of 5 when you have 897,934 people?-897,934 * 4/5 = 718347.2 but you cant have .2 of a person so round to nearest integer. 718347 Hope this helps.-4/5= .8 = 80% 897,93

Pre-algebra or Algebra 1

So this is really bothering me, Im 7 grade, (going to 8 grade next year) My math teacher just told me that i will skip pre-alAlgebrao directly to algebra 1 (Im happy, but I dont like that idea becaus

(Easy 10 points) Did I do this right

The answer for the calculation (3.65 x 1023 ) x (4.78 x 10-45)/(8.55 x 10-9) , rounded off to three digits, is approximately 2.04 x 10-15. Is this true or false? I got 2.04 x 10^-13. So would that

Which one of the following quadratic equations will have one root

a) c^2 + 10c - 25 = 0 b) 5x^2+8x+16=0 c) y^2-9=0 d) 16y^2-8y+1=0 e) -9x^2 + 12x + 4=0 and why?-1. -(-c+5 sqrt(2)-5) (c+5 sqrt(2)+5)=0 2. (4+(1-2 i) x) (4+(1+2 i) x)=0 3. (y-3)(y-3)=0 4. (4y-1)^2 5.

The parabola y= -x^2 + 8x + 2 will have:

a) a maximum of 16 b) a minimum of 16 c) a minimum of -46 d) a maximum of -18 e) a maximum of 18 explain :)-Im assuming that you are not in Calculus, so I will do this algebraically. y - 2 = -x^2 +

Why is my answer wrong

find derivative of (3x^2 - 6x + 8)/(6x + 7) rule: (uv - uv)/(v^2) (3x^2 - 6x + 8)/(6x + 7) (6x - 6)(6x+7) - (3x^2 - 6x + 8)(6) / (6x+7)^2 (35x^2 + 6x - 42 - 18x^2 - 36x +48) / (6x+7)^2 (18x^2 - 30x

MATH PROBLEM PLEASE HELP

Im so lost how do i solve: f varies jointly as q2 and h, and f=64 when q=4 and h=2. Find q when f=90 and h=5-Q=3 here is how you do it f=(k)(q^2)(h) 64=(k)(4^2)(2) 64/32=2 k=2 so then once you got k,
