Yes that is my problem
Find the equation of the line.......Is this the problem you are having?
The roots of x^2 +px + q = 0 are real, and the roots of (x + a)(2x + p) = 0 are real, so the roots of x^2 + px + q + (x + a)(2x + p) = 0 are real.
y=-3/5(x-0)^2+3 =
y = -3/5 x^2 + 3 Is this the standard form? ( I don't know)
y + 3/5 x^2 -3 = 0 Is the the Standard form you are looking for?
5y + 3x^2 - 15 = 0 Another form.......they are all equal .....
The vertex is (6,20).
This is not a right triangle ...and no angles are given . Only the side lengths are given. You COULD use cos law to calculate the angles and start from there but it would be easier to use Heron's Formula to calculate the area...are you familiar with it ?
D**m but little do you know I can't do that :/

This is a Math Forum....people go here to get help with math problems. It really isn't set up as a place for chatting back and forth, which clutters the site . You should go look for a different forum for chatting with people. G 'Luck !
Thank you. (look at last post we talked on)
How do I answer it? Like what are the steps to answer it?
2x = 56 o or E + 56 = 2x + E ( both sides equal a straight line )
What part do you not understand?
Lets see you do better
I dont really understand
Yes?
No?
Maybe so?
Shaded area is everything above the line but not including the line
line equation is y = 1/2x - 1/2
answer y > 1/2x - 1/2 <======== you have this listed as incorrect answer....but it IS correct ! You just need to complet the work to get it in the correct form....don't be a lazy person just looking for the answer !
y > 1/2x - 1/2
0 > 1/2x - 1/2 - y multiply by 2
0 > x - 1 - 2y
or x - 2y -1 < 0

Lol, yes I can but will you check?
5x^2 - 20x + 1357 - 80x + 415 = 0
5x2 -100x + 1772 = 0 Bowl shaped parabola ... minumum value of the function will occur at the x value = - b/2a = - -100/10 = 10
use this value of 'x' in the equation to compute the minimum value of the fxn.
By casework, the number of ways is C(12,4) + C(11,4) + c(19,4) = 4701.
The difference in the heights is 12 + 10*sqrt(3).
Let's say that the number of 20 cent coins is x and the number of dollar coins is y. Since Jacob has 1 more 20 cent coin: x=y+1 Then there's also the statement,"The total value of the one-dollar coins is $5.40 more than the total value of the twenty-cent coins." Since x and y are the number of coints, if we multiply them by the value of each coin we will get to total value of each group of coins. 0.2x + 5.40 = 1y Let's multiply both sides by ten just to get the decimals out 2x+54=10y Now we can do substitution. Since x=y+1, let's plug that in. Remember to plug in with parentheses. 2(y+1)+54=10y 2y+2+54=10y 56 = 8y 7 = y If there are 7 dollar coins, there are 8 20 cent coints so 7+8 = 15 giving us 15 total coins
a. a*b + b*c + c*a = (-20,20,2) + (-20,30,5) + (50,10,8) = (10,60,15)
b. The area of the triangle is 10.
c. a*b + b*c + c*a = (1,1,1).
