put this equation into standard notation
y=26/5x+529
go

i could say anything for x and anything for y. cause its a slope
thats the linear equation right there so..

slope intercept form and standard form are different ok ok. if you can figure it out 300 robux!!!1111

-5x2-3x+26=0
Two solutions were found :
x = -13/5 = -2.600 x = 2 Step by step solution :
Step 1 :
Raise x to the 2nd power Exponentiation :
Equation at the end of step 1 :
((0 - (5 • x2)) - 3x) + 26 = 0 Step 2 :
Simplify -5x2-3x + 26 Step 3 :
Pulling out like terms :
2.1 Pull out like factors :
-5x2 - 3x + 26 = -1 • (5x2 + 3x - 26)
Trying to factor by splitting the middle term
2.2 Factoring 5x2 + 3x - 26
The first term is, 5x2 its coefficient is 5 . The middle term is, +3x its coefficient is 3 . The last term, "the constant", is -26
Step-1 : Multiply the coefficient of the first term by the constant 5 • -26 = -130
Step-2 : Find two factors of -130 whose sum equals the coefficient of the middle term, which is 3 .
-130 + 1 = -129 -65 + 2 = -63 -26 + 5 = -21 -13 + 10 = -3 -10 + 13 = 3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -10 and 13 5x2 - 10x + 13x - 26
Step-4 : Add up the first 2 terms, pulling out like factors : 5x • (x-2) Add up the last 2 terms, pulling out common factors : 13 • (x-2) Step-5 : Add up the four terms of step 4 : (5x+13) • (x-2) Which is the desired factorization
Equation at the end of step 3 :
-1 • (x - 2) • (5x + 13) = 0 Step 4 :
Solve -1•(x-2)•(5x+13) = 0 Theory - Roots of a product :
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Equations which are never true :
3.2 Solve : -1 = 0
This equation has no solution. A a non-zero constant never equals zero.
Solving a Single Variable Equation :
3.3 Solve : x-2 = 0
Add 2 to both sides of the equation : x = 2
Solving a Single Variable Equation :
3.4 Solve : 5x+13 = 0
Subtract 13 from both sides of the equation : 5x = -13 Divide both sides of the equation by 5: x = -13/5 = -2.600 Supplement : Solving Quadratic Equation Directly
Solving 5x2+3x-26 = 0 directly Earlier we factored this polynomial by splitting the middle term. let us now solve the equation by Completing The Square and by using the Quadratic Formula
Parabola, Finding the Vertex :
4.1 Find the Vertex of y = 5x2+3x-26

sky go away you got it wrong
the answer is 26x-5y=2645
you can't have a negative at the start, which you got right @Widths, but you don't get rid of the fraction by diving. you multiply the denominator by everything in the equation to get rid of the fraction at the start
so 26/5 times 5 -y times 5 and 529 times 5
