Answer:
undefined
Step-by-step explanation:
X-4y=-11<=> -5x + 20y = 55
<span> 5x - 7y = -10</span>
=>0*x + 13*y = 45 => y =45/13 => x = 4*(45/13) -11 = 180/13 -11 =>
x = 37/13;
Answer:
A.-12x^2-5x-102
Step-by-step explanation:
We are given a polynomial of degree 2 where terms are not grouped and simplified.
We have
-21x^2+22x^2-13x^2-10x+5x-102
To get this in proper form we have to group the like terms first
x^2 term = -21x^2+22x^2-13x^2 = x^2 (-21+22-13)
= x^2(-34+22) = -12x^2
x terms are -10x+5x = x(-10+5) = -5x
Constant term is only one = -102
Hence the polynomial in simplified form is
-12x^2-5x-102
Answer:
9x-y = 5
Step-by-step explanation:
Equation of line in slope intercept form:
y-y1 = m*(x-x1), m=9, (x1,y1)=(4,31)
y-31 = 9*(x-4)
y-31 = 9x-36
9x-y = 36-31
9x-y = 5
Hello from MrBillDoesMath!
Answer:
x = 0 or x = 3
Discussion:
Solve
x^2 -2x = x =>
x^2 - 2x - x = 0 => (subtract x from both sides)
x^2 - 3x = 0 =>
x(x-3) = 0 => (factor "x" from each term)
x = 0 or x = 3
