One of two things:
-There is no solution because they are parallel lines
- OR There is infinite solutions because they are the same line.
Standard form is
ax+by=c
where a,b,c are integers
y+3=1/4x
timesboth sides by 4
4y+12=x
minus x both sides
-x+4y+12=0
minus 12 both sides
-x+4y=-12
(I like x to be positive so)
times both sides by -1
1x-4y=12
a=1
b=-4
c=12
Answer: -4
Step-by-step:
-x^2+5x-1 x _ = 4x^2-20x+4
4x^2-20x+4 / -x^2+5x-1
In the blank the answer would be -4 which is the monomial.
Answer:
-2497
Step-by-step explanation:
Sn=n/2[2a+(n-1)d]
=22/2[2*-40+(22-1)d]
=11(2*-40+(21*-7)
= -2497
Answer:
x=13
Step-by-step explanation:
First, you add the x's together: 2x+x=3x
Now you have:3x-1=38
Add 1 to both sides: 3x=39
1 cancel on the left side of the equation
Divide 3 on both sides: x=39/3
3 cancels on the left side and 39 divided by 3 is 13:
x=13
Hope this helps!
