Answer:
0=0
infinitely many solutions
Step-by-step explanation:
plug x=2y+3 as x into 3x-6y=9...so
3(2y+3)-6y=9, which has our x=2y+3 plugged in because that is what x equals
if you solve its
6y+9-6y=9
0y=0
y=0
making it 0=0
you can't go further from this
Answer:

Step-by-step explanation:
To find the slope of the given line, slope is the rise divided by the run of a line.
Slope =
Picking points (4, 18) and (8, 12)
Now;
x₁ = 4
y₁ = 18
x₂ = 8
y₂ = 12
Slope =
=
= 
Qr=1/2 mn = ms
mn=2 ms=12
ln^2=lm^2+mn^2 using phythagoras rule
ln^2=400
ln=20
Answer:
-
or -
+8x-16
Step-by-step explanation:
Given a second degree polynomial has a root 4 with multiplicity 2
That means, 4 is a repeating root of the polynomial.
Any second degree polynomial has at most 2 real roots.
⇒Both roots of the polynomial are 4.
and its expression can be written as c·
where c is a real number
⇒c·(
-8x+16)
⇒c
-8cx+16c
Also, the leading coefficient is given as -1
So, c = -1
and the expression becomes (-1)
-8·(-1)·x+16·(-1)
⇒<u>-
+8x-16</u>
90 divided by 40 and the equals 2.25 so it would be 2.25%
