Answer:
x=-3y+8
Step-by-step explanation:
2x+6y=16
2x=16-6y
2x=-6y+16
x=-6/2y+16/2
x=-3y+8
Look at the first line: y = (3/5)x - 3. What happens if you multiply each term by 5, to eliminate the fraction?
5y = 3x - 3
Compare this to the second equation,
5y - 3x = -10, or 5y = 3x - 10.
The coefficients of x and y (as 3 and 5 here) determine the slope of a straight line. Since 5y = 3x is present in both equations, the two lines MUST be parallel.
y = 4
4y = 6 => y = 6/4
y+4 and y =3/2 are both horizontal lines. Since they are horiz., they are parallel.
Answer:
the statement that is not supported by the trend in this scatter plot is that each additional pound adds about 1 hour of cooking time. (last option)
Answer:
B
Step-by-step explanation:
x² - 4x - 7 = 0
(x - 2)² = 11
We have
So
The rational term vanishes as <em>x</em> gets arbitrarily large, so we can ignore that term, leaving us with
and this happens if <em>a</em> = 1 and <em>b</em> = -1.
To confirm, we have
as required.
