X Y
6 1
8 3
10 5
7 2
14 9
Step-by-step explanation:
X - 5 =Y
Answer:
Step-by-step explanation:
x/10 + 8 = x/2
10 could be a convenient common denominator
x/10 + 80/10 = 5x/10
x + 80 = 5x
80 = 4x
x = 20 gallons.
Y=ax+b, y=cx+d (a≠0, c≠0)
If the two line cross perpendicularly ⇔ ac= -1
So a tangent of the perpendicular line is "-(1/5)".
Then, the equation of the perpendicular line is y=-(1/5)x+a (a is <span> y-intercept</span>).
On the other hand, this equation pass r(1, 3), so
3 = -(1/5) times 1 + a
∴ a=16 / 5
Therefore, y=-(1/5)x+16 /5 is answer.
By the way, I'm Japanese so if you find some mistakes in my English, please let me know.
Answer:
Step-by-step explanation:
The slope-intercept of 4x-2y=3 is (-3/2) which is -1.5 in decimal form.
The slope-intercept of 3y+x=5 is (5/3) which is 1.666...
