Answer:
y-3=4(x-10)
Step-by-step explanation:
Point Slope Form: y-y1=m(x-x1)
Where m=slope and (x1, y1) is a point on the line.
m=(y2-y1)/(x2-x1)=(11-3)/(12-10)=8/2=4
So the slope is 4,
y-3=4(x-10)
There are 16 fluid ounces in a pint, so we have 192/16=12 pints.
1) So the ratio of Machine A to B is x + 16 : x (x being the paper printed in machine b).
2) This is in 4 minutes so every minute it will be 152.
2) So x + 16 + x = 152, or 2x + 16 = 152.
3) So to find x, we can subtract 16 from both sides. 2x = 136
4) Now we just divide both sides by 2 to get x = 68.
5) So machine A will be 68 + 16 = 84.
= 84

Answer:
16.
Step-by-step explanation:
n - 7 = 9
Add 7 to both sides
n = 9 + 7 = 16.
Answer:
(-2.3,0.5)
Step-by-step explanation:
Take the second equation we have y= (-16-9X)/10
Then, we will subtitute the value of y on the first equation
8X - 10(-16-9X/10)=-23
Because 10 is denominator, it will delate with the numeber 10 that is multipling the -16-9X. Then the equation is
8X-(-16-9X)=-23
then: 8x+16+9X=-23 So, 17x=-23-16 => X=-2.3
Then we put the value of X in the first equation so
9 (-2.3) -10y=-16 => 10y=-16+20.7
So, y=0.5
