Answer:
This would mean 3x=5
so to isolate the x, we divide 5 by 3
and get x=5/3
We have 60% and 85% antifreeze
We need 140 gallons of 70% antifreeze
x + y = 140
.60x + .85y = .70 * 140
X = 84 gallons 60%
Y = 56 gallons 85%
Answer:
Point slope form:
The equation of line is given by: .....[1]
where m is the slope and a line contains a point .
As per the given statement:
Slope(m) = 3
. = (2, 1)
Substitute these in [1] we have;
therefore, the point slope form of a line with slope 3 that contains the point (2, 1) is;
This can be easily figured out. Check to see what points are on the bottom and that is your answer.
B
You have to add all the numbers then leave one and subtract it
