Answer:
y= 2x
Step-by-step explanation:
Find the slope of the original line and use the point slope fromula y-y1=m(x-x1) to find the line parallel to 2x-y=-1
Original
y=mx+b
y=2x +1
Let x be the number of girls
let 2x be the number of boys
given that There are 48 children.
<span>x+2x=48</span>x=48/3<span>x=16</span>
therefore there are 16 girls in the group...
For one gallon the car will travel (63/3) miles
therefore for 7 gallons the car will travel
(63/3)*7 = m
The right triangle has legs of x and 2.5 where x is the height up the wall that the ladder will reach. The length of the ladder is the hypotenuse of the right triangle.
According to the Pythagorean Theorem, x^2 + 2.5^2 = 12^2
x = 11.736 approx To the nearest tenth that is 11.7.
