Answer:
Step-by-step explanation:
1/7x+1/3x=1
3/21x+7/21x=1
10/21x=1
x=21/10 hour or 2 hours and 1 minute
From the coordinates given the area will be as follows:
Area=length*width
<span>(4, -1), (-1, 4), (11, 16), and (16, 11).
length of the triangle is given by:
length=</span>√[(16--1)²+(11-4)²]=18.4
width=√[(4--1)²+(-1-4)²]=√(25+25)=7.1
thus the area will be:
A=18.4×7.1
A=130.64 sq. units
If the inequality symbol is ≤ or ≥ , then the region includes the parabola, so it should be graphed with a solid line. Otherwise, if the inequality symbol is < or > , the parabola should be drawn with a dotted line to indicate that the region does not include its boundary. Example: Graph the quadratic inequality.
Answer:
Step-by-step explanation:
y +7=-2/3(x + 6) can be written as y=-2/3 x -4 -7= -2/3 x -11
From this equation you can have the points where the line crosses the 'x' axis and the 'y' axis
One of which is obtained by doing y=0 and solving for x, it gives the 'x' axis crossing point
The other is obtained by doing x=0 and solving for y, it gives the 'y' axis crossing point
