What are the solutions (coordinate points) to the system of equations?

Viefleur [7K]

Answer:

x=0,-2

Step-by-step explanation:

Solve the solution by equaling them to each other and solve for x.

x^2+5x+6=3x+6

x^2+5x-3x+6-6=0

x^2+2x=0 (factor out one x)

x(x+2)=0

x has two solutions since there are two options of solving.

1. x=0/(x+2)

x=0

2. x+2=0/x

x+2=0

x=-2

William is digging a hole to plant a tree.The hole has to be in 2 ft deep.He is able to dig at a rate of 1/2 ft. per minute.Writ

Mars2501 [29]

Answer:

$y=-\dfrac{1}{2}x+2$

Step-by-step explanation:

Let

x = the amount of time William has been digging

y = the amount he has left to dig

The hole has to be in 2 ft deep. This means when William starts, the hole was 0 feet deep and has left 2 ft to dig. Hence, y-intercept is $b=2$

He is able to dig at a rate of $\frac{1}{2}$ ft per minute. Thus, the slope is $m=-\frac{1}{2}$ (negative because the depth left to dig is decreasing).

The slope-intercept form of the equation is $y=mx+b,$ so in your case this equation is

$y=-\dfrac{1}{2}x+2$
