Answer:

i picked d because

Step-by-step explanation:

The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.

Product is -8 and sum is 2.<br> What are the two numbers

anygoal [31]

Step-by-step explanation:

Let the two numbers be x and y.

$\therefore \: xy = - 8...(1) \\ and \\ x + y = 2 \\ \\ \therefore \:x = 2 - y...(2)$

From equations (1) & (2)

$(2-y)y=-8\\\therefore \: 2y - y^2 = - 8\\\\\therefore \:y^2 - 2y-8=0\\\\\therefore \:y^2 - 4y+2y-8=0\\\\\therefore \:y(y - 4)+2(y-4)=0\\\\\therefore \:(y+2)(y - 4)=0\\\\\therefore \:(y+2)=0\:\: or\:\:(y - 4)=0\\\\\therefore \:y=-2\:\: or\:\:y =4\\\\ When \:\: y = - 2\implies x = 4\\\\When \:\: y = 4\implies x = - 2\\$

Thus, the two numbers are (4, - 2) or (-2, 4).

It takes 3 tractors 2 hours to plow a square field whose side is 600 meters. find the number of hours it would take 5 tractors t

NeTakaya

Answer:

5 tractors can plow a square field of side length 1,000 meters in 3.33 hours (3 hours 20 minutes)

Step-by-step explanation:

Let's find out how much each tractor can plow each hour.

$\frac{600^{2} }{3*2}=60,000m^{2}$ per tractor per hour

$1,000^{2}=1,000,000m^{2}$ is the area of the field of side length 1,000 meters

5 tractors can plow $300,000m^{2}$ per hour.

$\frac{1,000,000}{300,000}=3.33$ hours

An angle bisector is a ray starting at the vertex of an angle and divides the angle into two obtuse angles

AVprozaik [17]

False. An angle bisector is a bisector starting at the vertex and cutting an angle in half. It could be obtuse angles, but not always. It is usually two smaller angles. It is a ray, though.

I hope this helps!
