Mathematics
1 answer:
Harlamova29_29 [7]3 years ago
7 0

Answer:

C & D

Step-by-step explanation:

x² + 3x - 3 = 0

a = co efficient of  x² = 1

b=  co efficient of x = 3

c = constant = -3

roots = (-b ± \sqrt{b-4ac})/2a

    = (-3±\sqrt{3^{2}-4*1*[-3]} )/2*1

    = (-3±\sqrt{9+12})/2

    = (-3±√21)/2

  x = \frac{-3+\sqrt{21}}{2}     ; x =\frac{-3-\sqrt{21}}{2}

What is the slope of the line on the graph?
Bogdan [553]
Answer: 1/2

When looking at a graph, you need to follow the formula rise/run. This means that between two points, you need to find the distance up and down/left and right.

Looking at points (0,2) and (2,3), I see that the second point is 1 point higher. Let’s add that in for rise.

Rise/run

1/run

Now for run. The second point is 2 points to the right of the first one. Let’s add that in.

1/2

This is your answer! Hope this helps comment below for more questions :)

at a golf course, a worker placed 216 golf balls equally into 9 buckets. what is the ratio of golf balls to buckets?
ankoles [38]
The ratio is 216:9, which can be simplified to 72:3, which can be simplified to 34:1. This can also be written as a fraction (34/1). It means there are 34 golf balls for every one bucket.
