NeX [460]3 years ago
3 0

Answer:

Options B and D

Step-by-step explanation:

we have

y=\frac{1}{x-3} -----> equation A

y=3-x^{3} -----> equation B

Solve the system of equations by graphing

The solution of the system of equations is the intersection point both graphs

The solutions are the points (1.545,-0.687) and (2.956,-22.835)

see the attached figure

The approximate solutions are

(1.5,-0.7) and (2.9,-22.8)

Answer:

The equation is y = -3x.

The function is linear.

The point (2, -6) is on the graph of the function.

Step-by-step explanation:

<u>The function is linear.</u>

direct variation function is always linear. and linear means a straight line which is true in this case

<u>The equation is y = -3x.</u>

equation of line is y=mx+c

where, m=slope= -3.

it is linear so we are assuming it passes origin, (0,0).

m=(y2-y1)/(x2-x1)

now substituting m=-3 and (0,0) in x1 and y1.

-3=(y2-0)/(x2-0)

-3=y2/x2

y2=-3*x2

where y2=y, x2=x,

therefore,

y=-3x.

<u>The point (2, -6) is on the graph of the function</u>.

now,

y=-3x

substituting x=2,

y=-3(2)

y=-6

therefore,

if x=2, y=-6, (2,-6)

a display at an aquarium has sea stars to wolf eels in a ratio 4 : 5. It also has 5/8 as many rockfish as sea stars. there are 4
r-ruslan [8.4K]

The number of sea stars is 64.

What is a ratio?

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other.

In general, a: b, which can be interpreted as "a is to b," is used to denote a ratio between two quantities, let's say "a" and "b."

This ratio is expressed in fraction form as a/b. We utilize the same method for further simplifying a ratio as we use for further simplifying a fraction.

According to the question,

Ratio of sea stars to wolf eels = 4:5

Number of rock fish= 5/8 (Number of sea stars)

Number of wolf eels - Number of rock fish = 40

Using the given information, we get,

Number of sea stars = 8/5 (Number of rock fish)

On simplification,

Number of wolf eels = 80

So, number of sea stars = (4/5)*80

                                          = 64
