1 answer:

7 0

The relationship between goby fish and striped shrimp are truly/A symbiotic, for neither/B can survive/C without/D the other. No error/E

The correct option is A.

Yes, it should be is.
The sentence is referring to the relationship between the fish, not the fish themselves.
Relationship is singular.

What is symbiotic explain?

Symbiosis, any of several living arrangements between members of two different species, including mutualism, commensalism, and parasitism.
Both positive (beneficial) and negative (unfavourable to harmful) associations are therefore included, and the members are called symbionts.

Please Help!!! Determine the intercepts of the line that corresponds to the following table of values.

Orlov [11]

Answer:

y-intercept is (0,30); x-intercept is (52.5,0).

Step-by-step explanation:

Note that as x increases by 7 from -35 to -28, y decreases by 4 from 18 to 14. Thus, the slope of this line is

m = rise / run = -4/7.

Let's find the equation of the line. Start with the slope-intercept form:

y = mx + b. Use the slope m = -4/7 and the point (-28, 14) to find b:

14 = -(4/7)(28) + b, or

14 = -16 + b. Then b = 30, and the equation of the line in slope-intercept form is y = (-4/7)x + 30. The y-intercept is (0, 30).

Find the x-intercept by setting y=0 and solving the resulting equation for x:

y = (-4/7)x + 30 becomes (4/7)x = 30, and x = (7/4)(30) = 214, or 52.5.

The x-intercept is thus (52.5, 0).

Question 1 of 10

kvasek [131]

Given:

A parabola opens up or down and its vertex is at the point (h, v).

To find:

The equation of the parabola.

Solution:

A parabola opens up or down. It means it is a vertical parabola.

The vertex form of a vertical parabola is

$y=a(x-h)^2+k$ ...(i)

Where, a is constant and (h,k) is vertex.

The vertex of given parabola is at point (h,v). Putting h=h and k=v in (i), we get

$y=a(x-h)^2+v$

The required equation of the parabola is $y=a(x-h)^2+v$ .

Therefore, the correct option is A.

A line intersects the points(-22,-14) and (-18,-12). What is the slope-intercept equation for this line?

zaharov [31]

Hello there,

Well we are going to start off with the equation to find the slope based on the given points:

$\frac{y_{2} - y_{1} }{x_{2} -x_{1} }$

Now using the two given points we are going to plug in and solve:

$\frac{(-12)-(-14)}{(-18)-(-22)}$ = $\frac{2}{4}$ = $\frac{1}{2}$

From this you know that $\frac{1}{2}$ is the slope of the equation. However, to find the y-intercept we are going to use y = mx+ b and plug in one of the points to solve:

(-14) = $\frac{1}{2}$ (-22) + b

(-14) = (-11) + b

-3 = b

That means that the y-intercept is at (0, -3). Lastly, we are just going to plug all this into the slope-intercept form:

y = $\frac{1}{2}$ - 3

Hope I helped,
