3)
the line intercepts x=0 with y=-1
and passes through (3,-2)
so over 3 x-"steps" it decreased by 1, so it's slope is (-1/3)=-0.333

in standard form the equation of the line is: y=(-1/3)x-1

4)
from the entries (-3,16) and (-1, 12) we have an x difference of 2 and y was reduced by 4
so the slope is=-4/2=-2
add this slope to the x=-1 value to get the x=0 value:
12+(-2)=12-2=10 (=y at x=0)

again fill the values into the line standard form:
y=-2x+10

Which inequality is true when R = 4.6

Nookie1986 [14]

Answer:

A. 3R > 14

Step-by-step explanation:

Here R = 4.6

Now we have to check each options and find which is true.

3R > 14

Dividing both sides by 3, we get

R > 14/3

R > 4.67

Which is true.

All other options are not true.

R + 32 >

R > -32 is not true.

R - 12 < -8

R < +4 is not true.

R/3 < 1

R < 3 is not true.

Hope this will help you.

Answer:A rubric is a grading tool that describes the criteria, or "what counts," for the assignment. It also describes each of the criteria according to gradations of quality, with descriptions of strong, middling, and problematic student work. The criteria are listed in the column on the left. The numbers in the top row indicate quality, with 3 being the best. The number 0 is something everyone wants to avoid. Students may use the rubric as a check list to determine if the writing meets the criteria of the assignment.

The flight of a cannonball toward a hill is described by the parabola y=2+0.12x- 0.0004x^2

Stells [14]

The computation shows that the placw on the hill where the cannonball land is 3.75m.

<h3>How to illustrate the information?</h3>

To find where on the hill the cannonball lands

So 0.15x = 2 + 0.12x - 0.002x²

Taking the LHS expression to the right and rearranging we have:

-0.002x² + 0.12x -.0.15x + 2 = 0.

So we have -0.002x²- 0.03x + 2 = 0

I'll multiply through by -1 so we have

0.002x² + 0.03x -2 = 0.

This is a quadratic equation with two solutions x1 = 25 and x2 = -40 since x cannot be negative x = 25.

The second solution y = 0.15 * 25 = 3.75
