Match the graph

Mathematics
1 answer:
Sonja [21]3 years ago

Answer:

I

Step-by-step explanation:

This is a dotted line so we can automatically eliminate, b, e, g, h,  and j. The shading in greater than, so we can eliminate a, and d.

Now all we have left are c, f and *i,

*(because if converted to y intercept the sign will flip because the y is negative in this equation.)

Now convert to y intercept form (y=mx+b).

Flip the sign because some are negative.

C. y>(-5/2)x+0

F. y>-2x+9

I. y>(4/3)x-(5/3)

Now use rise over run, or you could just look at the b. B is equal to the y-intercept. It can't be 0 or 9, and (-5/3) is equal to -1.67. So isn't that the closest to what the y intercept looks like in the graph?

Please please help please ASAP
Vedmedyk [2.9K]

Answer:

VT = 50√3 , PT = 50

Step-by-step explanation:

Given

PV = 100

With reference angle 60°

hypotenuse (h) = 100

perpendicular (p) = ?

Now

Sin 60° = p/h

√3 / 2 = p / 100

p = √3 * 100 / 2

p = 50√3

Also

With reference angle 30°

hypotenuse (h) = 100

perpendicular (p) = ?

sin 30° = p/h

1/2 = p / 100

p = 100 / 2

p = 50

Hope it will help :)

Enter an inequality that represents the graph in the box.
Yuliya22 [10]

Find 2 points on the line:

We will use (2,2) and (0,-6)

Find the slope of the line which is the change in Y over the change in X:

(-6-2) / (0-2) = -8/-2 = 4

The slope = 4

Find the Y intercept:

y = 4x+b

use y1 for y and x1 for x

2 = 4(2) +b

2 = 8 +b

Subtract 8 from both side:

b = -6

Now you have the slope (4) and Y intercept (-6)

The equation of the line becomes y = 4X-6

The line is solid and the shaded portion of the graph is to the left of the line and it is a positive slope so the inequality would become

y ≥ 4x -6
