Given:

The inequality is:

y>5x+3

To find:

The y-intercept, slope and type of line (solid or dotted).

Solution:

The slope intercept form of a line is:

y=mx+b            ...(i)

Where, m is the slope and b is the y-intercept.

We have,

y>5x+3

The relation equation is:

y=5x+3             ...(ii)

On comparing (i) and (ii), we get

m=5

b=3

It means the slope is 5 and the y-intercept is 3.

The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.

Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.

A 50-foot ladder leans against a building. If the base of the ladder is 6 feet from the base of the building, what is the angle
adell [148]

Answer:

The angle between the building and the ladder \theta = 6.9°

Step-by-step explanation:

Given data

AB = 50 ft = length of the building

BC = 6 ft

\theta = Angle between the ladder & building

From Δ ABC

\sin \theta = \frac{BC}{AB}

\sin \theta= \frac{6}{50}

\theta = 6.9°

This is the angle between the building and the ladder.

What is ...<br><br> 4x + 10= 2x - 6
Nata [24]
4x + 10= 2x - 6
Subtract 2x on both sides

4x - 2x + 10 = 2x - 2x - 6

4x - 2x + 10 = -6

2x + 10 = -6

Subtract 10 on both sides

2x + 10 - 10 = -6 - 10

2x = -6 - 10

2x = -16

x = -8

Please help me with this geometry question. i attached an image.
storchak [24]
Okay so triangle DEA = 71 degrees
And angle DEB = 90 degrees (right angle)
90 - 71 = 19 degrees
Angle EBA = 90 degrees (right angle)
That leaves the 90 degrees + 19 degrees = 109 degrees
There’s 180 degrees in a triangle so
180 - 109 = 71 degrees
