Answer is y= - 3/4x - 3 1/2
Step by step
We are looking for y = mx + b equation

First we find the two points on the graph
(-6, 1) and (2, -5)
Now we will find slope by finding change in y over change in x
(Y2 - y1) over (x2 - x1)
( -5 -1) over ( 2 - (-6) )
-6 over 8
reduce to -3/4 is slope “m”

Now we can solve for “b”
Substitute one set of points and your slope you just found into the equation
Let’s use ( 2, -5)

y = mx + b
-5 = ( -3/4) (2) + b
-5 = -3/2 + b
Now add 3/2 (same as 1-1/2) to both sides to isolate “b”
-5 + 3/2 = -3/2 + 3/2 + b
-3 1/2 = b

Now we have y= -3/4 - 3 1/2 for your equation!

Problem solved.

The angle marked a = 146 Work out the angle marked x.

notka56 [123]

Answer:

<h2>34 degrees</h2>

Basic facts:

<em>Corresponding angles are sometimes known as 'F' angles.</em>

angles in a straight line add up to 180

Step-by-step explanation:

To find the other side of <em>a</em> we follow the Basic fact annd do

180-146

=34

following the rule, we know that this is a flipped F

An F is a corresponding angle

therefore f is 34

Which table represents a function?

Anastaziya [24]

Answer:

The first box

Step-by-step explanation:

In a linear function you cannot have 2 of the same X numbers. Ex) You cannot have 2 -4's in the X row. In the Y, you may. But never the X.

Helpppppp pleaseeeeeee

NeX [460]

Answer: b)

Step-by-step explanation:

You can rule out A) and C), because you have to find area (no adding.)

To do this problem, you can individually multiply the estimated hieght and

width by 3 and then multiply together.

This is because there are 3 walls that each are 9 3/4 tall and 14 1/4 wide. To find total height and width, multiply by 3. Then find total area (lxw)

9 3/4 rounds to 10

14 1/4 rounds to 14

= 3 (10) x 3 (14)

D) is incorrect because you have to multiply each number by 3. (Or you can multiply by 6)

It is B)

to avoid a large shallow reef a ship set a course from point a and traveled 24 miles east to point b . the ship them turn and tr

Sever21 [200]

First, we are going to find the distance traveled by the ship adding the tow distances:
Distance traveled= 24 mi +33 mi=57 mi

Next, we are going to use the Pythagorean theorem to find the distance from $a$ to $c$ :
$d^2=24^2+33^2$
$d^2=576+1089$
d^2=1665
$d= \sqrt{1665}$
$d=40.8$ mi

Finally, we are going to subtract the two distances:
57 mi -40.8 mi= 16.2 mi

We can conclude that <span>if the ship could have traveled in a straight lime from point a to point c, it could have saved 16.2 miles.</span>
