Answer:

The initial value is 29.5

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept ( also called initial value)

we have the points

(3,42.25) and (5,50.75)

Find the slope m

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{50.75-42.25}{5-3}

m=\frac{8.5}{2}

m=4.25

substitute in the equation

y=4.25x+b

<em>Find the value of b</em>

with the point (3,42.25)  ( or the other given point)

substitute the value of x and the value of y in the equation and solve for b

42.25=4.25(3)+b

42.25=12.75+b

b=42.25-12.75

b=29.5

substitute

The linear equation is

y=4.25x+29.5

The initial value is the y-intercept (value of y when the value of x is equal to zero)

For x=0

y=4.25(0)+29.5

y=29.5

Therefore

The initial value is 29.5

Answer:

54°

Step-by-step explanation:

Since the radius is not given, i'm going to assume that you are being asked for the measure of Arc FE, which is the angle the arc makes on the circumference when measured from the center of the circle.

Please refer to attached.

We can observe that FG and GE are both radii of the circle, hence they will have the same length. This also means that triangle FGE is an isosceles triangle. Which in turn means that ∠GFE = ∠GEF = 63°.

With this we can find the measure of arc FE

= ∠FGE

= 180° - 63° - 63°

= 54°

Hope this helps!

Simplify. –24 – 8 ÷ (–4) <br> A. –22 <br> B. –8 <br> C. –26 <br> D. 8
pishuonlain [190]
Hi there! The answer is A. - 22 

We can use PEMDAS to find our answer, which says divide first (before adding).

- 24 - 8 : (-4) = 

Since we divide two negative numbers, we end up with a positive value.
- 24 + 2 = 

Now we can add 
-24 + 2 = -22

What is the value of M ?
Murrr4er [49]

Answer:

m = 124 degrees.

Step-by-step explanation:

The sum of the interior angles of a triangle is 180.

The angle opposite m + 56 + 68 = 180.

The angle opposite m = 56.

The angle opposite m + m = 180, so 56 + m = 180.

Angle m = 124.

PLEASE HELP!!!!!!!!!!!!!!
ohaa [14]
In a circle, the arc is two times the length of the angle.

EFG = 98°

98 x 2 = 196

Minor arc EG = 196°

Hopefully this helps :)
