Answer:
required answer:-We know that in a octagon
numbers of sides=5
Let
value of each exterior angles =x
The sum of exterior angles=360°
ATQ[tex]{:}\leadsto [/tex][tex]\sf 5x=360 [/tex]
[tex]{:}\leadsto [/tex][tex]\sf x={\dfrac {360}{5}}[/tex]
[tex]{:}\leadsto [/tex][tex]\sf x=72°[/tex]
[tex]\therefore[/tex]Measure of each exterior angle of a octagon is 72°.

Can anyone tell me what this graph is in slope intercept form?
Answer:
the standard form equation is 1/2x^2-x-3/2=0
the vertex form equation is 1/2(x-1)^2-2=0
Step-by-step explanation:
Unfortunately, this can't be written in slope intercept form but I can write it in standard form(ax^2+bx+c) or vertex form (a(x-h)+k)
The vertex is (1,-2)
I estimate a=1/2 because the graph was widened and that can only be done by a fraction.
So, 1/2(x-1)^2-2=0
To find it in standard form
foil (x-1)(x-1)= x^2-2x+1
Then multiply by 1/2(x^2-2x+1)= 1/2x^2-x+1/2-2
To add 1/2-2. You mulitply -2 by 2/2 which equals 1/2-4/2 which equals -3/2
So the standard form equation is 1/2x^2-x-3/2=0
Express 345200000 in standard form

Answer:
7xy + 2x^2t
Step by step explanation:
You just group the like terms and simplify (pay attention to the signs)
5xy + 2xy = 7xy
-1x^2t + 3x^2t = 2x^2t
So the answer is : 7xy + 2x^2t

Fran and Winston have a combined income
of $80 000. One quarter of Winston's income
is the same as one-sixth of Fran's income.
How much does each person earn?
Answer:
Winston:$32,000
Fran:$48,000
1 of 4 parts is equal to 1 of 6 parts so if you add 4 parts to 6 parts you get 10. Divide the total amount by 10 and you get 8000. multiply 8000 to the amount of parts each person gets and you get that.

Determine if the ordered pair (1,-3) is a solution to the system of equations below:
y = x - 4
y = 9x - 12
Answer:
Yes, it is a solution
Step-by-step explanation:
(x,y) (1,-3)
a. Plug in x:
y= 1-4
y = -3 yes this is correct as -3 is on y.
b. Plug in X.
y=9(1)-12
y=9-12
y=-3 yes this is also correct as this also is -3 for y.
Graph f(x)=3/2x+2. plz help
Answer:
draw a line trough (2,3) and (0, 2)
Step-by-step explanation:
f(x)=(3/2)x+2
so 3/2 is your slope and 2 is your y coordinate of y-intercept
pick any point to start for example (0, 0) and go slope=rise/run=3/2 and you will end-up at (2,3)
now you have a point (2,3) and a second the y-intercept (0,2)
draw a line trough those points
Identify the equation in point-slope form for the perpendicular bisector of the segment with endpoints J(−24,−4) and K(−4,6).
Option A:
y + 6 = 2(x − 4)
Option B:
y − 6 = 2(x + 4)
Option C:
y + 1 = −2(x − 14)
Option D:
y − 1 = −2(x + 14)
Given:
Endpoints of a segment are J(−24,−4) and K(−4,6).
To find:
The equation in point-slope form for the perpendicular bisector of JK.
Solution:
Slope of JK is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{6-(-4)}{-4-(-24)}[/tex]
[tex]m=\dfrac{6+4}{-4+24}[/tex]
[tex]m=\dfrac{10}{20}[/tex]
[tex]m=\dfrac{1}{2}[/tex]
Product of slopes of two perpendicular lines is -1. So, product of perpendicular line of JK is -2.
Perpendicular bisector of JK passes through the midpoint of JK.
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-24-4}{2},\dfrac{-4+6}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-28}{2},\dfrac{2}{2}\right)[/tex]
[tex]Midpoint=\left(-14,1\right)[/tex]
Point slope form:
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
Perpendicular bisector of JK passes through (-14,1) with slope -2. So, the point slope form of JK is
[tex]y-1=-2(x-(-14))[/tex]
[tex]y-1=-2(x+14)[/tex]
Therefore, the correct option is D.

if f(x) = 2(x – 3) + 4, findf (-8).
Answer:
f(-8) = -18
Step-by-step explanation:
given :
f(x) = 2(x – 3) + 4
to find f(-8), simply substitute x= -8 into the function:
f(x) = 2(x – 3) + 4
f(-8) = 2[(-8) – 3] + 4
= 2[-8 – 3] + 4
= 2[-11] + 4
= -22+4
= -18

2.31 ×10 ^− 2
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
