what is 4.5x10^-6 in standard notation?
The number 4.5x10⁻⁶ can be expressed in standard notation as decimal 0.0000045.
In scientific notation, numbers are expressed as a decimal number between 1 and 10 multiplied by a power of 10. In this case, 4.5 is the decimal number and 10⁻⁶ represents the power of 10.
To convert this to standard notation, we move the decimal point six places to the left to match the negative exponent of 10⁻⁶. This gives us:
0.0000045
In standard notation, this number is written as 0.0000045, where the zeros after the decimal point indicate the value of the number in the place of each digit. The last non-zero digit in this case is 5, which is in the sixth decimal place.

If y = 3x and 2x + 4y = 12, then 2x + 4(3x) = 12
Answer: Substitution
Step-by-step explanation:
GIVEN:
y=3x
2x+4y=12
Then, 2x+4(3x)=12
-----------------------------------------
Substitution: replacing one variable in terms of another variable.
As we can see from the given aspects, y=3x, and the conclusion expression has no y instead of 3x. This means it represented y in terms of x, which fits the definition of substitution that replaces one variable.

find the midpoint of H(6,7) I(-7,-6)
Step-by-step explanation:
um that's hard djrjrjrjjre
Answer:
(- [tex]\frac{1}{2}[/tex], [tex]\frac{1}{2}[/tex] )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]
Here (x₁, y₁ ) = (6, 7) and (x₂, y₂ ) = (- 7, - 6) , thus
midpoint = ([tex]\frac{6-7}{2}[/tex] , [tex]\frac{7-6}{2}[/tex] ) = ( - [tex]\frac{1}{2}[/tex] , [tex]\frac{1}{2}[/tex] )

Help!! 2(3x+4y)=4x+12y
Answer: x = 2y
Step-by-step explanation:
Let's solve for x.
2(3x+4y)=4x+12y
Step 1: Add -4x to both sides.
6x+8y+−4x=4x+12y+−4x
2x+8y=12y
Step 2: Add -8y to both sides.
2x+8y+−8y=12y+−8y
2x=4y
Step 3: Divide both sides by 2.
2x
2
=
4y

x=2y
Answer:
x=2y
Solve for x
2 ( 3x + 4y ) = 4x + 12y
6x + 8y = 4x + 12y
6x + 8y - 4x = 12y
2x + 8y = 12y
2x = 12y - 8y
2x = 4y
2x / 2 = 4y / 2
x = 4y / 2
x = 2y

Write the equation g(x) of the transformation of the parent graph f(x) = |x| reflected over the x axis.
Answer:
g(x) = -|x|
Step-by-step explanation:
f(x) = |x|
y = −f(x) Reflects it about x-axis
g(x) = -|x|
We start off with: f(x) = |x|
Reflection across x-axis
y = -f(x)
After: g(x) = -|x|

Kylie is in the business of manufacturing phones. She must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. The daily fixed costs are $600 and and the total cost of producing 4 phones in a day would be $1600. Write an equation for C,C, in terms of p,p, representing total cost, in dollars, of producing pp phones in a given day.
Answer:
C= 400P+ 600Step-by-step explanation:
In this problem, we are to model the equation for the total cost of producing a phone
Given that the fixed cost is $600
Also, the total cost of producing 4 phones in a day is $1600
hence the cost of producing 1 phone would be 1600/4= $400
the equation for producing p phones would be
C= 400P+ 600
This equation is the same as the equation of a straight line Y=mx+c
with C=y
400= m= gradient
P=x, the dependent variable
600= c the constant term.
Answer:
c=250+600

JL = 114, and
KL = 9x + 9,
Find KL.
Answer:
KL= 63
Step-by-step explanation:
JK=7x+9 , JL=114 , KL=9x+9 ( if the points are on the same line and point J at the end point and K in the middle)
*J_______________________K___________________________L
JL=JK+KL
114=7x+9+9x+9
114-18=16 x
16x=98
x=98/16=6
KL= 9x+9
KL=9(6)+9
KL= 63

Find the perimeter of the polygon with the given vertices Round your answer to the nearest hundredth
Answer:
16.93 units
Step-by-step explanation:
Length of a segment having extreme ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
ML = [tex]\sqrt{(4-1)^2+(0-4)^2}[/tex]
= 5 units
LP = [tex]\sqrt{(1+1)^2+(4+2)^2}[/tex]
= [tex]\sqrt{40}[/tex] ≈ 6.32 units
PN = [tex]\sqrt{(-1-2)^2+(-2-0)^2}[/tex]
= [tex]\sqrt{13}[/tex]
≈ 3.61 units
NM = [tex]\sqrt{(4-2)^2+(0)^2}[/tex]
= 2 units
Perimeter of the polygon MLPN = ML + LP + PN + NM
= 5 + 6.32 + 3.61 + 2
= 16.93 units

Answer:
y =1
Step-by-step explanation:
6(2y−9)=-42
Divide each side by 6
6/6(2y−9)=-42/6
2y -9 = -7
Add 9 to each side
2y -9+9 = -7+9
2y =2
Divide by 2
2y/2 = 2/2
y =1
GUYS PLZ HELP ME!!!!!!
Answer:
B E F G
Step-by-step explanation:
Polygons are 2 dimensional shapes with straight edges (no curved edges). The shape needs to be closed up entirely to be a polygon. It cannot have any intersecting line segments
A can't be a polygon because the shape isn't closed up entirely
C can't be a polygon because it is a 3d shape
D can't be a polygon because it has curved edges.
H can't be a polygon because it isn't closed up (there are no line segments).
I can't be a polygon because polygons cannot have intersecting lines
J can't be a polygon because polygons cannot have intersecting lines
