Answer:
a. [tex]5 + (-3x) = -4[/tex]
b. [tex]5 + (-3x) = 4[/tex]
c. [tex]5 + (-3x) = 14[/tex]
Step-by-step explanation:
Given
[tex]5 + (-3x)[/tex]
Required
Evaluate
(a) x = 3
[tex]5 + (-3x) = 5 + (-3*3)[/tex]
[tex]5 + (-3x) = 5 + (-9)[/tex]
Remove bracket
[tex]5 + (-3x) = 5 -9[/tex]
[tex]5 + (-3x) = -4[/tex]
(b) x = 1/3
[tex]5 + (-3x) = 5 + (-3*1/3)[/tex]
[tex]5 + (-3x) = 5 + (-1)[/tex]
Remove bracket
[tex]5 + (-3x) = 5 -1[/tex]
[tex]5 + (-3x) = 4[/tex]
(c) x = -3
[tex]5 + (-3x) = 5 + (-3*-3)[/tex]
[tex]5 + (-3x) = 5 + (9)[/tex]
[tex]5 + (-3x) = 14[/tex]

What is the polar form of 7 StartRoot 3 EndRoot minus 7 i?
In polar form the expression is ( 14 , 30 )
How the rectangular form is converted to Polar form ?To convert the expression x +iy to polar form ( r , [tex]\rm \theta[/tex] ) , the standard equations used are
r = [tex]\rm \sqrt {x^2 + y^2}[/tex]
tan [tex]\rm \theta[/tex] = y/x
The given expression is
7 √3 - 7i
x = 7 √3
y = -7
r = [tex]\rm \sqrt {(7\sqrt{3})^2 +(-7)^2}[/tex]
r = √196
r = 14
tan [tex]\rm \theta[/tex] = (-7)/(7√3)
[tex]\rm \theta[/tex] = 30 degree
Therefore in polar form the expression is ( 14 , 30 ).

Andy is buying a car.
He negotiated a 7% decrease on a £6 500 car.
He will pay the full balance in 12 equal monthly payments.
Calculate the amount paid each month.
Answer:
£503.75
Step-by-step explanation:
Andy is buying a car.
Step 1
We calculate the decrease
He negotiated a 7% decrease on a £6 500 car.
Decrease = 7% × £6500
= $455
Step 2
We calculate the new price of the car.
= Old price - Decrease
= £6500 - £455
= £6045
Step 3
We calculate the amount he pays every month.
We are told that:
He will pay the full balance in 12 equal monthly payments.
Andy's monthly payments =
New price/12 months
= £6045/12
= £503.75
Therefore, the amount he would be paying each new month = £503.75

What is the image of (4,−8) after a dilation by a scale factor of 1/4 centered at the origin?
Answer:
(1,-2)
Step-by-step explanation:
you just have to multiply the coordinates by 1/4
4x1/4=1
-8x1/4=-2
so the new coordinates are (1,-2)
The image of the given point is (1,-2).
Important information:
The coordinates of the point are (4,-8).Point is dilated by a scale factor of [tex]\dfrac{1}{4}[/tex] centered at the origin.Dilation:If a point is dilated by a scale factor of [tex]k[/tex] centered at the origin, then the rule of dilation is defined as:
[tex](x,y)\to (kx,ky)[/tex]
Using the above rule, we get
[tex](4,-8)\to \left(\dfrac{1}{4}(4),\dfrac{1}{4}(-8)\right)[/tex]
[tex](4,-8)\to \left(1,-2\right)[/tex]
Therefore, the image of the given point is (1,-2).

Answer:
4,188.79 and when its rounded its 4,188.8
Step-by-step explanation:
Volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.
What is Three dimensional shape?Three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given,
sphere with a diameter of 20 feet
Diameter is two times of radius
Diameter=2Radius
Radius =Diameter/2
Radius = 20/2=10 feet.
Volume of sphere=4/3πr³
π=3.142
Volume of sphere=4/3(3.142)(10)³
=4/3×3.142×1000
=4189.33 cubic feet.
Hence, volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.
