Answer:
b=5
Step-by-step explanation:
-b - 19 = -3b – 9
Add 3b to each side
-b+3b - 19 = -3b+3b – 9
2b -19 = -9
Add 19 to each side
2b-19+19 = -9+19
2b = 10
Divide by 2
2b/2 =10/2
b=5
18 divide by 2/3 ??????????
Answer:
30
Step-by-step explanation:
2/3 = .6
18/.6 = 30
Answer:
27
Step-by-step explanation:
If you want to divide a fraction, you have to divide it from it's reciprocal.
The reciprocal of 2/3 is 3/2.
Now, you have to multiply 3 and 18
18 x 3/2 = 54/2
54 divided by 2 is 27.

|x| means the absolute value, which is 4 and -4
Answer:
A
Step-by-step explanation:
So we have the equation:
[tex]|x|=4[/tex]
Solve for x. Use the definition of absolute value:
[tex]|x|=4[/tex]
This means that:
[tex]x=4\text{ or } x=-4[/tex]
And... we're done :)
The answer is A.
Solve for x. Evaluate and round your answer to 1 decimal place (tenths place). 10x=3588

pineapples are on sale for $1.50 per pound. Let y be the total cost in dollars of x pounds of pineapple which equation represents the situation
Answer:
y=1.5x
Step-by-step explanation:
Step 1: State what you know
Pineapples are 1.50 per pound
X represents how many pounds of pineapples you want to buy
Y represents how much do 'x' amount of pineapples cost in dollars
Step 2: Write the equation
y (the price of 'x' pounds of pineapple)=1.5(the cost of a pineapple)x(how many pounds of pineapples you bought)
Therefore the equation that represents the problem is y=1.5x
Answer:
y=1.5x

If you transform a line segment with a sequence of reflections, rotations, or translations, is it still a line segment?
Answer:
Yes
Step-by-step explanation:
Transformation of a two-dimensional shape or pre-image or polygon in mathematics is the manipulation of the two-dimensional object or pre-image or polygon within a system of coordinates or plane.
Transformations are a guide to the nature of the pre-image and image of two dimensional shape as it is translated within a system of coordinates
Rigid transformations are those that does not involve a change in the size of the pre-image, and includes reflections, rotations, and translations
Therefore, the line undergoes rigid transformation and the dimensions of the line is preserved making it still a line segment.

*PLEASE HELP , I DONT GET IT* What would be the volume of Prism F after a scale factor of 2 is applied to the dimensions?
Answer:
Increases by a factor 8.
Volume = 685.12.
Step-by-step explanation:
The volume will increase by a factor of 2^3 , because the volume is 3 dimensional.
That is the new volume = 85.64 * 8
= 685.12.
Find the solution for the following equation: 3x = 45
Answer: x = 15
Step-by-step explanation: Since x is multiplied by 3, divide both sides
of the equation by 3 to get x by itself, and show all your work!
Put both sides of the equation over 3
and cancel out the 3's on the left side.
It's tempting to want to show off your
math skills by doing the work in your head.
Don't fall into this trap!

Consider the function below. g(x) = 4x − 1 Find the difference quotient below (where h ≠ 0) and simplify your answer. g(x + h) − g(x) -------------------- h
Answer:
The difference quotient is 4.
Step-by-step explanation:
Given that:
[tex]g(x) = 4x - 1[/tex]
To find:
Difference quotient = ?
where [tex]h \neq 0[/tex]
Solution:
Formula for Difference quotient is given as:
[tex]\dfrac{g(x+h)-g(x)}{h}[/tex]
First of all, let us find out [tex]g(x+h)[/tex]
Replacing [tex]x[/tex] with [tex]x+h[/tex]
[tex]g(x+h) = 4(x+h)-1 \\\Rightarrow g(x+h) = 4x+4h-1[/tex]
Now,
[tex]g(x+h)-g(x) = (4x+4h-1 )-(4x-1)\\\Rightarrow g(x+h)-g(x) = 4x+4h-1 -4x+1\\\Rightarrow g(x+h)-g(x) = 4h[/tex]
Putting the above value in:
[tex]\dfrac{g(x+h)-g(x)}{h} = \dfrac{4h}{h}[/tex]
We are given that, [tex]h \neq 0[/tex]
[tex]\therefore \dfrac{4h}{h} = 4[/tex]
So, the difference quotient is 4.
N=1500(2^018t), t≥0 Find the initial number of cells (N) in the culture, given the exponential function.
Answer:
1500
Step-by-step explanation:
Step 1: Understand what the question is asking you
It wants to know how much cells do you start off with or in other words how much cells are in the culture when time is 0
Step 2: Set t = 0
[tex]N = 1500(2^{0.18(0)} )[/tex]
Step 3: Solve for N
[tex]N = 1500(2^{0.18(0)} )[/tex]
[tex]N = 1500(2^{0} )[/tex]
[tex]N = 1500(1 )[/tex]
[tex]N = 1500[/tex]
Therefore when the initial amount of cells there in the culture is 1500
How much will it take to do a work of 190J with 15w power
Answer:
[tex]\Huge \boxed{\mathrm{12.67 \ s}}[/tex]
Step-by-step explanation:
[tex]\displaystyle power \ (W) = \frac{work \ done \ (J)}{time \ (s)}[/tex]
[tex]\displaystyle P= \frac{W}{t}[/tex]
[tex]\displaystyle 15= \frac{190}{t}[/tex]
Solve for t.
Multiply both sides by t.
[tex]15t =190[/tex]
Divide both sides by 15.
[tex]\displaystyle t= \frac{190}{15}[/tex]
[tex]t \approx 12.67[/tex]
[tex] \bf \underline{ \underline{given : }}[/tex]
Work = 190 JPower = 15 W[tex]\bf \underline{ \underline{To \: be \: calculated : }}[/tex]
Calculate the time ?
[tex]\bf \underline{ \underline{

[tex] \boxed{ \bf{Power = \frac{Work \: done}{Time} }}[/tex]
[tex]\bf \underline{ \underline{Solution : }}[/tex]
We know,
[tex]\sf {Power = \dfrac{Work \: done}{Time}}[/tex]
[tex] \sf{ Time = \dfrac{Work \: done}{Power } }[/tex]
Substituting the values of work and power, we get:
[tex] \sf \implies{Time = \dfrac{190}{15} }[/tex]
[tex] \sf\implies{Time = 12.66 \: s}[/tex]
Thus,the time taken by a body is 12.66 seconds.
The original price of a toy was $400. It was increased by 20%. after some time the sale of toys decreased. So, the shop owner decided to decrease the price by 20%
What is the final price of the toy.
Answer:
$384
Step-by-step explanation:
Original price = $ 400
Increased price = 20% of 400
= [tex]\frac{20}{100}[/tex] * 400
= $ 80
Price after increase = 400 + 80 = $ 480
Decreased price = 20% of 480
= [tex]\frac{20}{100}\\[/tex] * 480
= $ 96
Price after decreasing 20% = 480 - 96 = $ 384
Final price of the toy = $ 384

Enter the numerator and denominator of a fraction in simplest form that is equivalent to 0.941941 Repeating.
Answer:
[tex]\frac{941}{999}[/tex]
Step-by-step explanation:
Let x = 0.941941........
Three digits are repeating. So, multiply both side by 1000
1000x = 941.941941...... (I)
x = 0.941941....... (II) {subtract equation (II) from (I) }
999x = 941
x = 941/999

Identify the roots of the equation x^2 = 9x − 14 by factoring. x = 2 or x = 7 x = −2 or x = 7 x = 2 or x = −7 x = −2 or x = −7
Answer:
x = 7, x = 2
Step-by-step explanation:
Given
x² = 9x - 14 ( subtract 9x - 14 from both sides )
x² - 9x + 14 = 0 ← in standard form
(x - 7)(x - 2) = 0 ← in factored form
Equate each factor to zero and splve for x
x - 7 = 0 ⇒ x = 7
x - 2 = 0 ⇒ x = 2

3(x+14)=42 plz need help now
Answer:
0
Step-by-step explanation:
So we have the equation:
[tex]3(x+14)=42[/tex]
Divide both sides by 3:
[tex]x+14=14[/tex]
Subtract 14:
[tex]x=0[/tex]
The value of x is 0
Answer: x=0
Step-by-step explanation:
Given
3(x+14)=42
Distributive property
3x+42=42
Subtract 42 from both sides
3x=0
Divide 3 on both sides
x=0
----------------------------------------------------
Given
3(x+14)=42
Divide 3 on both sides
x+14=14
Subtract 14 on both sides
x=0
Both ways are fine

On a zip-line course, you are harnessed to a cable that travels through the treetops. You start at platform A and zip to each of the other platforms. How far do you travel from Platform B to Platform C? (Please add the EXPLANATION)
Answer:
We have to travel 26.93 units from platform B to C.
Step-by-step explanation:
Length of a segment having coordinates [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is determined by the formula,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
From the graph attached,
Coordinates of the points B and C are (-25, -20) and (-15, 5) respectively.
Distance between these points B and C Or length of BC will be,
BC = [tex]\sqrt{(-25+15)^2+(-20-5)^2}[/tex]
= [tex]\sqrt{100+625}[/tex]
= [tex]\sqrt{725}[/tex]
= [tex]5\sqrt{29}[/tex]
= 26.93 units
Therefore, we have to travel 26.93 units from platform B to C.
Answer:
22.4 meters
Step-by-step explanation:
Because the distance and stuff I don't really know sorry
This diagram is a straightedge and compass construction. A is the center of one circle, and B
is the center of the other. Select all the true statements.
a. AC = BC
b. AC = BD
C. CD = AB
d. ABCD is a square
e. ABD is an equilateral triangle
f. CD = AB + AB
Answer:
Correct choices are a, b, e
Step-by-step explanation:
As per diagram, the circles are equal.
Since the distance AB is the radius of both circles:
AB = AC = BC = BD = AD = rSo the answer choices:
a. AC = BC
Correct, both equal to rb. AC = BD
Correct, both equal to rC. CD = AB
Incorrect. Half of CD is the leg of 30-60-90 triangle and is equal to r√3/2, so CD = AB√3d. ABCD is a square
Incorrect. ACBD is rhombuse. ABD is an equilateral triangle
Correct, all three sides are equal to rf. CD = AB + AB
Incorrect as CD = AB√3what is the answer to
