Answer:
-5x - 32
Step-by-step explanation:
Use distributive rule : a(b + c) = ab + ac
3x - 8(x + 4) =3x + x*(-8) + 4*(-8)
= 3x - 8x - 32 {combine like terms}
= -5x - 32
52 regular playing cards are randomly dealt to four players with each players receiving 13 cards. What is the probability that each player will have exactly one ace
Answer:
The probability is 1/28,561
Step-by-step explanation:
Here, we want to find the probability that each of the players will receive exactly one ace.
In a deck of cards, we have 4 suites of 13 cards each, with each of the suites consisting of 1 ace.
So, the probability of getting an ace for each of the four players will be 4/52 = 1/13
Now, the probability of each of the players getting exactly one ace will be; first got one ace , second got one , third got one and fourth got one.
mathematically, this probability will be 1/13 * 1/13 * 1/13 * 1/13 = (1/13)^4 = 1/28,561

Answer:
The second choice
Step-by-step explanation:
Perimeter is calculated by adding the length and width but multiplied by 2. You add 3.2 and 1.5 and get 4.7. Multiply 4.7 by 2 would give you 9.4.
Area is multiplying the length and width. 3.2 multiplied by 1.5 would be 4.8
The answer is B.P=9.4 m, A 48m^2
the midpoint of ab is m (3,-4). If the coordinates of A are (8,-5), what are the coordinates of B
Answer:
work is attached and shown
The coordinates of the midpoint will be (-2,-3).
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. Given that the midpoint of AB is M(3,-4) and the coordinates of A are (8, -5).
The midpoint will be calculated by using the formula below:-
( 8 + x ) / 2 = 3
( 8 + x ) = 6
x = -8 + 6 = -2
( -5 + y ) / 2 = -4
( -5 + y ) = -8
y = -8 + 5 = -3
Therefore, the coordinates of the midpoint will be (-2,-3).

HELP ASAP my answer is B im pretty sure im wrong..
what is the equation of the line parallel to the line y=1/4x+5 and passing through the point (2,-1)
Answer:
The answer is
[tex]y = \frac{1}{4} x + \frac{1}{2} [/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The equation of the line is
y = 1/4x + 5
Comparing with the general equation above
Slope / m = 1/4
Since the lines are parallel their slope are also the same
Slope of parallel line = 1/4
So the equation of the line using point (2,-1) and slope 1/4 is
[tex]y + 1 = \frac{1}{4} (x - 2) \\ y - 1 = \frac{1}{4} x - \frac{1}{2} \\ y = \frac{1}{4} x - \frac{1}{2} + 1[/tex]
We have the final answer as
[tex]y = \frac{1}{4} x + \frac{1}{2} [/tex]
Hope this helps you
What’s the answer too this problem?
Think about the rule when multiplying powers together.
When multiplying two powers that have the
same base, simply add their exponents.
In this problem, each power has a base
of a and our exponents are m and n.
So adding these exponents together, we have a^m + n.

Did I do this right?
Answer:
no i dont think so
Step-by-step explanation:
1) multiply both sides by p
5/9=-10p
2) divide by -10 to get p
5/9 divided by -10/1
(keep, change flip)
5/9* -1/10
-5/90
therefore p=-5/90
Answer:
No, the answer is -18
Step-by-step explanation:
[tex]\frac{5}{9}[/tex]p = -10
[tex]\frac{5p}{9}[/tex] = -10 CROSS MULTIPLY
-90=5p DIVIDE BOTH SIDES BY 5

Eliminate the y in the following system of equations. What is the result when you add the two equations?
x+y=2
3x-4y=27
A.7x=29
B.x=-23
C.7x=35
D.4x=29
Answer:
C
Step-by-step explanation:
x + y = 2
Subtract x from both sides;
y = -x + 2
3x - 4y = 27
Substitute y;
3x - 4(-x + 2) = 27
Distribute;
3x + 4x - 8 = 27
7x - 8 = 27
Add 8 to both sides;
7x = 35
Divide both sides by 7;
x = 5

Answer:
x = 11/4
Step-by-step explanation:
[tex]\frac{x+8}{4} = \frac{6x+5}{8}[/tex]
Step 1: Cross-multiply.
[tex](x+8)*(8)=(6x+5)*(4)[/tex]
[tex]8x+64=24x+20[/tex]
Step 2: Subtract 24x from both sides.
[tex]8x+64-24x=24x+20-4x[/tex]
[tex]-16x+64=20[/tex]
Step 3: Subtract 64 from both sides.
[tex]-16x+64-64=20-64[/tex]
[tex]-16x=-44[/tex]
Step 4: Divide both sides by -16.
[tex]\frac{-16x}{-16} = \frac{-44}{-16}[/tex]
[tex]x = \frac{11}{4}[/tex]
If the original rectangle has an area of 2 cm squared and the scaled copied has an area of 50 cm squared what is the scale factor used to draw the scaled copy
Answer:
The scale factor used to draw the scaled copy is a factor of 5
Step-by-step explanation:
Here, we are interested in calculating the scale factor which was used to transition the original rectangle to the new scaled copy.
Firstly, there is a way to relate how the scale factor of the sides relate to the scale factor of the area. What we are saying here is that the scale factor of the sides is never equal to that of the area;
For a 2 cm^2 area let’s say the sides are 1 by 2 ; this gives us an area as said
Now, to get 50cm^2, we can see that the scale factor of both areas is 25 (2 to 50)
So the area has been scaled 25 times the original area. So how has the sides been scaled?
Using a general principle, the scale used to scale the area is the square of the scale used to scale the sides. What are we saying here? if the area is scaled by 4, then the sides are scaled by 2
So in this particular case, the area is scaled by a factor of 25
Now, the scale factor of the sides will be the positive square root of this which is 5
Hence, we can conclude that the sides of the smaller triangles were each multiplied by 5 to arrive at the sides of the bigger one which makes it that the scale factor used to draw the scaled copy is 5
K ( -3, 7 ), and L ( 8, 7 what is the slope?
the product of -3 and the square of a number decreased by 8.
Answer:
[tex]n^{2}(-3) -8[/tex]
Step-by-step explanation:
So the "product of" means the answer to a multiplication problem. That means -3 is being multiplied by a number which is squared. I used the variable "n" for number but you could use any letter you want.
This is what we have so far,
[tex]n^{2} \\[/tex] x -3 or [tex]n^{2}[/tex](-3)
The term decreased means to reduce or subtract. Which means we are left with....
[tex]n^{2}(-3) -8[/tex]

Richard buys a new car for $28,000. The car depreciates in value by 9% each year. Write an expression model to represent this situation. Use the variable y to represent the value of the car after t years.
Given :
Worth of new car , C = $28000 .
Depreciates in value of car , D = 9 % .
To Find :
Use the variable y to represent the value of the car after t years.
Solution :
Depreciation formula is given by :
[tex]y=C(1-\dfrac{D}{100})^t[/tex]
Putting all given values , we get :
[tex]y=C(1-\dfrac{D}{100})^t\\\\y=28000\times (1-\dfrac{9}{100})^t\\\\y=28000( \dfrac{91}{100})^t[/tex]
Therefore , the required equation is [tex]y=28000( \dfrac{91}{100})^t[/tex] .
Hence , this is the required solution .

Use the figure and find PT.
PT = 7x - 24 and TQ = 6x-2
Answer:
PT= 130
Step-by-step explanation:
Since T is the midpoint of segment PQ,
PT = TQ
7x - 24 = 6x-2
Subtract 6x both sides and add 24 both sides
7x -6x - 24 = 6x -6x -2
x - 24 + 24 = -2 + 24
x= 22
Substitue x into PT
7(22) - 24
154 - 24
PT= 130
