Is (5, 10), (-8, 3), (-1, 7), (-5, 10) A Function ?
Answer:
Step-by-step explanation:
Notice that the inputs {5, -8, -1, -5} are all different. So we can immediately conclude that this is a function.
If the inputs were {5, -8, -1, 5}, this would not be a function, as the same input value (5) would result in two different outputs.

Answer:
u = 11
Step-by-step explanation:
6(u+5)=96
Divide both sides by 6
u+5=16
Subtract 5 from both sides
u=11
The variable, u, is equivalent to 11
Answer:
u=11
Step-by-step explanation:
If you multiply the parentheses by the outside number (6) it will bring you
6u+30=96 then take away 30 from each side to get
6u=66 last step is to divide by six
u=11

you are packing clothes for vacation and don’t want to take any button down shirts. You randomly choose three shirts from a jar containing three T-shirts, three polo shirts, and four button downs.
a) what is the probability that the first three shirts are button downs when you replace each shirt before choosing the next one?
b) what is the probability that the first three shirts are button downs when you do not replace each shirt before choosing the next one?
a) Because each pick is independent (we pick and then replace), we just have to find the probability of picking it out once, then cube that. This probability is 4/(3+3+4)=2/5. So, it is 8/125.
b) If we replace it, then we can do it in a strategic way:
The probability of picking it out the first time is 2/5. Now, there are 3 button downs and 9 shirts total.
The second time: 3/9=1/3
Now there are 2 and 8
Third time: 2/8=1/4.
The final probability is 2/5*1/3*1/4=1/30
Find the surface area of the figure below
Answer:
696.8 mm^2
Step-by-step explanation:
Does this make sense?
The surface area of figure is 696.8[tex]mm^{2}[/tex].
To understand more, check below explanation.
Surface area of figure:The given figure is combination of a triangular shape and cuboid.
We have to find surface area of given figure.
The surface area of combined figure is summation of area of four triangle and area of cuboid excluding top of cuboid.
The base of triangle = 13mm
Height of triangle = 10.3 mm
Area of 4 triangle [tex]=4*\frac{1}{2}*13*10.3=267.8mm^{2}[/tex]
Surface area of cuboid excluding top is computed as,
Area = (2*13*5) + (2*13*5) + (13 * 13)
Area = 130 + 130 + 169 = 429 square millimeters.
Hence, surface area of figure = 267.8 + 429 = 696.8[tex]mm^{2}[/tex]

The two angles add to 180
x+35.7 = 180
Subtract 25.7 from each side
x+35.7 -35.7 = 180-35.7

Martin dennis brought a wide screen television for $1720. He made a down payment of 15% and paid the balance over 18 months. The fiance charge was 4% of the amount financed. Find the down payment and the installment price of the televison and the monthly payment
Answer:
Down payment is $258
Installment price is $1766.22
monthly payment is $83.79
Step-by-step explanation:
Down payment is 15% of $1,720 which is $258 (15%*$1720)
Monthly payment can be computed using pmt formula in excel
=pmt(rate,nper,-pv,fv)
rate is the interest rate per month which 4%/12=0.33%
nper is the number of months of payments that is 18
pv is the finance amount which is the price minus down payment i.e $1462 *($1720-$258)
fv is the total finance amount plus interest which is unknown i.e 0
=pmt(0.33%,18,-1462,0)=$ 83.79
installment price =down payment +total repayment
=$258+($83.79*18)=$1766.22
At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 total calories and twice as many chicken wings as there are sliders. Write a system of equations that could be used to determine the number of chicken wings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.
Know a are:
CW=75. SL= 250. Y= 2x
CW= X= number of wings
SL= Y= number of sliders
X+Y= Total number of items, which can be rewritten as X+2X= total
Plug in the calories for the total
2(75X) +250X= 800
150x+250X= 400X= 800
X= 800/400=2 pieces of Slider
Double the amount for Wings=2x2=4
4wings/2 Sliders
The equations that could be used to determine the number of chicken wings and sliders in the combination meal is:
75w + 250s = 800
w = 2s
Where:
w = chicken wings
s = sliders
The two equations derived from the question are known as simultaneous equations. Both equations have to be solved together in order to determine the number of wings and sliders.
The total calories of wings = number of wings x calories of each wing
75 x w = 75w
The total calories of sliders = number of sliders x calories of each sliders
250 x s = 250s

Find the mean median and mode 12,13,14,9,7,8,15,10
Answer:
See below.
Step-by-step explanation:
The first thing to do is to put all the numbers in order.
[tex]7, 8, 9,10,12,13,14,15[/tex]
First, let's find the mode.
The mode is where there is a repeating number in a set. If you look, there is no repeating number. Which means, there is no mode for this set.
Next, we find the median.
[tex](10 + 12) / 2 = 11[/tex]
The median would be [tex]11[/tex].
Then, we find the mean.
For the mean, you add up all the numbers and you will divide it by how many numbers there are.
[tex]7,8,9,10,12,13,14,15 = 88[/tex]
[tex]88 / 8 = 11.[/tex]
The mean is [tex]11[/tex].

D. Vertex: (3, -1); zeros: (2,0), (4,0), y-intercept: (0,8)
Step-by-step explanation:
I used the desmos graphing calculator. Just plug in your equation and it should be pretty easy to find these points
Answer:
Vertex is (3,-1) zeros ( 4,0) (2,0) and y intercept (0,8)
Step-by-step explanation:
y = x^2 - 6x+8
Factor
y = (x-4) (x-2)
Set = 0 to find the zeros
0 = (x-4) (x-2)
Using the zero product property
x-4 = 0 x-2 =0
x=4 x=2
The vertex is 1/2 way between the zeros
(4+2)/2 = 6/2 = 3
y = (3-4) (3-2)
-1 (1)
y = -1
Vertex is (3,-1)
The y intercept is at x=0
y = 0-0+8
y =8

Meagan knits 1/10 of q scarf in 3/4 of annhour.What fraction of a scaf can megan knit in 1 hour
Answer:
2/15
Step-by-step explanation:
To solve this problem we just need to use a rule of three, relating the fraction of the scarf knitted and the amount of time.
So we have that:
1/10 of the scarf -> 3/4 hour
x of the scarf -> 1 hour
x * (3/4) = 1/10
x = (1/10) / (3/4)
x = (1/10) * (4/3)
x = 4/30 = 2/15
In one hour, Meagan knit 2/15 of the scarf.
Adrian is a songwriter who collects royalties on his songs whenever they are played in a commercial or a movie. Adrian will earn $40 every time one of his songs is played in a commercial and he will earn $130 every time one of his songs is played in a movie. Adrian earned a total of $1010 in royalties on 14 commercials and movies. Write a system of equations that could be used to determine the number of commercials and the number of movies on which Adrian's songs were played.
Answer:
Step-by-step explanation:
Let number of songs are played in a commercial be a
number of songs are played in a movie be b
Adrian earned a total of $1010 -> a*40 + b*130 = 1010 (1)
14 commercials and movies -> a+b = 14 (2)
(1) - (2)*40 = a*40 + b*130 - a*40 -b*40 = 1010 -14*40
-> b*90 = 450
-> b = 5
-> a = 14-5 = 9
The system of equation should be used is 40a + 130b = 1010
And, a + b = 14
And, the number of commercials and the number of movies on which Adrian's songs were played is 9 and 5
The following information should be considered:
Let us assume the number of songs are played in a commercial be a and number of songs are played in a movie be bSo, the equations are
40a + 130b = 1010
a + b = 14
b = 14 - a
Now
40a + 130(14 - a) = 1010
40a + 1,820 - 130a = 1010
-90a = -810
a = 9
And, y = 14 -9
= 5

What is the equation of the line that passes through the points (1, –1) and (3, –7)
Answer:
y = -3x + 2
Step-by-step explanation:
To find the slope of an equation you can do (y2-y1)/(x2-x1). Plug the values in from the equation and you get (-1+7)/(1-3), or 6/-2. This means the slope is -3. Then you plug the values of y and x into an equation y = -3x + b, and you get -1 = (-3)1 + b. Solve for b. -1 = -3 + b, (add 3 to each side) 2 = b. Then plug b back into your equation and you get y = -3x + 2
Answer:
-3x+2=y
Step-by-step explanation:
u need to find the slope intercept formula which mx+b=y
m=slope
b=y-intercept
first u should find the slope which is y2-y1/x2-x1
point 1:(1,-1)
point 2:(3,-7)
-7+1/3-1=-6/2=-3
m=-3
now replace the variables
-3(1)+b=-1
-3 times 1=-3
-3+b=-1
add 3 to both sides
b=2
now the equation is -3x+2=y
