Answer:
8x+55y ≤ 184
Step-by-step explanation:
8x: The x in 8x signifies the amount of books you can buy. So let's say you want to buy 4 books then x would be 4 and 8x would be equivalent to 42.
55y: The y in 55y signifies the amount of video games you can buy. So let's say you want to buy 2 video games then y would be 2 and 55y would be equivalent to 110.
≤: We're using this sign because you can spend a maximum of 184 dollars. Meaning that the amount you spend (which is the 8x+55y) has to be less than or equal to 184 dollars.
184: The amount of money you are able to spend total.

I did 14a already. How do I do 14b?
y = 0.167x - 0.467
T probability of rolling doubles after 45 tosses is 0.156
How to determine the regression equation?To do this, we enter the data values in a graphing calculator.
From graphing calculator, we have the following summary:
Sum of X = 550Sum of Y = 87Mean X = 55Mean Y = 8.7Sum of squares (SSX) = 8250Sum of products (SP) = 1375The regression equation is
y = bx + a
Where
b = SP/SSX = 1375/8250 = 0.16667
a = MY - bMX = 8.7 - (0.17*55) = -0.46667
So, we have:
y = 0.16667x - 0.46667
Approximate
y = 0.167x - 0.467
When the number of tosses is 45, we have:
y = 0.167 * 45 - 0.467
Evaluate
y = 7.048
Approximate
y = 7
45 tosses gives 7 doubles.
So, the probability is:
P = 7/45
Evaluate
P = 0.156
Hence, the probability of rolling doubles after 45 tosses is 0.156

Solve the equqtion of a circle (-3,4) and radius 4 units
Step-by-step explanation:
The equation of a circle is usually in the form: [tex](x-h)^2+(y-k)^2=r^2[/tex] where (h, k) is the center and r is the radius. With the information you provided you would have the equation: [tex](x+3)^2+(y-4)^2=16[/tex]. I'm a bit confused by "solve the equation of a circle" do you mean solve for y? if so you would just do
Original Equation:
[tex](x+3)^2+(y-4)^2=16[/tex]
Subtract (x+3)^2 from both sides
[tex](y-4)^2=-(x+3)^2+16[/tex]
Take the square root of both sides
[tex]y-4 = \pm\sqrt{-(x+3)^2+16}[/tex]
add 4 to both sides
[tex]y=\pm(\sqrt{-(x+3)^2+16})+4[/tex]
and then just change the sign to negative or positive depending on what half of the circle you want
Let's take this problem step-by-step:
I will assume that you want the standard form of the equation of the circle:
⇒ standard form: [tex](x-h)^2 +(y-k)^2=r^2[/tex]
(h,k) --> coordinate of circle's center --> (-3,4)r --> length of radius --> 4LEt's plug in the known values
[tex](x-(-3))^2+(y-4)^2 = 4^2\\(x+3)^2+(y-4)^2=16[/tex]
Answer: (x+3)² + (y-4)² = 16

Think of 5 positive integers that have a mode of 2 and 5, a median of 5 and a mean of 5.
Answer:
S = {2, 2, 5, 5, 11}
Step-by-step explanation:
So you can partially build a data set given this information. There is going to be 5 positive numbers and the median is going to be 5 so the data set is going to have 5 in the middle which should look like this
S = {a, b, 5, c, d} where a, b, c, d are the other values. Since it has a mode of 2 and 5 that means that the occurrences of 2 and 5 will be equal, otherwise it would only have 1 mode. and they have to appear at least twice since if they only appeared once, there would either be another mode, or the data set would have 5 modes.
So the data set is going to look like this
S = {2, 2, 5, 5, d}
Now the only thing left to do is calculate d. This is where you use the mean to determine the last value. The mean can be calculated as
(the sum of the data set) / (the amount of values in the data set)
Since we know the mean you can set up an equation to find the value of d
[tex]5 = \frac{2+2+5+5+d}{5}\\5=\frac{14+d}{5}\\25=14+d\\11=d[/tex]
so the last value is 11. This gives you the complete data set of 5 positive integers
S = {2, 2, 5, 5, 11}

What is zero of a polynomial?The zero of a polynomial can be defined as the points where the polynomial becomes zero as a whole.
In other words, The zeros of a polynomial p(x) are the values of x which satisfy the equation p(x) = 0
For example, the zero of the polynomial f(x) = x³- 12x²+ 20x is x = 0 or x = 10 or x = 2.
This is because f(x) = o when we substitute those x values.

D. WY= 132, m4Z = 101°
Y
Find the length of Wy and the measure of ZZ.
Answer:
x = 32
Step-by-step explanation:
Angle <X and angle <Z is has same measure because they are congruent angles so we can write the following equation:
6x - 60 = 2x + 68 transfer like terms to the same side of the equation
6x - 2x = 68 + 60 subtract/add
4x = 128 divide both sides by 4
x = 32
To find the measure of angle <Z and length of WY replace x with the value we found
WY = 3*32 + 5
WY = 101
m<Z = 2*32 + 68
m<Z = 132

m and n are both prime numbers. Find the values of m and n so that 2704× m/n is a perfect cube.
Since 2704 = 2⁴ × 13², we need [tex]m = 13[/tex] and [tex]n=2[/tex], since this gives
[tex]\dfrac{2704m}n = \dfrac{2^4 \times 13^2 \times 13}2 = 2^3 \times 13^3 = 26^3[/tex]
The values of m and n that make 2704 × m/n a perfect cube are:
m = 13 and n = 2.
We have,
We can start by factoring 2704, which is 52².
So we have:
= 2704 × m/n
= 52² × m/n
= (2² × 13²) × m/n
For the expression to be a perfect cube, we need all the prime factors to appear in groups of three.
Since 2 and 13 appear only once each, we need to find another factor that appears twice.
Since m and n are both prime, and the fraction m/n is simplified, there are only two possible values for m and n:
m = 2 and n = 13, or
m = 13 and n = 2
Let's try the first case:
2704 × m/n = 2704 × 2/13 = 416
416 is not a perfect cube, so this case does not work.
Now let's try the second case:
2704 × m/n = 2704 × 13/2 = 17696
17696 is 28³, which is a perfect cube.
Therefore,
The values of m and n that make 2704 × m/n a perfect cube are:

What is the expression of g(x) when we perform the following sequence of transformations onto the parent function fx=|x|:
a) compress horizontally by a factor of 2
b) shift right 1 unit
c) shift up 3 units
The expression of function g(x) is [tex]|\frac {x - 1}2| + 3[/tex]
How to determine the expression?The function is given as:
[tex]f(x) = |x|[/tex]
When the function is compressed horizontally by a factor of 2, the rule is:
f'(x) = f(x/2)
So, we have:
[tex]f(x) = |\frac x2|[/tex]
When the function is shifted left by 1 unit, the rule is:
f"(x) = f(x + 1)
So, we have:
[tex]f'(x) = |\frac {x - 1}2|[/tex]
When the function is shifted up by 3 units, the rule is:
g(x) = f"(x) + 3
So, we have:
[tex]g(x) = |\frac {x - 1}2| + 3[/tex]
Hence, the expression of function g(x) is [tex]|\frac {x - 1}2| + 3[/tex]

Helen is incorrect, the pressure decreases by greater than 20% and percent decrease is 23.80%.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Pressure before the change:
Area = 20 square cm = 0.002 square meters
P = 70/0.002 = 35000 N/m²
The force is increased by 10 newtons. The area is increased by 10cm²
New pressure = (70+10)/(0.003) = 26,666.667 N/m²
Percent decrease = [(35000 - 26,666.667)/35000]×100
= 23.80% (pressure decrease by 23.80%)
