Answer:
y=13
Step-by-step explanation:
if x=20 when y=8 (we can creat equation )
x=2y+4 (you can prove that the equation is correct by substitute )
so the question is if x=30 find the value of y
30=2y+4
30‒4=2y
26=2y
26/2=2y/2
13=y

(60)x = 1, what are the possible values of x? Explain your answer.
Answer:
[tex]\frac{1}{60}[/tex]
Step-by-step explanation:
Problem:
The possible values of x in the equation (60)x = 1;
Solution:
Such a problem like this in which the highest power of the unknown is 1 will have just one solution.
60x = 1
To solve this, we take the multiplicative inverse of 60;
the multiplicative inverse of 60 = [tex]\frac{1}{60}[/tex]
Use this inverse to multiply both sides of the expression;
[tex]\frac{1}{60}[/tex] [tex]x[/tex] 60x = 1 x [tex]\frac{1}{60}[/tex]
x = [tex]\frac{1}{60}[/tex]

How much greater is (2^3)^2 than 2^3 x 2^2
Answer:
(2^3)^2/2^3X2^2 = 6/4 = 3/2
Step-by-step explanation:
(2^3)^2 = 6^2 = 36
2^3 X 2^2 = 6 X 4 = 24
Answer:
(2^3)^2 is 32 greater than 2^3 * 2^2
Step-by-step explanation:
(2^3)^2 = 2^(3 * 2) = 2^6 = 64
2^3 * 2^2 = 8 * 4 = 32
Difference:
64 - 32 = 32

How do you write 2x^5-9x^4-2x^2+10 in standard form?
Answer:
[tex]2x^5-9x^4+0x^3-2x^2+0x+10[/tex]
Step-by-step explanation:
A polynomial is in standard form when its terms are ordered from highest to lowest degree.
If the polynomial is missing terms, it must be completed by setting their coefficients to 0.
The given polynomial is:
[tex]2x^5-9x^4-2x^2+10[/tex]
The terms are ordered, but it's incomplete. The terms with exponent 3 and 1 must be included with zero coefficient.
Thus the polynomial in standard form is:
[tex]\boxed{2x^5-9x^4+0x^3-2x^2+0x+10}[/tex]

Describe a sequence of transformations that take isosceles trapezoid T to its image T'
Answer:If you rotate trapezoid BEFG counter clockwise 90° then reflected across pointy you will have the image above
Step-by-step explanation:
Transformation involves changing the position of a shape
The transformation from T to T' is a 90 degree counterclockwise
From the figure, we can see that:
The angle between isosceles trapezoid T and its image T' is a right-angle (i.e. 90 degrees)Figure T' is at the right of TThis means that:
A 90 degree counterclockwise through point D will take trapezoid T to T'
Hence, the required transformation is a 90 degree counterclockwise through point D

Evaluate -8a - b if a = 10 and b = 6
-86 is the value of -8a-b when a = 10 and b = 6.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is -8a-b
a and b are the variables in the given expression.
Minus is the operator of subtraction in the expression.
The value of a is given as 10 and b is 6.
Now we have to substitute the values of a and b in expression.
-8(10)-6
Eight times of ten is eighty
-80-6
Minus eighty minus six is minus eighty six.
-86
Hence, -86 is the value of -8a-b when a = 10 and b = 6.

[tex]P=53\text{ft}[/tex]
[tex]P = a+b+c[/tex]
[tex]53=2x-15+x+1+3x-29[/tex]
[tex]53=6x-43[/tex]
[tex]96=6x[/tex]
[tex]x=16[/tex]
[tex]a=2x-15[/tex]
[tex]a=2(16)-15[/tex]
[tex]\boxed{a=17}[/tex]
[tex]b=x+1[/tex]
[tex]b=16+1[/tex]
[tex]\boxed{b=17}[/tex]
[tex]c=3x-29[/tex]
[tex]c=3(16)-29[/tex]
[tex]\boxed{c=19}[/tex]
Answer:
1. x=16, a=17, b=17, c=19
2. k=-2
Step-by-step explanation:
1.
We can set up an equation where all the labeled sides add up to 53, and then find x:
(2x-15)+(x+1)+(3x-29)=53
6x-43=53
6x=96
x=16
Now that we know x, we can plug it back in to the expressions of the triangles to find their side lengths:
a=2(16)-15=17
b=16+1=17
c=3(16)-29=19
2.
Reminder: the slope of a line is its change in y over its change in x. We can then set up an equation:
[tex]\frac{2-k}{k-(-3)}=4\\\frac{2-k}{k+3}=4\\2-k=4k+12\\5k=-10\\k=-2[/tex]
what is the difference between the mean and the median of the set ( 3 ,8 ,10 ,15)
Answer:
You can think of the mean being acually mean because you have to do more work. When solving for the mean you add all the answers together then divide by the amount of numbers you have. For example, you have the numers (1, 2, 3) add them together (1+2+3) to get 6 then divide by 3 (6/3) to get a mean of two. The median is also fairly easy to remember. You line your numbers up least to greatest, left to right. and mark one off of each side at a time. If you have a even amount of numbers and reach the center, you add the two centers together then divide by to to get the median. If you have an odd amount of numbers, there should be one in the exact center left over.
Step-by-step explanation:
Mean) 3+8+10+15=36, 36/4=9 ANSWER=9
Median) 8+10=18, 18/2=9 ANSWER=9
In the case, the mean and median are the same and depending on context you could choose either method. It also helps that there is no outlyer. If there were on I would recomend finding the median.
