Answer:
y = - [tex]\frac{1}{4}[/tex] x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 24, y = - 6
- 6 = 24k ( divide both sides by 24 )
[tex]\frac{-6}{24}[/tex] = k , that is
k = - [tex]\frac{1}{4}[/tex]
y = - [tex]\frac{1}{4}[/tex] x ← equation of variation

A dollar bill is about 0.00011 meter thick. What is this thickness in scientific notation?
Answer:
1.1 * 10 ^ -3
Step-by-step explanation:
Given the value of the thivkness of a dollar bill to be 0.0011metre
The standard scientific notation is expressed as A * 10^n
A is any value between 1 and 10 where n is any integer
0.0011 = 11/10000
0.0011 = 11 *1/1000
0.0011 = 11 * 0.0001
0.0011 = 1.1 * 0.001
0.011 = 1.1 * 10 ^ -3 (Note that the decimal point is shifted forward three times and the power is negative because the value is less than 1)

The expression is
[tex]2\log c+3\log k[/tex]
To find:
The value after condense the logarithm.
Solution:
We have,
[tex]2\log c+3\log k[/tex]
Using properties of logarithm, we get
[tex]=\log c^2+\log k^3[/tex] [tex][\because \log x^n=n\log x][/tex]
[tex]=\log (c^2k^3)[/tex] [tex][\because \log (ab)=\log a+\log b][/tex]

Triangle 1 is transformed onto triangle 2 in the graph below.
On a coordinate plane, triangle 1 is rotated to form triangle 2.
Which statement about the transformation is true?
The transformation is a reflection because triangle 2 is a flip of triangle 1.
The transformation is a dilation because triangle 2 is a different size than triangle 1.
The transformation is a vertical translation because triangle 1 slid vertically.
The transformation is a rotation because triangle 2 is a quarter-turn of triangle 1.

When graphing and using the slope-intercept equation, the slope top number tells us to do what? and the bottom number tells us to do what?
Answer:
Rise over Run
Step-by-step explanation:
The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.

Someone please help me on this I'm unsure if my answer is correct
Answer:
A. length = 23 cm; width = 5 cm
Step-by-step explanation:
So if 4 times the width would be [tex]4w[/tex] and 3 more than would be [tex] + 3[/tex], the equation would be [tex]l = 4w + 3[/tex]. If the perimeter is 56, then the new equation, [tex]2(4w + 3) + 2(w) = 56[/tex] can be formed. This simplifies to [tex]8w + 6 + 2w = 56[/tex], then to [tex]10w + 6 = 56[/tex], then to [tex]10w = 50[/tex], and finally, [tex]w = 5[/tex]. So the width is 5, and now plug it into the first equation.
[tex]l = 4(5) + 3[/tex], becomes [tex]l = 20 + 3[/tex], becomes [tex]l = 23[/tex].
So the dimensions are: length = 23 cm, width = 5 cm.
*And just to be sure, [tex]2(23 + 5) = 2(28) = 56[/tex] which is correct.
What are the zeroes of f(x)=(2x+3)(x-5)?
Answer:
[tex]-\frac{3}{2} , 5[/tex]
Step-by-step explanation:
The zeroes of a function are the x values of the points at which the graph intersects the x-axis. All points on the x-axis have a y-value of 0, therefore, we need to find out which values of x can be plugged in to have the result be 0. This function is already factored out. So, for each expression, find which input of x makes the result equal 0.
1) So, start with 2x + 3. Set it equal to 0 and solve for x:
[tex]2x + 3 = 0\\2x = -3\\x = -\frac{3}{2} \\[/tex]
Therefore, [tex]-\frac{3}{2}[/tex] is one of the zeroes.
2) Next, set x-5 equal to 0 and solve, too:
[tex]x - 5 = 0 \\x = 5 \\[/tex]
Therefore, 5 is one of the zeroes.
3) Thus, the zeroes are [tex]-\frac{3}{2}[/tex] and 5.

Option D is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
From the figure,
3x + 46 + 14 = 90
Now,
Simplifying.
3x + 60 = 90
Subtracting 60 on both sides.
3x = 90 - 60
3x = 30
Dividing 3 into both sides.
x = 10
Thus,
The value of x on the given figure is 10.

Jared has 12 more comic books than Zoe. If they have 28 comic books
altogether, find the number of comic books Jared has.
Your answer
Answer:
20 comic books
Step-by-step explanation:
Let us first set up a variable, x, for the number of books that Zoe has. If Jared has 12 more comics than Zoe, he would have x+12 books.
Given that Zoe and Jared have a total of 28 comic books, let us write an equation and solve for x:
[tex]x+x+12=28\\2x+12=28[/tex]
Now that we have a simplified version of the equation, let us solve for x by isolating the variable on the left side:
[tex]2x=28-12\\2x=16\\x=8[/tex]
We now know that x=8, and also that Jared has x+12 books. To find the number of comic books Jared has, let us add 12 to x:
[tex]x+12=\\8+12=\\20\\[/tex]
Therefore, Jared has 20 comic books.
I hope this helps! Please let me know if you have any further questions :)

Mike made 5/6 of his free throw attempts and Lisa made 7/9 of her free throw attempts. Choose two fractions that show 5/6 and 7/9 written with a common denominator.

C. 15/18
D. 27/36
E. 30/36
(This is multiple choice)
Answer:
B and C
Step-by-step explanation:
First you have to find a common denominator which would be 18. Then you need to multiply the denominators to get to 18. 6x3 and 9x2. Now whatever you do to the bottom you have to do to the top. So you would mutiply 5x3 and 7x2. The fractions you are left with are, 14/18 and 15/18.
