If the value of a lies in between - 1 and 1 in the absolute value function y = a|x|, then the graph is farther from the ______________.y = -xy = xy-axisx-axis
SOLUTION:
If the value of a lies in between - 1 and 1 in the absolute value function y = a|x|, then the graph is farther from the y- axis. This is because the bounding lines of the function are the lines y = x and y = -x. Thus, when a varies from -1 to 1, the graph gets farther from the y-axis.

The functions r and s are defined as follows.r(x)=– 2x-2s(x)=x²+2Find the value of s (r(4)).s(r(4)) = 006ХŚ
The given functions are
r(x) = - 2x - 2
s(x) = x^2 + 2
To find s(r(4)), the first step is to substitute x = - 2x - 2 into s(x) = x^2 + 2. Thus, we have
s(r(x)) = (- 2x - 2)^2 + 2
s(r(x) = (- 2x - 2)(- 2x - 2) + 2
s(r(x) = 4x^2 + 4x + 4x + 4 + 2
s(r(x)) = 4x^2 + 8x + 6
Finally, we would substitute x = 4 into s(r(x) = 4x^2 + 8x + 2. Thus, we have
s(r(4)) = 4(4)^2 + 8(4) + 6
s(r(4)) = 64 + 32 + 6
s(r(4)) = 102
GH has a midpoint at M(-4.5, 5.5). Point G is at
(-10, 14). Find the coordinates of point H.
Answer:
(-1, 3)
Step-by-step explanation:
We could imagine the point G and H are points on a straight line.
We know that:
Point G is at (-10, 14)
Midpoint at M (-4.5, 5.5)
To calculate the x coordinate of the mid-point, we suppose to subtract x coordinate of H from coordinate x of G, divide by 2 to get the x coordinate of the midpoint m, which is -4.5
To calculate the y coordinate of the mid-point, we suppose to subtract y coordinate of H from y coordinate of G, divide by 2 to get the x coordinate of the midpoint m, which is 5.5
Therefore, x coordinate of H:
(- 10 - x) / 2 = -4.5
-10 - x = -9
- x = 1
x = - 1
And y coordinate of H:
(14 - y) / 2 = 5.5
14 - y = 11
- y = -3
y = 3

What is a fraction?A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces. A fraction, such as the one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English. A common, vulgar, or simple fraction is one that has a non-zero denominator that is displayed below (or after) the line on which the numerator is shown. Compound fractions, complicated fractions, and the mixed numeral fractions are examples of uncommon fractions that use numerators and denominators.
The numerator and denominator of the positive common fractions are both natural integers. The denominator tells how many of those equal parts make up single unit or fraction, whereas the numerator represents the number of equal parts. Since a whole can never be made up of zero parts, denominator cannot be zero.

mark is trying to remeber is account number his account has 6 digits he knows that the 6 digit are 2,3,5,7,8 and 9 but he cant rember the sequen in the correct order how many possible ways are there for mark to find the correct order
Answer:
720
Step-by-step explanation:
Formula: P (n,r) = n! ÷ (n - r)!
n = Total number of objects in a set
r = The number of items you choose
Mark knows the account number includes the numbers 2,3,5,7,8, and 9. There are obviously 6 numbers in total in this set and 6 he must choose in order to have a 6 digit account number, which the problem also directly states he has.
That means P(n,r) = P(6,6)
!/Factorial = Product of all positive numbers less than or equal to the given positive number
Therefore, 6! = 1 x 2 x 3 x 4 x 5 x 6
P (n,r) = P(6,6) = 6! ÷ (6-6)! = 720

While at the game, the four of them together had two orders of nachos ($2.50 each), four large cokes ($1.50
each), four candy bars ($0.75 each), and two bags of popcorn ($1 each). At the end of the evening, they split
the $20 gasoline bill to help Danny.
Answer:
Danny spent 41 dollars, and his friends spent 5 dollars
If everyone split everything, each person would have paid $13
You didn't clarify which type of answer you wanted, but I gave the two most logical ones
Step-by-step explanation:
Tickets: 5 * 4 = 20.00
Nachos:2.5*2= 5.00
Cokes: 1.5*4 = 6.00
Candy: 75*4= 3.00
Popcorn: 1*2 = 2.00
Cost at the game: 36.00
Gas bill: 20/4 = 5 dollars per person
Food and gas: 36 + 5 = 41.00
Danny spent 41 dollars, and his friends spent 5 dollars
However, if everyone split everything, each person would have paid $13
Find the volume of a cone with a base diameter of 6 yd and a height of 8 yd.Use the value 3.14 for 1, and do not do any rounding.Be sure to include the correct unit in your answer.
ANSWER
[tex]\begin{equation*} 75.36\text{ }yd^3 \end{equation*}[/tex]EXPLANATION
The volume of a cone is given by:
[tex]V=\frac{1}{3}\pi r^2h[/tex]where r = radius of the base of the cone
h = height of the cone
The diameter of the base of the cone is twice the radius. This implies that the radius of the cone is:
[tex]\begin{gathered} D=2r \\ r=\frac{D}{2} \\ r=\frac{6}{2} \\ r=3\text{ }yd \end{gathered}[/tex]Hence, the volume of the cone is:
[tex]\begin{gathered} V=\frac{1}{3}*3.14*3^2*8 \\ V=75.36\text{ }yd^3 \end{gathered}[/tex]That is the answer.

Based on the calculations, the length (L) of this rectangle is equal to 5 feet.
What is a rectangle?A rectangle can be defined as a type of quadrilateral in which its opposite sides are equal and all the angles formed are right angle.
How to calculate the area of a rectangle?Mathematically, the area of a rectangle can be calculated by using this formula:
A = LW
Where:
A represents the area of a rectangle.L represents the length of a rectangle.W represents the width of a rectangle.Given the following data:
Area of rectangle, A = 35 square feet.
Width of rectangle, W = (L + 2) feet.
Substituting the given parameters into the formula, we have;
35 = L(L + 2)
35 = L² + 2L
L² + 2L - 35 = 0
Solving the quadratic equation by using the factorization method, we have:
L² + 7L - 5L - 35 = 0
L(L + 7) - 5(L + 7) = 0
(L + 7)(L - 5) = 0
Therefore, the length (L) of this rectangle is equal to 5 feet since the dimension can not be negative.

Answer: F. $1.25
Explanation:
First, we need to find the probability of the coin landing faceup and facedown. We know that landing faceup is 3 times the probability of landing facedown. Since the highest probability is 1 (100%):
[tex]\begin{gathered} 3x+x=1 \\ 4x=1 \\ x=\frac{1}{4}=0.25 \end{gathered}[/tex]With this, we know that:
probability of the coin landing faceup = 3×0.25 = 0.75
probability of the coin landing facedown = 0.25
To find the expected value of each toss, we need to solve for the total of each value multiplied by its probability:
[tex]\begin{gathered} EV=\$1(0.75)+\$2(0.25) \\ EV=\$1.25 \end{gathered}[/tex]Therefore, the expected value of each toss of Coin C is $1.25

this week Linda got a promotion at work that came with a 4% pay increase. If now her monthly salary is $2,496, how much was he making before the raise?
We will say that x is the salary before the raise, to calculate how much the salary grows, we just have to take the given percent from x, in this case, the payment increased by 4% (0.04 expressed in decimal form) then the increased amount would be x times 0.04.
Salary increase = x*0.04 = 0.04x
Adding 0.04 x to the original salary x (before applying the increase) we get the actual monthly salary, $2,496, then we can formulate the following expression:
Current salary = original salary + salary increase
2,496 = x + 0.04x
From this equation, we can solve for x like this:
1. Factoring x on the right side of the equation:
2,496 = x(1+0.04)
2. making the sum inside the parentheses:
2,496 = x*1.04
3. Dividing both sides by 1.04:
2,496 / 1.04 = x * 1.04 / 1.04
2400 = x
x = 2400
Then, Linda was making $2400 before the pay increase
How do I solve this problem? Write an equation in slope intercept form, if that is not possible write it in standard form. 30. Passes through the point (-3,11) and is parallel to the line y=8
NSWER
y = 11
EXPLANATION
wo lines are parallel if they have the same slope and diffenrent y-intercepts.
In this case, we have to write the equation of a line parallel to the line y = 8, which is a line with a slope of 0 - i.e. it is a horizontal line. Therefore, the equation of the line we have to find must have the same form - y equal to a constant. This constant is the y-coordinate of the point where the line must pass through, (-3, 11).
Hence, the equation of the described line is y = 11.
