Answer:
42 and 43.
Step-by-step explanation:
This problem can be solved just by knowing the sum of the page numbers, as page numbers on the same face are always one digit apart. Thus we can take 85, subtract 1, divide by 2, and then get 42,42, and add 1 back to the second-page number.
To check our work we can multiply 42*43 to get 1806.

what line y= 2/3 x - 2 is graphed below. if the system comprised of this line and the line y= -2x + 6 were solved, which of the following would be the y-coordinate of the solution?
1) y=0
2) y=7
3) y=3
4) y=-4
plz help asap thank you in advance!! :)
Answer:
(1) y = 0
Step-by-step explanation:
This question uses System of Equations to solve it.
Because both equations are equal to y, we can set both of the equations to equal each other and use basic algebra to solve for x:
2/3x -2 = -2x + 6
8/3x -2 = 6
8/3x = 8
x = 3
Because we are looking for the y-coordinate, plug 3 into one of the equations and solve for y (I'm going to use y = -2x + 6):
y = -2(3) + 6
y = -6 + 6
y = 0
That's your answer!
You can even prove it by using Desmos (this is a free graphing website), write the two equations, and then you can see the point where they intersect (I attached an image below).

Your friend's answer: (2x(x-1)(x+2)) / (6x(x-5)(x-5))
Answer:
The friend's answer is incorrect.
The correct answer is:
[tex] \dfrac{3(x - 1)}{x + 2} [/tex]
Step-by-step explanation:
[tex] \dfrac{x^2 - 1}{x^2 - 4x - 5} \div \dfrac{2x^2 + 4x}{6x^2 - 30x} = [/tex]
To divide by a fraction, multiply by its reciprocal.

the radius of a semicircle is 1 kilometer. what is the semicircle's perimeter? use 3.14 for pie.
Answer:
5.14 km
Step-by-step explanation:
A semicircle is 1/2 of a circle so the perimeter is just 1/2 of the circumference
C = 2 * pi r for a circle so for a semicircle
1/2* 2* pi *r
pi*r
3.14 * 1
3.14
If we want to include the piece that closes the semicircle, we need to add the diameter
d = 2r = 2(1) = 2
2+3.14 = 5.14
simplify.

The average movie ticket price in dollars since 1980 can be modeled by 0.142x + 1.93 where x is the number of years since 1980. What values of x would you use to find the average movie ticket price in 1985, 1999, and 2010? Find the ticket prices for each of those years rounded to the nearest cent. Submit your x-values, ticket prices, and all solution steps to earn full credit.
Answer:
Step-by-step explanation:
1985:
x = 5 years ( 1980 to 1985- 5 years)
0.142x + 1.93 = 0.142*5 + 1.93
= 0.71 + 1.93
= $ 2.64
1999:
x = 19 years
0.142x + 1.93 = 0.142*19+ 1.93
= 2.698 + 1.93
=4.628 = $ 4.63
2010:
x = 30 years
0.142x + 1.93 = 0.142*30 + 1.93
= 4.26 + 1.93
= $ 6.19
In this unit, you explored different reasons and incentives to save, such as saving for a down payment on a large purchase, financial security for emergencies, and tax advantages. Imagine that it’s 10 to 15 years into the future, and you’ve secured your dream job. Which reasons or incentives to save money resonate the most with you? Explain your reasoning.
Answer:
Financial Freedom
Step-by-step explanation:
In my personal opinion, the biggest reason/incentive for saving would be Financial Freedom. This is the ability to not have to depend on a full-time job in order to survive and be able to live off of the passive income being produced by the money that you saved. If you save enough money and invest it correctly you can live off of the interest that is being generated from those investments. This allows you to not have to work a full-time job and instead free's up your time to pursue meaningfull hobbies or even travel. I believe that is true freedom and it is something that motivates me to save money.

Which of the following is the maximum value of the function y = −x^2 + 2x + 1?
Answer:
Step-by-step explanation:
We don't need choices to find out the correct answer. Solve this problem by completing the square. Begin by setting the quadratic equal to 0 and moving over the constant, like this:
[tex]-x^2+2x=-1[/tex] and factor out the -1 in front of the x-squared, since the leading coefficient HAS to be a 1:
[tex]-1(x^2-2x)=-1[/tex] Now take half the linear term, square it, and add it to both sides. Our linear term is -2. Half of -2 is -1, and squaring that gives us 1. So we add a 1 into both sides. But that -1 out front there on the left is a multiplier, so what we actually added in was -1(1) which is -1:
[tex]-1(x^2-2x+1)=-1-1[/tex]
On the left side we have a perfect square binomial, which is why we do this, and on the right side we have -2:
[tex]-1(x-1)^2=-2[/tex] and we can move that constant back over and set the quadratic back equal to y:
[tex]y=-1(x-1)^2+2[/tex] which gives us a max height of 2.
(If this was modeling parabolic motion, we would know that the time it takes to get to that max height is 1 second. The vertex of this parabola is (1, 2))

The function ƒ(x) = 6x is vertically shrunk by a factor of ½ and translated 9 units in the negative y- direction. Select the correct graph of the resulting function.
Answer:
option C.
Step-by-step explanation:
since the graph y = 6x is shrunk by a factor of ½
it becomes y = 3x
to find one coordinate of this graph we put x = 1 so that we get y = 3
so one point we have is (1, 3).
and the other point is origin
[ for if you keep x = 0 then 3 × 0 = 0 so y comes 0 too.]
now this graph is translated 9 units in the negative y direction
so the point that initially was (0, 0) now becomes (0, -9).
we see that the only graph passing thru (0, -9) is C.
so the answer is option C.

sum of two dice, given that at least one of the dice must show a 6?
A. 4/11
B. 7/11
C. 9/11
D. 2/11
Answer:
The correct answer is D. 2/11.
Step-by-step explanation:
To determine what is the probability of rolling a number less than or equal to 8 with the sum of two dice, given that at least one of the dice must show a 6, the following calculation should be performed:
6 + 1 = 7
6 + 2 = 8

A) Over the interval [-2.5, 0.5], the local maximum is 2--------------------------
Hope it helps...
Answer:
(A) Over the interval [-2.5, 0.5], the local maximum is 2.
Step-by-step explanation:
"Over the interval [-2.5, 0.5], the local maximum is 2."
Correct. The local maximum is the maximum, or highest point, of the graph in a certain area of interval. In [-2.5, 0.5], the highest point is at the y-value of 2.
"As the x-values go to positive infinity, the function's values go to negative infinity."
Wrong. As the x values go to positive infinity (meaning they go to the right, or positive side of the graph), the function goes up, meaning the function's values go to positive infinity.
"The function is decreasing over the interval (-1, 0.75)."
Wrong. Only from [-1, 0] is where that area of the graph decreases. The other half of it, (0, 0.75), is where the graph increases.
"The function is negative for the interval [-2, 0]."
Wrong. Only from [-1, 0] is the function negative. In the interval [-2, -1], the function is positive.

[tex] {y}^{3a} \div {z}^{a} = {y}^{b} [/tex]
[tex] {y}^{3} \div z = {y}^{b \div a} [/tex]
[tex] {y}^{3 \div b} \div {z}^{1 \div b} = {y}^{1 \div a} [/tex]
[tex] {y}^{3 \div b} = {y}^{1 \div a} {z}^{1 \div b} [/tex]
[tex] {y}^{b} = {z}^{c} [/tex]
[tex]z = {y}^{b \div c} [/tex]
[tex] {y}^{3 \div b} = {y}^{1 \div a} \times ({y^{b \div c} })^{1 \div b} [/tex]
[tex] {y}^{3 \div b} = {y}^{1 \div a} \times {y}^{1 \div c} [/tex]
as b/c × 1/b = 1/c
and so we see based on the exponents that
3/b = 1/a + 1/c
