How can one determine the number of x-intercepts of the graph of a quadratic function without graphing the function?
Answer:
The easiest method is to find the x-intercepts of the quadratic function by substituting y=0 in the function and solving it to find the possible values of x. The number of all possible values of x is the number of x-intercepts of the graph.

What are the first five terms of the arithmetic progression with the first term 8 and common difference 7 , then find the 17th?.
Step-by-step explanation:
a1 = 8
a2 = 8 + 7 = 15
a3 = 15 + 7 = 22
a4 = 22 + 7 = 29
a5 = 29 + 7 = 36
an = an-1 + 7 = a1 + 7×(n-1)
a17 = 8 + 7×16 = 8 + 112 = 120

Which of the following numbers is proportional to 84/108?
1. 86/110
2.98/126
3.64/72
4.91/104
Proportional numbers are numbers with the same equivalent ratio
98/126 is proportional to 84/108
The number is given as:
[tex]Number = \frac{84}{108}[/tex]
Reduce fraction to the lowest term
[tex]Number = \frac{7}{9}[/tex]
Reduce 86/110 to the lowest term
[tex]Number = \frac{86}{110}[/tex]
Divide by 2/2
[tex]Number = \frac{43}{55}[/tex]
43/55 is not equivalent to 7/9
Reduce 98/126 to the lowest term
[tex]Number = \frac{98}{126}[/tex]
Divide by 14/14
[tex]Number = \frac{7}{9}[/tex]
7/9 is equivalent to 7/9.
Hence, 98/126 is proportional to 84/108

Answer:
The answer is 0.6
Step-by-step explanation:
I find it helpful to setup a Venn Diagram when dealing with these. This chart is pretty useful when dealing with set notation.
Then, you can set this up as a system of equations. So, based on your problem, we can setup the system like this:
x + y + z = 0.8
y + z = 0.5
y = 0.3
If you solve this, you will get:
x = 0.3
y = 0.3
z = 0.2.
To get P(A), you x and y to get x + y = 0.6

Billy and Karen are playing a billy and Karen are playing a game. They toss a coin that can land either heads or tails and a
spinner that can land on any of 8 equal regions. If a coin is tossed and the spinner is spun,
howmany possible outcomes are there?
The number of possible outcomes for both Billy and Karen = 32 possible outcomes.
A coin has head and tail and thus;
Number of possible outcomes of a coin toss = 2
Now, for the for the spinner, since there are 8 equal regions;
The number of possible outcomes of the spinner = 8
Now, since they are playing a game;
Number of possible outcomes for Billy for one toss of coin and one time of spinning the spinner = 8 × 2 = 16
Similarly;
Number of possible outcomes for Karen for one toss of coin and one time of spinning the spinner = 8 × 2 = 16
Therefore;
Total possible outcomes for both Karen and Billy = 16 + 16 = 32 possible outcomes.

When will Road to a killcam 100 come out?
Answer:T he first season of Black Ops Cold War has been underway for almost a month now. The game has been having great success since it released back in November. One aspect of the multiplayer that a lot of players were disappointed with, was the lack of a final killcam.
Step-by-step explanation:
Answer:
The final Killcam is a Call of Duty staple. Every player in the game can see who got the final elimination of the game, and how they did it. The randomness is part of the fun; sometimes you’ll see an insane 360 Tomahawk kill, or you can have a good laugh at someone missing all of their shots before finally getting the elimination.
However, Black Ops Cold War has opted for a ‘Best Play’ system. Most of the time, you’ll see someone get a multi-kill from some point in the match. While you do often see impressive plays, the fun randomness element is mostly taken out and this has had a negative impact on Search and Destroy.
A Treyarch developer has now confirmed that they will be adding the final Killcam system to Cold War’s S&D in the future.

A small tree was planted at a height of 8 feet. The tree has been planted for 15 months, and is now 50 feet tall. Which equation could be used to find x, the average number of feet the tree grew each month?
Answer:
y=42/15x+8
Step-by-step explanation:
We can get the change in height with 50-8, or 42. Now we divide, so 42/15. I'm assuming this is a slope question, so it would be y=42/15x + 8. Let me know if this is the way you want the answer.
