How would you plot (-9, 2)? Please include where you start and which direction do you move next and how much.

Answers

You would go on the x line and find where the negative numbers are first (since there is a NEGATIVE 9). The left side is the negative side. From there, you find number 9 (but don’t plot anything get, just remember where it is). Then you go up 2 (so find where the 2 is in y and go up that many). You don’t directly go over to the Y line.

You go left 9 and up 2. You then plot your point at that coordinate.

The factored form of a quadratic function is f(x)=(x-p)(x-q).The standard form of a quadratic function is fX)=ax^2+bx+c. The factored
form for a quadratic function tells us the x-intercepts of the quadratic function, while the standard form for a quadratic function tells us they
intercept of the quadratic function.
If p=2 and q=-3, use what you have learned about multiplying polynomials to
1) write the factored form of the quadratic function f(x)
2) write the standard form for the quadratic function f(x)

Answers

Answer:

(1) f(x)=(x-2)(x-3)

Jose's school is selling tickets to a choral performance. On the first day of ticket sales
the school sold 3 adult tickets and 7 child tickets for a total of $132. The school took
in $141 on the second day by selling 4 adult tickets and 7 child tickets. What is the
price each of one adult ticket and one child ticket?

Answers

Step-by-step explanation:

let x be the price of the adult ticket and y the price of child ticket

so

3x+7y=132

4x+7y=141

from the first equation 7y=132-3x

lets replaxe this from the second equation

4x+(132-3x)=141

4x-3x=141-132

x=9

so knowing that 7y=132-3x

7y=132-3*9

7y=105

y=105/7=15

so finaly the adult ticket cost 9 dollars and child ticket cost 15 dollars

e is 5 more than d.
f is 7 less than d.
Work out
e-f
Simplify your answer.

Answers

Answer:

12+2d

Step-by-step explanation:

e=5+d

f=d-7

e-f = 5+d-(d-7)

e-f = 12+2d

The solution of expression e - f is,

⇒ e - f = 12 + 2d

We have to given that,

e is 5 more than d.

And, f is 7 less than d.

Hence, It can be written as,

e is 5 more than d.

⇒ e = 5 + d

And, f is 7 less than d.

⇒ f = d - 7

So, We get;

e - f = (5 + d) - (d - 7)

Combine like terms,

e - f = 12 + 2d

Therefore, The solution of expression e - f is,

⇒ e - f = 12 + 2d

What is x equal to? And what is the scale factor?

Answers

Answer:

1. 225 km

2. 95 km

3. 412.5 km

Step-by-step explanation:

For this one, it is saying that for every 2 cm, that is 50 km. So if you look at 9 cm, you can divide that by 2 cm to get 4.5 cm, this is what you can multiply by 50 km to get 225. Or you can look at it this way, for every 1 cm, the actual distance is 25 km. Then you can multiply each value by 25 to get your answer. Whichever one works for you.
