Write the equation of a line through the point (7,-10) and
perpendicular to 5y + 3x = 15.

Answers

Answer 1

Step-by-step explanation:

In order to find the equation I used the following formula:

y - y1 = m ( x - x1)

P.s y1 & x1 are the coordinates of the given point

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)

Find the slope of the line that passes through the points (-7,-5) and (4, -3).

Answers

Answer:

y = (-2/9)x

Step-by-step explanation:

Rise over run so between (-7,-5) and (4,-3) it goes up -2 and over 9 so -2/9. Put this next to x and boom you have the slope equation.

3y - 4x = 9

y = 4/3x + 3

Answer:

the answer would be m=4/3

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 orchestra is selling bracelets to raise money. The director uses an equation to
calculate the amount of profit, P, made from selling b bracelets.
P = 3b - 200
How many b should the orchestra sell to make a profit of $1000?

Answers

Use the equation it’s gives you then just plug in the P and solve for b. Hope this helps!!

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)

(2) f(x)=x²-5x+6

Step-by-step explanation:

(1) f(x)=(x-p)(x-q)

   f(x)=(x-2)(x-3)

(2) f(x)=x²-3x-2x+6

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.

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

Given f(x) = 3x^2 - 6x + 2 find f(3)
