Use the equation y-y1 = m(x-x1). Slope = m which can be solved by taking the difference of y and dividing it by the difference of x. Therefore m = 6/-10 which simplifies to -3/5. Then plug m into the equation with either point so for example y-(-5) = (-3/5)(x-19). This then simplifies into y = (-3/5)x + (32/5) which is the final answer.

A teacher writes the function f(x)=3x^2-18x+27 on the board. How many times does the graph of the teacher's function intersect t
Oduvanchick [21]

Answer:

Once. at (3,0)

Step-by-step explanation:

It is handy to have a graphing calculator for this kind of question.

Otherwise work it out.

All the terms are multiples of 3, so simplify.3(x^{2} -6x + 9)

then factor (x -3)(x-3)

Set each equal to 0 and solve for x.

x - 3 = 0    x = 3

OH ! they are identical! So there is only One value for x that will produce an output of 0.

So it intersects (touches) only once.

What is the LCM of 12,30 and 42
Hoochie [10]

Answer:

420

Step-by-step explanation:

We can find the prime factors of each of the numbers first before finding their LCM.

12: <em>2</em> × 2 × <u>3</u>

30: <em>2</em> × <u>3</u> × 5

42: <em>2</em> × <u>3</u> × 7

To find the LCM, we need to see if they are any common prime factors between all three numbers. The common prime factors are <em>2</em> and <u>3</u>. Then, we multiply 2 and 3 with the remaining outstanding factors, which are 2, 5, and 7.

LCM: <em>2</em> × 2 × <u>3</u> × 5 × 7 = 420

Yuliya22 [10]

Your answer is the last option, 6.


We can work this out by looking for the total of people that like tennis in the table, and subtracting it from the total amount of people that like baseball.


This gives us a total of 46 people that like baseball, subtract 40 people that like tennis, and 46 - 40 = 6.


I hope this helps!
