If y varies inversely with x, then we know that:

y = k/x

We are given x and y, so plug in the numbers and solve for k.

1.5 = k/6.4

k = 1.5*6.4

k = 9.6

Choose the equation below that represents the line passing through the point (−2, −3) with a slope of −6.
lubasha [3.4K]
Y = mx + b
slope(m) = -6
(-2,-3)...x = -2 and y = -3
now we sub....we r looking for b, the y int
-3 = -6(-2) + b
-3 = 12 + b
-3-12 = b
-15 = b

so ur equation is : y = -6x - 15

eduard

Let's factor x^2−22x+121

The middle number is -22 and the last number is 121. Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks? We need two numbers that...

Add together to get -22

Multiply together to get 121

Can you think of the two numbers?

Try -11 and -11:

-11+-11 = -22

-11*-11 = 121

Fill in the blanks in

(x+_)(x+_)

with -11 and -11 to get...

(x-11)(x-11)


Answer: (x-11)(x-11)


Hope this helps!!!

One of the roots of the equation x²-5x +q=0 is 2. Find the other root and the value of the coefficient q.
yuradex [85]

Answer:

Other root: x=3

q=6

Step-by-step explanation:

If x=2, then x-2=0.

Therefore:

x^2-5x+q=0

2^2-5(2)+q=0

4-10+q=0

-6+q=0

q=6

This means that the other root is x=3 since (x-2)(x-3)=x^2-5x+6
