solong [7]
1.) y= 2/3x
2.)y= -1x + 1
3.)y= 2x + 1
4.)y= -2/3x + 1
The structure of the formula is y = mx + b.
m is the slope.
slope is found by rise over run.
b is the y intercept.
which is found by where the line is on the y axis

Answer:

a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 2

Step-by-step explanation:

At Image I, we have vertex at point (3,-2), and the length of the left side is of 1 unit(from -2 to -3).

In the larger figure, this length is of 2 units, so the dilation has a scale factor of 2 units. The rotation, due to the coordinates changing, is of 90º counterclockwise(if it was across the x-axis, only the y coordinate would change, but on image II, both coordinates change).

So the correct answer is:

a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 2

Types of bonds are divided into three categories: good risk, medium risk, and poor risk. Assume that of a total of 11, 332 bonds
Alekssandra [29.7K]

Answer:

Probabilty of not poor= 0.75

Step-by-step explanation:

total of 11332 bonds.

7311 are good risk.

1182 are medium risk.

Poor risk

= total risk-(good risk+ medium risk)

= 11332-(7311+1182)

= 11332-8493

= 2839.

Poor risk = 2839

Probabilty that the ball choosen at random is not poor= 1 - probability that the ball is poor

Probability of poor = 2839/11332

Probabilty of poor= 0.2505

Probabilty that the ball choosen at random is not poor= 1- 0.2505

= 0.7495

To two decimal place= 0.75

How can you express (16 + 40) as a multiple of a sum of whole numbers with no common factor?
deff fn [24]
You would do 16 + 40 = (8 X 2) + (8 X 5) = 8(2 + 5)




Hope this helps best of luck :)
