How do you rewrite y=1-1/2 x in slope-intercept form?

Brrunno [24]

Slope-intercept form is y=mx+b. It looks like you already have most of the equation there. Just rearrange a little. From what I can tell, you have y=1 - 1/2x. Just move the negative 1/2x in front of the 1. You'll get y= -1/2x + 1. Hope this helped!

You are playing the duck pond game at the carnival! There are 20 ducks in the pond. Five of the ducks have blue dots on their be

GaryK [48]

Answer: Pt= 3/256

Step-by-step explanation:

For each round the probability of winning is:

Pw = number of blue dotted ducks/ total number of ducks

Pw= 5/20 ( since the duck is being replaced)

The probability of losing is:

Pl= number of ducks without blue dotted belly/ total number of ducks

Pl = 15/20

Therefore the probability of winning 3 times out of 4 is:

Pt= Pw× Pw×Pw×Pl

Pt= (5×5×5×15)/(20×20×20×20)

Pt= 1875/160000

Pt= 3/256

Goodluck...

Circle A has a center of (4,6) and a radius of 5, and circle B has a center of (1,0) and a radius of 15. What steps will help sh

AlekseyPX

For me, this is a strange question...

Any two circles are similar.

Step-by-step explanation:

When two figures are similar, they have the same shape, and the ratios of the lengths of their corresponding sides (segments) are equal.

Two circles have the same shape.

The radiuses are corresponding segments and the diameters are corresponding segments. The ratio of lengths radiuses and diameters are equal.

If you want calculate it, then.

Circle A: r₁ = 5, d₁ = (2)(5) = 10

Circle B: r₂ = 15, d₂ = (2)(15) = 30

r₂/r₁ = 15/5 = 3

d₂/d₁ = 30/10 = 3

r₂/r₁ = d₂/d₁

HELPS ASAP! Write an equation for each line.

ehidna [41]

Answer:

y = -x + 2

Step-by-step explanation:

for this problem, you need the equation of a line.

the equation for a line -----> y = mx + b

m = the slope ( $\frac{rise}{run}$ )
b = the y-intercept of the line

1) b is always the easiest to find! it's always where y = 0. when you look on the graph, you will see that when y = 0, x = 2. that's the y-intercept!

y = mx + 2

2) let's find the slope now! rise is how much the line increases or decreases (up or down), run is how far across the line moves (left to right).

- this line decreases 2 spaces and is moving left 2 spaces

- 2/2 = 1

y = 1x + 2 or y = x +2

3) the final step is seeing if this line is negative or positive. the way you can tell is if it increasing or decreasing. this line is decreasing and you can tell because it starts high in the left corner, and falls in the bottom right.

y = -x + 2

Aman obtained 410 marks out of 500 in cbse 12 grade examination while his brother Anish gets 536 marks out of 600 in 9 grade exa

Rama09 [41]

Answer:

Anish performed better than Aman.

Step-by-step explanation:

Given:

Marks obtained by Aman =410

Total marks = 500

We will first find the percentage of marks obtained.

To find the percentage of marks obtained we will divide Marks obtained by Total marks multiplied by 100.

framing in equation form we get;

Percentage of Aman = $\frac{410}{500}\times 100 = 82\%$

Also Given:

Marks obtained by Anish = 536

Total marks = 600

We will first find the percentage of marks obtained.

To find the percentage of marks obtained we will divide Marks obtained by Total marks multiplied by 100.

framing in equation form we get;

Percentage of Anish = $\frac{536}{600}\times 100 = 89.33\%$

Now we can see;

Percentage of Anish is greater than Percentage of Aman.

Hence Anish performed better than Aman.
