The entirety of 8 ducks as a fraction is 8/8.

So 2 ducks have blue wings which means that represents a quarter (25%) of the total ducks.

A quarter as fraction is 1/4.

Ex to understand de logic:

1/1 is a full (100%)
1/2 is a half (50%)
1/4 is a quarter (25%)

In our case 8/8 equals with 1/1 (100% of the ducks).

2/8=1/4 for me would be the fraction of ducks

What is the equation, in slope-intercept form, of the line that contains the points (3, -4) and (5 -6)
Alika [10]

Answer:

y = -x - 7

Step-by-step explanation:

As we move from the point (3, -4) to the point (5, -6), x increases by 2 and y decreases by 2.  Thus, the slope of this line is m = rise / run = -2/2, or -1.

Starting with the general slope-intercept form of the equation of a straight line, we get y = mx + b => y = -1x + b.

Subbing -4 for y and 3 for x, we get

-4 = -1(3) + b, which yields b = -1

Thus, the desired equation is

y = -x - 1

If q(x)=7x^2-1 find q(-9)
liq [111]

For this, we are just going to plug in -9 for every x and then solve the equation:


q(x)=7x^{2} -1


q(-9)=7(-9)^{2} -1


q(-9)=7(81)-1


q(-9)=566


Now we know that q(-9) is equal to 566.

1. b = $95.94 / 6
       = $15.99

    t = $15.99 / 20
      = $0.80

2. A: $1.28 / 8 = $0.16 per oz
    B: $1.68 / 12 = $0.14 per oz

State the domain and range of the following relation<br> x^2+y^2=16
Vlada [557]

The domain and range is  [-4, 4] and [0, 4]

<h3 /><h3>What is Domain and range?</h3>

The domain of a function is the set of values that we are allowed to plug into our function.

The range of a function is the set of values that the function assumes.

x² + y² = 16

y = √16 - x²

For domain under root should not be negative quantity,

16 - x²≥0

16≥x²

So, x≤4 or x≥4

Thus, the domain is  [-4, 4]

Range:

y is maximum at x=0, y=4

y is minimum at x=4, y=0

Thus, range = [0, 4]
