Given the figure, we can deduce the following information:

1. Point A lies in the upper left side of the Cartesian Plane.

Based on the given figure, we must note that if the point lies in the upper left side of the Cartesian Plane or the x-coordinate is negative but the y-coordinate is positive, it should be in the Quadrant II.

Therefore, the answer is B. Quadrant II.

denis23 [38]

Answer:

3x + 3 = -2x + 3

3x + 2x = 3 - 3

5x = 0

x =0.

So y = 3(0) + 3 = 3.

Answer:

a. 1/2 + 9/10 = 5/10+9/10 = 14/10 = 7/5 = 1 2/5 meters or ribbon

b. 5/8 = 15/24, 7/12 = 14/24 Jeff jogged longer and by 1/24 kilometers

c. 3/9 = 6/18. 15/18-6/18 = 9/18 = 1/2 left.

Hope this helps :)

The probability that a house in an urban area will develop a leak is 55%. if 2020 houses are randomly selected, what is the pr

k0ka [10]

<span>The probability that a house in an urban area will develop a leak is 55%. if 20 houses are randomly selected, what is the probability that none of the houses will develop a leak? round to the nearest thousandth.

Use binomial distribution, since probability of developing a leak, p=0.55 is assumed constant, and
n=20, x=0
and assuming leaks are developed independently between houses,
P(X=x)
=C(n,0)p^x* (1-p)^(n-x)
=C(20,0)0.55^0 * (0.45^20)
=1*1*0.45^20
=1.159*10^(-7)
=0.000

Write as a product: ax^2+ay^2–bx^2–by^2+b–a

Vesna [10]

Answer:

$\large\boxed{ax^2+ay^2-bx^2-by^2+b-a=(a-b)(x^2+y^2-1)}$

Step-by-step explanation:

$ax^2+ay^2-bx^2-by^2+b-a\\\\=(ax^2-bx^2)+(ay^2-by^2)+(b-a)\qquad\text{use the distributive property}\\\\=x^2(a-b)+y^2(a-b)-1(a-b)\\\\=(a-b)(x^2+y^2-1)$
