K I will try my best

1) y+3=7/3(x+3)

2) y-0=3/4(x+4)

3) y-4=-5(x+1)

4) y-0=1/3(x-2)

5) y+4=-1(x-4)

6) y-4=-5/2(x+2)

7) y+1=-1/2(x+4)

Mrs. Dixon had 1/2 of a cherry pie leftover. She split the leftover pie evenly between her children, and each child got 1/6 of a

AVprozaik [17]

1/2 = 3/6
Each children got 1/6
3/6 - 1/6x = 0
3/6 = 1/6x

Michael and laura spent a combined 250 hours in the tutoring center. If Michael spent 40 more hours than laura did,how many hour

Andrej [43]

X + y = 250
y + 40 = x

x + y = 250
y = x - 40

x + y = 250
- x + y = - 40

2y = 210

y = 105

Laura spent 105 hours, and Michael spent 145 hours there

The partial factorization of x2 – 3x – 10 is modeled with algebra tiles. An algebra tile configuration. 1 tile is in the Factor

Anestetic [448]

2 positive unit tiles are needed to complete the factorization.

Given

The partial factorization of x^2 – 3x – 10 is modeled with algebra tiles.

<h3>Partial factorization;</h3>

Partial fractions are the fractions used for the decomposition of a rational expression.

When an algebraic expression is split into a sum of two or more rational expressions, then each part is called a partial fraction.

In the second line, we can see that first term 1 is labeled + x squared, second is labeled + 2x (two positive tiles above), then the 5 tiles below + x squared are labeled negative x, and the 10 tiles below the + x tiles are labeled negative.

The negative values are represented as tiles labeled below (negative tiles) while positive values are tiles labeled above (positive tiles).

Therefore,

The factorization is;

$\rm x^2-3x-10=0\\\\x^2+2x-5x-10=0\\\\x(x+2)-5(x+2)=0\\\\(x+2)(x-5)=0$

Hence, 2 positive unit tiles are needed to complete the factorization.

Which formula used in probability to find Independence question

qwelly [4]

Answer:

Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true. You can use the equation to check if events are independent; multiply the probabilities of the two events together to see if they equal the probability of them both happening together.
