Answer: The product of the above polynomials will be

\frac{4y}{y+3}

Step-by-step explanation:

Since we have given that

\frac{2y}{y-3}\times \frac{4y-12}{2y+6}

We need to solve the product of two polynomials :

\frac{2y}{y-3}\times \frac{4y-12}{2y+6}\\\\=\frac{2y}{y-3}\times \frac{4(y-3)}{2(y+3)}\\\\=\frac{4y}{y+3}

Hence, the product of the above polynomials will be

\frac{4y}{y+3}

Answer:

The value of given expression is \frac{4y}{y+3}.

Step-by-step explanation:

The given expression is

\frac{2y}{y-3}\times \frac{4y-12}{2y+6}

\frac{2y}{y-3}\times \frac{4y-12}{2y+6}=\frac{2y\times (4y-12)}{(y-3)\times (2y+6)}

\frac{2y}{y-3}\times \frac{4y-12}{2y+6}=\frac{2y\times 4\times (y-3))}{(y-3)\times 2\times (y+6)}

Cancel out the common factor (y-3) and 2.

\frac{2y}{y-3}\times \frac{4y-12}{2y+6}=\frac{4y}{y+3}

Therefore the value of given expression is \frac{4y}{y+3}.

Kate runs 2/3 of a mile on Mondays, Wednesday's and Thursdays. She runs 4/5 of a mile on Tuesday and Fridays. How many miles doe
padilas [110]

Answer:

Therefore, we conclute that Kate run 1 mile and 7/15 of a mile for the week.

Step-by-step explanation:

We know that Kate runs 2/3 of a mile on Mondays, Wednesdays and Thursdays. She runs 4/5 of a mile on Tuesday and Fridays. We calculate how many miles does Kate run during the week.  

Therefore, we get

\frac{2}{3}+\frac{4}{5}=\frac{10+12}{15}=\frac{22}{15}=1+\frac{7}{15}

Therefore, we conclute that Kate run 1 mile and 7/15 of a mile for the week.

A line goes through the points (5, -1) and (7, -5). What is a possible equation to a new line that is perpendicular?
Leya [2.2K]

<em>Ok, so you are given an equation in standard form, 5x+4y=2, and a point, (7, 5). You are being asked to write the equation for a line that is parallel to the equation in standard from, and that includes the point (7, 5).  </em>

<em> </em>

<em> </em>

<em> </em>

<em>First, let's start by finding the slope of your new line. We know that it needs to have the same slope as 5x+4y=2, because parallel lines have the same slopes. To do that, we need to put the equation into slope-intercept form (y=mx+b), which means we need to isolate the "y."  </em>

<em> </em>

<em> </em>

<em> </em>

<em>  5x+4y=2 </em>

<em> </em>

<em>-5x     -5x  (subtract 5x from both sides to move it to the right side of your equation) </em>

<em> </em>

<em>4y = 2 - 5x </em>

<em> </em>

<em>/4  /4  /4 (divide all the terms by 4 to get "y" by itself) </em>

<em> </em>

<em>y = (1/2) - (5/4)x  ... I suggest leaving your slope as a fraction. </em>

<em> </em>

<em> </em>

<em> </em>

<em>Now, we know that our slope, m , is going to be -(5/4).  </em>

<em> </em>

<em> </em>

<em> </em>

<em>Next, we are going to use our slope, -(5/4), and point, (7, 5), to find the b-value (y-intercept) of your new line. Let's plug in what we know: </em>

<em> </em>

<em> </em>

<em> </em>

<em>y = 5 </em>

<em> </em>

<em>m = -(5/4) </em>

<em> </em>

<em>x = 7 </em>

<em> </em>

<em> </em>

<em> </em>

<em>y=mx+b </em>

<em> </em>

<em>5=(-5/4)(7) + b  -> I plugged in what we knew for y, m, and x.  </em>

<em> </em>

<em>5 = -(35/4) + b  -> I multiplied the numbers in the numerator (5 x 7) to get 35/4 </em>

<em> </em>

<em>20/4 = -(35/4) + b -> I converted 5 into a faction with a denominator of 4 by multiplying by (4/4) </em>

<em> </em>

<em>+(35/4) +(35/4)  -> I add (35/4) to both sides to isolate b </em>

<em> </em>

<em>55/4 = b ... or b = 13.74 </em>

<em> </em>

<em> </em>

<em> </em>

<em>Answer:  </em>

<em> </em>

<em>m = -(5/4) </em>

<em> </em>

<em>b = 13.75</em>

if two dice are thrown together , what is the probability of getting an even number on one die and odd number on the other die ?
Veronika [31]

Answer:

1/2

Step-by-step explanation:

the probability of the die rolling an even number  =  the probability of the die rolling an odd number  =1/2

Let us name these  2  dice as  A  and  B

One die can roll an even and the other can roll an odd, in the following cases

A  rolls even and  B  rolls odd. The probability of this happening  =1/2×1/2

A  rolls odd and  B  rolls even. The probability of this happening  =1/2×1/2

∴  The required probability

=1/2×1/2+1/2×1/2

=1/4+1/4

=1/2
