Set up the equations to determine x and y.. help please

Amy is helping plan her school's new basketball court. The west edge of the basketball court is located on the line y = 2x + 5.

lord [1]

Answer:

Step-by-step explanation:

hello :

The east edge cannot intersect with the west edge so :

the west edge and The east edge are paralal same slope but the slope for the line y = 2x + 5 is : 2

so : the line could the east edge be located is : y= 2x+b b : no 5

Alyze the following special produ

Eddi Din [679]

Answer:

1) Solving the term $(3x + 5)(2x - 3)$ using F.O.I.L we get $\mathbf{6x^2+x-15}$

2) solving the term $(x + 2)(x - 13)$ using F.O.I.L we get $\mathbf{x^2-11x-26}$

3) Solving $(x+5)^2$ using square of binomial we get $\mathbf{x^2+10x+25}$

4) Solving $(x+5)^2$ using square of binomial we get $\mathbf{x^2-6x+9}$

Step-by-step explanation:

1) (3x + 5)(2x - 3). Solve using the F.O.I.L.

F.O.I.L stands for First, Outer Inner Last

We have $(3x + 5)(2x - 3)$

First: 3x(2x)

Outer: 3x(-3)

Inner: 5(2x)

Last: 5(-3)

Solving we get:

$(3x + 5)(2x - 3)\\=3x(2x)+3x(-3)+5(2x)+5(-3)\\=6x^2-9x+10x-15\\=6x^2+x-15$

So, solving the term $(3x + 5)(2x - 3)$ using F.O.I.L we get $\mathbf{6x^2+x-15}$

2) (x + 2)(x – 13). Solve using the F.O.I.L.

F.O.I.L stands for First, Outer Inner Last

We have $(x + 2)(x -13)$

First: x(x)

Outer: x(-13)

Inner: 2(x)

Last: 2(-13)

Solving we get:

$(x + 2)(x - 13)\\=x(x)+x(-13)+2(x)+2(-13)\\=x^2-13x+2x-26\\=x^2-11x-26$

So, solving the term $(x + 2)(x - 13)$ using F.O.I.L we get $\mathbf{x^2-11x-26}$

3) (x + 5)^2. Solve using the square of Binomial.

The square of binomial is: $(a+b)^2=a^2+2ab+b^2$

Solving:

$(x+5)^2\\=(x)^2+2(x)(5)+(5)^2\\=x^2+10x+25$

So, solving $(x+5)^2$ using square of binomial we get $\mathbf{x^2+10x+25}$

4) (x -3)^2. Solve using the square of Binomial.

The square of binomial used is: $(a-b)^2=a^2-2ab+b^2$

Solving:

$(x-3)^2\\=(x)^2-2(x)(3)+(3)^2\\=x^2-6x+9$

So, solving $(x+5)^2$ using square of binomial we get $\mathbf{x^2-6x+9}$

What is the result of rotating the point (x, y) 270 degrees clockwise?

Fed [463]

Answer:

270 Degree Rotation

Step-by-step explanation:

When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative.

On the first day of vacation, you read one-quarter of a novel. On the second day, you read half of the remaining pages. On the t

olga2289 [7]

A] Let the total number of pages be x, this is equivalent to 1/1
The fraction of novel read on the first day is 1/4
The remaining fraction of pages will be:
1/1-1/4=3/4
Fraction read on the second day:
1/2×3/4=3/8
The remaining fraction will be:
1-(3/8+1/4)
=1-5/8
=3/8
Thus the fraction read on the third day is 3/8:
therefore:
3/8 represents 108 hence:
x=(1/1)/(3/8)×108
x=288 pages

b] The number of pages read on the second day will be:
(total number of pages)×(fraction of pages read on the second day)
total number of pages=288
fraction read on the second day=3/8
hence number of pages read on this date will be:

=288×3/8
=108
