the transformation (x, y) → (x, y- 4) , means the x-coordinate remains unchanged, while the y-coordinate has 4 subtracted from it, for example

the points on the diagram

A(1, 5 ) → A'(1, 5 - 4) → A'(1, 1)

B(4, 5) →B'(4, 5 - 4) → B'(4, 1)

C(4, 3) → C'(4, 3 - 4) → C'(4, - 1)

D(2, 2) → D'(2, 2- 4) → D'(2, - 2)

Is a positive integer raised to a negative power always positive?

Alexus [3.1K]

Yes the negative exponents would only affect it by fractions. Like x^-6
is the same thing is 1/x^6. It does not affect the integer with the signs.

Find length of each side

IgorLugansk [536]

Option b: 10 in, 18.5 in, 31.5 in.

Explanation:

The three sides of a triangle are $2y+1, 3y+5$ and $7y$

The perimeter of the triangle is $60 in$ .

Since, Perimeter = all sides of the triangle

Let us add all the three sides to determine the length of each side.

$Perimeter=2y+1+3y+5+7y$

Substituting the value of Perimeter and simplifying, we get,

$60=12y+6\\54=12y\\4.5=y$

Substituting $y=4.5$ in the three sides of the triangle $2y+1, 3y+5$ and $7y$ , we get,

$2y+1=2(4.5)+1=10 in$

$3y+5=3(4.5)+5=18.5 in$

$7y=7(4.5)=31.5 in$

Thus, the lengths of each side are 10 in, 18.5 in, 31.5 in.

Slope of (0,45) (6,33) (15,15)

Vladimir [108]

Answer:

The slope is -2

Step-by-step explanation:

Given

$(x_1,y_1) = (0,45)$

$(x_2,y_2) = (6,33)$

$(x_2,y_3) = (15,15)$

Required

The slope (m)

Slope is calculated as:

$m = \frac{y_2 -y_1}{x_2 - x_1}$

So, we have:

$m = \frac{33 -45}{6 - 0}$

$m = \frac{-12}{6}$

$m =-2$
