Answer:

Step-by-step explanation:

Moving a coordinate left will subtract from the x coordinate (left 3 means subtract 3 from x coordinate)

Moving a coordinate right will add to the x coordinate (right 3 means add 3 to x coordinate)

Moving a coordinate down will subtract from the y coordinate (down 3 means subtract 3 from y coordinate)

Moving a coordinate up will add to the y coordinate (up 3 means add 3 to y coordinate)

Reflect means flip the sign of the corresponding coordinate

reflect over x axis flip the sign of x coordinate

reflect over y axis flip the sign of y coordinate

What is the width of todors area model? 10x exponent2 -5x 15

mafiozo [28]

Answer:

The width of the area model is equal to

$(2x^2-x+3)\ units$

Step-by-step explanation:

The complete question is

Todor was trying to factor 10x^2-5x+15 he found the greatest common factor of these terms was 5 what is the width

we know that

The area of a rectangular model is given by the formula

$A=LW$ ----> equation A

where

L is the length

W is the width

we have

$A=10x^2-5x+15$

Factor the expression

$A=5(2x^2-x+3)$

substitute the value of the Area in the equation A

$5(2x^2-x+3)=LW$

In this problem

The greatest common factor of these terms is the length (L=5 units)

we can say that the width is equal to (2x^2-x+3)

therefore

The width of the area model is equal to

$(2x^2-x+3)\ units$

slamgirl [31]

Answer:

Mix numbers: 11 2/5

Improper numbers: 57/5

Step-by-step explanation:

4/10 in 11 4/10 can be simplified into 2/5

Also, mixed numbers and improper fractions are the simplest forms

Thus the answer has two solutions, with the same value:

11 2/5 or 57/5

hope this helps!

Levart [38]

Your question is not complete however, I will input what is likely to complete it.

Question:

A caterer is making cookie trays for upcoming holiday parties. This morning she mad a 4 small trays and 4 large trays, which contain a total of 288 cookies. In the evening, she made 1 small tray and 3 large trays, which contain a total of 180 cookies. How many cookies do the different sized trays contain?

Answer:

Each small tray can contain 18 cookies, while each large tray can contain 54 cookies

Step-by-step explanation:

Let assign some variables by denoting S = small trays and L = large trays

In the morning; 4S +4L = 288 --eqn 1

In the evening; 1S + 3L = 180 --eqn 2

From eqn 2, S = 180 - 3L ---eqn 3

Substitute eqn 3 into eqn 1

4(180 - 3L) + 4L = 288

720 - 12L + 4L = 288

8L = 432

L = 432/8 = 54

L = 54

Substitute L = 54 into eqn 3

S = 180 - 3L

S = 180 - 3(54)

S = 180 - 162

S = 18

Therefore, each small tray can contain 18 cookies, while each large tray can contain 54 cookies.

Note:

Use this second part of this question (my framed part of the question) to complete yours. You should get your answer adequately.
