Y= -3/2x-2 graph graph
evablogger [386]

Answer:

To graph (like the provided picture) you must understand y=mx+b. Your m would stand for your slope which you need to determine with rise over run. Rise over run can be done by finding a place where both the x and y values are lined up. (0,-2) can be used as an example from the picture. You then want to find the next point where the x and y values line up which (-2,1) can be used. Go up 3 units and go to the LEFT 2 times which makes this a negative run. The slope would then be represented as -3/2.

Your x value stands for your x-value moving up or down while you b value stands for your y-intercept which point (0,-2) is represented as. Y represents the y value after the equation is plugged in with x and solved.

5. Simplify the expression.<br> 5+4·(8 — 6)2<br> 013<br> O21<br> 036<br> 040
zvonat [6]

Answer:

21

Step-by-step explanation:

Use PEMDAS

P ---> Parenthesis

E ----> Exponents

M & D -------> Multiplication & Division

A & S ------> Addition & Subtraction

5 + 4*(8 - 6)² = 5 + 4*(2)²

                     = 5 + 4*4

                     = 5 + 16

                     = 21

Part B and #2 please 15 points
suter [353]

Answer:

See answers below

Step-by-step explanation:

Perimeter of a square = 4L

L sis the side length of the square

L = 5x^4y^2

perimeter = 4(5x^4y^2)

perimeter = 20x^4y^2

2) Length = 6x-10

Width = 4x+3

Area of rectangle = Length * Width

Area of rectangle = (6x-10)(4x+3)

Area of rectangle = 24x^2+18x-40x-30

Area of rectangle= 24x^2-22x-30

perimeter = 2(L+W)

perimeter 2(6x-10+4x+3)

perimeter = 2(10x-7)

perimeter  = 20x-14

Hence the perimeter of the rectangle is 20x-14
