Answer:

x = 1

Step-by-step explanation:

Subtract the right side of the equation and simplify:

9x -4 -6x -2(x +1) +5 = 0

9x -6x -2x -4 -2 +5 = 0 . . . . . eliminate parentheses

x -1 = 0 . . . . . . . . . . . . . . . . . . collect terms

x = 1 . . . . . . . . . . . . . . . . . . . . . add the opposite of the constant

_____

<em>Check</em>

Substitute the value of x where x is found in the equation.

9·1 -4 -6·1 = 2(1 +1) -5

9 - 4 - 6 = 2·2 -5

-1 = 4 -5 . . . . . true. The answer checks OK.

Dovator [93]

We know that they have:
2 entrences

now you have to multiply it:
$2*3*8*3=6*8*3=48*3=144$

There are 144 different ways that Anita and Terry can go from street level to the trains:)

I NEED HELP CUZ I DONT KNOW HOW TO DO THIS

mars1129 [50]

Area of rectangle = l*w
Area of triangle = (1/2)*l*w

Based on the figure:

Area of triangles = 2*(1/2)*l*w
= 2*(1/2)*24*14 = 336 cm^2

Area of side rectangles = 2*l*w
= 2*44*25 = 2200 cm^2

Area of bottom rectangle = l*w
= 44*14 = 616 cm^2

To find the total surface area, you would add all of the sides together:

336+2200+616= 3152 cm^2

Don’t be afraid to ask any questions, if you have any :D

Nookie1986 [14]

Answer:

1. y=5/2x+4

2. y=-7x-3

Y=mx+b is slope intercept form

Step-by-step explanation:

You have to add it in the slope intercept formula

2. M=-7 and B=-3

so y=-7x-3

M = 5/2 B = 4

So y = 5/2x+4
