How do i do this and tell me how u got the answer

EastWind [94]

Substitute.
2x+(2x -15) = -3

4x -15 = -3
Add 15 to both sides

4x = 12

Divide by 4

X=3

2(3) + y = -3

6+y=-3
-6 from both sides
Y=-9

(3,-9)

g100num [7]

Answer:

Bag 2

Step-by-step explanation:

Given

Bag 1:

$14\ ounce = 3.50$

Bag 2:

$24\ ounce = 5.28$

Required

Which is a better buy

To get which buy is better, we first get the unit price of each bag.

$Unit\ Price = Amount/Size$

For bag 1:

$Unit\ Price = 3.50/14$

$Unit\ Price = 0.25$

For bag 2:

$Unit\ Price = 5.28/24$

$Unit\ Price = 0.22$

The best buy is the one with smaller unit price

Hence, bag 2 is better to buy

What is the area of this figure?

ludmilkaskok [199]

Answer:

$\large\boxed{\large\boxed{42 unit^2}}$

Explanation:

The figure is not a regular hexagon. It is an irregular hexagon.

Please, find attached the picture with the original question and the figure.

You can split the figure into two triangles and one rectangle.

The rectangle has dimensions: 7units × 4units, thus its area is 28 units².

Both the upper triangle and lower triangle have base 7 units and height 2 units.

Hence the area of each triangle is:

$area=(1/2)base\times height$

$area=(1/2)7units\times 2units = 7units^2$

Hence, the area of the hexagon is:

$28units^2+7units^2+7units^2=42units^2$

Can some one help me.

jarptica [38.1K]

Answer:

The slope is 3

Step-by-step explanation:

m = rise/run

m = (y2 - y1)/(x2-x1)

points: (0,-5), (1,-2)

m = ((-5) - (-2))/ ((0) - (1))

m = (-5 + 2)/ (-1)

m = -3/-1

m = 3
