To find slope intercept form, the formula is y=mx+b.
To find the slope, which is m, the formula is <span>(y2 - y1) / (x2 - x1)
y2=-26
y1=-20
x2=7
x1=5

(-26--20)/(7-5)
the slope is -3

now, to find the y intercept, solve for b.
y=-3x+b

</span>Step 1: Flip the equation.

<span><span>b−<span>3x</span></span>=y</span>
Step 2: Add 3x to both sides.

<span><span><span>b−<span>3x</span></span>+<span>3x</span></span>=<span>y+<span>3x</span></span></span><span>b=<span><span>3x</span>+<span>y

use your coordinates from the table.
b=3(5)-20
b=-5
so, y=-3x-5</span></span></span>

Y=-3x-5

x moves by -3, -3*5=-15
20-15=-5 (y intercept)

Someone help me out please
enot [183]

Hey there!

150 = 8x + 6y

↠ 150 = 8x + 6(9)

↠ 8x + 6(9) = 150

↠ 8x + 54 = 150

SUBTRACT 54 to BOTH SIDES

8x + 54 - 54 = 150 - 54

CANCEL out: 54 - 54 because that gives you 0

KEEP: 150 - 54 because helps solve for x

↣150 - 54 = 96↢

NEW EQUATION: 8x = 96

DIVIDE 8 to BOTH SIDES

8x/8 = 96/8

CANCEL out: 8/8 because that gives you 1

KEEP: 96/8 because that gives the value of x

96/8 = x

x = 12

Answer: x = 12

Good luck on your assignment and enjoy your day!

There are 6 rectangular flower gardens each measuring 18 feet by 17 feet in a rectangular city park measuring 80 feet by 160 fee
Aneli [31]

The area which is not in used for the flower gardens is 10964 sq ft.

Step-by-step explanation:

Given,

Length (l) of the rectangular park = 160 ft

Width (b) of the rectangular park = 80 ft

Length (l) of each rectangular flower garden = 18 ft

Width (b) of each rectangular flower garden = 17 ft

To find the area which is not in used.

Formula

The area of rectangle = l×b

Now,

The area of the rectangular park = 160×80 sq ft = 12800 sq ft

The area of each rectangular flower garden = 18×17 sq ft = 306 sq ft

The area of 6 rectangular flower garden =  306×6 sq ft = 1836 sq ft

So,

The area which is not in used = 12800-1836 sq ft = 10964 sq ft.
