X- int : (1,0)
y-int: (0,-2)
to find x-int plug in 0 for y
0= (x-1)2
Solve for x
2x-2=0
2x= 2
x=1
to find y-int plug in 0 for x
y=(0 - 1) 2
y= (-1)2
y= -2
252 square ft because you multiply.
Answer: 20 lawns
Multiply each by 5 times for 20 yay woo hoo
2y+8x=21
This is in standard form, lets convert to slope intercept form
slope intercept form : y = mx + b
2y + 8x = 21
-8x -8x
2y = -8x + 21
y = -4x + 21/2
Answer: m = -4
What is the smallest number divisible by 3, 4, 32 and 9?
You might want to try factoring these denominators and writing them in their factored form:
3, 2^2, 2^5, 3^2
Your LCD must include the following factors: 3^2 and 2^5, or 9 and 32. Multiplying these together results in the correct LCD 9*32=288.
Check: Is 288 divisible by 3? Yes. The quotient is 96.
Is 288 divisible by 4? Yes. Is 288 divisible by 32? Yes. Is 288 divisible by 9? Yes.
