Answer below
Step-by-step explanation:
Expanded form : 20 + 8 + 0.6 + 0.03
Expanded form is a way of writing numbers to see the individual math value of digits.
Word form: twenty eight point six three.
HOPE THIS HELPED
Answer:
I believe it would be 1/2
Step-by-step explanation:
Because 6/6 is a whole. anywhere above 3/6 is closer to 1 whole.
wait...I messed up ;-;..... Now I'm am not sure what the answer is D:
I always second guess myself.
Answer:
-4
Step-by-step explanation:
Pick any two points, let's go with (-7, 21) and (-6, 17) to find slope:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (17- 21) / (-6 - (-7))
= -4 / 1
m = -4
---Extra info---
y-intercept using anyone point, let's use (-5, 13) and slope above:
y = mx + b
13 = -4(-5) + b
13 = 20 + b
b = -7
Equation of line:
y = mx + b
y = -4x - 7
Check:
(-7, 21)
y = -4x - 7
21 = -4(-7) - 7
21 = 21
(-4, 9)
y = -4x - 7
9 = -4(-4) - 7
9 = 9

Ok so lets say the first number is x and the second number is y we will use a system of equations to solve.
"Three times one number is twice the second" this equation is 3x=2y
"<span>Twice the first number is 3 more than the second number." this equation would be 2x=y+3
To solve for x, change the second equation to y= 2x-3 by simply subtracting 3 from y to get y by itself.
Plug 2x-3 in for y in the first equation
3x=2(2x-3) solve for x - distribute the 2
3x=4x-6 subtract the 4x from both sides
-x= -6 divide both sides by -1 to get rid of the -x
x=6 now plug this into x in any of the 2 equations and you will find y
2x=y+3
2(6)=y+3
12=y+3
9=y
first number is 6 second number is 9
