if the original value of x was negative then X the opposite sign version of X would have to be positive Princeton's if I start with x equals -3 then x equals -3 equals + 3 which is positive
A. Y=-0.2X+6.1.
B. It's wanting an X and Y table I guess. So week zero is 6.1. Week one is 5.9. Two is 5.7. Three is 5.5. Four is 5.3. Five is 5.1. Hope that's far enough.
Answer:
$66
Step-by-step explanation:
It can be convenient to assign a different variable to the amount of money each spent. We can call the amounts spent by Seedevi, Georgia, and Amy "s", "g", and "a", respectively.
The problem statement tells us ...
s = (1/2)g
s = a +6
s + g + a = 258
__
The problem statement asks for the amount Seedevi spent, so we need to find the value of s. It is convenient to write the other variables in terms of s:
g = 2s
a = s -6
Then the sum is ...
s + (2s) +(s -6) = 258
4s = 264 . . . . . . . . . . . add 6, simplify
s = 66 . . . . . . . . . . . . . .divide by 4
Seedevi spent $66.
Answer:
y= -8/11 x=-63/11
Step-by-step explanation:
Rewrite equation
Step: Solve6x+y=−10for y
Step: Substitute−6x−10 for y in 4x−3y=14
Step: Substitute −8
/11 for x in y=−6x−10
y= −62
/11 --- (Simplify both sides of the equation)
___________________________________________
y= -8/11
x=-63/11
Answer:
A. $2.25
Step-by-step explanation:
If you subtract $7.50 from $18.75 you get $11.25, then divide that by 5 and you'll get $2.25.
Hope this was useful.
