The correct answer is: [C]: " 11x⁹ − x + 15 " .

Explanation:
___________________________________________________
Given:
___________________________________________________
" (x⁹ − x + 8) + (10x⁹ + 7) " ; Simplify/ Add.
_______________________________________________________
We can rewrite this as:
" 1x⁹ − 1x + 8 + 10x⁹ + 7 = ?
→ {The "1" is implied; since "1", multiplied by any value, results in the exact same value.}.
Combine the "like terms" :
+ 1x⁹ + 10x⁹ = 11x⁹ ;
+ 8 + 7 = 15 ;
and we are left with: " − 1x " ; which we can rewrite as: " −x " ;
_________________________________________________
So, we can write our answer as:
_________________________________________________
→ " 11x⁹ − x + 15 " ;
→ which is: "Answer choice: [C]: " 11x⁹ − x + 15 " ;

So every value of x increases by 1, so the run would be 1
Every value of y decreases by 3, so the rise would be -3
The slope is rise/run = -3/1 = -3
The y intercept is 7
Slope-intercept equation is y= -3x+7
Answer:
(6,6) only goes with Line 2
(3,4) goes with neither
(7,2) goes with both
Step-by-step explanation:
Ok to decide if a point is on a line you plug it in. If you get the same thing on both sides, then that point is on that line. If you don't get the same thing on both sides, then that point is not on that line.
Test (6,6) for -5x+6y=-23.
(x,y)=(6,6) gives us
-5x+6y=-23
-5(6)+6(6)=-23
-30+36=-23
6=-23
So (6,6) is not on -5x+6y=-23.
Test (6,6) for y=-4x+30
(x,y)=(6,6) give us
y=-4x+30
6=-4(6)+30
6=-24+30
6=6
So (6,6) is on y=-4x+30.
Test (3,4) for -5x+6y=-23.
(x,y)=(3,4) gives us
-5x+6y=-23
-5(3)+6(4)=-23
-15+24=-23
9=-23
So (3,4) is not on -5x+6y=-23.
Test (3,4) for y=-4x+30.
(x,y)=(3,4) gives us
y=-4x+30
4=-4(3)+30
4=-12+30
4=18
So (3,4) is not on y=-4x+30.
Test (7,2) for -5x+6y=-23.
(x,y)=(7,2) gives us
-5x+6y=-23
-5(7)+6(2)=-23
-35+12=-23
-23=-23
So (7,2) is on -5x+6u=-23.
Test (7,2) for y=-4x+30.
(x,y)=(7,2) gives us
y=-4x+30
2=-4(7)+30
2=-28+30
2=2
So (7,2) is on y=-4x+30
(x,y) Line 1 Line 2 Both Neither
(6,6) *
(3,4) *
(7,2) *
(6,6) only goes with Line 2
(3,4) goes with neither
(7,2) goes with both
ANSWER
Find out the total deposit.
To proof
Let us assume that the total deposit be x.
As given
Nabora Nagamatus deposited a check for $ 299.45 and a check for 229.52.
He recieved $42 in cash.
than the equation is become in the form
x = 299.45 + 229.52 - 42
x = $486.97
therefore the total deposit be $486.97 .
Hence proved
Nope always even
because the resultant number can be expressed as 2*n and is thus even.
