Answer:
Step-by-step explanation:
Instead, since the divisor is in the form of 
, use what is called Synthetic Division. Remember, in this formula, 
gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:
4| 1 −5 7 −12
↓ 4 −4 12
_______________
1 −1 3 0 →
You start by placing the 
in the top left corner, then list all the coefficients of your dividend [x³ - 5x² + 7x - 12]. You bring down the original term closest to then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an 
, the −1 [
] follows right behind it, and bringing up the rear, comes the 3, giving you the quotient of .

1 dozen = 12
3 dozen = 3 x 12 = 36
36/8 = 4.5
They need 4.5 times the amount:
4.5 x 1.5 teaspoons = 6.75 teaspoons ( 6 3/4)
Answer:
(-4,-2)
Step-by-step explanation:
first u should chose a variable to eliminate and i choose Y
y=5/2x+8-y=-1/4x-3
get a common denominator
5/2= 10/4
-1/4=-1/4
the equation i will change a little because we are subtracting
10/4x+8+1/4x+3
11/4x+11
solve for the remaining variable which is X
subtract 11 on both sides
0-11=11/4x+11-11
-11=11/4x
multiply both sides by 4/11
-11 times 4/11= 11/4x times 4/11
x=-4
then substitute the variable in one of the equations and i choose y=5/2x+8
5/2(-4)+8= y
-20/2+8= y
-10+8=y
y=-2
