Answer:
b) three terms
c) -1
d) 7
e) 4
Step-by-step explanation:
put the expression in decreasing exponent order with the constant at the end
-x⁴ - 2x + 7
With this format it is easy to find the leading coefficient which is the coefficient of the term with the highest exponent; in this case you only see a negative sign but every variable, if no other coefficient is present, has an invisible '1'
Answer:
6 : 1
Step-by-step explanation:
divide by 3 on both sides
18 ÷ 3 = 6
3 ÷ 3 = 1
6:1
Answer:
(2,7)
Step-by-step explanation:
We know that the change in x from A to M is -2, and the change in y is 1 -- we can simply double that and add that to A to get B, as M is halfway between A and B. Thus, (6,5)+(-4,2)=(2,7) as the coordinates of B
2x-3y=13
x+2y=-4
First times the second problum by 2.
2x-3y=13
2(x+2y=-4)
Your new problum is
2x-3y=13
2x+4y=-8
Now subtract both problums
2x-3y=13
-2x+4y=-8
------------------
-7y=-21
Now divde the -7 on both sides.
-7y=-21
/7 /-7
---------------
y=2
Now you want to substitute the y for the 2 in on of your problums.
x+2(2)=-4
Now mutiplie the 2 by the 2
x+4=-4
Now subtract the 4 on both sides to solve for x.
x+4=-4
-4 -4
--------------
x=-8
1 short ton = 2000 lbs
(1352 lbs)*(1 short ton)/(2000 lbs) = <em><u>0.676 short tons</u></em><u><em /></u><em><u /></em>
