Answer:
2 months
Step-by-step explanation:
started with 20, an added 30 each month so 30 plus 30 equals 60, 2 months add it to 20, 60 plus 20 is 80. other girl started with nothing and added 40 each month so 40 plus 40 equals 80. also 2 months
Answer:
no
Step-by-step explanation:
8*10=80, 1*10=10
80+10=90
8*11=88
88 does not equal 90 so no
x^2 + 2x + 8
First, we'll try using the AC method.
(Because the degree of the quadratic is 2, there are two solutions.)
We cannot split the term using the AC method.
We'll instead use the quadratic formula.
Plug in values.
(-2 +/- √4 - 32)/2
(-2 +/- √-28)/2
(-2 +/- i√28)/2
(-2 +/- 2i√7)/2
(-1 +/- i√7)
<h3>x = (-1 + i√7)</h3><h3>x = (-1 - i√7)</h3><h3>The two values of x are found.</h3>
Perpendicular to a slope of 1/2 is the negative reciprocal slope -1/(1/2) = -2.
y = - 2 x + b
y + 2 x = b
b = 4 + 2(6) = 16
y = -2x + 16
Check:
-2(6)+16=4 good
Answer: y = -2x + 16
Answer:
$1800 of joint production costs are allocated to each type of shotgun. That is $60 per shotgun.
Step-by-step explanation:
Equal numbers of shotguns of each type are produced in the joint process, so the joint process cost is allocated equally between the types. The allocation for each shotgun is ...
$3600/(30+30) = $60 . . . . allocated cost per shotgun of each type
