Answer:
-6r - 2s
Step-by-step explanation:
Combining Like Terms like this
-4r + s-2r - 3 s <<<
-6r + s - 3 s
= -6r - 2s <<<
So y=mx+b
cost=m(number of pages)+b
cost=y
# of pages=x
so points are
(x,y)
(50,1.55)
(100,2.25)
(150,2.95)
(20,3.65)
so solve for slope/m you do (y₁-y₂)/(x₁-x₂) so
just use any for example
(1.55-2.25)/(50-100)=-0.70/-50=1 times 0.7/50=7/500= (to convet to decimal form) 14/1000=1.4/100=0.14/10=0.014/1=0.014
slpoe is 0.014
y=0.014x+b
input one of the points exg 50 for x and 1.55 for y and solve for b
1.55=0.014(50)+b
1.55=.7+b
subtract .7 from both sides
0.85=b
so the equation is
y=0.014x+0.85
which is C
Answer: B
Step-by-step explanation:
the inner product of (a,b) * (c,d) is ac + bd
= 4 * 6 + 8 * -3
= 24 - 24
= 0
since the inner product is equal to 0, the vectors are perpendicular
answer is b
Answer:
3,850 people are likely to vote for Mrs. Meekus.
Step-by-step explanation:
Given that Mrs. Meekus has a voting intention of 7 out of 10, that is, 70%, in the event that 5,500 people are going to vote in the elections, the voting intention for this candidate would be obtained through the following calculation:
5,500 x 0.70 = X
3,850 = X
Thus, if said voting intention is reproduced, Mrs. Meekus would be voted by 3,850 voters.
