Answer:
<4,22>.
Step-by-step explanation:
This question involves the concepts of addition and scalar multiplication of vectors. It is given that the vector u = <-4, 1> and v = <-1, 6>. To find -2u, simply multiply -2 with the elements of u. This will give:
-2u = <-4*-2, 1*-2> = <8, -2>.
Similarly:
4v = <-1*4, 6*4> = <-4, 24>.
Hence,
-2u + 4v = <8, -2> + <-4, 24> = <8-4, -2+24> = <4,22>.
So the correct answer is <4,22>!!!
hi hun!
From what I understand, ill explain to the best of my knowledge so u understand!
First. off they asked for "proportionality" basically asking for the rate it's growing at or weeks its taking.
I see that:
Flower 1: 6 inches
Flower 2: 10 inches
Flower 3: 14 inches
The proportionality which these flowers are growing at is 4 inches every two weeks.
And I also see:
Week 3
Week 5
Week 7
When u look closer u can see that the weeks are divisible by the inches for each of the flowers and each answer u get is 2!
And also just by looking at the weeks which are 2 weeks separate if u count them.
Week 3 would be:
6/3=2
Week 5 would be:
10/5=2
Week 7 would be:
14/7=2
so the proportionality is 2! c:

Answer:
90
Step-by-step explanation:
1/5x+4=1/3x-8
add 8 to both sides and subtract 1/5x from both sides
4+8=1/3x-1/5x
12=5/15x-3/15x
12=2/15x
divide both sides by 2/15
12÷2/15=x
when dividing by a fraction, invert and multiply
12*15/2=x
90=x
CHECK:
1/5(90)+4=1/3(90)-8
18+4=30-8
22=22
