Answer:
k = 3.75
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, k. Divide -1.2 from both sides:
(-4.5)/(-1.2) = (-1.2k)/-1.2
-4.5/-1.2 = k
k = -4.5/-1.2
k = 3.75
3.75 is your answer for k.

Since both 2 and 5 are prime numbers, there are no multiples for the fraction 2/5.
Answer:
4 miles
Step-by-step explanation:
In 7 minutes he runs 1 mile
So in 28 minutes he runs 4 miles
<u>How did I get this answer?</u>
7×4=28
So 1×4=4
In ratios, when you times anything by something, you must do the same to the other part of the ratio.
An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x
Answer:
Step-by-step explanation:
Given that Darcie wants to donate minimum 3 blankets to donate to a homeless shelter. No of days left =60
No of days to complete one blanket = 1/(1/15) = 15 days
Hence in 60 days she has to complete ≥3 blankets
No of days she has to utilize for this will be ≥3(15)=45
No of days she can skip crocheting ≤15
Let x be the no of days crocheted and y no of days skipped
Then x+y≤60
See the graph attached as x axis for days crocheted and y for days skipped
No of blankets can be either 3 or 4.
