how to solve this? im not sure if i get the correct answer
Answer:
k = 3.5
Step-by-step explanation:
Area of a rectangle = length × width
Area of the bigger triangle - Area of the smaller triangle = 35 cm²
Thus:
(2k + 6)(k) - (3)(k) = 35 cm²
2k² + 6k - 3k = 35
2k² + 3k - 35 = 0
Factorise
2k² + 10k - 7k - 35 = 0
2k(k + 5) -7(k + 5) = 0
(2k - 7)(k + 5) = 0
2k - 7 = 0
2k = 7
k = 3.5
Or
k + 5 = 0
k = -5
The value of k would be the positive number which is 3.5.

It takes 1 4/5 minutes to fill an empty aquarium to a depth of 3/8 meters. What is the unit rate in minutes per meter? Write your answer as a fraction or a mixed number in simplest form.
Answer:
The filling speed of the aquarium is 1/5 meters per minute.
Step-by-step explanation:
Since it takes 1 4/5 minutes to fill an empty aquarium to a depth of 3/8 meters, to determine the unit rate in meters per minute, the following calculation must be performed:
4/5 = 0.8
3/8 = 0.375
1.8 = 0.375
1 = X
(1 x 0.375) / 1.8 = X
0.20 = X
0.20 = 1/5
Therefore, the filling speed of the aquarium is 1/5 meters per minute.

Matt was babysitting for friend's parents Saturday morning and was paid $10 per
hour for 3 hours. Later that evening, he was babysitting for another couple that paid
him $20 per hour for 5 hours. What was Matt's average rate of pay per hour for the
day?
Answer:
Matt was paid an average of $10 per hour of babysitting for the day.
Step-by-step explanation:
He babysat in the morning for 3 hours being paid $10 per hour. He later babysat in the evening for 5 hours being paid $20 per hour. Since he was being paid two different amounts throughout the day, the average would be $10. He was being paid atleast $10 per hour for babysitting because even though he was being paid $20 in the evening, the lowest amount of money that he was paid, was $10 making that the average.

write the equation of the parallel line that passes through (0,-3)
Answer:
y = 1.2x - 3 (slope intercept form)
or
5y-6x = -15 (standard form)
Step-by-step explanation:
Two parallel lines have the same slope, which means that our line's slope, will also be 1.2.
we can use the formula to find the equation of the line:
y-y1 = m (x-x1)
y1 - y coordinate of a point on the line
x1 - x coordinate of the same point on the line
m - slope
and we get:
y+3 = 1.2 (x-0)
y = 1.2x - 3 (slope intercept form)
or
5y-6x = -15 (standard form)

what type of transformation is described by (x,y) —> (x+2, y+16)?
This transformation takes a vector (x,y) and maps it to the vector (x+2, y+16). In other words, it moves the X coordinate of the vector 2 units to the right, and the Y coordinate of the vector is moved 16 units upwards.
If you would take a set of points and apply this transformation, you would see the entire set moving upwards and to the right, with no stretching ou rotating. This type of transformation is called a translation transformation.
