The idea for transitions for an equation like this is
where m = slope
h = how much left or right (note the negative)
k = how much up or down
moving 13 down would mean
k = -13
so
D. would be your answer
Answer:
<em>A) 84x-16y-10.6</em>
2(14x-3y+28x+12.2-5y-17.5)
2(48x-3y+12.2-5y-17.5)
2(48x-8y+12.2-17.5)
2(48x-8y-5.3)
<em>84x-16y-10.6</em>
A quadratic equation is of the format:
ax² + bx + c = 0, where a ≠ 0.
The first option is not quadratic, it is a cubic, it has highest power of 3.
The second option f (x) = 3/4 x ^2 + 2x − 5, is quadratic, that is the answer.
The third f(x) = 4/x^2 - 2/x + 1, doesn't qualify because of the 2/x.
The last f(x) = 0x^2 − 9x + 7
, doesn't qualify because of the a = 0, and the rule is that a ≠ 0.
Therefore f (x) = 3/4 x ^2 + 2x − 5 represents a quadratic function.
I hope this helps.
The total number of cars both the student and the teacher made is 49
let
total cars = x
cars made by student = s
cars made by teacher = t
Total = student + teacher
x = s + t
s = 2/7x
So,
x = 2/7x + t
x - 2/7x = t
t = (7x - 2x) / 7
t = 5/7x
Similarly,
s = t - 21
s = 5/7x - 21
equate both s equation
2/7x = 5/7x - 21
2/7x - 5/7x = -21
(2x - 5x) / 7 = -21
- 3/7x = -21
x = -21 ÷ -3/7
= -21 × - 7/3
= (-21 × -7) / 3
= 147/3
x = 49
Therefore, the total number of cars both the student and the teacher made is 49

Answer:
Kindly check explanation
Step-by-step explanation:
The number of blue whales residing in a particular ocean is estimated to be four. Find the estimated amount of kills the blue whales would have consumed by the turn of the year.
Given that:
Amount of krills consumed per year = 1460000
Number of Blue whales = 4
Hence, the estimated consumption of the blue whales will be :
Number of Blue whales * estimated consumption per whale :
(4 * 1460000) = 5840000
Hence,
Estimated consumption of the Blue whales per year = 5.84 × 10^6
