Is that supposed to be : y = -x^3 ??
<span>i have the same question </span>
<span>yes it is </span>
<span>so when you write x2 you mean x^2 and 2x is 2^x also ? </span>
<span>is it an exponent
sorry, need ponts
</span>
Derivating the equation:

So the slope of the tangent in the point (0,1) is:

Then, the slope of the normal (n) line in the point (0,1) is:
15 mins = 900 s
We need to find all common multiples of 18 and 42 less than or equal 900.
We'll find the least common multiple first.
18|2
9|3
3|3
1
42|2
21|3
7|7

Now, we nned to find all multiples of 126 that are less than or equal 900.
Those are 126,252,378,504,630,756,882. There are 7 of those.
Therefore the answer is
7.
Answer:
2 x 6 = 12
5 x 7 = 35
12/35
Step-by-step explanation:
<h3>
Answer: y = 5x + 7</h3>
Work Shown:
y - y1 = m(x - x1)
y - (-3) = 5(x - (-2))
y + 3 = 5(x + 2)
y + 3 = 5x + 10
y = 5x + 10 - 3
y = 5x + 7
The equation is now in slope intercept form y = mx+b with m = 5 as the slope and b = 7 as the y intercept. Plugging x = -2 into this equation will lead to y = -3.
Side note: parallel lines have equal slopes but different y intercepts.
