Answer:
The reason why it is incorrect to cancel the 4x in the numerator with the 4x in the denominator is because 4x is not a factor of both the numerator and the denominator
Step-by-step explanation:
The denominator of the rational expression, x^2 + 4x - 12 given above is a quadratic equation. It is not factorizable. If we factorize the numerator, 4x - 8, we would have
4 (x - 2).
This means 4x is not a factor of the numerator(4x - 8) and neither is it a factor of the denominator (x^2 + 4x - 12). This is the reason why it is incorrect to cancel the 4x in the numerator with the 4x in the denominator. The factors of the denominator can only be gotten by using the general formula for solving quadratic equations
I believe it’s 5, 2 you would just you 2,-2 as a line segment
The answer is 2 so the one that says the answer is 6 do not follow the order of "PEDMAS"
Answer:
The equation of the tangent at x=-6 is
Step-by-step explanation:
The equation of a circle with center (h,k) with radius r units is given by:
The given circle has center (-3,1) and radius 5 units.
We substitute the center and the radius into the equation to get;
To find the slope, we differentiate implicitly to get:
When x=-6;we have
or
From the graph the reuired point is (-6,-3).
We substitute this point to find the slope;
The equation is given by .
We plug in the slope and the point to get:
Answer:
16:36 = 32:72 = 12:27
Step-by-step explanation:
An easy way for me to solve this is to divide the first value by the second. If they turn out to be the same fraction, then they are equivalent.
Is 16:36 = 32:72?
Yes, because
Is 16:36 = 12:27?
Yes, because
Is 16:36 = 3:4?
No because
