Answer:
Step-by-step explanation:
The only way this can be factored is by pulling out the GCF. 2 and x are common to both terms:
BUT you should also recognize that what's inside the parenthesis is the difference of perfect squares. And that factors to
(x - 10)(x + 10). So the complete factorization is
2x(x - 10)(x + 10)
Answer:
Step-by-step explanation:
Take the derivative of all terms with respect to x:
-2(dy/dx) + 16x = -7 + 18y(dy/dx). Grouping the (dy/dx) terms on the left, we get:
(dy/dx)(-2 - 18y) = -7 - 16x, or
-7 - 16x
dy/dx = ------------------
-2(1 + 18y)
Substituting 2 for x and -3 for y, we obtain the desired derivative:
-7 - 16x -7 - 32 -39
dy/dx = ------------------ = --------------- = ----------- = -0.368
-2(1 + 18y) -2(1 - 54) 106
Answer: 60
Step-by-step explanation:
Find the total number of students.
In this case, there are 8 total students. Multiply 60 * 8 = 480
Add all the numbers up.
85 + 65 + 36 + 48 + 75 + 39 + 72 = 420
480 - 420 = 60
x = 60
Answer:
The line goes through the origin
The line is sloping upwards
The x-intercept is 0

-2 and 2 are the x values of the coordinates which are 4 units apart, being 4 units in LENGTH
1 and -2 are 3 units apart and them being in the y part of the coordinate it’s 3 units wide
