Answer:
x < -1 or x > 9
Step-by-step explanation:

Add 3 to both sides.

Simplify.

Divide both sides by 10.

Simplify.

Apply absolute value rule: If
then
or 
or 

Add 4 to both sides.

Simplify.


Add 4 to both sides.

Simplify.

Combine the intervals.

In this item, it is assumed that since the pattern is cut out of the paper which is usually a rectangle then, the shape of the pattern is also rectangle. The perimeter of the rectangle is,
P = 2L + 2W
The area is equal to,
Area = L x W
If we assume that length and width are equal, in order to maximize the space.
1600 cm² = L x L
The value of L from the equation is 40 cm.
Answer:
would multiply everything by the common denominator of 4
-3/4m - 1/2 = 2 + 1/4m....multiply everything by 4 and u get :
-3m - 2 = 8 + m
that will get rid of the fractions....but u could multiply by -4 ...giving u :
3m + 2 = -8 - m
Step-by-step explanation:
Given:
The equation of the curve is:

To find:
The gradient (slope) of the given curve at point (2,7).
Solution:
We have,

Differentiate the given equation with respect to x.


Now we need to find the value of this derivative at (2,7).




Therefore, the gradient (slope) of the given curve at point (2,7) is 19.
