Answer:

x = -5

Step-by-step explanation:

-7x + 5(2x - 1) = -20 (Given)

-7x + 10x - 5 = -20 (Simplify)

3x - 5 = -20 (Simplify)

3x - 5 + 5 = -20 + 5 (Addition Property of Equality)

3x = -15 (Simplify)

\frac{3x}{3} = \frac{-15}{3} (Division Property of Equality)

x = -5 (Simplify)

which transformation causes the described change in the graph of the function y = cos x? the transformation results in a horizon
luda_lava [24]
The transformations that can occur to the graph of the function y = cos x that will exhibit changes would be changes to the angle, or changes to the coefficient. The transformations can be viewed as follows:

y = cos x transforms to y = cos (kx)

k > 1 ; a horizontal shrink occurs
0 < k < 1 ; a horizontal stretch occurs

y = cos x transforms to y = A cos x

|A| > 1 ; a vertical stretch occurs
|A| < 1 ; a vertical shrink occurs

The area of a rectangular dining room is 16 square meters. The perimeter is 16 meters. What are the dimensions of the dining roo
neonofarm [45]

Answer:

4

Step-by-step explanation:

The area is 16, and you know that it's 2 sides u need to multiply

The perimeter is 16, and you know that you need to add up all the sides

So....

A = b * h

A = 4 * 4

A = 16    CORRECT

And....

P = S + S + S + S                                                         ( s = sides)

P = 4 + 4 + 4 + 4

P = 16 CORRECT

Hope this helped!
