Answer:

z=4

Step-by-step explanation:

You would distribute the negative sign outside of the parentheses and get:

2z-z+1=5z-15

Then combine like terms and get:

z+1=5z-15

Subtract 5z from both sides:

-4z+1=-15

Subtract 1 from both sides:

-4z=-16

Then divide both sides by -4:

z=4

Find the value of x. The diagram is not drawn to scale.
GarryVolchara [31]

Step-by-step explanation:

y = 180 \degree - 116 \degree = 64 \degree \\  \\ x = 360 \degree - (125 \degree + 72 \degree + 64 \degree) \\  = 360 \degree -261 \degree \\  = 99\degree \\ \\   \huge \red{ \boxed{\therefore \: x = 99\degree }}\\ \\

Thus, option C is the correct answer.

What will happen to the original shape if the scale factor is a less than 1 b greater than 1 C equal to 1?
Sunny_sXe [5.5K]

Original shape will contract when scale factor is less than 1 , expand when scale factor is greater than 1 and it doesn't change when scale factor is 1

A scale factor is a number that can be used to change the size of any geometrical figure or shape in relation to its original size. It is the ratio of the sizes of the original and dilated figures.

It is denoted by "k"

The magnitude of the scale factor is taken into account, and it cannot be zero. The scale factor has the ability to either increase or decrease the size of an object.

The basic formula for calculating the scale factor of a dilated figure is as follows:

Scale = dimension of preimage / dimension of image

According to the question,

(a) If scale factor is less than 1 , k < 1 then the original shape will contract means It's size will decrease

(b) If scale factor is greater than 1 , then image will enlarge and it would expand

(c) If scale factor is equal to 1 , then No change in shape nor in size
