8 pieces = 360°
1 piece = 360 ÷ 8 = 45°
Answer: The last piece measures 45°.
Answer:
x=1, y=4
Step-by-step explanation:
x+y=5 - (1)
y=3x + 1 (2)
Sub (2) into (1)
x + (3x +1)=5
4x=5-1
x=4 ÷4
=1
Sub x=1 into (2)
y=3(1)+1
= 4
Answer:
The value of the z is 12 .
Step-by-step explanation:
Definition of vertically opposite angle .
Vertically opposite angles is defines angles opposite to each other when two lines cross eachother .
Thus
(5z + 8)° = (4z + 20)°
(5z + 8) = (4z + 20)
Open the bracket
5z + 8 = 4z + 20
5z - 4z = 20 -8
z = 12
Therefore the value of the z is 12 .
Answer:
Option A
Step-by-step explanation:
Domain is the set of x values or input values of a function.
Range is the set of y values or output values of a function.
Given relation is,
2x + y = 4
Set if input values of domain → {-5, 0, 6}
Table for the input - output values,
x -5 0 6
y 14 4 -8
Therefore, range of the given relation will be the set of output values.
{14, 4, -8}
Option A is the answer.
