Step-by-step explanation:
Answer:
(0.5, 2)
Step-by-step explanation:
substitution method is when you substitute a variable for another
so, it is given that y=2x+1 and y=6x-1. so we know the 'y' value is equal since they are the same thing
hence:
y=2x+1
y=6x-1
2x+1=6x-1
4x=2
x=1/2
y=2
20(15x − 34)+9x
Multiply the bracket by 20
(20)(15x)=300x
(20)(-34)=-680
300x-680+9x
300x+9x-680 ( combine like terms)
Answer: 309x-680
Answer:
d= 66
Step-by-step explanation:
1- Calculate diameter of the circle
Answer:
C
Step-by-step explanation:
Since the triangle is right use the sine ration to find y
sin30° = 
= 
Multiply both sides by 8
y = 8 × sin30° = 8 × 
= 4 → C
