Answer: 4/3
Step-by-step explanation:
You would find this answer because if x is 0 then it is just 2 then when you multiply 3 x 4/3 you get 4 then when you add that by two you get 6
Hopes this helps
Answer: A and B
Step-by-step explanation:
The shape is moving from right to left and down
Option A:
m∠B = 42.1°
Solution:
Given data:
b = 18, c = 15 and m∠C = 34°
Using sine formula:
Substitute the given values.
Do cross multiplication.
Divide by 15 on both sides.
Switch the sides.
m∠B = 42.1°
Option A is the correct answer.
4)
I:3x+4y=67
II:5x-y=35
to eliminate y when they are added one of the equations must contain -ay and the other +ay (with a being some number)
in this case we have in I already a positive term and in II a negative, but they have different numbers
by using multiplication (property of equations) we can multiply II by 4 so the negative and positive parts match
II*4: 20x-4y=140
when I and 4*II get added this results in
3x+20x+4y-4y=67+140
23x=207
5)
in this case I and II were added which can be seen in the left side of the equation((3x+4y)+(5x-y)=8x+3y), so to get the right side we have to also add the right sides 67+35=102
so the full equation would be:
8x+3y=102
