Answer:
x and y = 0
the question looks weird and almost wrong because when you subtract the equations, you are left with nothing
Step-by-step explanation:
Multiply the top equation by 3 to make the -x a -3x instead.
Then do the top equation - the bottom equation
At this point you should be left with x
Answer:
Step-by-step explanation:
First substitue the coordinates to the equation so
x=9, y=2
you would get
2=-3/7(9) + b
we put b because we are trying to find the new slope
multiply the two numbers above
2=-3/6/7 + b
subtract the whole number from both sides
b= 5/6/7
in equation would be
y= -3/7 + 5/6/7
Let me know if there is an error.
In y = mx + b form, the slope will be in the m position and the y int will be in the b position
y = -2x + 2....slope = -2 and y int = 2
y = -2x - 3.....slope = -2 and y int = -3
when u have 2 lines that both have the same slope but different y intercepts, u have parallel lines with no solution because ur lines never intersect.
so ur answer is : no solutions or 0 solutions
Unless you show a picture, its impossible to solve.
Answer:
BC ≈ 4.85 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° = 
= 
= 
( cross- multiply )
5.4 × cos26° = BC , then
BC ≈ 4.85 m ( to 3 s f )
