Answer:
- see attached for a graph
- solution: (x, y) = (-1, 3)
Step-by-step explanation:
The first line has a slope of -3 and a y-intercept of 0. It will go through the origin and the point (-1, 3).
The second line has a slope of 1 and a y-intercept of 4. It will go through the points (0, 4) and (-4, 0).
The solution to the system of equations is the point where the lines cross, (-1, 3).

Answer:
you are correct
Step-by-step explanation:
0.09 = 0.00 because 0 in the tenths is nearer to the 0 than the next number or digit :)
Answer:
x = 17 / sqrt (2)
Step-by-step explanation:
first we have to notice that we have a right triangle, this means we can apply Pythagoras
h^2 = c1^2 + c2^2
then we just have to put the values we have and solve the equation
17^2 = x^2 + x^2
289 = 2(x^2)
289/2 = x^2
√289/2 = x
√289 / √2 = x
17 / √2
17 / sqrt (2)
