Answer:
x = 1
, y = 4
Step-by-step explanation:
Solve the following system:
{5 x + y = 9 | (equation 1)
10 x - 7 y = -18 | (equation 2)
Swap equation 1 with equation 2:
{10 x - 7 y = -18 | (equation 1)
5 x + y = 9 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{10 x - 7 y = -18 | (equation 1)
0 x+(9 y)/2 = 18 | (equation 2)
Multiply equation 2 by 2/9:
{10 x - 7 y = -18 | (equation 1)
0 x+y = 4 | (equation 2)
Add 7 × (equation 2) to equation 1:
{10 x+0 y = 10 | (equation 1)
0 x+y = 4 | (equation 2)
Divide equation 1 by 10:
{x+0 y = 1 | (equation 1)
0 x+y = 4 | (equation 2)
Collect results:
Answer: {x = 1
, y = 4
Answer:
The answer is 14.
5(3)-1 5 times 3 is 15 and 15-1 is 14.
Answer:
the slope is -3/2, and the y-intercept is 5/2.
Step-by-step explanation:
3x + 2y = 5
putting it into a y = mx+b form,
2y = -3x + 5
y = -3/2x + 5/2
the slope is -3/2, and the y-intercept is 5/2.
Answer:
h = √(44) ft
Step-by-step explanation:
Just looked back and A is actually the area because the unit was ft².
Area of a right isosceles triangle is half the area of a square.
A = ½S²
in this case your side is h.
A = ½h²
2A = h²
√(2A) = h
√(2(22)) = h
√(44) = h
plug that in your calculator for the answer.
16 and 24
Hope that helps!!!
