Answer:
R= q+c over 5y
Step-by-step explanation: Good luck sweetie!!
Answer:
y = 2x+4
Step-by-step explanation:
slope (m) = 2
point (-1,2)
so,
b = 2-2×(-1) = 4
y = mx+b
or, y = 2x+4
Answer: -5
Step-by-step explanation: -3 , -4 , -5 is the third
Answer:
y=10x+99
Step-by-step explanation:
Find the negative reciprocal of the slope of the original line and use the point-slope formula y−y1=m(x−x1) to find the line perpendicular to x+10y=60.
Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i
