-5x+3y=-6
9x-4y=1
try adding them together and get
9x-5x+3x-4y=1-6
4x-y=-5
multiply the equation by 3
12x-3y=-15
add this euation to -5x+3y=-6 and get
12x-5x+3y-3y=-6-15
7x=-21
divide both sides by 7
x=-3
subsitute x=-3 for x in any equation
9x-4y=1
9(3)-4y=1
27-4y=1
-4y=-26
divide both sides by -4
y=6 and 2/4 or 6.5
x=-3
y=6.5
Answer:
im guessing D
Step-by-step explanation:
Answer:
x = ±2√15
Step-by-step explanation:
x^2 = 60
x = ±√60
x = ±2√15
Slope intercept form
y = mx + b
P1 (5,11)
M = -1/2.
Y - y1 = m(X - X1)
Y - 11 = -1/2(X - 5)
Y - 11 = -1/2X + 5/2
Y - 11 + 11 = -1/2X + 5/2 + 11
Y = -1/2X + 5/2 + 11
Y = -1/2X + 5/2 + 22/2
Y = -1/2X + 27/2
Y = -1/2X + 27/2. I believe this is the equation of the line in slope intercept form. I basically used slope point formula y-y1 = m(X-x1), to find the new equation of the line, inputting the value of the slope along with the point the line would go through.
