Solving a system of equation
x+5y=15
-3x+2y=6
1 answer:
Answer:
(0,3)
y=3
x=0
Step-by-step explanation:
x+5y=15
-3x+2y=6
solve the equation
x=15-5y
-3x+2y=6
substitute the value of x into an equation
-3(15-5y)+2y=6
distribute
-45-15y+2y=6
add 15 to 2
-45-17y=6
add 45 from both sides
17y=51
divide both sides by 17
y=3
substitute the value of y into an equation
x=15-5•3
multiply 5 to 3
x=15-15
subtract
x=0

Answer:
soln
A=(9,j)
x1=9,y1=j
B=(10,4)
x2=10,y2=4
slope=1
by using the fomulaof slope,
slope=y2-y1/x2-x1
1 =4-j/10-9
1 = 4-j/1
1=4-j
j=4-1
j=3
x²(x - 4)(2x + 5) = 0
x² = 0 or x - 4 = 0 or 2x + 5 = 0
√x = √0 or x = 4 or 2x = -5
x = 0 x =
