8.9 x 10^-5 in scientific notation
Answer:
Step-by-step explanation:
hello :
note :
Use the point-slope formula.
y - y_1 = m(x - x_1) when : x_1= -4 y_1= -14
m= 3 (parallel means same slope)
an equation in the point-slope form is : y +14 =3(x+4)
Answer:
x=6,y=-11
Step-by-step explanation:
y=-3x+7
x=-2y-16
Substitute the second equation into the first every place you see an x
y=-3(-2y-16)+7
Distribute
y = 6y+48 +7
Combine like terms
y = 6y +55
Minus 6y from each side
y-6y = 6y-6y+55
-5y = 55
Divide by -5
-5y/-5 = 55/-5
y = -11
Now we need to find x
x=-2y-16
x = -2(-11) -16
x =22-16
x = 6
x=6, y= -11
