System of equations:
y = 6x + 104
y = 10x + 60
Method : <span>Substitution
Since the both equation is equal to y, you can substitute one equation for the other equation's y:
</span>
y = 6x + 104
10x + 60 = 6x + 104
-6x -60 =-6x -60

Answer : It would take 11 days.
Answer: 4
Step-by-step explanation: Slopes that are perpendicular to each other are opposite reciprocals. So take the opposite of the sign, negative or positive. Then flip the numerator and the denominator. -1/4 goes to +1/4 goes to +4. Hope this helps!
Answer:
y = 7/2 x -2
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (-2 -5)/(0-2)
=-7/-2
= 7/2
We know the y intercept is -2 ( The x coordinate is 0)
Using the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
y = 7/2 x -2
X + x + 1+ x + 2 = -27
3x + 3 = -27
3x = -27 -3
x = -30/3
x = - 10
x + 1 = -10 + 1 = -9
x + = -10 + 2 = -8
