Answer:
3.75 or 15/4
Step-by-step explanation:
8x+5=35
Subtract 5 from the left side to cancel it out, do the same thing to 35.
8x=30
Divide 8x by 8 to get x alone, do the same thing to 30.
x=3.75, or once you simplify 30/8, you get 15/4.
1.667
Basically divide the number by 2
Answer:
Y = 2x+5 would be one solution. Y-4x=02 would also have one solution!
Step-by-step explanation:
Answer:
Substitute the slope and the coordinates of point P in the equation of the line y=mx+b and then solve for b in each equation
Step-by-step explanation:
we know that
The first step is calculate the slopes of these two lines. Remember that if two lines are parallel then the slopes are the same (m1=m2) and if two lines are perpendicular then the slopes is equal to m1*m2=-1
The second step is substitute the slope m2 and the coordinates of point P in the equation of the line in slope-intercept form y=mx+b and then solve for b in each equation
