10 times the sum of 1/2 of a number and 6 means 10(x/2+6)
is 8
=8
10((x/2)+6)=8
divide both sides by 10
(x/2)+6=0.8
minus 6 from both sides
x/2=5.4
times both sides by 2
x=10.8
Answer:
y = (-4/3)x + 4
Step-by-step explanation:
Let y = mx + b, be the equation of the line in slope intercept form where we need to find m and b.
Perpendicular to y = (3/4)x - 5, means that m = - (1 / (3/4) ) = - 4/3
So, at this point, y = (-4/3)x + b.
Crossing the x - axis at 3 means that (3, 0) is a point on the line, where we note that x=3 and y=0.
Thus, we plug in these values into the equation y = (-4/3)x + b, to get
0 = (-4/3)(3) + b
0 = -4 + b, so that
b = 4.
Hence, the answer is:
y = (-4/3)x + 4
The answer to this equation is x=-2.5
