Answer:
The equation of the line would be y = -1/2x + 13/2
Step-by-step explanation:
In order to get the slope of the line, you need to first find the slope of the original line. You do this by solving for y.
2x - y = 8
-y = -2x + 8
y = 2x - 8
Now that you have the slope, we take the opposite and reciprocal slope to be the perpendicular (based on the definition of perpendicular lines). This means we take the opposite of 2 (which is -2) and then we flip the term (which means -2 becomes -1/2).
To find the slope-intercept form, we'll use our new slope of -1/2 and a point in point-slope form and solve for y.
y - y1 = m(x - x1)
y - 2 = -1/2(x - 9)
y - 2 = -1/2x + 9/2
y = -1/2x + 13/2
The middle value should be 4%.
The reason why is because if the value inside the parentheses was 1.00, it would be constant. 1.04 is equivalent to a positive change of 4%.
Also, it changes every 1 hour, instead of every 15 minutes, because the function is solving for variable t, which, in this context, represents the time in hours.
Answer:
0.624999999(repeating) so i would round it to 0.625 or 0.63 (both work and are rounded, its really up to wherever your teacher wants you to round it to if they want you to round it)
Step-by-step explanation:
2/3 x 1/2 (3/4 ÷ 2/5)=
simplify the parentheses (3/4 ÷ 2/5) to 1.875
2/3 x 1/2 x 1.875=
simplify 2/3 x 1/2 to 0.333333(repeating)
0.3333333333 x 1.875 = 0.6249999999(repeating)
round it to 0.625 or 0.63 (which ever one your teacher wants you to round it to)
