Answer:
The equation would be y = -3x - 9
Step-by-step explanation:
Since we have the slope of 1/3, we know the slope of a perpendicular line would be -3. This is because perpendicular lines have opposite and reciprocal slopes. We can then use this and the point to solve in point-slope form.
y - y1 = m(x - x1)
y - 3 = -3(x + 4)
y - 3 = -3x - 12
y = -3x - 9
Answer:
x = 7
Step-by-step explanation:
Order of operations rules require that we do multiplication and division BEFORE addition and subtraction.
Let's start by simplifying the expression. Adding 15 to both sides results in:
8,000÷(28x+4) = 40.
Multiplying both sides by (28x + 4) results in the simpler:
8000 = 40(28x + 4).
Dividing both sides by 40 results in:
200 = 28x + 4, or
196 = 28x
Solve for x by dividing both sides by 28:
x = 7
Its A. 10^15 because, 10^18 x 10^-3 = 10^18-3 = 10^15
Answer:
6/5 = 1.2
Step-by-step explanation:
Slope= rise/run
rise (going from the lower point up to the line the other point is on)
Run (Going from the point on the left to the same line the point on the right is on)
rise=6
run=5
6/5= 1.2
The answer is
t=tuesd=5km
w=wednes=6.2km
T=Thurs=50m=0.05km
the total during those three days are= t+w+T=11.25km
