10 is the default base for a logarithm
log of 50 is equal to log base 10 of 50
Answer: D
Explanation:
The equation of a line in the point slope form is expressed as
y - y1 = m(x - x1)
where
m represents slope
x1 and y1 represents coordinates of the point that the line passes.
From the information given, the equation of the path of the old route is
y = 2x/5 - 4
Recall, the equation of a line in the slope intercept form is expressed as
y = mx + c
By comparing both equations,
slope, m = 2/5
If two lines are parallel, it means that they have the same slope. Given that the new route is to be parallel to the old route and will go through point (Q, P), then
m = 2/5
x1 = Q
y1 = P
The equation of the new route be
y - P = 2/5(x - Q)
Answer:
There is 1 solution (1,0)
Step-by-step explanation:
y = 3.5x − 3.5
y = −3.5x + 3.5
Add this system of equations together
y = 3.5x − 3.5
y = −3.5x + 3.5
-----------------------
2y = 0
y = 0
Substitute back in
0 = 3.5x - 3.5
Add 3.5 to each side
3.5 = 3.5x
Divide by 3.5
3.5/3.5 = 3.5x/3.5
1=x
There is 1 solution (1,0)
Answer:
n=2
Step-by-step explanation:
(-y + -2 ) + ( 3y + 6)
-y + 3y = 2y
2 + (-6) = -4
equals to ( 2y - 4)
of the shaded portion.
