A
Answer:
63
Step-by-step explanation:
k=y/x
y/x=k
y=k×x
y=7×9
y=63
First, write the equation of the line containing the points <span>(2,-5) and (-3,2).
We can use 2 point form, or point-slope form.
Let's use </span>point-slope form.
the slope m is

, then use any of the points to write the equation. (ex, pick (2, -5))
y-(-5)=(-7/5)(x-2)
y+5=(-7/5)x+14/5
y= (-7/5)x+14/5 - 5 =(-7/5)x+14/5 - 25/5 =(-7/5)x-11/5
Thus, the lines are
i) y=-ax+4 and ii) y=(-7/5)x-11/5
the slopes are the coefficients of x: -a and (-7/5),
the product of the slopes of 2 perpendicular lines is -1,
so
(-a)(-7/5)=-1
7/5a=-1
a=-1/(7/5)=-5/7
Answer: -5/7
Answer:$39.75
First, we have to find out how much would it be for a 20 mile taxi ride. To do this, we have to multiply. 20 x $1.85= $37.00.
Lastly, you have to find out how much the cost will be with the initial charge. To do this, we have to add. $37.00+$2.75=$39.75.
Hope this answered your question!
M*10-m*2=8
10m-2m=8
8m=8
Divide both sides by 8:
m=8
Fill in the m's:
1*10-1*2=8
10-2=8
8=8
Hope this helps :)
