Answer:

set two equation of line y=ax+b and y=cx+d

when these two lines are perpendicular to each other, then a*c=(-1)

set answer is y=ax+b

we can know that a=1/6

bring in a=1/6 and(-4,5)

5=(1/6)*(-4)+b

=>5=(-2/3)=b

=>b=5 2/3

answer is y=(1/6)x+5 2/3

KiRa [710]

Answer:

The value of x = 3.

Step-by-step explanation:

The ratio between length and width is given by:

\frac{L}{W}=\frac{5}{3}

Where:

  • L represents the new length
  • W represents the new width

Now, we know that each dimension is reduced by x inches, it means:

L=18-x

W=12-x

Then, we will have:

\frac{18-x}{12-x}=\frac{5}{3}

Finally, we just need to solve it for x.  

3(18-x)=5(12-x)

5x-3x=60-54

2x=6

x=3

<u>Therefore, the value of </u><u>x = 3.</u>

I hope it helps you!

ale4655 [162]

Answer:

5 cups of peanuts

Step-by-step explanation:

My reasoning is if 1/2 cup of raisins is 2 1/2 cup of peanuts, you basically double the amount. So 1/2 becomes 1 cup and 2 1/2 becomes 5 cups. So 5 cups of peanuts for 1 cup of raisins.
