Answer:

y=7/6x

Step-by-step explanation:

When given an equation and asked to find the equation of a perpendicular line that intersects it, you know that the slope is the slope of the equation is the negative recipricoal of the given equation. i.e. y=2x+2 and y=-1/2x+2. The y-intercept does not matter.

Mr.Ramirez had $600. He saved 3/5 and spent 3/8 of the remainder
Alex73 [517]

Answer:

$450

Step-by-step explanation:

Given function:

  • $600,3/5,3/8

To solve:

  • $600-3/5-3/8+3/5

Subtract the two terms:

  1. 600=\frac{30}{5}
  2. 600·\frac{3}{5}=360

Subtract the first value by 360:

  • 600-360=240

Find 3/8 of 240 and then subtract it:

  • 240·\frac{3}{8}=90

Combine the terms:

360+90=450

Therefore, Mr.Raminrez now have a total of $450..

Please help me ill mark you brainlyest
Len [333]

Answer:

A is false it said it could be greater than 35 or equal to and 100 x 5 = 500 + 1 = 501 therefore a is false

B is false 6.8 could be possible and it could be a decimal it can't only be a whole number

C is false 6 4/5 is a solution so c is false

D is I'm not sure, I think infinite except for 7 and below so maybe true

E is false because any number greater than 7 that are multiplied to 5 can be as long as its greater than or equal to 35

Ok this is what I think. Id rather wait for more answers to be sure thank you.
