Answer:

y = (3/2)x - 5/2

Step-by-step explanation: 5 + 2x

-2x-3y=5, solved for y, is y = ------------- , with a slope of -2/3. A line

-3

perpendicular to this one has a slope which is the negative reciprocal of -2/3, that is, +3/2. Using the slope-intercept formula, we calculate the y-intercept of the line that is perpendicular to the given one and passes through (1/3, -2): y = mx + b => -2 = (3/2)(1/3) + b, or

-2 = 1/2 + b. Thus, b must be -2 1/2, or -5/2.

The desired equation is y = (3/2)x - 5/2.

Answer:

y - 3/2x = - 5/2

Step-by-step explanation:

we calculate the slope of -2x - 3y = 5, by rewriting in slope-intercept form:

- 3y = 2x + 5,

y = -2/3x - 5/3

slope = -2/3

perpendicular slope (negative reciprocal) = 3/2

So the perpendicular equation is in the form y = 3/2x + b. Provided this passes through the point (1/3, -2), let's substitute and solve for b:

-2 = 3/2(1/3) + b,

b = -5/2

In slope-intercept form we have the equation as y = 3/2x - 5/2. But it asks for it in standard form. Therefore it's y - 3/2x = - 5/2.

What dose 5h-2+9h equal explain☺

DerKrebs [107]

Start out by combining LIKE TERMS
5h-2+9h
in this case 9h and 5h are like terms so you would add both of those together.
9h+5h=14h
-2 has no like terms so we can't do anything with it our final answer would be:
14h-2

Answer:

Katherine invested $12,000

Step-by-step explanation:

Use formula

$I=P\cdot r\cdot t,$

where

I = interest,

P = principal,

r = rate (as decimal),

t = time (in years).

In your case,

t = 1 year,

r = 0.06 (or 6%)

P + I =$12,720, thus

$12,720-P=P\cdot 0.06\cdot 1\\ \\12,720-P=0.06P\\ \\12,720=P+0.06P\\ \\1.06P=12,720\\ \\P=\dfrac{12,720}{1.06}\\ \\P=\$12,000\\ \\I=\$12,720-\$12,000=\$720$

a share of stock in the bree medical supply company is quoted at 35 1/4. suppose you hold 20 shares of that stock, which you bou

erica [24]

Total number of stocks bought = 20
Rate at which each stocks were bought = 31 1/2
   = 63/2
Rate at which 20 stocks were bought = 20 * (63/2) dollars
   = 10 * 63 dollars
   = 630 dollars
Rate at which each stocks were sold = 35 1/4
   = 141/4 dollars
Rate at which 20 stocks were sold = 20 * (141/4) dollars
   = 5 * 141 dollars
   = 705 dollars
Then
Amount of profit made by selling 20 stocks = (705 - 630) dollars
      = 75 dollars
So the total amount of profit made is $75. The correct option in regards to the given question is option "D".
