36 is what percent less than 48?

REY [17]

36/48 divide both by 12... = 3/4= 75%
we want to know what percent less it is, so we need to subtract that answer from 100% to get the right answer
100-75 =25
25%

Circle A was translated 3 units to the left and 4 units up to create Circle B. Which rule describes the translation that was app

kifflom [539]

Answer:

$B = (x - 3, y + 4)$

Step-by-step explanation:

Given

Represent the coordinates of circle A with (x,y)

<u>Translation</u>

Left = 3 units

Up = 4 units

Required

Determine the coordinates of B

When a point (x,y) is translated by h units left, the new point is: (x - h, y)

When a point (x,y) is translated by b units up, the new point is: (x, y + b)

So, when circle A is completely translated to B, the new points of B is:

$B = (x - h, y + b)$

In this case:

$h = 3\ and\ b = 4$

So:

$B = (x - 3, y + 4)$

At the beginning of the year Monica puts a set amount of money into her health benefit account. Every month she withdraws $15 fr

Answer:

An equation in the slope-intercept form is:

$y = 15x+210$

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where m is the rate of change or slope and b is the y-intercept

Given

Let x represent the time in months

Let y represent the amount of money remaining in the account.

Given that every month Monica withdraws $15 from this account for her contact lenses

so, the rate of change or slope = m = 15

Given that after 3 months she has $255 left in her account.

i.e. (3, 255)

substituting $m = 15$ , $x = 3$ and $y = 255$ in the slope-intercept form to determine the y-intercept

$y = mx+b$

$255 = 15(3) + b$

switch sides

$15(3) + b = 255$

$45 + b = 255$

$b = 255 - 45$

$b = 210$

Thus, the y-intercept b = 210

Now, substituting $m = 15$ and $b = 210$ in the slope-intercept form of the line equation

$y = mx+b$

$y = 15x+210$

Hence, an equation in the slope-intercept form is:

$y = 15x+210$
