Answer:

$\boxed {\boxed {\sf y=3x+12}}$

Step-by-step explanation:

The slope-intercept form of an equation is:

$y=mx+b$

where <em>m </em>is the slope and <em>b</em> is the y-intercept.

Let's evaluate each answer choice. The one in slope-intercept form will have the y variable isolated on one side of the equation.

A. 2x+3y=21: This is <em>not</em> is slope-intercept form. The y is not isolated.
B. y-7=3(x+4): Again, this isn't slope-intercept form. A 7 is being subtracted from y
C. y²=3x²-6: This also isn't correct. y is being squared.
D. y=3x+12: This choice is correct. The y is all alone on the left side of the equation.

The equation in slope-intercept form is <u>D. y=3x+12</u>

Answer:

<h3>x = -2</h3>

Step-by-step explanation:

$3[-x + (2 x + 1)] = x -1\\\\\mathrm{Expand\:}3\left(-x+\left(2x+1\right)\right):\quad 3x+3\\3x+3=x-1\\$

Collect like terms

$3x -x =-1-3$

Add similar elements

$2x = -4\\\\\mathrm{Divide\:both\:sides\:by\:}2\\\frac{2x}{2}=\frac{-4}{2}\\\\Simplify\\\\x = -2$

It takes Bruce 12 h to complete his training. It takes Oliver approximately 2 days, 2 h, and 15 min to complete his training. Ho

Bond [772]

Answer:

Oliver completed his training work in 50.25 hours

Step-by-step explanation:

we know that

$1\ day= 24\ hours$

$1\ hour=60\ minutes$

we have

$2\ days, 2\ h,\ and\ 15\ min$

<u><em>Convert days to hours</em></u>

$2\ days=2(24)=48\ hours$

<u><em>Convert minutes to hour</em></u>

$15\ min=15(1/60)=1/4=0.25\ h$

so

$2\ days, 2\ h,\ and\ 15\ min=(48)+(2)+(0.25)=50.25\ h$

therefore

Oliver completed his training work in 50.25 hours
