Look at side AB.
The slope is -1/4.

Look at side BC.
The slope is 4.

The product of -1/4 and 4 is -1. That makes segments AB and BC perpendicular and angle B a right angle. That makes triangle ABC a right triangle.

Answer:

See below

Step-by-step explanation:

$f(x)=3x^2+6x-24\\\\f(x)=3(x^2+2x-8)\\\\f(x)+3(9)=3(x^2+2x-8+9)\\\\f(x)+27=3(x^2+2x+1)\\\\f(x)=3(x+1)^2-27$

Here, we can see that the vertex of the parabola is $(-1,-27)$ when we compare to the equation $y=(x-h)^2+k$ with vertex $(h,k)$ .

A second point you could plot is the y-intercept, when $x=0$ :

$f(0)=3(0+1)^2-27\\\\f(0)=3-27\\\\f(0)=-24$

So, your y-intercept is $(0,-24)$ .

Emerson purchased a game that was on sale for 18% off. The sales tax in his county is 8%. Let y represent the original price of

djyliett [7]

Answer:

you get ten percent off but you didn't give the cost of the game

Step-by-step explanation:

The tax subtracts from the percent off, so 18%off - 8% sales tax =10% off

-18x-(-8y)=10 I think??? It's in standard form...
