Answer:

B. (-2, 0) and (1, 0)

Step-by-step explanation:

The equation can be factored as ...

y = 2(x^2 +x -2) = 2(x +2)(x -1)

The x-intercepts are the values of x where y=0, so will be the values of x that make one or the other of the binomial factors zero:

x = -2

x = 1

Then the intercept points are (-2, 0) and (1, 0). . . . . . . . . matches choice B

Benny gets a job at a law firm with a salary of 70,000$ per year. After the first year, his salary increases to 73,000$. Over th
Morgarella [4.7K]
Hey there!

Part A-  The y-intercept would represent Benny's starting salary: b = 70,000.

The slope would represent Benny's annual raise: m = 3,000.


Part B- The y-intercept is b = 70,000.

The slope is m = 3,000.

<span>The equation representing Benny's annual salary at any given year is y = mx + b, or y = 3,000x + 70,000, where x is the number of years since Benny started the job.</span>

Use the Law of Sines to find mZY.
Scrat [10]

Answer:

Step-by-step explanation:

recall law of Sines   :) the same as before  Sin(A) /a = Sin(B) / b

[ when you see it a lot.. you'll remember it  :D ]

for this problem  Z =A=123  and a = 30

Y=B and b =14

Sin(123) / 30 = Sin(B) / 14

14 * 0.0279556 = Sin(B)

0.391379 = Sin(B)

arcSin(0.391379 ) = arcSin ( Sin (B) )

23.040 = B

Y = 23.0°

are you seeing how to do these?  so you could on a test?

The length of the rectangle is n-3, ok, the width is 2

the area of a rectangle is just length * width

\bf A=(n-3)(2)\implies \boxed{A=2n-6}&#10;\\\\\\&#10;\textit{to make some equivalent, let's use our good friend Mr 1}&#10;\\\\\\&#10;\textit{recall that }\cfrac{whatever}{whatever}=1\qquad \qquad \cfrac{same}{same}=1&#10;\\\\\\&#10;\cfrac{55}{55}\cdot 2n-6\implies \cfrac{55(2n-6)}{55}\implies \cfrac{110n-330}{55}&#10;\\\\\\&#10;or&#10;\\\\\\&#10;\cfrac{xyz}{xyz}\cdot 2n-6\implies \cfrac{xyz(2n-6)}{xyz}\implies \cfrac{2nxyz-6xyz}{xyz}

so, if you simplify either of those, you'd end up with 2n-6.

because same/same = 1, and 1 * anything, is just anything itself.

If f(x) = х2 – 2х + 3, thеn find<br> f(-3).
exis [7]

Answer:

\huge\boxed{\sf f(-3) = 18}

Step-by-step explanation:

\sf f(x) = x^2 - 2x + 3

<u>Put x = -3</u>

\sf f(-3) = (-3)^2 -2(-3) + 3\\f(-3) = 9 + 6 + 3\\f(-3) = 18
