Plane R and plane P intersect at AB.

Planes are when 3 points that are not on the same line can be used to describe a plane. Plane P is horizontal and Plane R is vertical and these 2 planes intersect at line AB. Intersecting is where these 2 planes meet, therefore line AB is common to both planes.

you got a new credit card with an interest rate of 18% compounded monthly and no minimum payment. you go on a shopping spree and

just olya [345]

The total amount owed after 6 months will be found using the formula:
FV=P(1+r/100*n)^n
P=principle=$10000
r=rate=18%
n=terms=0.5

FV=10000(1+18/2*100)^0.5
FV=$10,440.30651
Thus the amount owed will be $10440.30651

-3x -4y = 20 x - 10y =16 if (x, y) is the solution to the system of equations above what is the value of x?

balu736 [363]

Multiply first equation by -5 and 2nd by 2, add them

15x+20y=-100
<u>2x-20y=32 +</u>
17x+0y=-68

17x=-68
divide both sides by 17
x=-4

the x value is -4

P(x)=x^3+2x^2-4x-8 how do you factor this polynomial function

Wewaii [24]

<h2>Steps:</h2>

So for this, I will be factoring by grouping. Firstly, factor x³ + 2x² and -4x - 8 separately. Make sure that they have the same quantity inside of the parentheses:

$p(x)=x^2(x+2)-4(x+2)$

Now we can rewrite it as:

$p(x)=(x^2-4)(x+2)$

However, we aren't finished factoring yet. The first factor, x² - 4, can be factored further using the difference of squares. The difference of squares goes by the formula here: $x^2-y^2=(x+y)(x-y)$ . In this case:

$x^2-4=(x+2)(x-2)\\p(x)=(x+2)(x-2)(x+2)$

<h2>Answer:</h2>

<u>In short, the answer is $p(x)=(x+2)(x-2)(x+2)\ \textsf{OR}\ p(x)=(x-2)(x+2)^2$ </u>

Help please it’s my last questions

mihalych1998 [28]

Answer:

The one u highlighted is correct. C.

Step-by-step explanation:

If u substitute -2 to 2x, it is -4. then substitute the second one -2 to-5y, it is +10. -4+10=6. Then for the second thing. Substitute 1 to 2x which is 2*1=2. Then substitute-4/5 to -5y which is +4. 2+4=6.
