Answer:
B
Step-by-step explanation:
Hey There!
To solve this problem we have to combine like terms
[tex]7x^3-6x^3=x^3\\6x^2-8x^2=-2x^2\\-5x+10x=5x\\5-7=-2[/tex]
So our answer would be
[tex]x^3-2x^2+5x-2[/tex] (b)

Martin and Stacey are playing a game in which they will roll two dice and add the digits. If the sum of the digits equals 5, Martin wins. If the sum of the digits equals 9, then Stacey wins. What conclusion could you make about the game?
A. Stacey will never win as it is impossible to get a sum of 9.
B. Martin has a better chance of winning because his sum is higher.
C. The game is not fair and they should not play.
D. The each have the same chance of rolling their sum which makes the game fair.

−2x−y=6
8x+3y=−28
x= ?
I have trouble with these kinds of problems so a mini explanation would really help me out :)
Answer:
equation 2into minus 3 into equation 1
8x+ 3y= -28
-3x-3y=18
----------------
5x=10
x =2
put value of y in equation 2
8 into 2+3y=-28
16+3y= -28
3y= -28+16
3y= -12
y= -4

p(x)= 4x^3 -3x^2+5x-2
Answer:
p=4x^3−3x^2+5x−2/x
Step-by-step explanation:
Let's solve for p.
px=4x^3−3x^2+5x−2
Step 1: Divide both sides by x.
px/x=4x^3−3x^2+5x−2/x
p=4x^3−3x^2+5x−2/x
Answer:
p=4x^3−3x^2+5x−2/x

If sinA = cosB, what is the relationship between A and B if A is obuse angled and B is acute angled ?
Answer:
According to the law of sines, \dfrac{AB}{\sin(\angle C)}=\dfrac{AC}{\sin(\angle B)}
sin(∠C)
AB

sin(∠B)
AC
start fraction, A, B, divided by, sine, left parenthesis, angle, C, right parenthesis, end fraction, equals, start fraction, A, C, divided by, sine, left parenthesis, angle, B, right parenthesis, end fraction. Now we can plug the values and solve:
\begin{aligned} \dfrac{AB}{\sin(\angle C)}&=\dfrac{AC}{\sin(\angle B)} \\\\ \dfrac{5}{\sin(33^\circ)}&=\dfrac{AC}{\sin(67^\circ)}\\\\ \dfrac{5\sin(67^\circ)}{\sin(33^\circ)}&=AC \\\\ 8.45&\approx AC \end{aligned}

If nkf ~ lzf, find nf, please help me with this it’s due tmr!!!!
Answer:
NF = 25
Step-by-step explanation:
Since ∆NKF ~ ∆LZF, the ratio of their corresponding side lengths would also be the same.
This means that:
KF/ZF = NF/LF
KF = x + 3
ZF = 4
NF = 15 + x + 3 = x + 18
LF = x + 3
Plug in the values into the equation
(x + 3)/4 = (x + 18)/(x + 3)
Cross multiply
(x + 3)(x + 3) = (x + 18)(4)
x² + 3x + 3x + 9 = 4x + 72
x² + 6x + 9 = 4x + 72
x² + 6x + 9 - 4x - 72 = 0
x² + 2x - 63 = 0
Factorize to find x
x² + 9x - 7x - 63 = 0
x(x + 9) -7(x + 9) = 0
(x + 9)(x - 7) = 0
x + 9 = 0 or x - 7 = 0
x = -9 or x = 7
We'd use the positive value of x, which is 7.
Therefore, x = 7.
✅NF = 15 + (x + 3)
Plug in the value of x
NF = 15 + (7 + 3) = 15 + 10
NF = 25

Answer:
angles: ∠J≅∠P, ∠K≅∠M, ∠L≅∠N
sides: JK ~ PM, KL ~ MN, LJ ~ NP
Step-by-step explanation:
The similarity statement lists corresponding parts in the same order. For example, the first letter of one triangle designator corresponds to the first letter of the other triangle designator.
It is easy to list corresponding angles. Simply list them in the same order as they show up in the similarity statement.
angles: ∠J≅∠P, ∠K≅∠M, ∠L≅∠N
__
Likewise, corresponding segments are those between corresponding vertices. If a segment uses letter designations 2 and 3 in one triangle (KL), it will use letter designations 2 and 3 in the other triangle (MN).
sides: JK ~ PM, KL ~ MN, LJ ~ NP
_____
Additional comment
I sometimes find it easier to list the vertices vertically. Then I can see the correspondence more directly.

K . . M

The formula for the pythagorem theory
hi pls helpppppp. thank uuu :)
Answer:
-7/4
Step-by-step explanation:
Slope is (y₂ - y₁) / (x₂ - x₁)
Using this, plug in the values they give.
(6 - (-1)) / (-4 - 0)
Simplify.
7 / (-4)
-7 / 4
The slope is - 7/4, or -1 3/4 ( negative 1 and three fourths)

find a6 for an arithmetic sequence where a1=3x+1 and d=2x+6
Answer:
a₆ = 13x + 31
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
Here a₁ = 3x + 1 and d = 2x + 6 , then
a₆ = 3x + 1 + 5(2x + 6)
= 3x + 1 + 10x + 30
= 13x + 31
[tex] \frac{ {2}^{x + 2} - {2}^{ x + 3} }{ {2}^{x + 1} - {2}^{x + 2 } } [/tex]
I suppose you just have to simplify this expression.
(2ˣ⁺² - 2ˣ⁺³) / (2ˣ⁺¹ - 2ˣ⁺²)
Divide through every term by the lowest power of 2, which would be x + 1 :
… = (2ˣ⁺²/2ˣ⁺¹ - 2ˣ⁺³/2ˣ⁺¹) / (2ˣ⁺¹/2ˣ⁺¹ - 2ˣ⁺²/2ˣ⁺¹)
Recall that nª / nᵇ = nª⁻ᵇ, so that we have
… = (2⁽ˣ⁺²⁾ ⁻ ⁽ˣ⁺¹⁾ - 2⁽ˣ⁺³⁾ ⁻ ⁽ˣ⁺¹⁾) / (2⁽ˣ⁺¹⁾ ⁻ ⁽ˣ⁺¹⁾ - 2⁽ˣ⁺²⁾ ⁻ ⁽ˣ⁺¹⁾)
… = (2¹ - 2²) / (2⁰ - 2¹)
… = (2 - 4) / (1 - 2)
… = (-2) / (-1)
… = 2
Another way to get the same result: rewrite every term as a multiple of y = 2ˣ :
… = (2²×2ˣ - 2³×2ˣ) / (2×2ˣ - 2²×2ˣ)
… = (4×2ˣ - 8×2ˣ) / (2×2ˣ - 4×2ˣ)
… = (4y - 8y) / (2y - 4y)
… = (-4y) / (-2y)
… = 2
