<span>You simply set them to equal each other and solve!
y=2x+5
y=4x-2
Due to logical assumptions, we can say that 2x+5=4x-8
+8
2x+13=4x
-2x 13=2x
/2 x=13/2,, or 6.5</span>

First of all, you need to simplify the expressions in order to know whether they are equal. Then, it all depends on the expression, after you simplify an expression, it will seem much easier to determine that. <span />

Consider the expansion of (x + 2y)^10. Determine the coefficients for the terms with the powers of x and y shown.

julsineya [31]

Answer with Step-by-step explanation:

We are given that an expression

$(x+2y)^{10}$

Binomial expansion o f $(x+y)^n$ is given by

= $nC_0 x^n+nC_1x^{n-1}y^1+nC_2x^{n-2}y^2+nC_3x^{n-3}y^3+... nC_n y^n$

a. We have to find the coefficient of $x^2y^8$

$(x+2y)^{10}=10C_0x^{10}+10C_1x^9(2y)+10C_2x^8(2y)^2+10C_3x^7(2y)^3+...+10C_{10}(2y)^{10}$

Term is $10C_8x^(2y)^8$

Coefficient = $10C_8\cdot 2^8$

b.Term in which $x^4y^6$ is $10C_6x^4(2y)^6$

Coefficient = $10C_4\cdot 2^6$

c.We have to find the coefficient of $x^5y^5$

Term is $10C_5x^5(2y)^5$

Coefficient = $10C_5\cdot 2^5$

Graph x > -1 on the number line

Verdich [7]

Number Line:

Closed Circles are used when signs are "≤" or "≥"

Open Circles are used when signs are "<" or ">"

The graph of x > -1 on a number line would be towards the right from -1 with open circle as the sign is ">"

Graph should look like this:

Please help! I’m on a timer :/

If you want to find out how Addision paid each month, you have to have 36, then divide 36 by 12, and the answer will give you 3. So Addison paid $3 every month.

Hope this Helped

27< 3+5x+4<br><br> “With a step-by-step explanation be specific”

Nataly [62]

Answer:

$27 < 3 + 5x + 4 \\ 27 < 7 + 5x \\ 27 - 7 < 5x \\ 20 < 5x \\5x > 20 \\ x > \frac{20}{5} \\ \boxed{x > 4}$

<h3><u>x>4</u> is the right answer.</h3>
