Answer:

(y^2+5y+25)

Step-by-step explanation:

(y^3 - 125) ÷ (y -5)

Factor the first term. This is the difference of cubes

a^3 – b^3 = (a – b)(a^2 + ab + b^2)

Let a=y and b = 5 (5^3 =125)

(y^3-125) = (y-5) (y^2+5y+25)

Substitute this back into the original equation

(y-5) (y^2+5y+25)

----------------------------

(y-5)

The y-5 term cancels

(y^2+5y+25)

Which exponential equation is equivalent to the logarithmic equation below? c = ln 2

Sophie [7]

$\text{A logarithmic lemma: } \\ \text{It follows that: } \log_a a = 1$
$\text{Following this property, we can see that: } a^{\log_{a} a} = a$
$\text{Furthermore, we can create more general properties: } a^{\log_a b} = b$

$c = \log_e 2 \Rightarrow e^{c} = e^{\log_e 2} \\ \text{Using our third property, we see that: } e^{c} = 2$
$\text{And finally, this works for any } \log_{a} b \left\{a > 0, b \in \mathbb{R}\right\}$

These are congruent angles. So they would be equal to each other. 6x=4x+50

2x=50

x=25°

The equation shows the relationship between x and y:

dedylja [7]

Slope is generally showed by a variable, the variable can be represented by any letter. In this case the variable is represented by x

so the slope is the number that comes before the x, so the slope of this equation is -8

So your answer is A
