Answer:

<u>Standard form</u>: -3x + y = 25

Step-by-step explanation:

y=mx+b

y = 3x + 25 ... you want to convert to standard form (Ax+By=C)

-3x -3x ... you want the variables on the left side of the equation

-3x + y = 25

We need to find an equation in the form $y=mx+b$ .

To find $m$ , we use the formula:
$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

We'll use the points $(0, 25)$ and $(4, 37)$ :
$m=\frac{37-25}{4-0}=\frac{12}{4}=3$

The value of $b$ (the y-intercept) is the value of $y$ when $x=0$ , which is 25.

So the equation is $y=3x+25$ (choice A).

For this case we must solve the following questions:

Question 1:

We should simplify the following expression:

$\frac {\frac {m ^ 2 * n ^ 3} {p ^ 3}} {\frac {mp} {n ^ 2}} =$

Applying double C we have:

$\frac {m ^ 2 * n ^ 3 * n ^ 2} {mp * p ^ 3} =$

By definition of multiplication of powers of the same base we have to place the same base and add the exponents: $\frac {m ^ 2 * n ^ 5} {m * p ^ 4} =$

Canceling common terms:

$\frac {mn ^ 5} {p ^ 4}$

Answer:

Option A

Question 2:

We should simplify the following expression:

$\frac {3xyz ^ 2} {6y ^ 4} * \frac {2y} {xz ^ 4}$

So, we have:

$\frac {3xyz ^ 2 * 2y} {6y ^ 4 * xz ^ 4} =\\\frac {6xy ^ 2z ^ 2} {6y ^ 4xz ^ 4} =$

Simplifying common terms:

$\frac {1} {y ^ 2z ^ 2}$

Answer:

Option D

Question 3:

We factor the following expressions to rewrite the experience:

<em> $r ^ 2 + 7r + 10$ : </em>We look for two numbers that multiplied give 10 and added 7:

$(r + 5) (r + 2)$

<em> $r ^ 2-5r-50:$ </em> We look for two numbers that multiplied give -50 and added -5:

$(r-10) (r + 5)$

<em> $3r-30 = 3 (r-10)$ </em>

Rewriting the given expression we have:

$\frac {(r + 5) (r + 2) * 3 (r-10)} {3 (r-10) (r + 5)} =$

We simplify common terms in the numerator and denominator we have:

$(r + 2)$

Answer:

Option D
