Answer:

B

Step-by-step explanation:

(5x - 2)² + 35x - 14 = - 12 ( factor out 7 from each term in 35x - 14 )

(5x - 2)² + 7(5x - 2) = - 12 ( add 12 to both sides )

(5x - 2)² + 7(5x - 2) + 12 = 0

Substitute m = 5x - 2 into the equation then in terms of m, the equation is

m² + 7m + 12 = 0 → B

Answer:

[tex]\huge\boxed{D)\frac{3p}{p-3} }[/tex]

Step-by-step explanation:

The first thing that can help you here is factoring every term.

[tex]p^2-4p-12[/tex]

Factor.

[tex](p-6)(p+2)[/tex]

[tex]6p+12[/tex]

Factor.

[tex]6(p+2)[/tex]

18p

Factor, keeping in mind the denominator of the other term.

[tex]6(3p)[/tex]

[tex]p^2-9p+18[/tex]

Factor.

[tex](p-6)(p-3)[/tex]

Now you have simplified your original problem:

[tex]\frac{p^2-4p-12}{6p+12} *\frac{18p}{p^2-9p+18}[/tex]

into:

[tex]\frac{(p-6)(p+2)}{6(p+2)} *\frac{6(3p)}{(p-6)(p-3)}[/tex]

Now, after multiplying the numerator and denominator of the fractions:

[tex]\frac{(p-6)(p+2)(6)(3p)}{(6)(p+2)(p-6)(p-3)}[/tex]

Then, you can simplify the fraction by cancelling terms:

[tex]\frac{3p}{p-3}[/tex]

Hope it helps :) and let me know if you want me to elaborate.

Answer:

y+3 = 1/2 (x-4)

Step-by-step explanation:

We can write the equation in point slope form

y-y1 = m(x-x1)

The slope is m and the point is (x1,y1)

y - -3 = 1/2(x -4)

y+3 = 1/2 (x-4)

Answer:

The perimeter of the Parallelogram is 20z + 16

Step-by-step explanation:

For a Parallelogram

Perimeter = sum of all sides

P = (7z + 3) + (7z + 3) + (3z + 5) + (3z + 5)

P = 7z + 7z + 3z + 3z + 3 + 3 + 5 + 5

P = 20z + 16

Thus, The perimeter of the Parallelogram is 20z + 16

Answer: No

Step-by-step explanation: To determine this, all we have to is plug our ordered pair into the equation for x and y.

Remeber that the first number is our x-coordinate and our second

number is our y-coordinate so we plug a 5 in for x and a 6 in for y.

So we have (6) = 2(5) + 7 or 6 = 10 + 7 or 6 = 17.

Since this is not a true statement, this point doesn’t satisfy the equation.

The 33rd term of the arithmetic sequence, 7,10,13.... is: 103

Recall:

The sequence, 7,10,13,... is an arithmetic sequence because:

13 - 10 = 10 - 7 = 3

Therefore, to find the 33rd term, substitute a = 7, n = 33, and d = 3 into an = a + (n - 1)d.

[tex]a_{33[/tex] = 7 + (33 - 1)3

[tex]a_{33[/tex] = 7 + (32)3

[tex]a_{33[/tex] = 103.
