Please solve this fast​
Korolek [52]

Step-by-step explanation:

1.

qr - pr \: + qs - ps

r(q - p) + s(q - p)

(r + s)(q  - p)

2.

{x}^{2}  + y - xy - x

{x}^{2}  -  x - xy + y

x(x - 1) - y(x - 1)

3.

6xy + 6 - 9y - 4x

- 4x + 6 + 6xy - 9y

2( - 2x + 3) - 3y( - 2x + 3)

(2 - 3y)( - 2x + 3)

4.

{x}^{2}  - 2ax - 2ab + bx

x(x - 2a) - b(x - 2a)

-(x +b)(2a-x)

5.

axy + bcxy - az - bcz

xy(a + bc) - z(a  + bc)

(xy  - z)(a + bc)

Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 poin
adell [148]
If AB and CD are parallel lines and PR is the transversal, then angle PRD = angle APR by alternate interior angle theorem.
Angle PRD = 120 degrees so,  65 + x = 120 degrees
120 - 65 = 55 degrees

What’s the equation in vertex form?
pshichka [43]

Answer:

\large\boxed{y=(x+5)^2-64}

Step-by-step explanation:

\text{The vertex form of equation}\ y=ax^2+bx+c:\\\\y=a(x-h)^2+k\\\\h=\dfrac{-b}{2a},\ k=f(h)\\\\\text{We have the equation:}\ y=x^2+10x-39\to x=1,\ b=10,\ c=-39.\\\\\text{Substitute:}\\\\h=\dfrac{-10}{2(1)}=\dfrac{-10}{2}=-5\\\\k=f(-5)=(-5)^2+10(-5)-39=25-50-39=-64\\\\\text{Finally:}\\\\y=1(x-(-5))^2-64=(x+5)^2-64

Solve the simultaneous equations<br> x-6y=5<br> xy - 2y2 = 6<br> -<br> Show clear algebraic working.
mojhsa [17]

Answer:

(- 7, - 2 ) , (9.5, 0.75 )

Step-by-step explanation:

Given the equations

x - 6y = 5 ( add 6y to both sides )

x = 5 + 6y → (1)

xy - 2y² = 6 → (2)

Substitute x = 5 + 6y into (2)

(5 + 6y)y - 2y² = 6 ← distribute and rearrange left side

5y + 6y² - 2y² = 6

4y² + 5y = 6 ( subtract 6 from both sides )

4y² + 5y - 6 = 0 ← in standard form

(y + 2)(4y - 3) = 0 ← in factored form

Equate each factor to zero and solve for y

y + 2 = 0 ⇒ y = - 2

4y - 3 = 0 ⇒ 4y = 3 ⇒ y = \frac{3}{4} = 0.75

Substitute these values into (1) for corresponding values of x

y = - 2 : x = 5 + 6(- 2) = 5 - 12 = - 7 ⇒ (- 7, - 2 )

y = 0.75 : x = 5 + 6(0.75) = 5 + 4.5 = 9.5 ⇒ (9.5, 0.75 )
