Hi there! The answer is D.

To find our solution we must isolate y.

$2x + 5y = - 2$
First subtract 2x from both sides.

$5y = - 2x - 2$
Now we can divide both sides of the equation by 5.

$y = - \frac{2}{5} x - \frac{2}{5}$
Therefore, the answer is D. y=-2/5x-2/5

Let f(x) = x^2 + 6x.

Answer:

(A) The slope of secant line is 18.

(B) The slope of secant line is h+16.

Step-by-step explanation:

(A)

The given function is

$f(x)=x^2+6x$

At x=3,

$f(3)=(3)^2+6(3)=27$

At x=9,

$f(9)=(9)^2+6(9)=135$

The secant line joining (3,27) and (9,135). So, the slope of secant line is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{135-27}{9-3}=18$

The slope of secant line is 18.

(B)

The given function is

$f(x)=x^2+6x$

At x=5,

$f(5)=(5)^2+6(5)=55$

At x=5+h,

$f(5+h)=(5+h)^2+6(5+h)=h^2 + 16 h + 55$

The secant line joining (5,55) and $(5+h,h^2 + 16 h + 55)$ . So, the slope of secant line is

$m=\dfrac{h^2 + 16 h + 55-55}{5+h-5}$

$m=\dfrac{h^2 + 16 h }{h}$

$m=h+16$

The slope of secant line is h+16.

Answer:

Improper Fraction : $22/5

Decimal : $4.4

Mixed: $4 2/5 ...

Step-by-step explanation:

Sherman Has 3 cats and 2 dogs

Sherman has $22 to spend on pet toys.

To find the answer divide the overall amount that Sherman has to spend overall which is $22, Now divide it by the amount of pets that he has, 3+2=5

We can write it as:

Improper Fraction : $22/5

Decimal : $4.4

Mixed: $4 2/5 ....

Wen is factoring the polynomial, which has four terms.

Firdavs [7]

Answer:

2x(x + 3)(2x - 1)

Step-by-step explanation:

Given

4x³ + 10x² - 6x ← factor out 2x from each term

= 2x(2x² + 5x - 3) ← factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 3 = - 6 and sum = + 5

The factors are + 6 and - 1

Use these factors to split the x- term

2x² + 6x - x - 3 ( factor the first/second and third/fourth terms )

= 2x(x + 3) - 1(x + 3) ← factor out (x + 3) from each term

= (x + 3)(2x - 1)

Thus

4x³ + 10x² - 6x = 2x(x + 3)(2x - 1) ← in factored form
