Answer:

i hope this helps since we not using the gradient formula but rather substitution

Step-by-step explanation:

y-int: (0;-2) ( the y intercept is also the c value)

y=mx+c

sub in a point

2=4m-2

4=4m

m=1

Answer:

$\frac{12 {z}^{ 3} {y}^{2} }{5 {x}^{ 2} }$

Step-by-step explanation:

We want to simplify:

$\frac{36 {x}^{ - 2} {y}^{2} }{15 {z}^{ - 3} }$

The trick is that when a negative index in the numerator comes to the denominator , it becomes positive.

The vice-versa is also true.

That is:

${a}^{ - n} = \frac{1}{ {a}^{ n} }$

and

${a}^{n} = \frac{1}{ {a}^{ - n} }$

We simplify to get:

$\frac{12 {z}^{ 3} {y}^{2} }{5 {x}^{ 2} }$

The last choice is correct.

What is the positive solution of x^2 – 36 = 5x

Radda [10]

Answer: 9

Step-by-step explanation:

The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus: x^2 - 36 = 5x x^2 - 5x - 36 = 0 x^2 + 4x - 9x - 36 = 0 x(x + 4) - 9(x + 4) = 0 (x - 9)(x + 4) = 0 x - 9 = 0 or x + 4 = 0 x = 9 or x = -4 Therefore, the positive solution of x^2 - 36 = 5x? is 9.
