Answer: m = 7 or -2

Step-by-step explanation:

Quadratic Formula! $\frac{{-b (+/-)\sqrt{(b^{2}-4ac }}}{2a}$

Polynomial Form: $ax^{2} +bx+c$

So in this example a: 1 b: -5 c: -14

You get: $\frac{{-(-5) (+/-)\sqrt{((-5)^{2}-4(1)(-14) }}}{2(1)}$

m = 7 or -2

Check by plugging a value back in for m

$(7)^{2} -5(7)-14=0?\\(-2)^{2} -5(-2)-14=0?\\$

True for both.

How do you solve for 2x-3y=6

lora16 [44]

2x+3y=6Simplifying 2x + 3y = 6 Solving 2x + 3y = 6 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3y' to each side of the equation. 2x + 3y + -3y = 6 + -3y Combine like terms: 3y + -3y = 0 2x + 0 = 6 + -3y 2x = 6 + -3y Divide each side by '2'. x = 3 + -1.5y Simplifying x = 3 + -1.5y

A horse takes 3 steps to walk the same distance for which a goat takes 4 steps. Suppose 1 step of the dog covers 1/2 of a metre.

almond37 [142]

Answer:

The goat would cover 9 meters in taking 24 steps.

Step-by-step explanation:

There is a mistake in the question so the correct question is below:

A horse takes 3 steps to walk the same distance for which a goat takes 4 steps. Suppose 1 step of the horse covers 1/2 of a metre. How many metres would the goat cover in taking 24 steps?

Now, to find the meters goat cover in taking 24 steps.

As 1 step of horse covers = $\frac{1}{2} \ meter.$
