Answer: $3\dfrac34\text{ miles per day}$

Step-by-step explanation:

We know that the formula to find speed is given by :-

$\text{speed}=\dfrac{\text{distance}}{\text{time}}$

Given: Distance = $\dfrac34$ mile

Time = $\dfrac15$ hour

Speed = $\dfrac{\dfrac34}{\dfrac15}\text{ miles per hour}$

$=\dfrac{3}{4}\times5\text{ miles per hour}\\\\=\dfrac{15}{4}\text{ miles per hour}\\\\=3\dfrac34\text{ miles per day}$

hence, speed = $3\dfrac34\text{ miles per day}$

What is the solution to the system of equations?

elixir [45]

Answer:

No solution

Step-by-step explanation:

$-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9\\\\$

Lets consider the equation 2.

Here we multiply the LHS and RHS with (-1).

$-3x-4y-3z=-7\\-(2x-6y+2z)=-3\\5x-2y+5z=9\\\\$

Hence,

$-3x-4y-3z=-7\\-2x+6y-2z=-3\\5x-2y+5z=9\\\\$

When we add the equations we get,

$0x+0y+0z=-10+9\\Hence,\\0=-1$

As 0 doesn't equal to -1, answer is d) No solution

Five less than twice the square of a negative number is -9 times the number. Find the number.

Rashid [163]

Since the first part says the value is five less then twice the square of a negative number we get the first equation as 2(-x)²-5. Then we have that -9x is equal to that previous equation. Therefore our new equation is 2(-x)²-5=-9x. We can move the nine over by adding it to both side to get 2(-x)²+9x-5=0. Then you can use any method of factoring (I prefer quadratic formula) to get your values for x. By doing so, you’ll get x=28 and x=-32.5. Since the problem said the number was negative in the first part, you know you can’t have the 28 as the answer so the right answer is -32.5.
