Answer:

y = x - 4

Step-by-step explanation:

The line passes through (-1,-5) and (-3,-7)

The slope of a line is given by; change in y ÷ change in x

i.e slope = \frac{-7 - -5}{-3 - -1} = \frac{-2}{-2} = 1

Taking another point (x,y) on the line.

Slope will be; \frac{y - -5}{x - -1} = 1

Cross multiplying gives; y + 5 = x + 1

Simplifying this equation gives us the equation of our line which is;

y = x - 4

Mekhanik [1.2K]

Given:

The function is:

f(x)=x^2-x+1

To find:

The result of the operation -f(x)=-(x^2-x+1).

Solution:

If g(x)=-f(x), then the graph of f(x) is reflected across the x-axis to get the graph of g(x).

We have,

f(x)=x^2-x+1

The given operation is:

-f(x)=-(x^2-x+1)

So, it will result in a reflection across the x-axis.

Therefore, the correct option is A.

The space shuttle can travel at 28968 km/h what distance can it cover in 8 hrs?
Verdich [7]

Given:

A space shuttle can travel at 28968 km/h.

To find:

The distance it can cover in 8 hrs.

Solution:

We have,

Speed of space shuttle = 28968 km/h.

So,

Distance covered by the space shuttle in 1 hour = 28968 km/h.

Distance covered by the space shuttle in 8 hour = (28968 × 8) km

                                                                                 = 231744 km

Therefore, the distance it can cover in 8 hrs is 231744 km.
