a car covers a distance of 490 km with a speed of 70km and then covers a speed of 90km calculate its average speed

Average speed = total distance divided by total time.

In the first part, the car covered 490 km in 7 hours, but I think you mistyped the second part (“then covers a speed of 90km”) and a critical piece is missing to find the total distance and time.

For this case we have that by definition, a linear equation is of the form:

$ax + b = 0$

The variable (s) involved in the equation always have exponent 1.

Some examples of linear equations are:

$x + 5 = 3y\\y + 6 = 3x\\y = 2x + 2$

Answer:

In a linear equation the variables have exponent 1.

$y = 2x + 2$

Find the equation of the line:

natta225 [31]

Answer:

x=4.5.

The slope is undefined. Thus the y variable is irrelevant. It appears as though the line crosses through 4.5 on the x axis making the equation

x = 4.5

Answer:

Step-by-step explanation:

Lines l and m are the parallel lines and 't' is a transversal line,

Therefore, ∠1 ≅ ∠5 [Corresponding angle postulate]

∠5 ≅ ∠7 [Vertical angles theorem]

∠1 ≅ ∠7 [Transitive property]

Therefore, ∠1 ≅ ∠7 [Alternate exterior angles theorem]
