Solve this by substitution

Mathematics
1 answer:
frozen [14]3 years ago
6 0

Answer:

y= 1 and x=-2

Step-by-step explanation:

Since they both equal y, you can equal them to each other:

x + 3 = 2x + 5

Then solve:

x - x + 3 = 2x - x + 5

3 - 5 = x + 5 - 5

-2 = x

Substitute x in either equation to solve for y:

y = (-2) +3

y = 1

Or the other equation:

y = 2(-2) + 5

y = -4 + 5

y = 1

hope this helps :)

A car travels around a circular track of radius 1.5 miles. It traversed35of a complete revolution. Howfar did it travel?
Arturiano [62]

Answer:

The total distance traveled by the car is 330 miles.

Step-by-step explanation:

The circular track is the circumference of circle with radius 1.5 miles.

Circumference of a circle = 2\pir

Thus,

Circumference of the track  = 2 x \frac{22}{7} x 1.5

                           = 9.4286571429

Circumference of the track = 9.4286571429 miles

But, one complete revolution by the car is the circumference of the track.

i.e One complete revolution round the track = 9.4286571429 miles

Therefore,

35 complete revolutions round the track = 35 x 9.4286571429 miles

                                       = 330 miles

The total distance traveled by the car is 330 miles.

Which statement correctly explains whether or not the values in the table represent a function of x
Lemur [1.5K]

Answer:

Step-by-step explanation:

A relation is said to be a function when each input value (x-value) show a distinct output value (y-value).

From the table attached,

For input value x = 0, there are multiple values of output values (y = -2, -1, 0, 1, -2).

Therefore, data given in the table doesn't represent a function.
