By evaluating the linear equation, we can complete the table:

x: -2 | -1 | 0 | 1 | 2 |

y: -3 | -1 |  1 | 3 | 5  |

<h3>How to complete the given table?</h3>

Here we want to complete the table:

x: -2 | -1 | 0 | 1 | 2 |

y:     |    |    |    |    |

To get the correspondent values in the "y" row, you just need to evaluate the linear function in the given values of x.

Here the function is:

f(x) = 2x - 1

Evaluating it we get:

f(-2) = 2*(-2) + 1 = -3

f(-1) = 2*(-1) + 1 = -1

f(0) = 2*0 + 1 = 1

f(1) = 2*1 + 1 = 3

f(2) = 2*2 + 1 = 5

Now we just put these values in their correspondent place on the table.

x: -2 | -1 | 0 | 1 | 2 |

y: -3 | -1 |  1 | 3 | 5  |

A park is 4.6 miles long and 2.7 miles wide. A:what is the total distance around the park? B:if a racecar drove 50 times around
Vlada [557]

Answer:

A) Total distance around the park is 14.6 miles

B) The total distance drove by racer 730 miles

Step-by-step explanation:

Given as :

The length of park = 4.6 miles

The width of park = 2.7 miles

Let the total distance cover around park = Perimeter of park = P miles

So, Perimeter of rectangular park = 2 × Length + 2 × width

or, P = 2 × 4.6 + 2 × 2.7

I.e P = 9.2 + 5.4

Or, perimeter = 14.6 miles

A ) ∴ Total distance around the park = 14.6 miles

B ) The total distance drove by racer = 50 times around the park

  So, The total distance drove by car = 50 × Total distance around the park

∴The total distance drove by car = 50 × 14.6 = 730 miles

Hence A) Total distance around the park is 14.6 miles

          B) The total distance drove by racer 730 miles   answer

Given that 7 x − 2 y = 35 Find y when x = − 9
Sergio [31]

so x = minus 9

then

7 × (-9) - 2y = 35

-63 - 2y = 35

-2y = 35 plus 63

-2y = 98

- y = 49

y = -49

BabaBlast [244]

Answer:

Both are correct!

Step-by-step explanation:

if R = 26 - 17 = 9

now the next one

17 + R = 26

Same thing as R = 26 - 17 = 9
