Answer:

  • (2, -2)

Step-by-step explanation:

<u>Given</u>

  • y = x - 4
  • 2x + y = 2

<u>Solving by substitution</u>

  • 2x + (x - 4) = 2
  • 3x - 4 = 2
  • 3x = 6
  • x = 2

<u>Then finding y</u>

  • y = x - 4
  • y = 2 - 4
  • y = -2

Intersection point is (2, -2)

PLEASE SOLVE DUE RIGHT NOW!!!!!!!!!!!!
erma4kov [3.2K]

Solution:

<u>We know that:</u>

Area \ of \ triangle = \dfrac{1}{2} \times Base \times Height

<em>Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.</em>

Area \ of \ triangle = \dfrac{1}{2} \times 18 \times24

<u>Cancel out the "2" by dividing it by 18.</u>

Area \ of \ triangle =  9 \times24

<u>Simplify the multiplication.</u>

\bold{Area \ of \ triangle =  216 \ ft^{2}}

assume a telephone signal travels through a cable at two-thirds the speed of light. how long does it take the signal to get from
Helen [10]

The time length for a sign to travel from new york to Miami is 0.089 seconds.

We understand the speed of mild in miles per 2nd is 186,000.

the rate of smartphone signal is 2/3rd is =2/3rd of 186,000

                                                                     = 124,000 miles in line with 2nd

Distance among Miami and new york is given to be 1100 miles.

So, the time required to journey the phone signal from new york city to Miami is = distance ÷ speed

              = 1100 ÷ 124,000

              =0.089 seconds

Time taken via the telephone sign from Miami to new york is 0.089 seconds.
