Please solve these 2 ;-;<br><br> y = 2x – 6<br> y = –4x + 3
Yuri [45]

Answer:

x = 3/2 | y = -3

Step-by-step explanation:

Given equations:

  • y = 2x - 6. . . .(i)
  • y = -4x + 3. . . . (ii)

Substituting from equation (i) for y:

==> 2x - 6 = -4x + 3

==> 2x + 4x = 6 + 3

==> 6x = 9

<em>dividing both </em><em>sides by 3</em><em>:</em>

==> 2x = 3

==> x = 3/2

Substituting 3/2 for x in equation (i):

==> y = 2(3/2) - 6

==> y = 3 - 6

==> y = -3

A student ran out of time on a multiple choice exam and randomly guessed the answers for two problems. Each problem had 5 answer
choli [55]

Answer:

there is a 64% chance that the student got both problems wrong

a 32% chance that they got only 1 correct

and a 4% chance that they got both correct

There are 25 total possible combinations of answers, with 8 possible combinations where the student would get 1 answer right, and 1 combination where the student would get both answers correct.

25-9=16

\frac{16}{25} =\frac{x}{100}

\frac{64}{100}

64%

\frac{8}{25} =\frac{y}{100}

\frac{32}{100}

32%

\frac{1}{25} =\frac{z}{100}

\frac{4}{100}

4%
