HELPPPP <br>y=1/8x+3 in standard form

lidiya [134]

Answer:

$x-8y=-24$

Step-by-step explanation:

Standard form of a linear equation: $Ax+By=C$

(where A, B and C are integers, and A shouldn't be negative)

Given equation:

$y=\dfrac{1}{8}x+3$

Multiply both sides by 8:

$\implies 8 \cdot y=8 \cdot \dfrac{1}{8}x+8 \cdot 3$

$\implies 8y=x+24$

Subtract 8y from both sides:

$\implies 8y-8y=x+24-8y$

$\implies 0=x+24-8y$

Subtract 24 from both sides:

$\implies 0-24=x+24-8y-24$

$\implies -24=x-8y$

In standard form:

$\implies x-8y=-24$

A board game has 25 cards, each printed with a number from 1 through 25. Sameer shuffled the cards, and then selected 1 card.

Inessa05 [86]

We have to find the probability that one randomly selected card has a number less than 4 or a multiple of 9. There are numbers : 1 - 25. Numbers less than 4 are: 1, 2, and 3. Multiples of 9 that are less than 25 are : 9 ( 9 * 1 ) and 18 ( 9 * 2 ). So there are 5 favourable outcomes and 25 possible outcomes. The probability is: P ( A ) = ( number of favourable outcomes ) / ( number of possible outcomes ) = 5 / 25 = 1 / 5 = 0.2. Answer: The probability is 0.2 or 20 %<span>. </span>
