4. What is the equation of line passing through (-2,4) and parallel to the line y<br> + 3x = 4?
aliya0001 [1]

Answer:

y=-3x-2

Step-by-step explanation:

step 1- find the slope

parallel to means same slope, so look at y+3x=4, its not in the correct slope form so we subtract both sides by 3x to get y=-3x+4, the slope is the coefficient of x which is -3. Slope equals 3

step 2- use the point slope form which is y-y1=m(x-x1)

and substitute in the numbers (only substitute y1,x1, and m)

m is the slope which we found to equal -3

x1 and y1 are the points that they gave us (-2,4) are (x1,y1)

x1=-2

y1=4

step 3- substitute

y-y1=m(x-x1)

y-4=-3(x-(-2))

simplifies to y-4=-3x-6

add 4 to both sides to get y=-3x-2

Answer:

<u>The correct answer is 5/24 or 0.21</u>

Step-by-step explanation:

1. Let's review all the information given to answer the question correctly:

Science class in seventh grade = 4 girls and 4 boys

Science class in eighth grade = 5 girls and 7 boys

2. What is the probability that both students selected for the competition are girls,  a seventh grader and an eighth grader?

These are independent events, therefore:

Probability of two independent events = Probability of A * Probability of B

Probability of both students selected for the competition are girls = 4/8 * 5/12

Probability of both students selected for the competition are girls = 20/96 = 5/24

<u>The correct answer is 5/24 or 0.21</u>
