Write an equation of the line that passes through (-3,3) and is perpendicular to the line 2y=8x-6

jok3333 [9.3K]

Answer:

y = (-1/4)x + 9/4

Step-by-step explanation:

2y = 8x - 6

So, y = 4x - 3 (Slope = 4)

Slope of perpendicular line = -1/4

Equation of line: y-3 = (-1/4)(x-(-3))

y-3 = (-1/4)x - 3/4

y = (-1/4)x + 9/4

The blue lake trail is 11 3/8 miles long. Gemma has hiked 2 1/3 miles each hour for 3 hours. How far is she from the end of the

sergeinik [125]

Answer:

$4\frac{3}{8}miles$

Step-by-step explanation:

Given that Gemma has hiked 2 1/3 mile each hour for a total of 3 hours, you can multiply her rate by her time to find the total distance:

d = rt or d = 2 1/3(3)

$2\frac{1}{3}=\frac{7}{3}$

Multiply: $\frac{7}{3}*\frac{3}{1}=7miles$

Now, that the total length of the trail, 11 3/8 miles, and subtract the distance that Gemma has gone already:

11 3/8 - 7 = $4\frac{3}{8}miles$

Answer:

Mode

Step-by-step explanation:

Mean:

Before replacing = 464/8 = 58

After replacing 42 with 98 = 520/8 = 65

Mode:

Before replacing = 42

After replacing 42 with 98 = 98

Median:

25, 42 , 42 , 47, 55 , 59, 96,98

Before replacing = 47+55/2 = 51

25, 42 , 47, 55 , 59, 96,98 , 98

After replacing 42 with 98 = 55+59/2 = 114/2 = 57
