Answer:

Step-by-step explanation:

30/7 = 4 2/7

Because 7 only goes into 30, four times (7 x 4 = 28) anything else would be too big.

7 goes into 30 four times, and you get left with a remainder of 2

So you write 4 wholes, then 2/7 because 2 is the remainder it goes on top, and 7 stays in the denominator (bottom)

Write the equation of the line which passes through (2, –1) and is perpendicular to the line with equation 5y – x = 1.

Furkat [3]

Solve 5y - x = 1 for y such that y = mx + b so we can extract the slope.
y = 1/5x + 1/5
Perpendicular lines have opposite signed reciprocal slopes.
1/5 would have an opposite signed (-) reciprocal (5) slope of -5

Now let's find b by substituting the values of y, m, and x into y = mx + b:
-1 = -5(2) + b
-1 = -10 + b
9 = b
So the equation is y = -5x + 9 or 5x + y = 9
