3y+15=5y-1
1. Subtract 5y from each side, so you are left with -2y+15=-1
2.Subtract 15 from each side, so you are left with -2y=-16

Serhud [2]

Answer:

i believe the answer would be y= -x-4

Step-by-step explanation:

a line that is perpendicular, will have and opposite reciprocal slope, so:

the slope of the line y=x-4 is 1, and the reciprocal of 1 is also 1.

now take the opposite of it, which is -1.

so the perpendicular line equation would be y=-x-4

i hope this helps :D

The angle of elevation of the sun is 24°. What is the length of the shadow cast by a person 1.82 m tall?
amm1812

Answer:

4.09 m

Step-by-step explanation:

Let the length of the shadow cast by a person be x m.

\tan \: 24 \degree =  \frac{height \: of \: person}{length \: of \: the \: shadow}  \\  \\ 0.4452286853 =  \frac{1.82}{x}  \\  \\ x =  \frac{1.82}{0.4452286853}  \\  \\ x = 4.08778693 \: m \\ x = 4.09 \: m

Which number line represents the solution set for the inequality <br> 3(8-4x) &lt; 6(x-5) ?
viktelen [127]

Answer:

Second number line(from top to bottom).

Step-by-step explanation:

We are given the following inequality:

3(8 - 4x) < 6(x - 5)

It is solved similarly to an equality, so:

24 - 12x < 6x - 30

-18x < -54

Multiplying by -1, the signal changes from < to >. So

18x > 54

x > \frac{54}{18}

x > 3

Thus the correct answer is given by the second number line.
