Answer:

y=-\frac{5}{2}x-24

Step-by-step explanation:

2x-5y=-12\\5y=2x+12\\y=\frac{2}{5}x+\frac{12}{5}\\

if two lines perpendicular,

m_{1} .m_{2}=-1\\ \frac{2}{5} .m_{2}=-1\\m_{2}=-\frac{5}{2}

the line perpendicular to this line is

y=-\frac{5}{2}x+k ; k ∈ R

the line passes through the point (10,-1)

so,

-1=-\frac{5}{2} (10)+k\\-1=-25+k\\k=-24

∴the equation of the line perpendicular to 2x-5y=-12 that passes through the point (10,-1) is

y=-\frac{5}{2}x-24

Find the domain and the range of the relation. Determine whether the relation is a function.
andre [41]

Answer:

Domain: {-6, -1, 7}

Range: {-9, 0, 9}

The relation is not a function.

Step-by-step explanation:

Given the relation: t{(−1,0),(7,0),(−1,9),(−6,−9)}

In the ordered pairs:

  • The domain is the set of all "x" values
  • The range is set of all "y" values
  • We do not need to list any repeated value in the range/domain more than once.

Domain: {-6, -1, 7}

Range: {-9, 0, 9}

Next, we determine whether the relation is a function.

For a relation to be a function, each x must correspond with only one y value.

However, as is observed in the mapping attached below:

  • f(-1)=0
  • f(-1)=9

The x-value (-1) corresponds to two y-values (0 and 9)

Therefore, the relation is not a function.

This is with radicals
Lynna [10]

Answer: -16

Step-by-step explanation:

2(x+4)

———— = 8

- 5

2x+8

——— = 8

-5

2x+8

-5 • ——— = 8(-5)

-5

2x+8 = -40

2x = -32

x = -16
