G. $y = \frac{1}{2} x + 1$

Step-by-step explanation:

$\because \: line \: m \: is \: passing \: through \: the \: \\ points \: (3, \: 2) \: and \: (4, \: 0) \\ \\ slope \: of \: line \: m = \frac{0 - 2}{4 - 3} = \frac{ - 2}{1} = - 2 \\ \\ \because \: line \: l \perp \: line \: m \\ \\ \therefore \: slope \: of \: line \: l = - \frac{ 1}{slope \: of \: line \: m} \\ \\ \therefore \: slope \: of \: line \: l = \frac{1}{2} \\ \\ line \: l \: is \: passing \: through \: (6, \: 4) \\ \\ \therefore \:equation \: of \: line \: l \: in \: point \: slope \: \\ form \: is \: given \: as \\ \\ y - 4 = \frac{1}{2} (x - 6) \\ \\ y - 4= \frac{1}{2} x - 3 \\ \\ y = \frac{1}{2} x - 3 + 4 \\ \\ \huge \red{ \boxed{y = \frac{1}{2} x + 1}}$

One number is 5 more than the other. Their sum is 33. Find the numbers.

dimaraw [331]

Answer:

19,14

Step-by-step explanation:

x=5+y

x+ y= 33

we will solve using substitution

(5+y) +y= 33

5+y+y=33

5+2y=33

subtract 5 from both sides

2y=28

y=14

We got y now we will find what x is

for this, we will substitute y's value (14) into the first equation

x=5+(14)

x=19

we got x too
