Please help me with thisss

Answer:

(x, y) = (-2, -3)

WORK:

2x + 4y = -16 =

-2x + 2y = -2 =

(^ the two’s cancel out) =

6y = -18 =

(^ you need to divide 6 on both sides to get just y) =

6y/6 = -18/6 =

(^ the six’s cancel out) =

y = -3 =

(^ now you have to plug this in to get x) =

2x + 4(-3) = -16 =

2x - 12 = -16 =

(^ you need to add 12 on both sides to get rid of it on the left side to add it to -16 on the right side) =

2x = -4 =

2x/2 = -4/2 =

(^ now you divide 2 on both sides again to get just y, and they will cancel out) =

x = -2 =

THEREFORE YOU GET (-2, -3)

A certain university has 18 vehicles available for use by faculty and staff. Five of these are vans and 13 are cars. On a partic

Reil [10]

Answer:

$P(E) = 0.278$

$P(F |E) = 0.2353$

$P(E and F) = 0.0654$

Step-by-step explanation:

The number of vehicles available is $N = 18$

The number of vans is k = 5

The number of cars is n = 13

Generally P(E) is mathematically represented as

$P(E) = \frac{k}{N}$

=> $P(E) = \frac{5}{18}$

=> $P(E) = 0.278$

Generally P(F| E) means the probability that the second vehicle assigned is a van given that the first one selected is a van this mathematically calculated as

$P(F |E) = \frac{5 -1}{18-1}$

$P(F |E) = \frac{4}{17}$

$P(F |E) = 0.2353$

Generally $P(F | E)$ is also mathematically represented as

$P(F | E) = \frac{P(E and F)}{P(E)}$

=> $P(E and F) =P(E) * P(F | E)$

=> $P(E and F) = 0.278 * 0.2353$

=> $P(E and F) = 0.0654$

Help plz consider the sequence {4,6,8,10...}Find the explicit formula that defines the sequence. A) an = 2n + 2 B) an = 2n + 4 C

Alex777 [14]

this is an arithmetic sequence whose n th term ( explicit formula) is

$a_{n}$ = $a_{1}$ + (n - 1 )d

where d is the common difference and $a_{1}$ the first term

here d = 10 - 8 = 8 - 6 = 6 - 4 = 2 and $a_{1}$ = 4, hence

$a_{n}$ = 4 + 2(n - 1 ) = 4 + 2n - 2 = 2n + 2 → A
