Step-by-step explanation:

F( x ) = 5 (3) ^ x

Y intercept

Let x = 0

f(0) = 5× 3 ^ 0

f(0 = 5 × 1

f(0) = 5

X intercept

let y = o

0 = 5 × 3 ^x

No x intercept/ zero

therefore

Vertical intercept (0; 5)

Answer:

$3y^{2}+2y-11$

Step-by-step explanation:

we have

$(-y^{2}-4y-8)-(-4y^{2}-6y+3)$

Eliminate the parenthesis

$-y^{2}-4y-8+4y^{2}+6y-3$

Group terms that contain the same variable

$-y^{2}+4y^{2}-4y+6y-8-3$

Combine like terms

$3y^{2}+2y-11$

A single die is rolled twice. The 36 equally-likely outcomes are shown to the right. Find the probability of getting first an o

dangina [55]

36 equally-likely outcome: (1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1),(6,2), (6,3), (6,4), (6,5), (6,6)

Solution:
Outcomes with first number being old number and second being even number: (1,2), (1,4), (1,6), (3,2), (3,4), (3,6), (5,2), (5,4), (5,6) = 9 outcomes

P(old,even) = 9/36 =1/4 = 0.25

Leno4ka [110]

Answer:

Step-by-step explanation:

2x - 2y = 2

5x + 2y = 12

7x = 14

(2x - 2y = 2)-5

(5x + 2y = 12)2

-10x + 10y = -10

10x + 4y = 24

14y = 14

x = 2

y = 1
