At a baseball game, Carlton buys 2 hotdogs and 1 box of popcorn for $6.75. Manny buys 1 hotdog and 1 box of popcorn for $4.25. h

Ne4ueva [31]

Answer:

1 Hot dog = $2.50; 1 Nacho = $3.00

Step-by-step explanation:

Let x be the cost of 1 hotdog

let y be the cost of 1 nacho

6 x + 3 y = 24 (Equation 1)

8 x + 1 y = 23 (Equation 2)

Divide equation 1 by 3

2 x + y = 8 (Equation 3)

Subtract Equation 3 from Equation 2

8 x − 2 x +y − y = 23 − 8

Simplifying

6 x = 15

1 Hot dog = $2.50

Substitute the value calculated above into Equation 1

15 + 3 y = 24

3 y = 9

1 Nacho = $3.00

How does the graph of the function g(x)=2^x-4 differ from the graph of f(x)=2^x

VARVARA [1.3K]

Answer:

The graph of g(x) is the graph of f(x) moved down 4 units.

Step-by-step explanation:

Subtracting a function by a constant:

Subtracting a function by a constant x is the same as moving the function down x units.

In this question:

$f(x) = 2^x$

$g(x) = 2^x - 4$

Thus, the graph of g(x) is the graph of f(x) moved down 4 units.

How do you do... cos2x-sin2x=1-2sin2x

Bess [88]

$sin (2 \alpha) =2\cdot sin \alpha \cdot cos \alpha \\cos(2 \alpha )=1-2sin^2 \alpha \\-------------------- \\cos2x-sin2x=1-2sin2x\\cos2x+sin2x=1\\1-2sin^2x+2sinx\cdot cosx=1\\-2sinx(sin x-cosx)=0\\ -2sinx=0\ \ \ \ or\ \ \ \ sinx-cosx=0\\\\1)\ -2sinx=0\ \ \Leftrightarrow\ \ sinx=0\ \ \Leftrightarrow\ \ x_1=k \pi \ \ and\ \ k\in I\\2)\ \ sinx-cosx=0\ \ \Leftrightarrow\ \ sinx=cosx\ /:cosx\ \ \ \ \ \wedge\ \ \ \ cos x \neq 0\\tanx=1\ \ \Leftrightarrow\ \ x_2= \frac{ \pi }{4} +k \pi \ \ and\ \ k\in I$
