Answer:

t=11.9

Step-by-step explanation:

960=420(2)^t/10

2.28571429=2^t/10

add log to both sides

log(2.28571429)=10 t log(2)

divide by log 2

1.19264508= 10 /t

10(1.19264508)

11.926450779=t

IrinaVladis [17]

Answer:

Therefore,

$6r-r++(15-r)+23-6 = -3r+137$ i.e

$6r-r+8(15-r)+23-6$ and

$-3r+137$ are Equivalent .

Step-by-step explanation:

To Check:

$6r-r+8(15-r)+23-6$ and

$-3r+137$ is Equivalent or Not

Solution:

Consider,

$6r-r+8(15-r)+23-6$

Step 1 . Apply Distributive Property , A(B+C)=AB+AC we get

$6r-r+8\times 15-8\times r+23-6$

$6r-r+120-8r+23-6$

Step 2 . Combining Like Terms i.e r terms and the numbers we get

$6r-r-8r+120+23-6$

$-3r+137$

Which is Equivalent to the given expression

$-3r+137$

Therefore,

$6r-r+8(15-r)+23-6= -3r+137$ i.e

$6r-r+8(15-r)+23-6$ and

$-3r+137$ ..........are Equivalent .

marusya05 [52]

Answer:

d. g(x) = -7x - 4

Step-by-step explanation:

If it is reflected over the x-axis, there is a negative sign to the x term.

There is a shift of 4 units, so it is -4.
