Find the sum of (x + 5) and (2x + 3)

1 answer:

7 0

What you can do is subtract 1x from each side
Then you subtract 3 from each side
Then it tells you x=2
Always put what you think x is back into the problem and see if it works out

Example on how you do it:
(x+5)=(2x+3)
5=(x+3)
2=x

What is the equation of an exponential function with base=2 that has a vertical stretch by a factor of 3, a shift to the right 5

il63 [147K]

Answer:

$y=3(2)^{x-5}+6$

Step-by-step explanation:

Let the equation of the exponential function with base 2 is,

$y=a(2)^{x+c}+d$

Here, a = vertical stretch

c = Horizontal shift

d = Vertical shift

If this function has a vertical stretch by a factor of 3,

Equation will be,

$y=3(2)^{x+c}+d$

If this function has a shift of 5 to the right,

Equation of the function will be,

$y=3(2)^{x-5}+d$

If this function has a shift of 6 units upwards,

$y=3(2)^{x-5}+6$

Area of paralellogram with base 15cm and height12cm

azamat

Answer:

180 cm2

Area of a polyhedron:

15(=base)x12(=height)

=180cm2

btw parallelogram is a 2D pic how you can come out a ''base'' and ''height''? It should be called a polyhedron. Your question is weird.

If so, your ''area of parallelogram'' is 15cm2 since your question is hecking weird.

Btw it's 15cm2 not 15

Please check ur question b4 u ask
