False
Because if you plot a graph to both the equation as i have attached the image.. you can see there can be multiple solution to the above system of inequalities.

False.
there are solutions to this system of inequalities.
-> For a quick check you can take random x, e.g. consider x=0, and substitute it   in the inequality, which gives
  y<5 and y>4 .
  there are infinite number of y satisfying these conditions.
-> You can solve it graphically to get exact solution. draw the line y=3x+5 and y = -x+4. The common region, below y=3x+5 and above y=-x+4 , is the solution for the system of inequalities.

The figure shows a pair of parallel line segmants on a coordinant grid. the line segments are translated 2 units to the left to

Nitella [24]

It is D because the segments don’t intersect and are just moving 2 units to the left. They are the same distance apart.

Hope it helps and is correct :)

Answer:

E(n)=$75000 *2^n

Step-by-step explanation:

If we start with the initial value, $75,000 , and keep multiplying by 2 , this function gives us Mapiya's cumulative earnings when she has written n sequels.

E(n)=75000⋅2

A tree cast a 25-foot shadow. At the same time of the day, a 6-foot man standing near the tree casts 9-foot shadow. What is the

Neporo4naja [7]

Answer:

The height of the tree is 16.67 feet.

Step-by-step explanation:

Refering the figure, let the height be "x" feet.

It is evident that triangles ABC and triangle EDC are similar.

(as both man and tree are perpendicular to the ground)

thus, $\frac{AB}{DE} = \frac{BC}{DC} = \frac{AC}{EC}$

hence,

$\frac{x}{6} = \frac{25}{9}$

Thus, $x = (\frac{25}{9})(6) = \frac{50}{3} = 16.67 foot.$ .

Sales tax in the state of Florida is 7%. Bob purchased a coat that was marked $350.00. What is the total bill including tax?

pav-90 [236]

To find the tax, you multiply the tax rate by the amount to be taxed, so...350 × 7%
350 × .07 = $24.50

This is the amount of tax. Now add it to the original price for the total cost.

$350.00 + $24.50 =

$374.50
