At Home Depot, Johnny bought 3 rose bushes and 7 flats of petunias for a total of
vitfil [10]

Answer:

Step-by-step explanation:

At Home Depot, Johnny bought 3 rose bushes and 7 flats of petunias for a total of  $114.75.

Let x = rose bushes

Let y = petunias

This means;

3x + 7y = 114.75 ..... (i)

Rosie bought 2 rose bushes and 6 flats of petunias for a total of $89.50.

2x + 6y = 89.50 ..... (ii)

How  much does a rose bush cost? How much does a flat of petunias cost?

Multiply eqn (i) by 2 and eqn (ii) by 3.

This results too;

6x + 14y = 229.5 .... (iii)

6x + 18y = 268.5 .....(iv)

Subtract eqn (iii) from eqn (iv)

This results to;

4y = 39

y = 39 / 4 = $9.75

Subt the vale of y in eqn ii

2x = 89.50 - 6y

x = (89.50 - 6y) / 2

x = (89.50 - 6(39 / 4)) / 2

x = 31 / 2 = $15.5

The length of a rectangle is 18 centimeters less than five times its width. its area is 35 square centimeters. find the dimensio
Studentka2010 [4]
35 = 5*7
7 = 5*5 -18

The dimensions of the rectangle are: length = 7 cm, width = 5 cm.

_____
It is handy to know your times tables.

___
If you want, you can write a couple of equations and solve them.
.. L = 5W -18
.. LW = 35
Substituting for L, we have
.. (5W -18)W = 35
.. 5W^2 -18W -35 = 0 . . . . put in standard form
.. (W -5)*(5W +7) = 0 . . . . . factor
.. W = 5 or -7/5 . . . . . . . . . we are only interested in the positive solution

The width of the rectangle is 5 cm; its length is 7 cm.

The graph of the function is of the form<br> f(x) = a * sin(kc – c) + h.
Brut [27]
The answer is : f(x) =3sin(2x+pi/2)

Explain

There 0,3 on the graph

You use this formula

f(x)=asin(kx-c)+h

and the maximum and minimum value of this function

a+ h and -a+ h

So a=3 and h=0

So we have

We have; f(x)= 3sin(kx - c)
and we have from the graph;

f(O)=3

So

Sin(-c) =-1

Therefore C=. Pi/ 2 +2pi n

We have period of the function is pi


2pi/ k
k=2
So it will equal Pi


Do you have any doubts ?
