27)
2x^2 - 5x = -2
2x^2 - 5x +2 = 0
(2x - 1)(x -2) = 0
2x - 1; x = 1/2
x - 2 = 0; x = 2

x = 1/2 or x =2

answer is B
x = 1/2 or x =2

Find X when x equals negative 15

Ann [662]

Judging by the question you have provided I came to the conclusion that you have already solved your own problem!

If the goal is to find X when X=-15 then your answer for X should be -15!

If this is not the entire equation please post the entire one!

Hope this helped!

• Packaging of a product can cost a lot of money. Can you design

podryga [215]

The best arrangement can be

3 rows and 4balls each row

So

Length of one row=1.8(4)=7.2cm
Width=1.8(3)=5.4cm
Height=1.8(2)=3.6cm

So

TSA

2(LB+BH+LH)
2(5.4(7.2)+(7.2)(3.6)+3.6(5.4))
2(84.24)
168.48cm²

Total cost

168.48(0.01)
1.685€

Amy wants to sell at most 25 cookies and at least 10 sprites

Inga [223]

Answer:

$x\leq 25\\y\geq 10\\.50x + y\geq 30$

Step-by-step explanation:

It is given that,

Amy wants to sell at most 25 cookies ,

Let number of cookies be ' $x$ ' , then $x$ should be less than or equal to 25

Which is represented by $x\leq 25$ ,

Further,

Let number of sprites be ' $y$ ', then ' $y$ ' should be greater than or equal to 10

Which is represented by $y\geq 10$

Also,

Given,

she profits $.50 on every cookie

and $1.00 on every sprite.

So total profit on selling cookies would be

= Profit on each cookie times the number of cookies

= $.50\times x$

= $.5x$

Similarly, total profit on selling sprites would be

=profit on each sprite times the number of sprites

= $1.00\times y$

= $y$

Now, combining these two should be greater than or equal to $30

representing this through an equation,

$.50x+y\geq 30$

Thus the sysytem of equations is given as:

$x\leq 25\\y\geq 10\\.50x + y\geq 30$
