Answer:
$700
Step-by-step explanation:
Step one:
Given data
Regular cost of cell phone= $780
discount = 15%
tax = 5.5%
Step two
Let us compute the discounted amount
= 15/100*780
=0.15*780
=$117
hence the selling price is
=780-117
=$663
Also, the tax-deductible is
=5.5/100*663
=0.055*663
=$36.465
The total cost of the phone will be
=663+36.465
=699.465
=$700 to the nearest cent
Slope intercept form is y=mx+b. since there is no b term, the y intercept is 0. since there is a 9 in the m term, your slope will be nine. based on those two things, you need a point at (0,0) and (1,9). on the other end, your point will be (-1,-9). then draw a straight line through. hope this helps :)

Step-by-step explanation:
Answer:
In general, we already know how to solve problems in a right triangle using the concept of trigonometry. Meanwhile, as we also know that the type of triangle is not only a right triangle, but there are isosceles, equilateral, or even random triangles. The question is how to solve the problems that exist in these triangles It is known that there is an arbitrary triangle with sides a, b, and c. The angle formed in front of side a is called angle α, the angle formed in front of side b is called angle β, and the angle formed in front of side c is called angle γ = 5
Step-by-step explanation:
x" + 5x + 6 = 0
(x + 2)(x + 3) = 0
x + 2 = 0
x = -2
x + 3 = 0
x = -3

Answer:
1). y= -5+3x
2). y= -2x-13
3). y= -6x+2
4). y= -x+4
5). y≈ 0.57x
6). y=2x-9
7). Equation incomplete
8). y=3x+23
Step-by-step explanation:
1).
3x-y=5
<em>Subtract 3x from both sides</em>
-y=5-3x
<em>Multiply both sides by -1</em>
y= -5+3x
2).
y+7= -2(x+3)
y+7= -2x-6
<em>Subtract 7 from both sides</em>
y= -2x-13
3).
y= -10-6(x-2)
y= -10-6x+12
y= -6x+2
4).
3x=12-3y
<em>Add 3y to both sides</em>
3x+3y=12
<em>Subtract 3x from both sides</em>
3y=12-3x
<em>Divide both sides by 3</em>
y= -x+4
5).
-4x-7y=0
<em>Add 4x to both sides</em>
-7y= -4x+0
<em>Multiply both sides by -1</em>
7y= 4x
<em>Divide both sides by 7</em>
y≈ 0.57x
6).
4x-2y=18
<em>Subtract 4x from both sides</em>
-2y= -4x+18
<em>Multiply both sides by -1</em>
2y=4x-18
<em>Divide both sides by 2</em>
y=2x-9
7).
y= 5-
Equation is incomplete.
8).
y-2=3(x+7)
y-2=3x+21
<em>Add 2 to both sides</em>
y=3x+23
