Don and Marie like to go to a good restaurant. Dinners are $16 to $19 dollars with soup or salad. A beverage is $1.50. Dessert i

s $3.75. If one dinner is $16, the other is $19 and each diner has a beverage and dessert, what will the cost be if a 6% tax is charged and a 15% tip on the pre-tax amount is left?

Hi there!

The correct answer is calculated like so:

16 + 19 + 3 + 3.75 + 3.75 = 45.5

45.5 * 0.06 = 2.73

45.5 * 0.15 = 6.83

45.5 + 2.73 + 6.83 = $55.06

Answer: $55.055

Step-by-step explanation:

The cost of one dinner = $16+$1.50+$3.75=21.25

The cost of the other dinner = $19+$1.50+$3.75=24.25

The total cost of both the dinners = 21.25+24.25=\$\ 45.5

The 15% tax on the cost of dinners = 0.15\times45.5=\$\ 6.825

The 6% tax on the dinners =0.06\times45.5=\$2.73

The total cost of the dinners =\$\ 45.5+\$\ 6.825+\$\ 2.73=\$55.055

The cost of dinners if a 6% tax is charged and a 15% tip on the pre-tax amount is left =$55.055

Remember, parenthaees are like < and > and brackets ar like ≤ and ≥

domain is how far the x values go
x is left to right

we see they go from -3 to 5, with a filled in dot at -3 and empty dot at 5
means include -3 but not including 5
so like -3≤x<5
or in interval notation
[-3,5) is the domain



range
highest to lowest y value

range is from y=3 to y=-1
we gots full dots so we use brackets
range is [-1,3]



Domain=[-3,5)
Range=[-1,3]

X^2+2x+1 is a perfect square trinomial <br><br> True of False?
Nimfa-mama [501]

Answer:

True.

Step-by-step explanation:

It is because it is in the form a^2x^2+2abx+b^2 and this equals (ax+b)^2.

Why it is in that form:  well comparing  a^2x^2+2abx+b^2, we have a=1, b=1. Testing, plug in those values:

(1)^2x^2+2(1)(1)x+(1)^2

1x^2+2x+1

x^2+2x+1.

This has the squared form of (x+1)^2.

Test if you like:

(x+1)^2

(x+1)(x+1)

Use foil to expand:

First: x(x)=x^2

Outer: x(1)=x

Inner: 1(x)=x

Last: 1(1)=1

---------------Add together

x^2+2x+1

It does indeed equal.
