Answer:
The second deal offers a lower cost for the three friends.
Step-by-step explanation:
Let consider that each pizza has a price [tex]c_{o}[/tex]. Now, we proceed to check the total cost for each case, the better choice is whose total cost after discounts is the lowest.
Case 1 - 10 % off of 1 pizza (Split costs and buy 3 pizzas separately)
[tex]C = 0.9\cdot C_{o} + 0.9\cdot C_{o} + 0.9\cdot C_{o}[/tex]
[tex]C = 2.7\cdot C_{o}[/tex]
The cost for each person is:
[tex]c = \frac{C}{3}[/tex]
[tex]c = 0.9\cdot C_{o}[/tex]
Case 2 - 30 % off of 3 pizzas (Split costs and buy 3 pizzas in a row)
[tex]C = 0.7\cdot (3\cdot C_{o})[/tex]
[tex]C_{o} = 2.1\cdot C_{o}[/tex]
The cost for each person is:
[tex]c = \frac{C}{3}[/tex]
[tex]c = 0.7\cdot C_{o}[/tex]
The second deal offers a lower cost for the three friends.
the graph of the function y=x^(2) is reflected across the x-axis, then translated two units left and six units down, write and equation to represent the new functoin
Answer: -4,-2
Step-by-step explanation: Since it is reflected across the x- axis, translated two units left and six units down it would be -4, -2 because 2-6= -4

Jina made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $33.60. If the beads cost a
total of $14.40, how much did each pendant cost?
Answer:
$3.215
Step-by-step explanation:
Total cost of the beads and pendants = $33.60
Total number of necklaces = 6
Cost of beads = $14.40
To find : cost of each pendant.
Total cost of pendants = $33.69 - $14.40
= $19.29
Now, cost of each pendant = $19.29/6
= $3.215

help me with this math question please I'm giving away brainliests
Answer:
Step-by-step explanation:
Given function in the question is,
[tex]f(x)=\frac{-2x^2-4x}{4x+8}[/tex]
[tex]=\frac{-2x(x+2)}{4(x+2)}[/tex]
[tex]=-\frac{1}{2}x[/tex] If [tex]x\neq -2[/tex]
Given function is not defined at x = -2
At x = -2,
[tex]f(-2)=\frac{1}{2}(2)[/tex]
[tex]=1[/tex]
Therefore, there is a hole in the graph at (-2, 1).
Graph of the function 'f' will be a straight line with a hole at (-2, 1).
Horizontal asymptote → None
Vertical asymptote → None
x-intercept → No x-intercept [Line passes through origin (0,0)]
y-intercept → No y-intercept [Line passes through origin (0,0)]
Hole → (-2, 1)

Which is a finite geometric sequence?
a. {300, 30, 0.3, 0.003, …}
b. {5, -15, 45, -135, 405}
c. {5, 10, 15, 20, …}
d. {27, 32, 37, 42, 47}
Answer: {5, -15, 45, -135, 405}
Step-by-step explanation: In a finite sequence, there's a number of limited terms. And those terms have a common ratio, in this case, the common ration is -3. Notice how 5*-3 is -15, and -15*-3 is 45, and so on until 405.
The finite geometric sequence is {5, -15, 45, -135, 405}.
Thus, option (B) is correct.
A geometric sequence is a sequence in which each term is obtained by multiplying the preceding term by a constant factor called the common ratio.
In the finite geometric sequence {5, -15, 45, -135, 405}
In this sequence, each term is obtained by multiplying (-3) to the previous term.
So, the common ratio
= (-15)/ 5
= -3
Therefore, the sequence is {5, -15, 45, -135, 405}.
Thus, option (B) is correct.

A line has this equation: y = -8x + 8,
Write an equation for the parallel line that goes through (9,7)
[tex]=======================================[/tex]
parallel lines have the same slope; it means that if we have a line with a slope of -8, then the line parallel to the given line has the same slope (-8)
now, we are also given a point that the line passes through:
(9, 7)
we can use point-slope form:
[tex]\pmb{y-y1=m(x-x1)}[/tex]
[tex]\pmb{y-7=-8(x-9)}[/tex] (point-slope form)
now, convert to slope-intercept form, if necessary:
[tex]\pmb{y-7=-8x+72}[/tex]
[tex]\pmb{y=-8x+72+7}[/tex]
[tex]\pmb{y=-8x+79}[/tex]

Two or more friends are collecting pop-can tabs. Natasha has 250 more pop-can tabs then Krystel, in total they have 880. how many pop-can tabs did each collect
Answer:
Krystal collected 315 pop-can tabs while Natasha collected 565 pop-can tabs.
Step-by-step explanation:
Let x be number of pop-can tabs Krystal collected
Krystal: x
Natasha: x + 250
x + x + 250 = 880
2x = 880 - 250
2x = 630
x = 315
Krystal: 315 pop-can tabs
Natasha: 315+250 = 565 pop-can tabs
