Answer: Largest element in the domain is 4
The largest number of packages you can buy is 4
======================================================
Explanation:
1 package costs 8.50*1 = 8.50 dollars
2 packages cost 8.50*2 = 17 dollars
3 packages cost 8.50*3 = 25.50 dollars
and so on. In general
x packages cost 8.50*x = 8.50x dollars
where x is a place holder for a positive whole number (1,2,3,...)
The total amount spent is 8.50x and the budget is $40
This means,
[tex]8.50x \le 40\\\\x \le \frac{40}{8.50}\\\\x \le 4.70588\\\\x \le 4\\\\[/tex]
We round down regardless of how close we are to 5.
If x = 4, then 8.50*x = 8.50*4 = 34
While if x = 5, then 8.50*x = 8.50*5 = 42.5
So we see we go over budget if we buy x = 5 packages.
This makes x = 4 the largest in the domain.
Recall the domain is the set of allowed x inputs. In this case, x is a positive whole number (since we can't buy half a package for instance).

Answer:
[tex] 5x + 12y = -78 [/tex]
or
[tex] y = -\dfrac{5}{12}x - \dfrac{13}{2} [/tex]
Step-by-step explanation:
[tex] y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1}(x - x_1) [/tex]
[tex] y - (-4) = \dfrac{-9 - (-4)}{6 - (-6)}(x - (-6)) [/tex]
[tex] y + 4 = \dfrac{-9 + 4}{6 + 6}(x + 6) [/tex]
[tex] y + 4 = \dfrac{-5}{12}(x + 6) [/tex]
[tex] 12y + 48 = -5x - 30 [/tex]
[tex] 5x + 12y = -78 [/tex]
[tex] 12y = -5x - 78 [/tex]
[tex] y = -\dfrac{5}{12}x - \dfrac{13}{2} [/tex]
Answer:
[tex] 5x + 12y = -78 [/tex]
or
[tex] y = -\dfrac{5}{12}x - \dfrac{13}{2} [/tex]
What will be the equation of a line that is
parallel to y=-X+6 and passes through the
point (-3,1)
Answer:
y=x+4
Step-by-step explanation:
Solve with the point-slope formula: y-y1=m(x-x1). The line is parallel; both slopes are equivalent. Plug in the coordinates we have into the formula, along with the slope from the original equation (-1). To check, we can plug the coordinates back into the equation.
y-(1)=-1(x+3)
y-1=x+3
y=x+4
Check:
(1)=(-3)+4

Luca had a large container of yogurt with 1 and StartFraction 5 Over 8 EndFraction pounds of yogurt left in it. If a serving of yogurt is StartFraction 3 Over 8 EndFraction of a pound, to the nearest whole serving, how many servings of yogurt are in the container? 1 serving 2 servings 4 servings 5 servings
Answer:
4 servings
Step-by-step explanation:
Yogurt in the container = 1 5/8 pounds
A serving = 3/8 pounds
how many servings of yogurt are in the container?
Servings in the yogurt container = total yogurt in the container / yogurt per servings
= 1 5/8 ÷ 3/8
= 13/8 × 8/3
= 13/3
= 4.33
To the nearest whole serving

An electronics superstore normally sells a new smartphone for $200, but it is currently offering a 50% discount off the price. The same phone is available online for $200; the website is offering 25% off the phone, plus another 25% discount off all purchases. Where should you buy the phone to get the better deal? Why?
Answer: They are equal, but if you are buying something else with it,, say a case, the website
Step-by-step explanation:
Website:
1/4 +1/4 = 1/2
Store:
1/2
Answer:
the 50% off is the better deal
Step-by-step explanation:
200 x .50= 100 so on the first phone you save $100
the website you get 25% off so .25 x 200=50 so 200 - 50 =150 then you get another 25% off .25 x 150 =37.50 so 150 - 37.50 = 112.50.

Answer:
Step-by-step explanation:
<a = 85° ( Vertically Opposite Angles )
<b = 180 - 85 = 95° ( Adjacent Angles )
Hope this helps
Plz mark as brainliest!!!!!!!!
Answer:
<a=85
<b=95
Step-by-step explanation:
<a is going to be the same as the other angle is across from it. So <a equals 85 degrees. So now since we know that two parts are 85 degrees we add 85 + 85 and we get 170 degrees. Since the whole thing is 360 degrees we need to subtract the 170 degrees that we already have. So 360-170 is equal to 190 degrees. Now since <b is the same as the angle across from it is we just need to divide the remaining degrees in half. So we take the 190 degrees and divide that in half. When you divide that in half you get 95 degrees. So <b is 95 degrees.
The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?
A. -4
B. -2
C. -1
D. 1
Answer:
The answer would be A. -4
Step-by-step explanation:
If you right it out like x-6=5(x+2), then you distribute the 5, you get: x-6=5x+10. Then subtract x from both sides, you get: -6=4x+10. Subtract 10 from both sides, you get: -16=4x. The all you have to do is divide both sides by 4, and you get: -4=x

FIND VALUE OF X AND OF ANGLE ABC AND ACD
PLS HELP
GEOMETRY
Answer:
see explanation
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ACD is an exterior angle of the triangle, thus
43 + 5x - 48 = 3x + 57 , that is
5x - 5 = 3x + 57 ( subtract 3x from both sides )
2x - 5 = 57 ( add 5 to both sides )
2x = 62 ( divide both sides by 2 )
x = 31
Thus
∠ ABC = 5x - 48 = 5(31) - 48 = 155 - 48 = 107°
∠ ACD = 3x + 57 = 3(31) + 57 = 93 + 57 = 150°
For what value(s) of k will the given relation not be a function?
M = { (15k+9, 4), (3·(4k−1), 6) }
Enter all possible values of k
Given:
The relation is
[tex]M = \{ (15k+9, 4), (3\cdot (4k-1), 6) \}[/tex]
To find:
The value of k for which the relation is not a function.
Solution:
A relation is a function if their exist a unique output or y value for each input or x values.
A relation is not a function if it has two y-values for single x value.
So, the given relation is not a function if x-coordinates of both ordered pairs are equal.
[tex]15k+9=3\cdot (4k-1)[/tex]
[tex]15k+9=12k-3[/tex]
Isolate variable terms.
[tex]15k-12k=-9-3[/tex]
[tex]3k=-12[/tex]
Divide both sides by 3.
[tex]k=-4[/tex]
Therefore, the given relation is not a function for k=-4.

A coyote population has decreased by 168 over the past 3 years. The same number of coyotes were lost each year. Which division expression gives the change in the coyote population each year? A) 168 3 B) 168 −3 C) −168 3 D) −168 −3
Answer:
C, [tex]\frac{-168}{3}[/tex]
Step-by-step explanation:
The number of coyotes is decreasing, which makes it negative, but you can't have a negative year, so the answer must be [tex]\frac{-168}{3}[/tex]
Triangle ABC has vertices at A(-3, 1), B(2, -4), and C(1, 5). It is translated 2 units right and 3 units down to form triangle A’B’C’. A'B'C' is then reflected over the line y = x to form triangle A''B''C''. What are the vertices of triangle A’'B’'C’'? A. A''(2, 1), B''(7,-4), C''(-2, 3) B. A''(2, -1), B''(7,4), C''(-2, -3) C. A''(-1, -2), B''(4,-7), C''(-3, 2) D. A''(-2, -1), B''(-7,4), C''(2, 3)
The vertices of triangle A''B''C'' are A''(-2, -1), B''(-7, 4), and C''(2, 3).
Thus, option (D) is correct.
1. Translation: The original triangle ABC is translated 2 units to the right and 3 units down to form triangle A'B'C'.
To translate a point (x, y) by (a, b), the new coordinates become
(x + a, y + b).
The coordinates of A' would be:
A' = (-3 + 2, 1 - 3) = (-1, -2)
The coordinates of B' would be:
B' = (2 + 2, -4 - 3) = (4, -7)
The coordinates of C' would be:
C' = (1 + 2, 5 - 3) = (3, 2)
2. Reflection over y = x:
Triangle A'B'C' is reflected over the line y = x to form triangle A''B''C''.
To reflect a point (x, y) over the line y = x, the new coordinates become (y, x).
The coordinates of A'' would be:
A'' = (-2, -1)
The coordinates of B'' would be:
B'' = (-7, 4)
The coordinates of C'' would be:
C'' = (2, 3)
Therefore, the vertices are A''(-2, -1), B''(-7, 4), and C''(2, 3).
Thus, option (D) is correct.
