5. Company “A” charges $80 a month for

of Data. Company “B” charges $60 a
month for their cell phone plan and $10 for
a 100MB of Data. How many mega bytes
of data used would make the cost from
either company equal?
Answers
Answer:
400 megabytes of data used will make the cost from either company equal.
Step-by-step explanation:
Given that:
Per month charges of Company A = $80
Charges of 100 MB = $5 = [tex]\frac{5}{100}=\$0.05\ per\ MB[/tex]
Let,
x be the number of MBs consumed.
y be the total charges.
y = 0.05x+80
Per month charges of Company B = $60
Charges of 100 MB = $10 = $0.1 per MB
y = 0.1x+60
For equal charges;
0.05x+80 = 0.1x + 60
80-60 = 0.1x-0.05x
20 = 0.05x
[tex]\frac{0.05x}{0.05}=\frac{20}{0.05}\\x=400[/tex]
Hence,
400 megabytes of data used will make the cost from either company equal.
1.5:4=9:(2y+5)
Solve for y
Answers
Answer:
y = 9.5
Step-by-step explanation:
Express the ratios in fractional form, that is
[tex]\frac{1.5}{4}[/tex] = [tex]\frac{9}{2y+5}[/tex] ( cross- multiply )
1.5(2y + 5) = 36 ( divide both sides by 1.5 )
2y + 5 = 24 ( subtract 5 from both sides )
2y = 19 ( divide both sides by 2 )
y = [tex]\frac{19}{2}[/tex] = 9.5

A rectangular soccer field may have a width between 50 and 100 yards and a length
between 100 and 130 yards. One particular soccer field has a perimeter of 320 yards. Its
length measures 40 yards more than its width. What are the dimensions of this field?
The length is___yards.
The width is____yards.
Answers
Answer:
[tex]perimeter = 2(l + w) \\ but \: length = 40 \times width \\ perimeter = 2(40w + w) \\ p = 2(41w) \\ 320 = 2(41w) \\ w = \frac{320}{(2 \times 41)} \\ w = 3.902 \: yards \\ length = 40 \times w \\ = 40 \times 3.902 \\ l = 156.08 \: yards[/tex]
9514 1404 393
Answer:
length: 100 yardswidth: 60 yardsStep-by-step explanation:
Let w represent the width of the field. Then the length is (w+40), and the perimeter is ...
P = 2(L +W)
320 = 2((w+40) +w) . . . . fill in values
160 = 2W +40 . . . . . . . . . divide by 2, collect terms
80 = w +20 . . . . . . . . . . . divide by 2
60 = w . . . . . . . . subtract 20
w+40 = 100
The length is 100 yards; the width is 60 yards.

y=3/2x+8
Answer:
C
Step-by-step explanation:
By opposite I'm going to assume they mean the perpindicular line
To do this you first need to convert the function into linear form
So we have 3x-2y=-16
and so we can add 2y and 16 to both sides to get
3x+16=2y
then divide by 2 to get
3/2x+8=y
This is our function in linear form but now we need the opposite by taking the negative reciprocal of the slope
This means our near equation is now -2/3x+8 while none of them give that as an option directly if you simplify C it will match

Determine whether the function f(x) = -9.5 + 6 + x² is even, odd or neither.
Answers
Answer:
The function f(x) = -9.5 + 6 + x² is neither odd or even.
Step-by-step explanation:
We know that a function is termed as 'even' when
f(-x) = f(x) for all x
We know that a function is termed as 'odd' when
f(-x) = -f(x) for all x
Given the function
f(x) = -9.5x⁵ + 6 + x²
substitute x with -x
f(-x) = -9.5(-x)⁵ + 6 + (-x)²
as (-x)⁵ = -x⁵, so
f(-x) = -(-9.5x)⁵ + 6 + (-x)²
Apply exponent rule: (-a)ⁿ = aⁿ, if n is even
f(-x) = -(-9.5x)⁵ + 6 + x²
Apply rule: -(-a) = a
f(-x) = 9x⁵ + 6 + x²
As
f(-x) ≠ f(x) ≠ -f(x)
Therefore, the function f(x) = -9.5 + 6 + x² is neither odd or even.

The local comic book store is having a closeout sale on their last 375 comic books and Pokémon cards. They are selling single issue comics for $5.79 and Pokémon boosters packs for $3.35. Their goal is to make $1345 to break even on their current final cost. Approximately how many of each do they need to sell?
Answers
Answer:
36 comic books and 339 Pokemon cards
Step-by-step explanation:
Let number of comic books be [tex]x[/tex] and number of Pokemon cards be [tex]y[/tex].
Total number of comic books and Pokemon cards is [tex]375[/tex]. So we get the equation
[tex]x+y=375\\\Rightarrow y=375-x[/tex]
Cost of one comic book is $5.79 and one Pokemon card is $3.35.
They need to make $1345 so we get the equation
[tex]5.79x+3.35y=1345\\\Rightarrow 5.79x+3.35(375-x)=1345\\\Rightarrow 5.79x-3.35x+3.35\times 375=1345\\\Rightarrow x=\dfrac{1345-3.35\times 375}{5.79-3.35}\\\Rightarrow x=36.37\approx 36[/tex]
[tex]y=375-x=375-36\\\Rightarrow y=339[/tex]
So, they need to sell approximately 36 comic books and 339 Pokemon cards.

Write the rule for the linear function. Remember a function rule is written using f(x)
Answers
Answer:
The rule for the linear function wil be:
f(x) = xStep-by-step explanation:
We know that linear function can be represented using the slope-intercept formula
y = mx+b
where m is the slope and b is the y-intercept
Given the function is linear
Taking two points
(0, 0)(1, 1)Finding the slope between (0, 0) and (1, 1)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [1 - 0] / [1 - 0]
= 1 / 1
= 1
Thus, the slope of the line = m = 1
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = 1 and b = 0 in the slope-intercept form of linear function
y = mx+b
y = (1)x + 0 ∵ m = 1, b = 0
y = x
f(x) = x ∵
Therefore, the rule for the linear function wil be:

If it moves right, add the value to the x-coordinate. If it moves left, subtract the value from the x-coordinate. In this case, because the point was translated 1 unit right, we add 1 to the x-coordinate 8.
[tex](9,-7)[/tex]
If it moves up, add the value to the y-coordinate. If it moves down, subtract the value from the y-coordinate. In this case, because the point was translated 4 units up, we add 4 to the y-coordinate.

Use the figures to complete the statements proving the converse of the Pythagorean theorem.
Drag and drop a phrase, value, or equation into the box to correctly complete the proof.
To prove the converse of the Pythagorean theorem, we must show that if △ABC has sides of a, b, and c such that a² + b² = c² , then △ABC is a right triangle.
Define △DEF so that it is a right triangle with sides a, b, and hypotenuse x. By the Pythagorean theorem, a² + b² = x² .
Since a² + b² = c² and a² + b² = x², it must be true that c² = x². Since sides of triangles are positive, then we can conclude that Response area. Thus, the two triangles have congruent sides and are congruent.
Finally, if △ABC is congruent to a right triangle, then it must also be a right triangle.

Step-by-step explanation:
By rotating a figure,
The length of its sides remain the same.
Therefore line AB = line A'B'.
=> 5x - 14 = 4x + 4
=> x = 18
Hence, line AB = 5(18) - 14 = 76.
Answer:
The length of AB = 76 units.
Step-by-step explanation:
We know that Rotations, just like reflections, and translations, are termed isometric.
In other words, these transformations do not alter the size of the figure.
If the size and shape of the figure are not altered, then the figures are termed as congruent.
Given
AB = 5x-14
A'B' = 4x+14
As A'B'C'D' is obtained by rotating ABCD,
so
AB = A'B'
substituting AB = 5x-14 and A'B' = 4x+14
5x-14 = 4x+14
5x - 4x = 14+14
x = 18
Thus,
AB = 5x-14
substitute x = 18
AB = 5(18)-14
AB = 90 - 14
AB = 76
Therefore, the length of AB = 76 units.
