Answer:

The opposite of -10·t and t - 10·t is t

Step-by-step explanation:

1) The opposite of 4·x and -5 + 4·x is given as follows;

-4·x + (-5 + 4·x) = -4·x -5 + 4·x = -4·x + 4·x - 5 = 0 - 5 = -5

2) The opposite of -10·t and t - 10·t is given as follows;

-(-10·t) + (t - 10·t) = 10·t + t - 10·t = 10·t - 10·t + t = 0 + t = t

3) The opposite of (-7 - 4·v) and -4·v is given as follows;

-(-7 - 4·v) + (-4·v) = -1 × (-7 - 4·v) - 4·v  = 7 + 4·v - 4·v  = 7 + 0 = 7

Step-by-step explanation:

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.

Step-by-step explanation:

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:

Step-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.

Step-by-step explanation:

(3x-2y=-16)first put in standard form y=mx+b

(-2y=-3x-16) divide both sides by -2

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

Step-by-step explanation:

If the original number is zero or positive, then the absolute value of the number is simply the original number. If the number is negative, then the absolute value is the original number with the negative sign stripped away. For example: Notice that an equation with an absolute value represents two possibilities.  could i get brainliest please

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.

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.

Answer: it’s a

Step-by-step explanation:

Answer: A for the first part and B for the second part

Step-by-step explanation:

Answer:

a. Monthly profit is

(x-35)(500-x)

b. given x = 85, the profit is 20,750 pesos

Step-by-step explanation:

a. The monthly profit is the selling price - cost price

The cost price for the number of dolls made will be ;

35(500-x)

The value of the amount we are selling all is;

x(500-x)

So the monthly profit would be;

x(500-x)-35(500-x)

= (x-35)(500-x)

b. Given the selling price we 85 , we want to calculate the monthly profit

From

what we have, x will be 85

Substituting in the equation we have for A above, we have that;

(85-35)(500-85)

= 50* 415 = 20,750 pesos

Answer:

25% loss

Step-by-step explanation:

21 is 75% of 28, because 7*3 = 21 and 7*4 = 28

100%-75%=25%

Hope this helps!

Answer:

the answer is 50 %

Step-by-step explanation:

C.P x (100+ (P/L) ) over 100 = S.P

C.P x 50 over 100 = 8500

C.P = 8500 x 100 over 50 = 17000 .Rs.

Answer:

It is (9,-3) because x increased by 1 unit and y increased by 4 units.

Answer:

[tex](9,-3)[/tex]

Step-by-step explanation:

[tex](8,-7)[/tex]

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.

Answer:

456% increase

Step-by-step explanation:

Step one:

given data

Hubba Bubba Bubble gum  was $0.25 30 years ago

Today it costs $1.39.

Required

The percentage increase

Step two:

Percentage increase= change in price/ old price *100

Percentage increase= 1.39-0.25/0.25 *100

Percentage increase=1.14/0.25 *100

Percentage increase=4.56*100

Percentage increase=456%

Answer:

The rule for the linear function wil be:

Step-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

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:

Answer:  [tex]\frac{\sqrt{3}}{2}[/tex]

======================================================

Explanation:

The symbol [tex]\theta[/tex] is the greek letter theta. It's often used in trigonometry for angles.

In this case, [tex]\theta = 30^{\circ}[/tex]

So,

[tex]\cos(\theta) = \cos(30^{\circ}) = \frac{\sqrt{3}}{2}[/tex]

You'll need to use a reference sheet or the unit circle to determine the value of cos(30). Or you could use a 30-60-90 triangle template.

When using the unit circle, look in the upper right quadrant (which is quadrant 1). The angle 30 degrees is in this quadrant. Locate the terminal point and note how [tex]\frac{\sqrt{3}}{2}[/tex] is the x coordinate of the terminal point. This is due to [tex]x = \cos(\theta)[/tex]

Side note: [tex]\frac{\sqrt{3}}{2} \approx 0.866025[/tex]
