Answer:

How much they make  = 20,000

Expenses  = 15,000

Profit  = 5,000

Step-by-step explanation:

Well this question isn't very clear since it didn't state what the original cost for one iphone is. I think they are assuming one iphone to be 200 dollars or the sold amount, but this information is not directly stated. Anyways....

How much they make  100x200 = 20,000

Expenses  100(200-50) = 15,000

Profit  20,000 - 15,000 = 5,000

Answer:

Marty's with a slope of 1/3

Step-by-step explanation:

The functions Marty and Ethan wrote are analyzed the find the slope of each of the function

The equation Marty wrote is presented here as follows;

[tex]y + 3 = \dfrac{1}{3} \cdot\left (x + 9 \right)[/tex]

Marty's equation can be written in slope and intercept form, y = m·x + c, as follows;

[tex]y = \dfrac{1}{3} \cdot\left (x + 9 \right) - 3[/tex]

[tex]y = \dfrac{1}{3} \cdot x + \dfrac{9}{3} \right) - 3 = \dfrac{1}{3} \cdot x + 0[/tex]

[tex]y = \dfrac{1}{3} \cdot x[/tex]

By comparison, the slope of the function, m = 1/3

[tex]\therefore \ the \ slope \ of \ Marty's \ function, \ y + 3 = \dfrac{1}{3} \cdot\left (x + 9 \right), \ m =\dfrac{1}{3}[/tex]

Marty's function has a slope of m = 1/3

Ethan has the following two column table;

[tex]\begin{array}{rl}x&y\\-4&9.2\\-2&9.6\\0&10\\2&10.4\end{array}[/tex]

The slope, m, of the data in the above table is given as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Taking any two points, (x₁, y₁) = (-4, 9.2), and (x₂, y₂) = (2, 10.4), we get;

[tex]Slope, \, m =\dfrac{10.4-9.2}{2-(-4)} = \dfrac{1.2}{6} = \dfrac{1}{5}[/tex]

Ethan's function has a slope of m = 1/5

Therefore;

Marty's slope of 1/3 is larger, given that 1/3 > 1/5.

Answer:

C. Marty’s with a slope of 1/3

Did the test and got it correct

Answer:

This is incorrect as 1/8 plus 3/5 is 29/40

Step-by-step explanation:

:)

Answer:

Susan is incorrect.

Step-by-step explanation:

First, what we do is add 1/8 + 3/5

Our result will be 4/13 because 1+3 = 4 would be as the numerator, and 8+5 = 13 would be as the denominator.

We can't simplify 4/13.

If we did increase the number, however, it would be 8/26, which is not close to the answer.

Therefore, Susan is incorrect.

Answer:

x ≈ 29.4 ft

Step-by-step explanation:

The model is a right triangle.

Using the tangent ratio

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{35}[/tex] ( multiply both sides by 35 )

35 × tan40° = x , then

x ≈ 29.4 ft ( to 1 dec. place )

Answer:

Her first exam score was a 78, her second exam score was a 89, and his third exam score was a 94.

Step-by-step explanation:

Use the formula for the mean: sum of elements / number of elements

Let x represent her first exam score.

Her second exam score can be represented by x + 11, since it was 11 points better than her first.

Her third exam score can be represented by (x + 11) + 5, since it was 5 points better than her second.

Plug in all of these expressions into the mean formula. Plug in 87 as the mean, and plug in 3 as the number of elements (since there are 3 scores):

mean = sum of elements / number of elements

87 =  ( (x) + (x + 11) + (x + 11) + 5 ) / 3

Add like terms and solve for x:

87 = (3x + 27) / 3

261 = 3x + 27

234 = 3x

78 = x

So, her first score was a 78.

Find her second score by adding 11 to this:

78 + 11 = 89

Find her third score by adding 5 to the second score:

89 + 5 = 94

Her first exam score was a 78, her second exam score was a 89, and his third exam score was a 94.

Take the 1st equation & solve it :-

[tex]3x - 1 = 7 \\ 3x = 7 + 1 \\ 3x = 8[/tex]

Now, take the second equation :-

[tex]3x = 8[/tex]

[You can't further solve this equation]

So, from the 2 solved equations we can see that,

[tex]\large\bold{3x = 8 \ is \ equivalent \ (=) \ 3x = 8 }[/tex]

✐ The answer will be ⇻ Yes, 3x – 1= 7 and 3x = 8 are equivalent to each other.

24÷4=6. x=4. x=6

Answer:

Becky's age is equal to 20.

Step-by-step explanation:

The given expression is :

(7+11)-(8÷2)

Using Bodmas rule to solve it furthur,

(18)-4 = 14

According to the given condition, let the age is A.

The value is 6 less than her age,

14 = A-6

or

14+6 = A

A = 20

Hence, Becky's age is equal to 20.

Answer:

16(sin 30degrees) = BC

BC = 8

Answer: It will have a minimum.

Answer:

x = -3 ; y = -6

Step-by-step explanation:

x = y + 3

-2x + 4y = -18

-2(y+3) + 4y = -18

-2y -6 + 4y = -18

2y = -12

y = -6

x = -6+3

x = -3

Answer:

x = -3    y = -6

Step-by-step explanation:

x = y + 3

x - 3 = y

-2x + 4(x - 3) = -18

-2x + 4x - 12 = -18

2x = -6

x = -3

x = y + 3

-3 = y + 3

-6 = y

Answer: 4:5

Step-by-step explanation:

32 and 40 share a common factor of 8. We can divide both of them by 8 so that the ratio stays the same value and it'll be in it's simplest form.

[tex]\frac{32}{8} =4\\\frac{40}{8} =5[/tex]

Answer:

Table 1

Step-by-step explanation:

The slope of a line (m) passing through two points A(x₁, y₁) and B(x₂, y₂) is given by:

m = (y₂ - y₁) / (x₂ - x₁)

a) From table 1, we can select two points. Let us select point (-3, 2) and point (1, 2). Hence the slope is:

[tex]m=\frac{2-2}{1-(-3)}=0[/tex]

b) From table 2, we can select two points. Let us select point (-3, 3) and point (1, -1). Hence the slope is:

[tex]m=\frac{-1-3}{1-(-3)}=-1[/tex]

c) The graph passes through point (0, 0) and (3,3). Hence:

[tex]m=\frac{3-0}{3-0}=1[/tex]

d) The graph passes through point (-2, 4) and (-2,0). Hence:

[tex]m=\frac{0-4}{-2-(-2)}=\infty[/tex]

Answer:

D

Step-by-step explanation:

Since there is a negative sign, the graph is a n shaped quadratic curve and hence, there can only be maximum point. Hence we can eliminate A and C.

For a curve in the completing the square form y = (x+a)²+b, the turning points are (-a,b). Hence in this case, turning point is at (-5, 3).

Hence the correct option is D
