Answer:

y < 50x

Step-by-step explanation:

In order to graph this inequality, you first need to identify the important word(s) here to find the inequality sign; in this case, it would be "maximum of $50" a month. Since it's a maximum of $50 a month (or less than $50 a month), you can write it as:

Where m is months and c is total cost, c < 50m

If you need to graph this, you can write it as y < 50x. The cost is y since it's the output, and months is x since that's the input.

Answer:

x = -3, y = 9

Step-by-step explanation:

-5x - 5y = -30

x - y = 6

x = -y + 6

10x + 3y = -3

10(-y + 6) + 3y = -3 (plug in x from the previous equation)

60 - 10y + 3y = -3

60 - 7y = -3

-7y = -63

y = 9

x = -y + 6

x = -(9) + 6

x = -3

Answer:

Step-by-step explanation:

t=1.5+0.25m, if t=25 then

1.5+0.25m=25

0.25m=23.5

m=94

So she drove 94 miles.

The cost of each brownie is $1.25

Let the cost of each brownies be x

If she buys 12 brownies and each brownie costs the same amount, the cost of 12 brownies will be 12x

To find the value of x;

39.99 = 24.99 + 12x

12x =  15

x = 15/12

x = $1.25

Hence the cost of each brownie is $1.25

Answer:

x = 9

Step-by-step explanation:

Opposite sides of a parallelogram are equal.

16x - 15 = 11x + 30          Subtract 11x from both sides

16x - 11x - 15 = 30           Combine the left

5x - 15 = 30                    Add 15 to both sides

5x = 30 + 15                   Combine the right

5x = 45                           Divide by 5

5x/5 = 45/5

x = 9

Answer:

A

Step-by-step explanation:

The true statement is

A 99% confidence interval for will include the value 1.

The range of values that we observe in our sample and for which we anticipate finding the value that accurately reflects the population is referred to as a confidence interval.

Given:

[tex]H_0: \mu = 1\\H_\alpha : \mu \neq 1[/tex]

P= 0.022

If the P- value is smaller than significance level, then the null hypothesis is rejected.

P< 0.05 - 5% Reject [tex]H_0[/tex]

P> 0.01 = 1% Fail to Reject [tex]H_0[/tex]

A 95% Confidence interval correspond with a significance test at the 5%

significance level.

A 99% Confidence interval correspond with a significance test at the 1%

significance level.

If the Significance test was Significant then the interval does not contain the value mentioned in the Hypothesis.

95% CI does not contains 1.

99% CI contains 1.

Answer:

x = 5 or x = -5

Step-by-step explanation:

| a b |

| c d |

det = ad - bc

| x 4 |

| 3 x |

det = x * x - 4 * 3 = x^2 - 12

x^2 - 12 = 13

x^2 = 25

x^2 - 25 = 0

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

x = 5 or x = -5

Length is 7, Permimeter is 28

Step-by-step explanation:

Perimeter=4×side

(8x-28)=4×x [let length be x]

8x-28=4x

8x-4x=28

4x=28

x=28÷4

x=7

Length = x = 7

Perimeter=(8x-28)

Answer:

The amount Lilian needs to invest is $5,160

Step-by-step explanation:

The parameters of the amount Lilian is going to invest in an account are;

The interest rate the account pays = 5.7%

The final amount the investment is expected to reach after the given time period = $7,600

The number of years of the investment = 7 years

The formula for compound interest is presented as follows;

[tex]A = P \cdot \left(1 + \dfrac{r}{n} \right)^{n\cdot t}[/tex]

Where;

A = The final amount = $7,600

P = The amount Lilian is to invest

r = The interest rate = 5.7% = 0.057

n = The number of times the interest is applied per time period = 1

t = The number of period that passes = 7 (years)

Therefore, we get;

[tex]7,600 = P \cdot \left(1 + 0.057 \right)^{7}[/tex]

∴ P = 7,600/(1 + 0.057)⁷ = 5,155.7123754

The amount Lilian needs to invest (rounded to the nearest ten dollars) for the value of the account to reach $7,600 in 7 years, P = $5,160

Answer:

5/36 is your answer.

Step-by-step explanation:

If the red die shows a "2", then the blue die must take on the values from the set {2,3, 4, 5, 6} in order for the sum of both dice to be larger than 4.

1+2=3

2+3 = 5

2+4 = 6

2+5 = 7

2+6 = 8

There are 6*6 = 36 total ways to roll two dice and exactly 5 ways to get the conditions stated above. The probability of getting a sum greater than 2 is 5/36

The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

Cindy throws one red and one blue regular (six-sided) fair dice. The total number of events will be

Total events = 6 x 6 = 36

The probability that the sum of the two dice is greater than 2 will be given as

P = 1 - 1 / 36

P = 35 / 36

The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.

Answer and Step-by-step explanation:

For this shape, we have to draw a line that goes through the point that is inside of the shape from top to bottom.

This creates a square and two triangles.

The area formula for a triangle is A = [tex]\frac{bh}{2}[/tex]

The area of a square is A = b*b

Half of 3 is 1.5.

Triangles (Area combined):

Since there are two triangles that are the same, we only need to find the area of of 1 triangle, and not divide by 2.

A = 3 × 1.5 = 4.5

Square:

A = 3 × 3 = 9

Now, we add them together to get the total area of the figure.

9 + 4.5 = 13.5

The area of the figure is 13.5 [tex]in^{2}[/tex].
