To find the weight of Carmen's pet rabbit, an equation is set up: 2w - 1 = 9, where w represents the unknown weight of Carmen's rabbit. Solving the equation, we find that Carmen's rabbit weighs 5 pounds.

To find the weight of Carmen's pet rabbit, we first need to translate the given information into a mathematical equation. The problem states that Angelo's pet rabbit weighs 1 pound less than twice the weight of Carmen's pet rabbit and Angelo's rabbit weighs 9 pounds. Let's denote the weight of Carmen's rabbit as w. The relationship can be written as:

2w - 1 = 9

To solve for w, we add 1 to both sides of the equation:

2w - 1 + 1 = 9 + 1

2w = 10

Now, we divide both sides by 2 to get the weight of Carmen's rabbit:

2w / 2 = 10 / 2

w = 5

Therefore, Carmen's pet rabbit weighs 5 pounds.

Answer: A

Step-by-step explanation:

For this case we must simplify the following expression:

[tex]\sqrt [5] {224x ^ {11} * y ^ 8}[/tex]

We follow the steps below:

We rewrite 224 as the product of: 32 * 7

[tex]\sqrt [5] {32 * 7 * x ^ {11} * y ^ 8} =[/tex]

We rewrite [tex]32\ as\ 2 ^ 5, x^{11}\ as\ x * x^{10}:[/tex]

[tex]\sqrt [5] {2 ^ 5 * 7 * x ^ {10} * x * y ^ 8} =[/tex]

We rewrite [tex]x^{10}[/tex] as [tex](x ^ 2) ^ 5,[/tex] we also rewrite [tex]y ^ 8[/tex] as [tex]y ^ 5 * y ^ 3:[/tex]

[tex]\sqrt [5] {2 ^ 5 * 7 * (x ^ 2) ^ 5 * x * y ^ 5 * y ^ 3} =[/tex]

We reorder:

[tex]\sqrt [5] {2 ^ 5 * (x ^ 2) ^ 5 * y ^ 5 * 7 * x * y ^ 3} =\\\sqrt [5] {(2 * x ^ 2 * y) ^ 5 * (7 * x * y ^ 3)} =[/tex]

We take the terms of the radical considering that: [tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

Answer:

Plain rolls: $16

Shinny rolls: $20

Step-by-step explanation:

So, we have 2 equations to start with, let p = plain rolls and s = shinny rolls:

1)  8p + 10s = 328

2) 9p + 2s = 184

We need to isolate one variable, usually I go for the one with the lowest multiplicative... so let's go for the '2s' and isolate the s from equation 2.

2s = 184 - 9p

3) s = (184 - 9p) / 2

And let's place that s equivalent into the first equation:

8p + 10 (184 - 9p)/2 = 328

8p + 5(184 - 9p) = 328

8p - 45p + 920 = 328

-37p = -592

p = 16

Then we go into any of the 3 equations to get the value of s.  Let's take the 3rd equation, it will be simpler:

s = (184 - 9p) / 2 = (184 - 9*16) / 2

s = (184 - 144)/2 = 40/2 = 20

Then last step, we enter the values for s and p in one of the first equations to validate it.  We haven't worked with first equation, so let's use that one:

8p + 10s = 328

8 (16) + 10 (20) = 328

128 + 200 = 328

328 = 328

Answer:

[tex]\boxed{\text{[2, 33]}}[/tex]

Step-by-step explanation:

The range is the spread of the y-values (minimum to maximum distance travelled).

The minimum is 2 mi, and the maximum is 33 mi, so the range is from 2 to 33.

In interval notation, the range is [tex]\boxed{\textbf{[2, 33]}}[/tex]

Answer:

31

Step-by-step explanation:

31

The range is the difference between the largest and smallest number.

range = biggest − smallest = 33 − 2 = 31

Step-by-step explanation:

The tenth column value is the first after the decimal point, that is 3

To round the required value of 3

• If the value following 3  ≥ 5, round 3 up to 4

• If the value following 3 < 5 , then leave as 3

Here the value following 3 is 5 so round 3 up to 4

All other digits remain unchanged.

Answer:x2_>16 B.

Step-by-step explanation:

For this case we will show that the correct option is option C.

[tex]x ^ 2 \leq16[/tex]

We find the value of the variable "x":

We apply root to both sides of the equation to eliminate the exponent:

[tex]x \leq \pm \sqrt {16}\\x \leq \pm4[/tex]

We found the first solution with the positive value:

[tex]x \leq4[/tex]

We use the negative value to find the other solution. Since it is an inequality, the sign of the inequality changes in the negative portion of the solution.

[tex]x \geq-4[/tex]

So, the roots are:

[tex]x_ {1} \geq-4\\x_ {2} \leq + 4[/tex]

The solution is given by the values of "x" greater than or equal to -4 and less than or equal to 4

2(x-8)=8

x=12

Step-by-step explanation:

The equation for the given statement is 2(x-8)=2.

The given statement "Twice the difference of a number and 8 is equal to 2 ​

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, the difference between a number and 8 can then be written as 'x-8'. Twice that amount would be 2(x-8). If it's equal to 2, you can say 2(x-8)=2.

Therefore, the equation for the statement is 2(x-8)=2.

Answer:

y > –5x + 3

Step-by-step explanation:

we know that

1) The solution of the inequality is the shaded area above the dashed line

so

The linear inequality could be

y > –5x – 3

y > –5x + 3

y > –3x + 5

2) The slope of the dashed line is negative ----> the three options have slope negative

3) The y-intercept of the dashed line is (0,3)

therefore

The linear inequality is

y > –5x + 3

Answer:

[tex]y>-5x+3[/tex]

Step-by-step explanation:

To find the linear inequality , Let pick two points from the graph

Lets pick (0,3) and (1,-2)

Lets find out slope using the points

[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]slope =\frac{-2-3}{1-0}=-5[/tex]

Slope m= -5

y intercept b= 3

Equation of the line is y=mx+b

[tex]y=-5x+3[/tex]

Now we look at the shaded part. we use test point (0,0)

(0,0) is not in the shaded region

[tex]y=-5x+3[/tex]

[tex]0=-5(0)+3[/tex]

0 >3 is false

sec(x)*cos(x) + cos(x)-1/(sec(x))

We know that sex(x) = 1/(cos(x))

substitute it in our expression.

1/(cos(x)) * cos(x) + cos(x) - 1/(1/cos(x)) = 1+cos(x) - cos (x)= 1

ANSWER

A. 1

EXPLANATION

The given trigonometric expression is

[tex] \sec(x) \cos(x) + \cos(x) - \frac{1}{ \sec(x) } [/tex]

Recall and use the following reciprocal identities.

[tex] \frac{1}{ \sec(x) } = \cos(x) [/tex]

and

[tex] \sec(x) = \frac{1}{ \cos(x) } [/tex]

When we apply these identities, we get

[tex] \frac{1}{ \cos(x) } \times \cos(x) + \cos(x) - \cos(x) [/tex]

This simplifies to:

Answer:

A) exponential

Step-by-step explanation:

It is in a curving pattern which indicates exponential. Linear is a straight line.

The best-fitting regression model for the considered data plot is given by: Option A: Exponential.

When the data shows some trend, either linear (making a line), or non-linear (a predictable curve), we fit a mathematical curve on that data set, as a representative of the pattern in that data set, to predict the output based on the inputs.

The considered plot is not forming a straight line(so no linear fitting), but we can see that a smooth curve can be fitted in the considered data. Since the exponential functions' graph approximately goes the same way (for positive exponent, and increasing value of output).

Thus, the best-fitting regression model for the considered data plot is given by: Option A: Exponential.

Answer:

Step-by-step explanation:

To find out how much money Gayle initially had, we solved the two equations provided by the problem: G + 20 = 2(J + 20) and J + 20 = G + 20 - 50. Solving these equations, it was found that Gayle initially had $90.

The question is asking us to figure out how much money Gayle had before their mother gave them each $20. Let's denote the amount of money Jerry initially had as J and the amount of money Gayle initially had as G. According to the problem, after the mother gave them $20 each, Gayle had twice the amount of Jerry's, which mathematically translates to G + 20 = 2(J + 20). Likewise, Jerry had $50 less than Gayle, which can be written as J + 20 = G + 20 - 50. Thus we are given a system of two equations that we can solve simultaneously.

Both equations can be simplified to G = 2J + 20 and J = G - 50. By substituting J = G - 50 in the first equation, we can solve for G to get G = 2(G - 50) + 20 which further simplifies to G = $90. Thus, Gayle initially had $90.
