Answers

Answer 1

The solution will be the point of intersection of the lines and since the lines are parallel to each other, there is no solution

System of inequality

Inequality are expressions not separated by an equal sign. Given the following inequalities

2x - y > 4

2x - y < -2

The lines for both inequality must be dashed since they do not include equal sign. The first line will be shaded in the upper part while the second in the lower portion

Answers

Quadrilaterals are plane shapes with four sides. Thus, the required answers are:

a) The first shape is a right trapezoid.

b) The second shape is a parallelogram.

The given properties are that of a quadrilateral, thus both shape is a quadrilateral. A quadrilateral is a family of shapes that have four straight sides. Examples include squares, rhombus, kites, etc.

A. Given that the shape has one right angle and parallel sides. Then considering the given properties, the most likely shape is a right trapezoid.

A right trapezoid is a type of trapezium that has one right angle, and a pair of parallel sides. Thus the shape here is a right trapezoid.

Other shapes could be ruled out by comparing their properties with the properties of the shape given in the question.

B. The properties of the required shape as given are: it has two pairs of congruent opposite sides, and 2 pairs of opposite parallel sides. Thus the most likely shape required here is a parallelogram. A parallelogram is a shape with parallel and congruent opposite sides, and no right angle.

Other shapes could be ruled out by comparing their properties with the properties of the shape given in the question.

Which type of parent function is f(x) = -
1/?
O A. Absolute value
OB. Reciprocal
OC. Square root
OD. Linear

Answers

Answer: B. Reciprocal

Step-by-step explanation:

This is a fact.

The parent function represented by f(x) = -1/x is the reciprocal function.

Therefore, the correct answer is option B.

Reciprocal functions, also known as rational functions, are defined by an algebraic expression where the dependent variable is in the denominator. In this case, the dependent variable is x, and it appears in the denominator as 1/x.

The negative sign in front of the fraction simply indicates that the function is reflected over the x-axis.

The general form of a reciprocal function is f(x) = a/x, where "a" is a constant. In the given function f(x) = -1/x, a is equal to -1.

In the case of f(x) = -1/x, the graph of the function is a hyperbola that opens downwards in the first and third quadrants. It approaches the x-axis as x moves towards positive or negative infinity, and it moves away from the x-axis as x approaches 0.

Therefore, the correct answer is option B, the reciprocal function.

Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues. (Assume that n begins with 1.)
{2, 6, 10, 14, 18, . . . }

Answers

The formula for the general term of the sequence is Tn = 4n - 2

How to determine the formula?

The above sequence is an arithmetic sequence with the following features:

First term, a = 2Common difference, d = 4 i.e. 6 - 2

The formula for the general term is calculated using:

Tn = a + (n - 1) * d

This gives

Tn= 2 + (n - 1) * 4

Answers

The perimeter of the original rectangle is 17.6mm. The side length of the enlarged rectangle is 23.22mm and the perimeter of the enlarged rectangle is 95.04mm

Perimeter of a rectangle

The formula for calculating the perimeter of a rectangle is expressed as;

P = 2(l +w)

If the smaller rectangle has a length of 4.3 millimeters and width of 4.5 millimeters while a larger rectangle has a length of x millimeters and width of 24.3 millimeters, then;

4.3/x = 4.5/24.3

Cross multiply

4.5x = 104.49

x = 23.22mm

Perimeter of original rectangle = 2(4.3 + 4.5)

Perimeter of original rectangle = 17.6mm

Perimeter of enlarged rectangle = 2(23.22 + 24.3)

Perimeter of enlarged rectangle = 95.04mm

The equation y minus 1 = negative 7 (x minus 3). is written in point-slope form. What is the y-intercept of the line?

Answers

Answer:

(0, 22)

Step-by-step explanation:

So you have the equation:

[tex]y-1=-7(x-3)[/tex]

So first let's define what the "y-intercept" is. The y-intercept, of a line is like the name implies, when the line intercepts or "passes" the y-axis. And if you were to take any point on the y-axis, the y-value may vary, but there is one value that doesn't change, and that's the x-value. the x-value is always going to be zero, no matter where you are on the y-axis. So to find the y-intercept simple plug 0 in as x. This gives you the equation:

[tex]y-1 = -7(0-3)[/tex]

[tex]y-1 = -7(-3)[/tex]

[tex]y-1=21[/tex]

[tex]y=22[/tex]

So the y-intercept is at (0, 22)

How to determine the expressions

1. The two expressions could be gotten thus;

6(m + 2 + 7m)

Collect like terms in the bracket

6 ( 8m + 2) ⇒ first expression

6(m + 2 + 7m)

Expand the bracket

6m + 12 + 42m

Collect like terms

6m + 42m + 12

48m + 12 ⇒ second expression

Part B:

6(m + 2 + 7m) = 48m + 2

Expand the bracket

6m + 12 + 42m = 48m + 2

Collect like terms

48m - 48m = 12 - 12

0 = 0

Part C:

Let the expression from A be 6 ( 8m + 2)

6(m + 2 + 7m) = 6 ( 8m + 2)

Let the number be m = 1

Substitute the values

6(1 + 2 + 7(1) ) = 6 (8(1) + 2)

The table of values is

x -1 0 1 2 3 4 5 6

f(x) -13 -7 -1 11 35 77 143 139

How to form the table?

The function is given as:

f(x) = x³ +5x-7

And the values of x are

x = -1, 0, 1, 2, 3, 4 5 and 6.​

Substitute these values in the function

f(-1) = (-1)³ +5(-1) - 7 = -13

f(0) = (0)³ +5(0) - 7 = -7

f(1) = (1)³ +5(1) - 7 = -1

f(2) = (2)³ +5(2) - 7 = 11

f(3) = (3)³ +5(3) - 7 = 35

f(4) = (4)³ +5(4) - 7 = 77

f(5) = (5)³ +5(5) - 7 = 143

f(6) = (6)³ +5(6) - 7 = 239

Hence, the table of values is

The confidence interval is (-1.1059, 7.70459).

What is confidence interval in statistics?

Image result for what is confidence interval

A confidence interval is the mean of your estimate plus and minus the variation in that estimate.

The sample mean is M=3.3

The sample size is N=44

So, σM= s/√N = 16.6/ √44

= 16.6/ 6.633

= 2.621

and, the degree of freedom

df= n-1

=44-1

=43

So, The t-value for a 90% confidence interval and 43 degrees of freedom is t=1.681.

Now, Margin of error = 2.261* 1.681 = 4.4059

Now, the lower and upper bound of the confidence interval are:

LL = 3.3- 4.40459 = -1.1059

UL = 3.3+ 4.40459 = 7.70459

Hence, the confidence interval is  (-1.1059, 7.70459).

There are chocolates in a box, all identically shaped. There are 8 filled with nuts, 16 with caramel, and 14 are solid chocolate. You randomly select one piece, eat it, and then select a second piece. Find the probability of selecting 2 solid chocolates in a row.

Answers

Answer:

P = [tex]\frac{91}{703}[/tex] ≅ 12.95%.

Step-by-step explanation:

The total amount of chocolates in the box is 8 + 16 + 14 = 38, 14 of which are solid.

Let's calculate the probability of getting a solid chocolate in the first selection:

[tex]P(1S) = \frac{14}{38} = \frac{7}{19}.[/tex]

Given that the first piece was solid, there are now 37 pieces of chocolate in the box, 13 of which are solid. Let's now calculate the probability of selecting another solid chocolate:

[tex]P(2S\,|\,1S) = \frac{13}{37}.[/tex]

Thus, the probability of selecting two solid chocolates in a row is the product of the two probabilities calculated above:

[tex]P = \frac{7}{19}\,.\,\frac{13}{37} = \frac{91}{703}.[/tex]
