Step-by-step explanation:
For the left end of the function, it moves up towards positive infinity.
For the right end of the function, it movea down towarda negative infinity.
Therefore as x approaches -infinity, y approaches +infinity and as x approaches +infinity, y approaches negative infinity. (2nd option)
What is the answer to this
Answer:
x = - 1
Step-by-step explanation:
Given
- 5x - 16 = 9x + x - 1, that is
- 5x - 16 = 10x - 1 ( subtract 10x from both sides )
- 15x - 16 = - 1 ( add 16 to both sides )
- 15x = 15 ( divide both sides by - 15 )
x = - 1

Value of x in the rhombus is [tex]28^{0}[/tex].
What is rhombus?A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square.
According to the question
DB, CA are diagonal line
So, <CAB + <DBA = [tex]90^{0}[/tex]
⇒ x + 6 + 2x = [tex]90^{0}[/tex]
⇒ 3x = 90 - 6
⇒ 3x = 84
⇒ x = [tex]\frac{84}{3}[/tex]
⇒ x = [tex]28^{0}[/tex]
Hence, value of x in the rhombus is [tex]28^{0}[/tex].
Find out more information about rhombus is [tex]28^{0}[/tex].

Step-by-step explanation:
y = 230x + 100
Is this proportional or non proportional?
Proportional equations are of the form y = kx, for some fixed constant k. The k value is the constant of proportionality.
The +100 at the end is why we don't have a proportional equation.
Visually all proportional equations go through the origin, meaning the lines have y intercept of 0. For y = 230x+100, the y intercept is 100.

A) Greater than 0.2
B) Between 0.19 and 0.10
C) Between 0.09 and .05
D) Between .049 and .02
E) Less than 0.02
Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The mean of sample 1 is [tex]\= x_1 = 10[/tex]
The standard deviation is [tex]s_1 = 6[/tex]
The mean of sample two is [tex]\= x_2 = 16[/tex]
The standard deviation is [tex]s_2= 4[/tex]
The sample size for both samples is [tex]n_1 = n_2 = n = 6[/tex]
The null hypothesis is [tex]H_o : \mu_1 = \mu_2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 \ne \mu_2[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{ \= x_1 - \= x_2 }{ \sqrt{ \frac{s^2_1}{n_1} +\frac{s^2_1}{n_2} } }[/tex]
=> [tex]z = \frac{ 10 - 16 }{ \sqrt{ \frac{6^2}{6} +\frac{4^2}{6} } }[/tex]
=> [tex]z = -1.3646[/tex]
From the z table the area under the normal curve to the left corresponding to -1.3646 is
[tex]P(Z < -1.3646) = 0.086189[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 P(Z < -1.3646)[/tex]
=> [tex]p-value = 0.086189 * 2[/tex]
=> [tex]p-value = 0.1724[/tex]
So the p-value is Between 0.19 and 0.10

Saturday, $690 was collected in sitting fees. Which
equation can be used to represent x, the number of
three-pose portrait packages, and y, the number of
six-pose portrait packages?
A. 360x + 105y = 690
B. 35x + 60y = 690
C. 60x + 35y = 690
D. 105x + 360y = -690
Answer:
35x + 60y = 690
Why:
We need to correct number to represent X (which is 35) and Y (which is 60).
And 35x + 60y = 690, 690 being the total, fits what we need to answer.
All of the other options display an incorrect number for the X and Y values.
Answer:
35x + 60y = 690

f(x)=4(0.5)^-1
Find the y value
Answer: y = 0.5x - 4
Step-by-step explanation:
Answer:
y=8
Step-by-step explanation:
In functions, you should know that f(x)=y. In this problem, y is replaced by 4(0.5)^-1. So all you need to do is solve what 4(0.5)^-1 is, which is 8. This means that f(x)=8, but y is also equal to f(x). The answer is then y=8.

Consider the factors of the constant term (+ 78) whuch sum to give the coefficient of the x- term (+ 19)
The factors are + 6 and + 13 , since

x² + 19x + 78 = (x + 6)(x + 13) ← in factored form

the average of nadine's six test is 77. The scores on the five of the test are 88,65,75,83 and 90. what is the score on the remaining test?
A. 91
B. 81
C. 71
D. 61
Answer:
The score on the remaining test is x = 61
Hence, option D is correct.
Step-by-step explanation:
Let 'x' be the score of the remaining test
The average score of Nadine's six tests = 77
so
Average score = (88+65+75+83+90+x) / 6
substituting average score = 77 in the equation to find 'x'
77 = (401 + x) / 6
401 + x = 77 × 6
x = 462 - 401
x = 61
Therefore, the score on the remaining test is x = 61
Hence, option D is correct.

6. Determine the number of solutions for each of the equations below. Be sure to
justify your conclusions. *
(z – 8)2 = -1
A. one solution
B. infinitely many solutions
C.no solution
D. x = 9
Answer:
C. no solutionStep-by-step explanation:
Determine the number of solutions for each of the equations below. Be sure to
justify your conclusions. *
(z – 8)2 = -1
A. one solution
B. infinitely many solutions
C.no solution
D. x = 9
Given the expression;
(z – 8)^2 = -1
we are to find the nature of the solution;
Take the square root of both sides
(z – 8)^2 = -1
√(z – 8)^2 = √-1
z- 8 = √-1
Note that √-1 will give a complex number i to have;
z = 8 ± i
This therefore shows that the equation has no real solution.
Find the x and y intercepts of the following equation. 3x - 8y = 24
Write the equation of the line in fully simplified slope-intercept form.
Step-by-step explanation:
For every 3 squares across, the line drops by 1 square.
Therefore the slope of the lina is -1/3.
The y-intercept of the line is -8 (when x = 0)
The equation of the line is y = -1/3 x - 8.

Aaron rolled a fair six-sided number cube, numbered 1 through 6, several times and recorded the data in the table below. Which statement about this situation is true? *
Answer:
Aaron rolled a fair six-sided number cube, numbered 1 through 6 is explained below in details.
Step-by-step explanation:
a. FALSE
Trial possibility of rolling a 6 =1/20 = 0.05
Logical possibility of rolling a 6 = 1/6 = 0.17(approximately.)
So the trial possibility of rolling a 6 is not equal to the logical possibility of rolling a 6.
b. FALSE
Trial possibility of rolling an even number = Trial possibility of rolling number 2,4 or 6 = 4/20+2/20+1/20= 7/20 = 0.35
Logical possibility of rolling an even number = 3/6 = 1/2=0.5
Therefore the Test possibility of rolling an even number is shorter than the logical possibility of the same.
c. TRUE
Trial possibility of rolling a 1= 6/20= 0.3
Logical possibility of rolling a 1= 1/6 = 0.17 (approx.)
So the Trial possibility of rolling a 1 is greater than the logical possibility of rolling a 1.
d. FALSE.
Trial possibility of rolling a 4= 2/20= 0.1
Logical possibility of rolling a 4 = 1/6 = 0.17 (approx.)
So the Trial possibility of rolling a 4 is less than the logical possibility of rolling a 4.

Answer:
Step-by-step explanation:
abc=80, abm= 100
acb= 40, acn= 140
angle a = 60
x=80, y=40
Answer:
x = 80° y = 40°
Step-by-step explanation:
ABC = 80° ACB = 40°
ABC+ACB+A = 180° (sum of angles in a triangle = 180°)
80+40+A = 180°
A = 60° (sum of angles in a triangle = 180°)
X = 80° (ALTERNATE ANGLES, angles x is alternate to angle ABC = 80° )
y = 40° (alternate angles, angle y is alternate to angle ACB = 40°)
to cross-check : sum of angles on a straight line = 180°
x+ y + A = 180sum of angles on a straight line = 180°
80+40+60 = 180°
ABM = 100° = (sum of angles on a straight line = 180°)
80° + 100° = 180°
ACN = 140° (sum of angles on a straight line = 180°)
40° + 140° = 180°

Answer:
Question 2: √x
Question 5: B and D
Step-by-step explanation:
If you move a factor from the denominator to the numberator (or vice versa) its exponent must flip sign.
I.e., [tex]\frac{1}{x^{-1}}[/tex] will become [tex]\frac{x^1}{1}}[/tex] which is x
Multiplying the same number x you must add the exponents. (1/3)+(1/3)+(1/3) is 1, so D is also x¹.
Therefore B and D are equivalent.

The length of a box as reported by its manufacturer is 13.67 cm. Joe has a ruler which has markings for each millimeter. Which most likely represents the length of the box that Joe is able to measure?
Answer:
Option (3)
Step-by-step explanation:
Joe has a ruler which has markings for each millimeter, so the least measurement which Joe can do is in millimeter.
Since, 10 mm = 1 cm
Therefore, 1 mm = 0.1 cm
This rule states that Joe can measure a length or distance in nearest tenth of a cm only.
If length of a box = 13.67 cm,
So Joe can measure it as 13.7 cm approximately.
Therefore, Option (3) will be the answer.
