The graph of the inequality is graph (B)
How to determine the graphThe inequality is given as:
[tex]5 + 8x < 3(2x + 4)[/tex]
Start by expanding the bracket
[tex]5 + 8x < 6x + 12[/tex]
Next, we collect the like terms
[tex]8x - 6x < 12 - 5[/tex]
Evaluate the like terms
[tex]2x < 7[/tex]
Solve for x
[tex]x < 3.5[/tex]
The above means that, the values of x are less than 3.5
Hence, the inequality is graph (B)

6. The cost C of hiring a taxi is given by the formula C = 4 + 1.25m where m is the number of miles driven. Make a table showing the cost of hiring the taxi to drive 1, 2,3, and 4 s, Dete whether the cost of the taxi is proportional to the number of miles driven. Explain your reasoning.
Answers
The ratios are not all equal, we can conclude that the cost of the taxi is not proportional to the number of miles driven.
What is proportional?
A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4)
To find the cost of hiring a taxi to drive 1, 2, 3, and 4 miles, we can use the formula:
C = 4 + 1.25m
For m = 1, we have:
C = 4 + 1.25(1) = 5.25
For m = 2, we have:
C = 4 + 1.25(2) = 6.5
For m = 3, we have:
C = 4 + 1.25(3) = 7.75
For m = 4, we have:
C = 4 + 1.25(4) = 9
So the table of costs for driving 1, 2, 3, and 4 miles is:
Miles (m) Cost (C)
1 5.25
2 6.5
3 7.75
4 9
To determine whether the cost of the taxi is proportional to the number of miles driven, we can check whether the ratios of cost to distance are equal. If they are, then the cost is proportional to the number of miles driven.
Let's check the ratios:
C(1)/1 = 5.25/1 = 5.25
C(2)/2 = 6.5/2 = 3.25
C(3)/3 = 7.75/3 = 2.58333...
C(4)/4 = 9/4 = 2.25
Hence, the ratios are not all equal, we can conclude that the cost of the taxi is not proportional to the number of miles driven.

Step-by-step explanation:
a.We can define h and w to represent the height in inches and the weight in pounds. Then the inequalities representing the given restrictions are ...
h < 79 . . . . . . . . height is less than 6'7"
w < 295 . . . . . . weight is less than 295 pounds
The graph is attached. The solution space is the area where the solutions to the inequalities overlap.

(h, w) = (60, 280) . . . . is a possible solution

c.(50, 180) is a solution. The height of 50 inches is less than 79 inches, and the weight of 180 pounds is less than 295 pounds. (A person with these measurements would be quite obese.)

As a practical matter, healthy 18-year-olds will generally have a height greater than 59 inches and a weight greater than 95 pounds. Less than 3% of the population will be shorter or lighter than that.
"Good physical condition" may require a body mass index within a certain range. This will put additional (rather narrow) limits on height and weight. We have only shown inequalities and a graph for the specific conditions listed in the problem statement.

4) a₈ = 66
5) a) 138
b) 55
c) [tex]a_n=55n+83[/tex]
Step-by-step explanation:
Question 3
The common difference of an arithmetic sequence is the difference between consecutive terms.
Therefore, to find the common difference, subtract one term from the next:
⇒ d = 5 - 3.2
⇒ d = 1.8
Question 4
Given arithmetic sequence: [tex]a_n=10n-14[/tex]
To find the 8th term, substitute n = 8 into the equation:
[tex]\implies a_8=10(8)-14[/tex]
[tex]\implies a_8=80-14[/tex]
[tex]\implies a_8=66[/tex]

In the given figure find the value of the unknown interior angle x in the following figure.
Answers
Answer:
Therefore, the measure of angles x is 70°.
Step-by-step explanation:
From the given figure ,
115° is the exterior angle
x° and 45° are the two interior opposite angles to 115°
We know that
An exterior angle formed by extending the side of a triangle is equal to the sum of the two interior opposite angles
⇛ x° + 45° = 115°
⇛ x° = 115°-45°
⇛ x° = 70°
Therefore , x = 70°

The slope of the line parallel to the given line is 1.
What is slope?Slope is a value that describes the steepness and direction of a line. In variable format, it is commonly represented by the letter m.
The slope of a line is also called its gradient or rate of change. The slope formula is the vertical change in y divided by the horizontal change in x, sometimes called rise over run.
Given that the equation of a line y - x = 5, we need to find the slope of the parallel to the same,
Converting the equation in slope-intercept form,
y - x = 5
y = x + 5
Comparing with standard form of the equation of the line y = mx + c, where m is the slope,
Hence, the slope of the given line is 1,
We know that the slopes of the parallel lines are equal.
So, the slope of the asked line is 1.
Hence, the slope of the line parallel to the given line is 1.

Answers
We know that 9/20 dogs are spaniels, so 11/20 of the dogs will not be spaniels. That would be your probability in fraction form, but if you need percentage, remember that you can find percentage of something by multiplying the fraction by 100 and evaluating, so [tex](\frac{11}{20} )*100= 0.55*100= 55[/tex]. So, the percentage of dogs that are not spaniels would be 55%.

The given parameters are:

So, the probability that the next person tells the truth is:
