Answer:
<em>Option D</em>
Step-by-step explanation:
Assume that these polygons were similar. You could tell that if they were, ABCD ~ EFGH, and is already noted by the answer choices. We can conclude that AB ~ EF, CD ~ GH and so on. To prove that these shapes are similar, we must form a like proportionality among these side;
As the proportions we formed were to equal to one another,<em> the solution must be option D!</em>
Answer:
-46.91%
Step-by-step explanation:
Given:
Cost of buying the shares = $53,500
Selling cost of the shares = $3,300
Number of years = 2
Since the selling cost is less than the buying cost, therefore the statement for the loss can be verified
Now,
The loss = Selling cost - cost of buying = $3,300 - $53,500 = - $50,200
thus, the loss per year = = -$25100
Hence,
Rate of return =
or
Rate of return =
or
Rate of return = -46.91%
The equations and inequality expresses the relationship between the variables.
The correct responses are;
- First part; The rule that represent the function is; <u>y = 0.5·x - 1</u>
- Second part; the correct option is the inequality; <u>2·n - 6 ≥ 35</u>
- Third part;
- Fourth part; <u>Table 4</u>
- Fifth part;
- Sixth part; <u>75·w + 55 ≤ 400</u>
Reasons:
First part;
The difference between y-values following a change in 2 units of the x-value is a constant, and is equal to 1;
The rate of change of the function, <em>m</em>, is therefore;
The slope and intercept form of the equation of the function is therefore;
y - 3 = 0.5·(x - 8) = 0.5·x - 4
y = 0.5·x - 4 + 3 = 0.5·x - 1
The rule that represent the function is; <u>y = 0.5·x - 1</u>
Second part;
2·n represent twice the number
The difference between twice the number and 6 = 2·n - 6
At least 35 = ≥ 35
Therefore, the inequality is; <u>2·n - 6 ≥ 35</u>
Third part;
The given quadratic equation is; a·x² + b·x + c = 0
Therefore;
Fourth part;
The best correct option is table 4, given that the table is as follows;
Fifth part;
The y-intercept of the graph is -0.5
The slope is -4 ÷ 8 = -0.5
Therefore, the equation is; y = -0.5·x - 4
The shaded area is the area lower than the y-values, with broken lines (indicating < relationship) which gives, the correct inequality as follows;
Sixth part;
The amount Jordan part-time job pays = $75
The amount he has already saved = $55
The cost of the iPhone = $400
Let <em>w</em> represent the number of weeks Jordan works, at his part-time job to purchase the iPhone, we have;
<u>75·w + 55 ≤ 400</u>
