10. The graph of a linear function that passes through the points (-2, 1) and (8, 6) is shown.
Y
What is the y-intercept of the graph of the linear function?
Answers
Answer:
(0,2)
This is extra, but the function would be y = 0.5x + 2.
Step-by-step explanation:
The y-intercept is simply where the function intersects the y-axis. In this, case it's intersecting at (0,2) so that is the answer.
To find the equation for this:
y2 - y1/x2 - x1
6 - 1/8 - (-2)
6 - 1/8 + 2
5/10 = 0.5
y = 0.5x + b
6 = 0.5(8) + b
6 = 4 + b
6-4 = (4-4) + b
2 = b
With that, the equation becomes y = 0.5x + 2

Jackson has to have his car repaired. The mechanic tells him it will cost $75 for each hour of labor plus the cost of the parts. He discovers that the parts cost $165.
Part A: Write an equation that can be used to determine the cost of the repairs for any hours of labor.
Part B: How much would the repairs be if it took 3 hours?
Part C: What is the meaning of the slope in Part A?
Part D: What is the meaning of the y-intercept in Part A?
Answers
Answer:
a 75x+165=y
b 75(3)+165=390
c 75x is the cost increasing for each hour
d y-intercept=165, it cost at least 165 for the parts

solve (x^2+3x-2)(x^2-2x+15)
Answers
Answer: x^4 + x^3 + 7x^2 + 49x - 30
Step-by-step explanation:
first, we use the distributive property.
x^2 x (x^2 - 2x + 15) + 3x x (x^2 -2x + 15) - 2(x^2 - 2x + 15)
then, we remove the parenthesis.
x^4 - 2x^3 + 15x^2 + 3x^3 - 6x^2 + 45x - 2x^2 + 4x - 30
then, we collect like terms.
x^4 + x^3 + 7x^2 + 49x - 30

Sean multiplied two numbers and the resulting product was an irrational number. If the first number was 7/3, which of the following could be the second number? Two apply. 3/7, 2pie, 1, square root of three
Answers
Answer: 2*pi and √3.
Step-by-step explanation:
We know that when we multiply a rational number different than zero and an irrational number, the product will be also an irrational number.
Then if one of the numbers for this case is 7/3 (A rational number), the other must be an irrational number.
The given options are:
3/7 (is a rational number, so this is not the correct option)
2*pi (pi is an irrational number, then 2*pi is also an irrational number)
Then (2*pi)*3/7 will be an irrational number.
1 (this is a rational number, then this is not the correct option)
√3 (This is an irrational number, then this will be a correct option)
Then the two correct options are:
2*pi and √3.

Five less than twice the value of a number is equal to three times the quantity of four more than one-half the number. What is the number?
Answers
Answer:
2x - 5 = (1/2)
4x - 10 [multiply by 2]
x - 10 = -13 [subtract 3x from both sides]
x = -3 [add 10 to both sides]
Step-by-step explanation:
The required number would be 34 which is determined by the phrase "five less than twice the value of a number is equal to three times the quantity of four more than one-half the number"
What is algebra?Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.
When broken down, these sorts of statements are not intimidating. First, consider "five less than twice the value of a number."
"Twice the value of a number" is simply 2x.
"Five less" is simply -5, so for the first part we have (2x-5)
Examine the second section next. "Three times four times more than one half the number."
"Three times the quantity" simply indicates "three times something."
4 + "one half the number" or 4 + (1/2)x is "the quantity of four more than one half the number."
So the second part is simply 3(4+x/2).
Finally, we complete the equation, (2x-5) = 3(4+x/2) and solve for x.
2x-5 = 12 + (3/2)x
2x-(3/2)x = 17
x/2 = 17
x = 34
Therefore, the required number would be 34.

First, we need to find the original ratio of 7th to 6th
6th = 12
7th = 21
21:12
Then find any common factors
21: 1,3,7,21
12: 1,2,3,4,6,12
divide 21 and 12 both by 3
21/ 3 = 7
12 / 3 = 4
7:4 is your ratio

Josh was packing to move to another office. He packed 3 2/5 boxes on Tuesday and 2 9/10 boxes on Wednesday. After everything was moved to his new office on Wednesday afternoon, he only found 4 1/4 boxes. How many boxes were missing?
Answers
Answer:
2 1/10 boxes were missing.
Step-by-step explanation:
It is given that,
Josh packed [tex]3\dfrac{2}{5}[/tex] boxes on Tuesday
Josh packed [tex]2\dfrac{9}{10}[/tex] boxes on Wednesday
After everything was moved to his new office on Wednesday afternoon, he only found [tex]4\dfrac{1}{4}[/tex] boxes.
We need to find the no of boxes that are missing.
Total no of boxes packed on Tuesday and Wednesday,
[tex]3\dfrac{2}{5}+2\dfrac{9}{10}\\\\=\dfrac{17}{5}+\dfrac{29}{10}\\\\=\dfrac{63}{10}[/tex]
Missing boxes :
[tex]M=\dfrac{17}{4}-\dfrac{63}{10}\\\\=\dfrac{41}{20}\\\\=2\dfrac{1}{20}[/tex]
Hence, 2 1/10 boxes were missing.
