2. A line with slope passes through the point (1,3
a. Explain why (3, 6) is on this line.
b. Explain why (0, 0) is not on this line.
Answer:
Step-by-step explanation:
If a line with a slope passes through a point with a value such as in this one, which is (1,3), then it must have a y-intercept and a slope. The y-intercept is when the x-value's value is 0 but the y-value is more than 0.
(3,6) is on the line as it corresponds with the slope.
(0,0) is not on this line as the y-value nor the x-value has a coordinate, which is a requirement to make it an ordered pair.

While you're in the parking lot, you realize that both the lightbulbs and the light switches
need to be replaced. You buy 9 bulbs and 4 switches. Each light switch cost $8 less than
each lightbulb. If the total cost is $520.50, what is the cost of one lightbulb? What is the cost
of one light switch? Write an equation for the situation.
Let x = the cost of a lightbulb
Cost of Lightbulb = x
cost of switch is x-8
9x + 4(x-8) = 520.50
Use distributive property:
9x + 4x -32 = 520.50
Simplify:
13x -32 = 520.50
Add 32 to both sides:
13x = 552.50
Divide both sides by 13
X = 42.50
A lightbulb costs $42.50
A switch costs 42.50-8 = $34.50

Answer:
The area of figure = 600 cm ²
Step-by-step explanation:
Area of this figure = area of triangle + area of rectangle
Area of triangle = 1/2 × base × height
Area of rectangle = length× breadth
=> (1/2 × 20 × 20 ) + ( 20×20 )
=> 200 + 400
=> 600 cm²

T(x, y) = (x-6, y + 5)
P' = ([?], [])

Answer:
P' (- 3, 1 )
Step-by-step explanation:
the translation
(x, y ) → (x - 6, y + 5 )
means subtract 6 from the x- coordinate and add 5 to the y- coordinate, so
P (3, - 4 ) → P' (3 - 6, - 4 + 5 ) → P' (- 3, 1 )

The value of y is directly proportional to the value of x. If y=2/3 whenx=1/12 , what is the value of y when x = 1/2 ?
Step-by-step explanation:
Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX
"K" is the constant of proportionality and must be determined from the initial information.
If Y = 2/3 when X=1/12means 2/3=1/12
K = 2/3÷1/12 = 8
Now that we know the value of K, we can use it to calculate the value of Y when X=1/2
Y = (8)(1/2) = 8/2=4
Y=4

If one leg of a right triangle is 18 units and the other leg is 24 units, what is the length of the hypotenuse (in units)?
In response to the supplied query, we may state that Therefore, the Pythagorean theorem length of the hypotenuse is 30 units.
what is Pythagorean theorem?The Pythagorean Theorem, often known as the Pythagorean Theorem, is the fundamental Euclidean geometry relationship between the three sides of a right triangle. The area of a square with the hypotenuse side equals the sum of the areas of squares with the other two sides, according to this rule. The Pythagorean Theorem says that the square that spans a right triangle's hypotenuse opposite the right angle equals the sum of the squares that span its sides. It is sometimes written as the general algebraic notation a2 + b2 = c2.
The Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two legs (the sides that create the right angle) is equal to the square of the length of the hypotenuse, may be used to determine the length of the hypotenuse (the side opposite the right angle).
In this instance, we have two legs, one measuring 18 units and the other 24 units. Let's call the hypotenuse's length "c" for short. The Pythagorean theorem may then be used to determine the value of "c":
[tex]c^2 = 18^2 + 24^2\\c^2 = 324 + 576\\c^2 = 900\\c = \sqrt(900)\\c = 30[/tex]
Therefore, the length of the hypotenuse is 30 units.

A force of 61 N is applied to an area of 750 cm2. Calculate the pressure in N/m2. Give your answer to the nearest integer
Answer:
813 N/m²
Step-by-step explanation:
The units of pressure tell you it is found by dividing force by area. Here, we need to convert the units of the given area so we can express the pressure appropriately.
__
pressure = force / area
pressure = (61 N)/(750 cm² × ((1 m)/(100 cm))²) = (61 N)/(0.0750 m²)
pressure ≈ 813 N/m²

Nick has 5, 10, 20, 50 cent coin in his pocket.
He accidentally takes 2 coins out of his pocket. Calculate the possibility of the sum of the two coins that he has taken out being 25 cents.
Answer:
possibility is 1 in 6
Step-by-step explanation:
combinations of 2 coins are
5/10 , 5/20 , 5/50 → 3 possibles
10/20 , 10/50 → 2 possibles
20/50 → 1 possible
there are 6 possible combinations of the 2 coins
the only possible combination for 25 cents is 5/20
thus the possibilty of 2 coins summing to 25 cents is 1 in 6
Dorothy works 40 hours per week. Her salary is $3,624.34. After deductions her pay is $2,718.26.
What is the net income?
The net income of Dorothy when she works 40 hours per week and her net pay is $2,718 monthly (4 week) is $17/ hour approximately.
How to interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, [tex]a \div b = a[/tex] divided in b equal parts.
Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]
(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex])
For this case, we're given that:
Dorothy works 40 hours per weekThe final salary she gets after deduction is $2,718.26 (assuming this is monthly based salary, and each month having equal 4 weeks).Since there are 4 weeks in a month, and each week, Dorothy works 40 hours per week, so the number of hours she worked in those 4 weeks (one month work approx) is:
[tex]40+40+40+40 = 4 \times 40 = 160 \: \rm hours[/tex]
That means, Dorothy gets $2718.26 for 160 hours of work.
Thus, if we divide this salary in 160 parts equally, we'll get net hourly income of Dorothy, as shown below:
[tex]\text{1 hour's pay} = \dfrac{2718.26}{160}\approx 16.98 \approx 17 \: \rm dollars[/tex]
Thus, the net income of Dorothy when she works 40 hours per week and her net pay is $2,718 monthly (4 week) is $17/ hour approximately.
