A line has a slope of 3 and passes through the point (8, 261. What is the
equation of the line?
Answer:
Step-by-step explanation:
We know that the form of line passing through point (x₀ , y₀) and having slope m is :
y - y₀ = m(x - x₀)
Here the line passes through the point (5 , -3)
⇒ x₀ = -2 and y₀ = -5
Given : Slope(m) = -8
Substituting all the values in the standard form, We get :
Equation of the line : y + 3 = -8(x - 5)

There are fewer than 30 students in the A-level mathematics class. One half of them
play the piano, one quarter play hockey and one seventh are in the school play.
How many of the students play hockey?
The number of students that play hockey is 7
The proportion is given as:
[tex]Piano =\frac 12[/tex]
[tex]Hockey =\frac 14[/tex]
[tex]School\ Play =\frac 17[/tex]
The total number of students must be a multiple of 2, 4 and 7 less than 30;
The only multiple of 2, 4 and 7 less than 30 is 28.
The number of students that play hockey is the product of 28 and the proportion that plays hockey.
So, we have:
[tex]Hockey =\frac 14 \times 28\\[/tex]
Multiply
[tex]Hockey =7[/tex]
Hence, 7 students play hockey

at the first blank there are options either (y-intercept, slope, x-intercept)
second blank (positive, negative, 0, a whole number)
Answer:
y-intercept
zero
Step-by-step explanation:
We can determine the differences between proportional and non-proportional situations or relationships. We all need to know that linear relationships can be represented as tables, words, equations, and graphs. The non-proportional relationship will affect the y-intercept in the graph and it will no longer than zero and the ratios in the table not be proportional.

is the expression x³·x³·x³ equivalent to x³·³·³? why or why not? explain your reasoning
Answer:
Definitely not equivalent.
Exponent rules state that whenever you multiply terms with the same power, you add the powers together and multiply the coefficients.
x^3*3*3 is equivalent to something like ((x^3)^3)^3 or x^27
x^3 * x^3 * x^3 would be x^3+3+3 or x^9

you need to prepare 50 portions of broccoli flowers. A prepared portion weighs 0.090kg. Trimmings account for 25% of the total weight. How much broccoli do you need to order ?
The amount of broccoli needed to be ordered to prepare 50 portion of broccoli flower is 3.375 kg.
You need to prepare 50 portions of broccoli flowers.
A prepared portion weighs 0.090 kg.
Trimming accounts for 25% of the total weight.
Therefore, to find how much broccoli is needed to order can be calculated as follows:
Trimming account for 25% of 0.090 = 0.0225 kg The remaining weight(broccoli) required = 0.090 - 0.0225 = 0.0675 kgTherefore,
the broccoli needed to be ordered = 0.0675 × 50 = 3.375 kg

What are the steps to convert a number from standard notation to scientific notation
Answer:
Step-by-step explanation:
Let's take 4200 as an example.
To convert 4200 into scientific notation, follow these steps:
- Move the decimal 3 times to left in the number so that the resulting number, m = 4.2, is greater than or equal to 1 but less than 10
- Since we moved the decimal to the left the exponent n is positive
n = 3
- Write in the scientific notation form, m × 10^n
= 4.2 × 10^3
Therefore, the decimal number 4200 written in scientific notation is 4.2 × 10^3 and it has 2 significant figures.
