work out the equation of the line which has a gradient of 2 and passes through the point (1, 4)
Answer:
y = 2x + 2
Step-by-step explanation:
The slope is also called the gradient of the line.
The slope that is given is two, and the point is (1, 4).
I made a point slope equation, and then converted it into a slope-intercept equation.
[tex]y-4=2(x-1)\\\\y-4=2x-2\\\\y-4+4=2x-2+4\\\\\boxed{y=2x+2}[/tex]

A f(x) = x2 - 8x+15
B. f(x) = x2 -15x-8
C. $(x) = x? - 8x-15
which is the equivalent?
Answer:
Step-by-step explanation:

The measures of the angles of a triangle are in a ratio 2/3 / 5 . What are the measures of the angles?
Answer:
36°, 54°, 90°
Step-by-step explanation:
2:3:5 equal 10 parts in total
there are a total of 180 degrees in a triangle
180°/10 = 18°
2(18°) = 36°
3(18°) = 54°
5(18°) = 90°

g(x) = 2
g(x) = -
O A. g(x) = (x - 4)2 + 1
O B. g(x) = (x+4)2 - 1
O c. g(x) = (x - 4)2 - 1
O D. g(x) = (x+4)2 + 1
Answer:
If the attached graph is the one you mean, the answer is g(x) = (x-4)^2 + 1
The equation of the blue graph is,
⇒ g (x) = (x - 4)² + 1
Given that;
The given function is,
⇒ f (x) = x²
Since, It is given that both graph has same shape it means the equation of blue graph is in the form of;
⇒ g (x) = (x - h)² + k
Where, (h,k) is the vertex of the parabola.
Hence, From the given graph it is noticed that vertex of blue parabola is (4,1),
Therefore, the equation of parabola is,
⇒ g (x) = (x - 4)² + 1
Thus, The equation of the blue graph is,
⇒ g (x) = (x - 4)² + 1

Write an explicit formula for an, the nth term of the sequence 35, 38, 41, ...
Answer:
[tex]a_{n}[/tex] = 3n + 32
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 38 - 35 = 41 - 38 = 3
This indicates the sequence is arithmetic with n th term ( explicit formula )
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 35 and d = 3 , then
[tex]a_{n}[/tex] = 35 + 3(n - 1) = 35 + 3n - 3 = 3n + 32
Estimate 12% of 77?
Answer: 9.24
Step-by-step explanation:
12*77 = 924
= 9.24
The answer to the given question is estimating 12% (percent) of 77, we get the answer 9.24.
To calculate 12% of 77 precisely, we can use the following formula: percent / 100 × given number
= 12% of 77
= (12/100) × 77
= 9.24
Therefore, 12% of 77 is 9.24.A percentage is a way of expressing a number as a fraction of 100. The symbol "%" is used to is used to indicate a percentage. For example, if we say that something is 25%, we mean that it is 25 out of 100 or 0.25 as a decimal. Percentages are used in many different areas, such as finance, statistics, and science. They can be used to represent proportions, rates of change, or as a way to compare different quantities. One common use of percentages is to calculate percentage change or increase. This is done by finding the difference between two values and expressing it as a percentage of the original value.

Please i need help fast! Which of the following sets of numbers could not represent the three sides of a triangle?
Answer:
{7, 21, 28}
Step-by-step explanation:
In order for three sides to add up to a triangle, the two shorter sides must have a sum of greater than the longest side.
Since 7 + 21 = 28, and 28 = 28, that group of sides cannot add up to be a triangle.

a student wrote a proof about the product of two rational numbers:
Let x = a/b and let y = c/d, where a and c are defined to be integers, and b and d are nonzero integers.
By substitution, xy = ac/bd.
By applying the closure property of integers and nonzero integers on multiplication, ac is an integer and bd is a nonzero integer.
What conclusion can the student now make about the product xy?
A- the product xy is a nonzero Integer because nonzero Integers are closed on division.
B- the product xy cannot be an integer because bd is a nonzero Integer.
C- the product xy may be elther rational or Irrational because the values of a, b, c, and d are unknown.
D- the product ry is rational because it can be written as the quotient of an Integer and a nonzero Integer.
A rational number is a number that can be expressed as a fraction of integers.
The conclusion the student can make about product xy is that:
D- the product ry is rational because it can be written as the quotient of an Integer and a nonzero Integer.
Given that:
[tex]x = \frac ab[/tex]
[tex]y = \frac cd[/tex]
The product xy is:
[tex]x \times y = \frac ab \times \frac cd[/tex]
So, we have:
[tex]x \times y = \frac{ac}{bd}[/tex]
From the question, we understand that:
[tex]Integers \to a, c[/tex]
This means that, ac would be an integer (by closure property)
Also:
[tex]Non\ zero \to b,d[/tex]
This means that, bd would be non-zero i.e. [tex]bd \ne 0[/tex]
So, we have:
[tex]x \times y = \frac{ac}{bd}[/tex]
[tex]x \times y = \frac{Integer}{Non\ zero}[/tex]
The quotient of an integer and a non-zero integer is always be rational.
Hence, option (d) is correct.
