f(x)=2/3x−1 and g(x)=−4x+6. What transformation occurs from function f to function g?
Answer:
vertically stretched by multiplying each of its y-coordinates by 6, and is followed by a reflection across the x-axis.
Step-by-step explanation:
[tex]f(x)=\dfrac{2}{3}x-1\qquad|\text{multiply both sides by (-6)}\\\\-6f(x)=-6\cdot\dfrac{2}{3}+(-6)(-1)\\\\-6f(x)=-4x+6\\\\-6f(x)=-(4x-6)[/tex]

Answer:
Such triangles do not exist.Step-by-step explanation:
There is some mistake in your question.
We know:
In any triangle with sides a, b and c:
a + b > c
a + c > b
b + c > a
In your question the triangle ABC has:
a = 5, b = 10, c = 15
then
5 + 10 = 15 not > 15.
a + b = c not > c.
In my opinion, the question makes no mathematical sense.
Nevertheless, the moderator asked me to correct my answer.
If two triangles are similar, then corresponding sides are in proportion.
[tex]\dfrac{10}{5}=\dfrac{20}{10}=\dfrac{x}{15}\\\\2=2=\dfrac{x}{15}\\\\\dfrac{x}{15}=2\Rightarrow x=30[/tex]

Nina is selling three types of energy bars at a market stall.
She bought 80 Enerbars at 40p per bar and 180 Grainbars at 30p per bar from her normal supplier.
She was also given 40 Amazebars as a promotion from a new supplier.
Nina sells the bars for £2.25 and manages to sell all the Enerbars and Grainbars but only some Amazebars.
She makes a profit of £553.
How many Amazebars did she sell?
Answer:
She sold 24 Amazebars.
Step-by-step explanation:
Cost:
80 x 0.40 = 32
180x 0.30 = 54
40 x 0 = 0
Total = 86
Income
80 x 2.25 = 180
180 x 2.25 = 405
X x 2.25 = 2.25x
Total = 585 + 2.25x
How many did she sell:
553 = 585 - 86 + 2.25x
553 = 499 + 2.25x
553 - 499 = 2.25x
54 = 2.25x
54/2.25 = x
24 = x

1. Given f(x)=4x+1 and g(x)=4(x+3)+1, describe how the graph of g compares with the graph of f.
A) The graph of g is shifted right 3 units from the graph of f
B) The graph of g is shifted down 3 units from the graph of f.
C) The graph of g is shifted up 3 units from the graph of f.
D) The graph of g is shifted left 3 units from the graph of f.
2. Given f(x)=4x+1, describe how setting = affects the slope and y‑intercept of the graph of g(x)=4(x+1)+3 compared to the graph of f
A) The slope of g is scaled by a factor of 4 from that of f, and the y‑intercept is not changed.
B) The slope of g gets steeper, and the y‑intercept is not changed.
D) The line of function g gets closer to the y-axis, and the y‑intercept is not changed.
C) All of the above.
Answer:
AB
Step-by-step explanation:
The graph of g is shifted left 3 units from the graph of f and 12 units up. Therefore, option D is the correct answer.
The given functions are f(x)=4x+1 and g(x)=4(x+3)+1.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Shifted up: 12 units
The graph of g is shifted left 3 units from the graph of f and 12 units up. Therefore, option D is the correct answer.
