Which transformations of the graph of 1x) = -4*x result in the graph of f(x) = 4x+3?

Mathematics

KATRIN_1 [288]3 years ago

First we need to take the - signal

So the difference between the graphs y = -4x and y = 4x is that they are mirrored by the y-axis

Now we have the graph y = 4x and want the graph y = 4x + 3

We just need to move the graph y = 4x 3 units to the left

So the transformations we need is to move it 3 units to the left and to mirror it by the y-axis

A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes.
Paladinen [302]

Answer:

Answer:

\{ {{20x+30y=280} \atop {y=4x}} .{

y=4x

20x+30y=280

.

Where xx is the number of small boxes sent and yy is the number of large boxes sent.

Step-by-step explanation:

Let be xx the number of small boxes sent and yy the number of large boxes sent.

Since each small box can hold 20 books (20x20x ), each large box can hold 30 books (30y30y )and altogether can hold a total of 280 books, we can write the following equation to represent this:

20x+30y=28020x+30y=280

According to the information provided in the exercise, there were 4 times as many large boxes sent as small boxes. This can be represented with this equation:

y=4xy=4x

Therefore, the system of equation that be used to determine the number of small boxes sent and the number of large boxes sent, is:

\{ {{20x+30y=280} \atop {y=4x}} .{

y=4x

20x+30y=280

600,000 1/10 of what? Please help!!
igor_vitrenko [27]
600000 is 1/10 of "x", that means x = 10/10 or a whole, what is "x"?

\bf \begin{array}{ccll}
amount&fraction\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
600000&\frac{1}{10}\\\\
x&\frac{10}{10}
\end{array}\implies \cfrac{600000}{x}=\cfrac{\frac{1}{10}}{\frac{10}{10}}\implies \cfrac{600000}{x}=\cfrac{1}{10}
\\\\\\
\cfrac{600000\cdot 10}{1}=x

4) What is the equation of the line that passes through the points (3,0) and 2 points
liubo4ka [24]
Presume y=kx +b,then substitute (3,0)&(5,4),
When x=3,y=0,so 3k+b=0;
When x=5,y=4,so 5k+b=4;
Now u can know that k=2,b=-6.
The answer is:y=2x-6.
