Needs Clarification Please! Explain how the graph of each given function is a transformation of the graph of y = x^2

Mathematics

Katen [24]3 years ago

In 1. the graph would open down because of the negative sign in front of the 2.  The 2 in front of the x, would excel the growth of the graph by a factor of 2, making it more narrow.

on the second problem the -5, being that it is tied to the x and being squared and inside of the (), would cause the graph to shift 5 units to the right (always opposite of the sign in front of the number.

What si the slope of y=-5x+4x
frosja888 [35]

Answer:

Use the slope-intercept form y=mx+b to find the slope m. m=−1

Step-by-step explanation:

lets take the x's away from: -5x+4x

That will be -5+4

-5+4=-1

Because remember:

When adding positive numbers, count to the right.

When adding negative numbers, count to the left.

When subtracting positive numbers, count to the left.

When subtracting negative numbers, count to the right.

I hope this helps.       :)

julia-pushkina [17]

Answer: 4 people

Step-by-step explanation:

4 times 1/5= 4/5

The 4 goes on top ( numerator ) and the 5 would go on the bottom ( denominator )

Also another way to solve this is to use decimal form.

4 times 0.2 ( 0.2=1/5 )= 0.8

* PLEASE HELP CAN'T SOLVE *
emmainna [20.7K]

Answer:

Y=(4x)^3

Y=64x^3

Step-by-step explanation:

Y=(3√x)÷4

Making X subject of formula

4y= (3√x)

(4y)^3= (3√x)^3

(4y)^3 = X,

Replacing Y with X

Y=(4x)^3

Y=64X^3

forrest has pennies, nickels, dimes, and quarters in a cookie jar- a total of 201 coins. He has twice as many nickels as dimes a
Digiron [165]
We use letters to represent the unknown coins.
P for pennies that worth 1 cents
N for nickels that worth 5 cents
D for dimes that worth 10 cents
Q for quarters that worth 25 cents.

<span>"He has twice as many nickels (N) as dimes (D)" So D=2N
</span><span>"and four times as many pennies (P) as quarters (Q)." So Q=4P
</span>
Number of coins equals P+N+D+Q=P+N+2N+4P (Dimes and quarters are written in terms of nickels and pennies, respectively)

So, number of coins is equal to 5P+3N=201. Thats is the first equation (I)
To write the second equation, use cents of coins. 12.10 $ in coins can be shown as
 
5P. 1 cent + 3N. 5 cent=1210 cents or simply 5P + 15N=1210 (Second equation)

We have two equations and two unknowns so it is soluble.
number of coins: 5P+3N=201 (I)
cents of coins: 5P+15N=1210 (II)
Use the substitution method. (II) - (I)=12N=1009 
N=1009/12=84 ( Actually it is 84.08)
D=2N=168
P= -10
Q=-40  
Number of pennies and quarters are <span>meaningless. They can't be negative. So they should be something wrong in the question.</span>
