How is the parent function y=x2 related to the given function Y=3(x+1)2?

Nuetrik [128]

Parent function: y = f(x) = x^2

given function: y = g(x) = 3 (x+1)^2

=> g(x) = 3 * f(x + 1)^2

So, from the point of view of graphs, the given function, g(x), is the parent function, f(x) = x^2, shifted one unit to the left and amplified by a factor of 3.

The sum of twelve and a number is no greater than the sum of twice the number and -8

krok68 [10]

The sum of 12 and a number
(12 + n)

is no greater
< =

then the sum of twice the number and 8
(2n +(-8)) = (2n - 8)

so we have :
(12 + n) < = (2n - 8)

three consecutive integers can be represented by n, n+1 and n+2. if the sum of three consecutive integers is 57 what are the int

Paul [167]

18,19 and 20 are the integers.

Step-by-step explanation:

Given three integers are;

n, n+1, n+2

According to given statement;

n+(n+1)+(n+2)=57

$n+n+1+n+2=57\\3n+3=57\\3n=57-3\\3n=54\\Dividing\ both\ sides\ by\ 3\\\frac{3n}{3}=\frac{54}{3}\\n=18$

n=18

n+1 = 18+1 = 19

n+2 = 18+2 = 20

18,19 and 20 are the integers.

\dfrac12(10x + 20y +10z) = 2 1 (10x+20y+10z)=start fraction, 1, divided by, 2, end fraction, left parenthesis, 10, x, plus, 20

iragen [17]

Answer:

5x + 10y + 5z

Step-by-step explanation:

Given the expression

$\frac{1}{2}(10x+20y+10z)\\$

Expand the parenthesis using the distributive law;

$\frac{1}{2}(10x)+ \frac{1}{2}(20y)+\frac{1}{2}(10z)\\= \frac{10x}{2} + \frac{20y}{2} + \frac{10z}{2}\\= 5x + 10y + 5z$

Hence the required solution is 5x + 10y + 5z
