LuckyWell [14K]

Answer:

2x+5\ minutes

Step-by-step explanation:

Given:

Sam takes x minutes yo walk from home to library.

And takes 5 minutes more to walk from the library to school than from home to the library.

Express the total time taken for Sam to walk from home to school via the library in terms of x.

<u>Solution:</u>

Time taken by Sam to walk from home to library = x\ minutes

Time taken by Sam to walk from library to school = x+5\ minutes

Total time taken by Sam to walk from home to school via the library = Time taken to walk from home to library + Time taken to walk from library to school

Total time taken = x+x+5=2x+5

Therefore, the total time taken for Sam to walk from home to school via the library is 2x+5\ minutes

Identify the parent function that can be used to graph the function f(x)= -9(x+5)2
olga nikolaevna [1]

Answer:

The parent function that can be used to graph f(x)=-9(x+5)^2 is:

f(x)=x^2

Step-by-step explanation:

We are asked to find the parent function that can be used to graph the function f(x) which is given as:

f(x)=-9(x+5)^2

We know that from the given options the parent function that best represents the relationship or that can be used to graph the function f(x) is:

f(x)=x^2

since the function f(x)=-9(x+5)^2 is just a transformation of the parent function the transformation that is applied is a combination of a dilation with a scale factor '-9' and a translation '-5' units to the left and a reflection along 'x' axis.

Hence, the parent function is:

f(x)=x^2

The perimeter of a rectangular section of a roof is 96 yards. The length is 18 yards. What equation could you use to find the wi
Kruka [31]

Answer:

36+2w=96

2w=96-36=60

w=60/2=30

Step-by-step explanation:

perimeter is 96, that means length + length + width + width = 96.

say l is length and w is width.

since we know length is 18, 18+18+width+width = 96

36+2w=96

2w=96-36=60

w=60/2=30
