Answer:

B) Jacob has four more nickels than dimes in his pocket, for a total of $1.25. What is x, the number of dimes in his pocket?  

Step-by-step explanation:

The equation is multiplying the number of dimes (x) by the value of a dime 0.10. it is also adding 4 to the value of x ( 4 more nickels than dimes) and multiplying that by the value of a nickel.

Answer:

Given equation : 0.05(x + 4) + 0.10(x) = 1.25

1 dime = $0.10

1 nickel = $0.05

So, x is the no. of dimes in equation and x+4 is the number of nickels

So, Option B is true  Jacob has four more nickels than dimes in his pocket, for a total of $1.25.

0.05(x + 4) + 0.10(x) = 1.25

0.05x +0.2 + 0.10x = 1.25

0.15x +0.2= 1.25

0.15x = 1.25-0.2

0.15x = 1.05

x = \frac{1.05}{0.15}

x =7

Hence  the number of dimes in his pocket is 7

What are the zero(s) of the function f(x)=<img src="https://tex.z-dn.net/?f=%5Cfrac%7B4x%5E%7B2%7D-36x%20%7D%7Bx-9%7D" id="TexFo
Contact [7]

Answer:

D

Step-by-step explanation:

The function will be zero when the numerator is equal to 0. So, set the numerator equal to 0 and solve:

0 = 4 {x}^{2}  - 36x

I will use the quadratic formula:

\frac{ 36  +  \sqrt{ {36}^{2}  - 4(4)(0)} }{2(4)}  \\  \frac{  36 + 36}{8}  = 9

Therefore, x = 9 is a 0. Let's check with subtracted root now:

\frac{ 36   -    \sqrt{ {36}^{2}  - 4(4)(0)} }{2(4)}  \\  \frac{ 36  -  36}{8}  =  0

It appears 0 is also a root.

Therefore, the answer is D.
