Kenny ordered guitar strings for glenn’s guitar shop. the premium guitar strings are $4.50 apiece. the standard guitar strings are $1.50 apiece. the bill smeared in the rain, but kenny knows he ordered a total of 80 strings for $225.

Kenny ordered 45 standard guitar strings and 35 premium gutar strings.

Step-by-step explanation:

I think the question refers to how many strings of each kind he bought.

Let

x = number of standard guitar strings

y = number of premium gutar strings

The sum of x times their individual cost and y times their individual cost is equal to the global cost.

1.50x + 4.50y = 225 [1]

The sum of x and y is equal to the total number of strings.

x + y = 80

x = 80 - y [2]

Let's replace [2] in [1],

1.50.(80-y) + 4.50y = 225

120 - 1.50y + 4.50y = 225

- 1.50y + 4.50y = 225 -120

3.00y=105

y = 35

If we replace y = 35 in [2], we get

x = 80 - 35 = 45

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
