Elena is making a grape drink. the recipe calls for 2 parts grape juice concentrate to 6 parts water. elena would like to make 8

SashulF [63]

Answer: 20 oz of juice concentrate and 60 oz of water.

Explanation:

Translate the word statements into algebraic expressions to set a system of equations that you can solve.

1) Name the variables:

j: parts of juice concentrate
w: parts of water

2) Statement one, 2 parts juice concentrate to 6 parts water, translates into a proportion:

j / w = 2 / 6

3) Statement two, 80 oz of the drink, tanslates into an equality:

j + w = 80

4) Solve the system to find how many oz of juice concentrate and water Elena needs:

a) System:

j / w = 2 / 6

j + w = 80

b) Solve for w in the first equation: w = 6j / 2 = 3j

c) Substitute w in the second equation: j + 3j = 80

d) Combine like terms: 4j = 80

e) Use division property of equality: j = 20

f) Substitue in w = 3j: 3 = 3(20) = 60.

5) Solution: j = 20, w = 60.

6) Verify:

j / w = 20 / 60 = 2 / 6 ⇒ right
j + w = 20 + 60 = 80 ⇒ right

Choose the function that correctly identifies the transformation of f(x) = x2 shifted three units to the left and five units up.

8090 [49]

Answer: $g(x) = (x+3)^2 + 5$

Step-by-step explanation:

Here, the given function,

$f(x) = x^2$

Which is the equation of parabola, having vertex (0,0)

When the function f(x) is transformed to a new function,

Then we can write the new equation of parabola,

$g(x) = a(x-h)^2+k^2$

Where h shows the horizontal shifting and k shows the vertical shifting

While a shows the compression,

Here compression is not occur.

Therefore, a = 1

Now, f(x) is shifted three unit to the left

Therefore, h = - 3 ( In left side we take negative shifting)

Again, f(x) is shifted five unit up,

k = 5

(Note: In case of downward shifting the value of k will be negative)

By putting the values of a, h and k in the above transformed equation,

We get, $g(x) = (x+3)^2 + 5$

Which is the required transformed equation.

⇒ Third Option is correct.
