Martin combined different amounts of orange juice, pineapple juice, and strawberry juice to make 1850 milliliters (ml) of fruit
stealth61 [152]
The answer is 450 ml.

First, we need to solve x (the amount of orange juice):
<span>x + (x + 100) + one half x = 1850
</span>x + x + 100 + 1/2 x = 1850

We can represent 1/2 as 0.5:

2x + 100 + 0.5x = 1850
2.5x = 1850 - 100
2.5x = 1750
x = 1750 ÷ 2.5
x = 700.

Thus, in the fruit punch, there is 700 ml of orange juice.

<span>The amount of pineapple juice combined was 100 ml more than the amount of orange juice. Therefore, there is 800 ml of pineapple juice (700 ml of orange juice + 100 ml more).
</span>
The amount of strawberry juice was half the amount of orange juice. Therefore, there is 350 ml of strawberry juice (700 ml of orange juice ÷ 2).

<span>The difference in the amounts of pineapple juice and strawberry juice Martin combined is 450 ml:
</span>the amounts of pineapple juice - the amounts of strawberry juice =
800 ml of pineapple juice - <span>350 ml of strawberry juice = 450 ml.

Given that (9,2) is on the graph of f(x), find the corresponding point for the function f(-3/4x)
never [62]

Answer:

(-\frac{8}{3},2)

Step-by-step explanation:

Since (9,2) is a point on the graph of f(x), we can say that:

f(9) = 2

Looking at the funtion f(-3/4x), what should the value of x be such that the input of the function becomes 2?

We would solve it by:

-\frac{3}{4}x=2\\\frac{-3x}{4}=2\\-3x=8\\x=-\frac{8}{3}

Hence, the new point on the graph is  (-\frac{8}{3},2)

If h(x) = 1/2x4 - 3x3, find h(4).
kvasek [131]
<h2>Solving functions given the input</h2><h3>Answer:</h3>

h(4) = -64

<h3>Step-by-step explanation:</h3>

Given:

h(x) = \frac{1}{2}x^4 -3x^3\\

h(4) = \frac{1}{2}(4)^4 -3(4)^3 \\ h(4) = \frac{1}{2}(256) -3(64) \\ h(4) = 128 -192 \\ h(4) = -64
