Answer:

420 - x grams.

Step-by-step explanation:

Aderyn is making a vegetable stew for = 6 people.

A recipe indicates that 5 ounces of finally diced onions are needed for = 2 people

1 ounce = 28 grams.

So for 1 people onions are needed = 5/2 = 2.5 ounces or 70 grams.

Therefore, finally diced onion are needed for 6 people = 70 × 6 = 420 grams.

Aderyn needs total 420 grams of diced onion to make her vegetable stew for 6 people.

Let she has already prepared some diced onions = x

then she needs more to make her vegetable stew = 420 - x.

What is the result of subtracting the second equation from the first? \begin{aligned} -7x-y &= 0 \\\\ 7x+8y &= -6 \end{a

Kitty [74]

Answer:

$-14x-9y=6$

Step-by-step explanation:

We are given with two equations

first equation is $-7x-y=0$

second equation is

$7x+8y=-6$

we find the result of subtracting two equation

subtract the second equation from the first, so

first equation - second equation, multiply second equation by -1 and then add it with first equation

$-7x-y=0$

$-7x-8y=+6$

Now add both equations, we get

$-14x-9y=6$

The variables x and y are directly proportional, and y=2 when x=3. what is the value of y when x=9?

laiz [17]

X varies directly as y
x = ky
3 = 2k
k = $\frac{3}{2}$
when x =9
9 = $\frac{3}{2}$ y
$\frac{18}{3}$ = y
∴y = 6

Which statement is true about the extreme value of the given quadratic equation? y = -3x2 + 12x − 33

Zina [86]

Answer:

The equation has a maximum value with a y-coordinate of -21.

Step-by-step explanation:

Given

$y =-3x^2 + 12x - 33$

Required

The true statement about the extreme value

First, write out the leading coefficient

$Leading = -3$

$-3 < 0$ means that the function would be a downward parabola;

Downward parabola always have their vertex on top of the parabola and as such, the function has a maximum value.

The maximum value is:

$x = -\frac{b}{2a}$

Where:

$a= -3; b =12; c =-33$

So, we have:

$x = -\frac{12}{2 * -3}$

$x = -\frac{12}{-6}$

$x =2$

Substitute $x =2$ in $y =-3x^2 + 12x - 33$

$y = -3*2^2 + 12 * 2 - 33$

$y = -21$

<em>Hence, the maximum is -21.</em>
