Answer and step-by-step explanation:

I am assuming the equation is:

y + 2 = -\frac{3}{4}(x + 4)

It will be easier if we convert the fraction to a decimal, for now.

y + 2 = -0.75(x + 4)

Then we can simplify a bit, using the distributive property.

y + 2 = -0.75x - 3

Now, we want to have the y all by its self. So, let's subtract 2 on both sides.

y + (2 - 2) = -0.75x + (-3 - 2)

y = -0.75x - 5

Let's convert the decimal back into a fraction.

y = -\frac{3}{4}x - 5

Now we have our equation. To start graphing, let's plot the y-intercept. Our y-intercept is -5. So we can plot the point (0, -5). Now, we need to find the slope. The slope is -\frac{3}{4}. It's negative, which means that the line will start from the top right to the bottom left. That means that every time we move to the right one unit, we will move down 0.75 units. I hope this helps!

Find a polynomial function f(x) of degree 3 with real coefficients that satisfies the following conditions.
frosja888 [35]

Answer:

The polynomial will be f(x) = \frac{4}{9}x(x - 2)^{2}.

Step-by-step explanation:

The three degree polynomial function f(x) has zeros at x = 0 and at x = 4 having multiplicity 2.

Therefore, (x - 0) and (x - 4)² will be factors of the polynomial f(x).

Hence, the polynomial will be f(x) = Ax(x - 4)² .............. (1), where A is any constant that we have to evaluate.

Now, given that f(5) = 20

So, from the equation (1) we have

20 = A(5)(5 - 2)²

⇒ A = \frac{4}{9}

Therefore, the polynomial will be f(x) = \frac{4}{9}x(x - 2)^{2} (Answer)

3 + b/9 &lt; 4<br>show work please
Gekata [30.6K]

First, before multiplying to cancel the fraction, let's isolate x by subtracting both sides by 3:

b/9 < 1

To cancel out the fraction, we multiply both sides by 9:

x < 9
