Write an inequality equation equivalent to 3x – 4y = 8?

Mathematics
1 answer:
Natalka [10]3 years ago
4 0

Answer:

3x-4y=8

-4y=8-3x (subtracting 3x from each side of the equation)

-4y/-4=(8-3x)/-4 (dividing each side of the equation by -4)

y=-2+3/4x

y=3/4x-2

Step-by-step explanation:

By what percent will a fraction change if its numerator is decreased by 20% and its denominator is decreased by 60%?
Vedmedyk [2.9K]

Answer:

The fraction will increase by 100%

Step-by-step explanation:

Say the fraction is x/y. The question is telling us to decrease x by 20% (i.e. 0.8x) and to decrease y by 60% (i.e. 0.4y):

= \frac{0.8x}{0.4y}\\= 2 (\frac {x}{y})

You can see that by applying these changes, the new fraction is actually double the old fraction (i.e. will increase by 100%).

The graph of the function f(x) = (x − 3)(x + 1) is shown.
Travka [436]

Answer:

Real values of x where x < -1

Step-by-step explanation:

Above the x-axis, the function is positive.

The function is decreasing when the gradient is negative.

The function has a positive

{x}^{2}

coefficient, therefore the vertex is a local minimum;

This means the gradients are negative before the vertex and positive after it;

To meet the conditions therefore, the function must be before the vertex and above the x-axis;

This will be anywhere before the x-intercept at x = -1;

Hence it is when x < -1.
