Answer:

Step-by-step explanation:

f"(x) < 0, which means the function is concave down at all values of x.

For any such function, within the domain of a ≤ x ≤ b, the secant line S(x) is below the curve of f(x), and the tangent line T(x) is above the curve of f(x).

Here's an example:

Enter the equation of the line in slope-intercept form.

ad-work [718]

Answer:

$y = \frac{7}{4}x +14$

Step-by-step explanation:

Given

$y = \frac{7}{4}x + 4$

Required

Determine the equation of line that passes through (-8,0) and parallel to $y = \frac{7}{4}x + 4$

Parallel lines have the same slope.

In $y = \frac{7}{4}x + 4$

The slope, m is

$m = \frac{7}{4}$

because the general form of a linear equation is:

$y = mx + b$

Where

$m = slope$

So, by comparison:

$m = \frac{7}{4}$

Next, is to determine the equation of line through (-8,0)

This is calculated using:

$y - y_1 = m(x - x_1)$

Where

$m = \frac{7}{4}$

$(x_1,y_1) = (-8,0)$

So, we have:

$y - 0 = \frac{7}{4}(x -(-8))$

$y - 0 = \frac{7}{4}(x +8)$

$y - 0 = \frac{7}{4}x +\frac{7}{4}*8$

$y - 0 = \frac{7}{4}x +7*2$

$y - 0 = \frac{7}{4}x +14$

$y = \frac{7}{4}x +14$

Mitch mixes 5 parts white paint to 9 parts blue paint. If he has 4 qt of white paint, how much blue paint would he need?

tatuchka [14]

Answer:

7.2 qt

Step-by-step explanation:

1. Determine how much blue paint is needed in comparison to white paint

9 ÷ 5 = 1.8

For every 1 part of white paint, 1.8 times that amount of blue paint is needed.

2. Multiply the 4 qt of white paint by 1.8

4 · 1.8 = 7.2

Answer: x = $-\frac{10}{3} - \frac{2y}{3}$

Step-by-step explanation:

-3x -2y = 10 Get x alone by add 2y to both sides

+2y +2y

-3x = 10 + 2y Divide both sides by -3

x = -10/3 - 2y/3
