Answer:

A)The slope of the graph is 1

B) The table is 3

C) The equation is 1/2

D) The table

Step-by-step explanation:

y2-y1/x2-x1=the slope

Pick two undefined points {such as 5,0 and 0,-5)

5-0/0+5=1

The slope is 1.

~~~~~~~~~~

Same equation of slope, you just have to find two points (I chose 2,2 and 4,3

The slope of the equation y=0.5x+1 is 1/2 or 0.5

~~~~~~~~~~

You choose two points (I chose 2,9 and 1,6)

Slope equation

9-6/2-1=3/1=3

Slope is 3

~~~~~~~~~~~

The greatest change is in the table. You know this because it has the greatest slope and if you draw it out on a graph, it has the most significant change.

Good luck!

Answer:

5x + 4y + 12 = 0

Step-by-step explanation:

Start with the point-slope equation of a straight line: y - k = m(x - h):

Here we are given the point (h, k): (-8, 7) and the slope m = -5/4. Inserting this info into the equation give above, we get: y - 7 = (-5/4)(x + 8).

We must put this equation into "standard form" Ax + By + C = 0.

Multiply all three terms by 4 to remove fractions: 4y - 28 = -5(x + 8), or

4y - 28 + 5x + 40 = 0

Rearranging these terms, we get 5x + 4y + 12 = 0, which is the desired equation in standard form.

The daily cost of producing x high performance wheels for racing is given by the following function, where no more than 100 whe

algol [13]

Answer:

The production would be 25 wheels,

Lowest average cost is $ 123.75

Step-by-step explanation:

Given cost function,

$C(x) = 0.09x^3 - 4.5x^2 + 180x$

Where,

x = number of wheel,

So, the average cost per wheel,

$A(x) = \frac{C(x)}{x}=\frac{0.09x^3-4.5x^2 + 180x}{x}=0.09x^2 - 4.5x + 180$

Differentiating with respect to x,

$A'(x) = 0.18x - 4.5$

Again differentiating with respect to x,

$A''(x) = 0.18$

For maxima or minima,

$A'(x) = 0$

$0.18x - 4.5 = 0$

$0.18x = 4.5$

$\implies x = \frac{4.5}{0.18}=25$

For x = 25, A''(x) = positive,

i.e. A(x) is maximum at x = 25.

Hence, the production would be 25 wheels for the lowest average cost per wheel.

And, lowest average cost,

A(x) = 0.09(25)² - 4.5(25) + 180 = $ 123.75

Maddie spent $76 on shoes. That is 43% of her savings account. What is was the total amount of Maddie's savings account before p

marishachu [46]

Answer:

The total saving =$ 176.64

Step-by-step explanation: let Maddie's saving amount be x.

Maddie spent = $76 maddie spent in percent = 43%

We know, 43% of x = $76 or, 0.43x = $76 or, x = $76/0.43 or, x = $176.74

total savings = $176.74
