Which equation shows the point slope form of the line that passes through (5,1) and has a slope of 1/2

arsen [322]

Answer:

3rd option, $y-1 = \frac{1}{2} (x-5)$

Step-by-step explanation:

To find out which option is correct, we can write the equation in point-slope form ourselves.

Use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation in point-slope form. Substitute the $m$ , $x_1$ , and $y_1$ for real values.

Since $m$ represents the slope, substitute $\frac{1}{2}$ in its place. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, substitute the x and y values of (5,1) into the formula as well. Substitute 5 for $x_1$ and 1 for $y_1$ . This gives the following equation:

$y-1 = \frac{1}{2} (x-5)$

Which equation represents y= -x^2 + 6x + 7 in vertex form ?

Drupady [299]

we are given

$y= -x^2 + 6x + 7$

we can use vertex form parabola formula

$y= a(x-h)^2+k$

so, we can complete x square

$y= -(x^2 - 6x - 7)$

$y= -(x^2 - 6x - 7+3^2-3^2)$

$y= -(x^2 - 6x +3^2-16)$

$y= -(x-3)^2+16$

so, option-A........................Answer

A farmer is going to divide her 30 acre farm between two crops. Seed for corn costs $15 per acre. Seed for wheat costs $30 per a

Deffense [45]

Answer:

$3200

Step-by-step explanation:

The total area of land is 30 acre. Let x represent the area in acre that corn is planted and y represent the area in acre that wheat is planted. Therefore:

x + y = 30 (1)

Also, the farmer can spend at most $750 on seeds. Corn cost $15 per acre, maize cost $30 per acre. Hence:

15x + 30y ≤ 750 (2)

Also, x and y > 0

The profit is given by the function:

Profit = 100x + 110y

Graphing equation 1 and equation 2 and solving, we get the points:

(10, 20)

Hence the maximum profit is at:

Max profit = 100(10) + 110(20) = $3200
