Question 3:

O (7 x 50) - (7 x 2) = 350 – 14 = 336

Question 3:

O (9 x 80) + (9 x 1) 729

Step-by-step explanation:

Distributive Property is used in algebraic expressions, to divide the equation, to make it easier to solve. For question 1,  since it was 20, you must subtract 8 from that answer, because 20 is 1 more than 19. For question 2, (2 x 9) + (2 x 3) would be the same thing as 2(9+3).

Answer:

Step-by-step explanation:

The reasonable domain for the function 2 ( l + w ) = 64 is:

5, 10, 15, 20, and 25

The graph of the function 2 ( l + w ) = 64 is given below.

A function is defined as a relation between a set of inputs having one output each.

We have,

A function of the perimeter of a rectangle:

2 ( l + w ) = 64

Here,

l = length and w = width

We need to find the value of length and width such that the perimeter of the rectangle is 64.

Now,

2 ( l + w ) = 64

l + w = 32

This means the combined measure of length and width must give us 32.

We need to write as a function for length where width is given.

We can assume the width to be: 5, 10, 15, 20, and 25.

Now,

l + 5 = 32

l = 27

l + 10 = 32

l = 22

l + 15 = 32

l = 17

l + 20 = 32

l = 12

l + 25 = 32

l = 7

We consider,

Width = 5, 10, 15, 20, and 25 to be the domain.

Length = 27, 22, 17, 12, and 7 to be the range.

We consider width values as the x-axis and length values as the y-axis.

The graph is given below.

Thus the reasonable domain for the situation given above is:

5, 10, 15, 20, and 25

The graph of the function 2 ( l + w ) = 64 is given below.

let the first equation be l1 and the second equation be l2

then the product of L1.L2=1 the line is perpendicular and l1=l2 the line is parallel

Answer:

steps below

Step-by-step explanation:

From the graph: parabola pass (0,4) (3,4) (1,2)

equation: y = ax² + bx + c

(0,4): c = 4

(3,4): 9a + 3b + 4 = 4       9a+3b = 0       3a + b = 0   ... (1)

(1,2):  a + b + 4 = 2            a+b = -2   ... (2)

(1)-(2): 2a = 2        a = 1

(2):      b = -3

parabola equation: f(x) = x² - 3x +4

(a)  f(3) = 3² - 3*3 + 4 = 4

(b) normal line: parallel to tangent line y = 3x -5 at (3,4)

    slope of line N: -1/3   pass (3,4)

    equation of N: (y-4)/(x-3) = -1/3         y-4 = -1/3 x + 1

     line N: 1/3 x + y - 5 = 0

Answer:.

Step-by-step explanation:

(5x² - 13x -28)/(x-4) = (x-4)(5x+7) so x = -7/5  and x = 4 are the two factors of the given polynomial.

The factors of a polynomial are those values of x for which the given polynomial satisfies.

According to the given question we have to divide a polynomial            (5x² - 13x -28) by (x - 4).

(5x² - 13x -28)/(x-4) = (x-4)(5x) + (7x - 28).

(5x² - 13x -28)/(x-4) = (x-4)(5x+7).

So, the obtained factor is (5x+7) = 0.

∴ 5x + 7 = 0

5x = -7

x = -7/5 is a factor of the given polynomial and by substituting these value in x.

(5x² - 13x -28)

5(-7/5)² - 13(-7/5) - 28 = 0

5(49/25) + 91/5 - 28 = 0

49/5 + 91/5 - 28 = 0

140/5 - 28 = 0.

28 - 28 = 0

0 = 0     ( hence satisfied that -7/5 is a factor of the given polynomial ).

Step-by-step explanation:

Using the point slope formula

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is a point on the line
