Which equations represent the line shown in the graph?
zaharov [31]
The given graph is a straight line passing through points (-4, -3) and (1, 5)
Equation in point slope form is y + 3 = (5 - (-3))/(1 - (-4)) (x - (-4))
y + 3 = 8/5(x + 4)
y + 3 = 8/5x + 32/5
y = 8/5x + 32/5 - 3
y = 8/5x + 17/5

Multiplying through by 5 gives
5y = 8x + 17
-8x + 5y = 17
Options B and C are the correct answers.

Which properties are present in a table that represents an exponential function in the form y=bx
Bas_tet [7]

Answer:

y-intercept (0,1)

multiplicative rate of change: b

Step-by-step explanation:

If a table represents an exponential function of the form  y=b^x, then the y-value that corresponds to x=0 is 1.

In other words, the y-intercept (0,1) must be present in the table.

Also the ratio of a subsequent y-value to the previous y-value should give a value of b.

In other words the multiplicative rate of change from the table must be equal to b.

steposvetlana [31]

Answer:

5 5/8.

Step-by-step explanation:

2 1⁄4 × 1 1⁄2 × 5⁄3

Change to improper fractions:

= 9/4 x 3/2 x 5/3

= (9x3x5) / (4x2x3)

= 9x5 / 4x2         (3 is common)

= 45/8

= 5 5/8.

My square orchid garden abuts my house so that the house itself forms the northern boundary. The fencing for the southern bounda
lilavasa [31]

Answer:

The total cost of the fencing as a function of side is C = 8\cdot x.

Step-by-step explanation:

Dimensionally speaking, the total cost is equal to the product of length and cost per length. Given that orchid garden has a square form, there is only an input: Side (x), measured in feet. Therefore, the total cost of fencing is represented by the following formula:

C = (c_{west} + c_{south} + c_{east})\cdot x

Given that c_{west} = c_{east} = 2\,\frac{\$}{ft} and c_{south} = \$\,4\,\frac{\$}{ft}, the total cost of the fencing as a function of side is:

C = 8\cdot x
