Answer:

Step-by-step explanation:

For a quadratic equation in the from

x² + Bx = C,

to complete the square, we need to add (B/2)² to both sides

in this case

x² + 8x = 4

we will need to add (8/2)² = 4² = 16 to both sides

Function 1 is defined by the equations r=3/4t +5<br> Function 2 is defined by the following table

Dvinal [7]

Function 2 has a greater y-intercept

<h3>Graphs</h3>

Graphs can be used to represent functions, equations, tables and relations

<h3>Equations</h3>

The equation of function 1 is given as:

$r =\frac 34t + 5$

To calculate the y-intercept, we set t to 0.

So, we have:

$r =\frac 34 \times 0 + 5$

$r =5$

For the table of function 2, the y-intercept is 5.25

By comparison:

5.25 is greater than 5

Hence, function 2 has a greater y-intercept

Find the perimeter and area of length 3cm and width 5 cm

Anni [7]

L = 5 and w = 3

Perimeter = 2(l + w)
P = 2(5 + 3)
P = 2(8)
P = 16 cm

Area = l*w
Area = 5*3
Area = 15 cm^2
