Y=12+2x
y represents the number of pieces she now knows, x represents the number of weeks she has taken lessons, 2 is the slope (the number of pieces she'll learn each week), and 12 is the y intercept (the number of pieces she knew before taking lessons).

To solve the equation for 11 weeks, we replace x with 11.

2×11+12= 24
y=24

PLEASE help me...Suck at math. find the following using the given triangle.

Ulleksa [173]

To find the perimeter just add the sides

5+5+6 = 16

To find the area, you need to use the following formula

$area = \frac{1}{2}bh$
we know b but we need to find the height. We can find the heigh by using pythagorean theorem $a^2 + b^2 = c^2$

height = $a^2 + 3^2 = 5^2$
$a^2 + 9 = 25$
$a^2 = 25 - 9$
$a^2 = 16$
$a = \sqrt{16} = 4$
h = height = 4

$area = \frac{1}{2}\times 6\times 4 = 12cm^2$

Cost:

6.00 per cm^2 = 6.00 x 12 = $72.00 dollars

what does it mean to be a function how can you determine functionality of a relation or eqaution graph

mylen [45]

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.
