Answer:
<em></em>
Step-by-step explanation:
Functions have independet variables(the value of the variable could be any number, we have no restrictions) and dependent variaariables(the values of this variables depends of idependent variables)
the problem says that <em>x</em> is the independent variable, so we say that <em>y</em> is a dependent variable. Dependent need to be replaced by funcion notation, in this case we use <em>y=f(x)</em>
So we raplace it in the equation and we have:
<em></em>
we solve for <em>f(x)</em> passing <em>-6x</em> and <em>-9</em> to the right side and changing the signs, and we get:
<em></em>
G(x) = x - 3
The - 3 in this question will move the graph down by 3.
Compare the points made by f(x) and g(x)
f(x)
(0,0);(1,1);(2,2)
g(x)
(0,-3);(1,-2);(2,-1)
Therefore, the answer is D.
The area of a rhombus can be found by using the formula:
A = (1/2)(d1)(d2)
Area = (1/2)(8)(6)
Area = 24 cm^2
Your other option is to remember that in a rhombus the diagonals bisect each other, and form right triangles. So you have 4 right triangles each with sides of 4 cm (1/2 of 8 cm) and 3 cm (1/2 of 6 cm). 4 x [(1/2) x (4)(3)] = 4 x 6 = 24 cm^2.
A is the correct answer because the y-intercept is -2 and the slope is 3 because it goes up 3 units.
