Yes, the equation specifies a function with independent variable x.
Equation: 6x + 19y = 7
This can be put in y = mx + b form,
6x + 19y = 7
19y = -6x + 7
y = -
x + 
Since the equation can be put in the form of a linear function, the domain is all read numbers (-∞,∞) or -∞ < x < ∞ .

Answer:
a. x = 7
b. x = 36/5
Step-by-step explanation:
<u>Points to remember</u>
The ratio of of corresponding sides of similar triangles are equal.
<u>a). To find the value of x</u>
From the figure 1 we get two similar triangles, ΔABC and ADE
We can write,
AB/AD = AC/AE
3/6 = x/(x + 7)
3(x + 7) = 6 * x
3x + 21 = 6x
6x - 3x = 21
3x = 21
x = 21/3 = 7
<u>b). To find the value of x</u>
From the figure b we get
ΔABC ~ ΔEDF
AB/DE = BC/DF
4/5 = x/9
x = (4 * 9)/5 = 36/5
Answer:
Below.
Step-by-step explanation:
Part A No. That's not the most specific shape.
Quadrilaterals can be many shapes regular and irregular.
Part B. A rectangle and a rhombus are both types of parallelogram which has 2 pairs of parallel sides. A rectangle and a rhombus are 2 specific types of parallelogram.
In the case of a rectangle it is a parallelogram with 4 right angles and a rhombus is a parallelogram with all sides equal in length,
