Answer:
True, A linear equation determines a line in the xy-plane.
Step-by-step explanation:
A linear equation is in the form of Px + Qy = R where P , Q and R are constants.
Let us take an example 2x +3y = 6
When we plot the above equation in graph we get a line in xy plane.(as shown below) Since, there are two variables, x and y, then will it be possible, only on the xy plane.
It is also clear from the graph that linear equation shows the relation between x and y axis. Thus, it is true to say a linear equation determines a line in the xy-plane.
Answer:
Exact form - x= - 22/5
Decimal form - x=-4.4
Mixed Number form - x= -4 2/5
Step-by-step explanation: Isolate the variable by dividing each side by your factors that don't contain variables.
14,999(1+.o825)^4= 20,595. $429x48 months= 20,592
Interest rate 8 1/4%
Check 20592/14999= 1.37289
Log(1.37289)/ log(1.0825)= 3.99 years

Answer:
1. the longer frame (B) has the shorter width
2. the shorter width is 6 3/7 inches, area divided by length
Step-by-step explanation:
The relation between area, length, and width is ...
A = LW
Then the width is ...
W = A/L . . . . . inversely proportional to length
__
1. Since length and width are inversely proportional (when area is constant), the shorter width will be associated with the longer length. Frame B will have the shorter width.
__
2. The width of frame B is ...
W = A/L = (45 in²)/(7 in) = 45/7 in = 6 3/7 in
