Answer:
M<1 80 by the corresponding angles postulate
Step-by-step explanation:
Answer:
Sheet metal remaining = 4.1x
cost per square foot of sheet metal = $30
Step-by-step explanation:
Total sheet metal bought = 7.6 ft2
Total sheet metal used = 3.5 ft2
Given equation:
7.6x − 3.5x = 123
Where,
x = cost per square foot
7.6x − 3.5x
Sheet metal remaining = 4.1x
7.6x − 3.5x = 123
4.1x = 123
x = 123 / 4.1
x = $30
Cost per square foot = $30
Answer:
"vertical" (y axis), "lateral" (x axis), and "horizontal" (z axis)
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
x can have any real value - the domain is (-∞, ∞).
f(x) cannot be 0 or negative, no matter how negative x is, - the range is (0, ∞)

Answer:</h3>
D (0, 5), (5, 0)
<h3>
Step-by-step explanation:</h3>
Anything with -5 and 0 will not satisfy x+y=5. This eliminates the first three choices.
___
It is easiest to check the offered answers. You can also solve this graphically, or by solving the simultaneous equations.
You can, for example, square the first equation and subtract the second:
... (x+y)² -(x²+y²) = 5² -25
... 2xy = 0
This will be true for x=0 or for y=0, so (0, 5) and (5, 0) are solutions to the pair of equations.
