Step-by-step explanation:
The slope intercept form of a line is given as:
y = mx + c
Where m is the slope and c is the y-intercept
Let's rearrange the equation given in this form:
2x - 5y = -11
5y = 2x + 11
y = 2/5 x + 11/5
So the slope is 2/5
Slope of line that is perpendicular to this is the "negative reciprocal" of this slope. Which means the slope of perpendicular line would be -5/2
Thus, equation would become: y = -5/2x + c
Now we need to find c. For this we plug in 7 into x and 5 into y and solve for c [(7,5) is the point given]. Thus,
Thus, the equation of perpendicular line is:
Answer:
3 + x = 7

Answer:
(b) tangible approximation of the product that often look and feel like the product
Step-by-step explanation:
"Physical" means it exists as an object in the real world, not just as a model on a computer screen. "Prototype" means it is an approximation of the finished product, lacking in one or more details of appearance, structure, or functionality.
Part B is saying to equal the both equations, so
5x + 2 = 5x + 5
Take a look, we have the same multiplicative to our variable, but we have different sums, so, if we just say x = 0 we wil have:
5.0 + 2 = 5.0 + 5
0 + 2 = 0 + 5
2 = 5
And of course it's not true, 2 will never be equal to 5, so we can say there's no solution for x.
Another way to see this is:
5x + 2 = 5x + 5
5x - 5x = 5 - 2
0 = 3
0 of couse isn't equal to 3.
