Answer:
a.
Step-by-step explanation:
A catenary looks a lot like a parabola. Only graph "a" has that appearance.
___
A graphing calculator can help you choose, or you can recognize the nature of the terms of the sum.
e^x looks like graph D; e^-x looks like graph B. Their sum will always be positive, so cannot create graph C. At x=0, the average of the two graphs B and D will be 1, corresponding to the minimum of graph A.
Answer:
Below!
Explanation:
A system of equations with infinite solutions defines that both the equations are identical and are overlapping when the lines are graphed. An example could be y = 5x + 9 and y = 5x + 9. These sets of equations have infinite solutions because they are the same and when graphed, they overlap.

Answer:
7. y = x + 4
8. y = -3x - 2
Step-by-step explanation:
7. m = 1 , b = 4
y = mx + b will be y = x + 4
8. (1,-5) and (-3,7)
Slope (m) = 7 - (-5) / -3 - 1
= 7 + 5 / -4
= 12 / -4
= -3
y = mx + b will be y = -3x -2
You didn't supply a list. The so-called rigid transformations of translation, rotation and reflection create congruent triangles.
Generally it's dilation by a factor about a point is preserves similarity but not congruency. Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.
precision for 40 feet is 1/2 foot
12 cm is 1/2 cm
for 9 1/2 in is 1/4 in
