Answer:
a = 9 + b - c → D
Step-by-step explanation:
To cancel the square root of one side of an equation square the two sides
Examples:
If [tex]\sqrt{x}[/tex] = 5, to find x square the two sides to cancel the square root
([tex]\sqrt{x}[/tex] )² = (5)², then x = 25
If [tex]\sqrt{a+b}[/tex] = 7, to find a + b square the two sides to cancel the square root
([tex]\sqrt{a+b}[/tex] )² = (7)², then a + b = 49
Now let us solve the question
To solve it for a square the two sides then keep a on the left side and move b, c to the other side
∵ [tex]\sqrt{a-b+c}[/tex] = 3
→ Square the two sides to cancel the square root
∴ ([tex]\sqrt{a-b+c}[/tex])² = (3)²
∴ a - b + c = 9
→ Add b to both sides to move b from the left side to the right side
∴ a - b + b + c = 9 + b
∴ a + c = 9 + b
→ Subtract c from both sides to move c from the left side to the right side
∴ a + c - c = 9 + b - c
∴ a = 9 + b - c

Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is T=50+n-40/4, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If T=57°F, find the number of chirps per minute.
Answers
Answer:
Number of chirps per minute = 68
Step-by-step explanation:
Given:
T = 50+ (N - 40)/4
where,
T is a temperature in degrees Fahrenheit
N is a number of chirps per minute
Find n when T = 57°F
T = 50 + (N - 40)/4
57 = 50 + (N - 40)/4
57 - 50 = (N - 40)/4
7 = (N - 40)/4
Multiply both sides by 4
7 × 4 = (N - 40)/4 × 4
28 = N - 40
28 + 40 = N
68 = N
N = 68
Number of chirps per minute = 68

The graph starts at -2 with a solid (colored in) point on the -2. So there are no y's less than -2 on the graph.
The graph continues to go up. Yes, it goes to the right, but we are looking at the y's. There is an arrow at the right end of the graph which means it continues to go up forever.

LN is a secant. It cuts the circle's circumference in two places.
TP is an arc. It is related to the the two givens by
(Large Arc - Small Arc )/2 = the exterior angle
We are looking for the large arc. Call it x
Small arc = 50
Exterior angle = 34
(x - 50)/2 = 34 Multiply both sides by 2
x - 50 = 2 *34
x - 50 = 68 Add 50 to both sides.
x = 68 + 50
x = 118
So the arc labeled TP = 118
Answer: TP = 118

Which relationships describe angles 1 and 2?
Select each correct answer.
adjacent angles
vertical angles
complementary angles
supplementary angles
Answers
Answer: Complementary angles, adjacent angles
Step-by-step explanation:
Because of vertical angles, we know that the sum of angles 1 and 2 would be equal to 90 degrees, as the measure of right anglese is 90 degrees.
A pair of angles that sum to 90 degrees are otherwise called complementary angles.
These pair of angles are also adjacent because they have a common side/vertex yet do not intersect.
They are not vertical angles because they are not opopsite of each other.
They are not supplementary angles because they don't sum to 180 degrees.
