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

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

Step-by-step explanation:
Since you need to find the y value when x = -1, go to -1 on the x axis, and find where the green line crosses. The green line goes through the point (-1,3), or one box to the left and three boxes up, so the y value is 3.
Hopefully this helps- let me know if you have any questions!
Answer:Find the point in which the x = 1, and the y point meets.
When x = 1, y = 2

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

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.
