Answer:
y = -3x - 27
Step-by-step explanation:
0 = -3[-9] + b
-27 = b
y = -3x - 27

A+s=496
s=496-a
and we are also told that:
s=3a
Since s=s we can say:
3a=496-a add a to both sides
4a=496 divide both sides by 4
a=124
So 124 adult tickets were sold.

Opposite Leg of <em>x</em> = 12
Adjacent Leg of <em>x</em> = 15
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [tangent]: sinx° = 12/15
- Trig inverse: x° = sin⁻¹(12/15)
- Evaluate: x = 53.1301°
- Round: x ≈ 53°
Answer: length = 12
<u>Step-by-step explanation:</u>
Use Pythagorean Theorem: length² + height² = hypotenuse²
length = L
height = L - 7
hypotenuse = L + 1
L² + (L - 7)² = (L + 1)²
L² + L² - 14L + 49 = L² + 2L + 1
2L² - 14L + 49 = L² + 2L + 1
L² - 14L + 49 = 2L + 1
L² - 16L + 49 = 1
L² - 16L + 48 = 0
(L - 4)(L - 12) = 0
L - 4 = 0 L - 12 = 0
L = 4 L = 12
Input L = 4 and L = 12 to find the height:
Height = L - 7 height = L - 7
= 4 - 7 = 12 - 7
= -3 = 5
↓
negative height is not valid
So, the only valid solution is L = 12
Answer:
D
Step-by-step explanation:
Accuracy refers to how close measurements are to the "true" value (which is the target in this case), while precision refers to how close measurements are to each other.
Since the arrows fall away from the bullseye and are spread out I would classify this as low accuracy and low precision.
