Answer:
ab² - b = b(ab -1)
Step-by-step explanation:
The variable b is common to both terms here. Thus,
ab² - b = b(ab -1)
The measure of angle A in the triangle is 18°
<h3>How to determine the measure of angle A?</h3>
The angles in the triangle are given as:
m∠A = (2x − 24)°, m∠B = (x + 8)°, m∠C = (4x + 49)°
The sum of angles in a triangle is 180
So, we have
m∠A + m∠B + m∠C = 180
Substitute the known values in the above equation
So, we have:
2x − 24 + x + 8 + 4x + 49 = 180
Evaluate the like terms
7x = 147
Divide both sides by 7
x = 21
Substitute x = 21 in m∠A = (2x − 24)°
m∠A = (2 * 21 − 24)°
Evaluate
m∠A = 18°
Hence, the measure of angle A in the triangle is 18°

Answer:
x is left to right y is up and down !!
Step-by-step explanation:
x is left to right y is up and down !! x would be (0,-1) and (0,-3)
Make x the subject means you need to solve for x
y = ax^2 solve for x
divide both side by a
y/a = ax^2/a
simplify
y/a = x^2
so
x = square root (y/a)
