Answer:
m∡BCA = 57°
Step-by-step explanation:
find 'x' by adding all expressions and setting them equal to 360°
9x+1 + tx+12 + 10x-37 = 360
24x = 384
x = 16
Substitute 16 into 10x-37
160 - 37 = 123
m∡BCA is supplemental with 123°, therefore it measures 57°
The pair of rational numbers with their sum are matched.
<h3 /><h3>What is rational number?</h3>
The numbers in the form of p/q is called the rational number.
1. -2/a²b +2/ab² = ( -2ab² +2a²b) / a³b³
= 2(a-b)/a²b²
2. 1/2ab -1/4a²b² =( 4a²b² -2ab) / 8a³b³
= 2ab -1 /4a²b²
3. 2/a²b³ -2/ab = (2ab -2a²b³) / a³b⁴
= 2( 1- ab²) /a²b³
4. 1/ab³ -1/a²b = a²b - ab³ / a³b⁴
= (a - b²) / a²b³
Thus, all the rational numbers are matched with their sum.

Answer:
Translation of h(x) is 2 unit down, 3 unit right and vertical stretch by 2
Step-by-step explanation:
Given function: 
Parent function: 
It is parabolic function.

Shift 2 unit down


Shift 3 unit right


Vertical stretch by factor 2


So, Translation of h(x) is 2 unit down, 3 unit right and vertical stretch by 2
