Answer:
C.
Step-by-step explanation:
So basically set (10x-13) equal to (3x+22) and then solve for x
x=5
Plug 5 into the equations
(10(5)-13)=37
(3(5)+22)=37
These two angles are congruent due to the triangle being isosceles
37+37=74
All angles in a triangle are equal to 180 degrees
Therefore 180-74=106
Angle JKL= 106 degrees

The function g(x)=4(x+3)² - 68 is mapped to 32.
<h3>What is equation?</h3>
An equation is a mathematical expression in terms of one or more unknown variable.
Given are the following functions:
f(x)= - 3x² - 4
g(x)= 4(x+3)²-68
f(x)= 3x
f(x)= 2x-62
To get the mapped function, we substitute the value of x in all function,
a) f(x)=-3x²- 4
Put x=2,
f(2)= -3 (2)² - 4
f(2)= -16
It is not mapped.
b) g(x)=4(x+3)² - 68
Put x=2,
g(2) = 4(2+3)² - 68
g(x) =32
It is mapped to 32.
c) f(x)=3x
Put x=2,
f(2) = 3 x 2 =6
It is not mapped.
d) f(x)=2x - 62
Put x=2,
f(2) =2x2 -62
f(2) = -58
It is not mapped.
Therefore, the function g(x)=4(x+3)² - 68 is mapped to 32.

Answer:
x=1,y=-1
Step-by-step explanation:
the ans is 1 and -1.
x+y=23
x-y=5
First, add the equations.
2x=28
x=14
Then...
14+y=23
y=9
Therefore the answer is...
x=14 y=9
