How do I do this im having trouble and its my exam day?
Gnom [1K]

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

Hope this helps :)

In which funtion is x=2 mapped to 32?
prisoha [69]

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.

Find the value of two numbers if their sum is 23 and their difference is 3.
Yakvenalex [24]

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
