1. Resolva as seguintes equações do 1o grau: a) 5x + x – 40 = 5 – x
b) 20 + 6x = -2x + 26
c) 3,5x + 1 = 3 + 3,1x
d) 7p + 15 – 5p 10 = - 17 + 13p
e) 13y – 5 = 11 + 9y
f) 9t – 14 = 7t + 20
g) 5 – a – 11 = 4a – 22
h) 2y + 21 – 6y = - 12 + y – 7

POR FAVOR COM CANTAS...!

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!

you est gay to much man grow some bollas also man kcuf off you little harry p u s s y. stupid

there is no answer sorry!

step-by-step explanation:

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
