<span>A) Y= -5x+3
B) -x -7y = 13 substituting equation A) into B)
B) -x -7*(-5x +3) = 13
</span>
<span>B) -x +35x -21 = 13
B) 34x = 34
x = 1

<span>A) Y= -5*1 +3
A) Y= -2

As you can see, in the table of the first function, f(2) = 18, and in the table of the second function g(2) = 18. Then, for x = 2, f(x) = g(x). and x =2 is the solution of the equation.
Answer: x = 2.
Answer: a0 =$97.5 ; a1 =$87.96 ; a2=$282.48; a3=$1,722.5
; a4=$1,553.96
; a5=$4,990.48
Step-by-step explanation:
Hi, to solve this problem we have to multiply each total by the commission in decimal form (6 / 100= 0.06).
So:
$1625 x 0.06 = $97.5
$1,466 x 0.06 =$87.96
$4,708 x 0.06 =$282.48
And finally, to obtain the total costs we have to add to each total the commission of the total.
$1625 + $97.5 = $1,722.5
$1,466 +$87.96 = $1,553.96
$4,708 +$282.48 = $4,990.48
Feel free to ask for more if it´s necessary or if you did not understand something.
Answer:2x+30 =90
If the angle is 90° altogether
60=A 30=30
Step-by-step explanation:
2x+30 =90
-30 -30
2x=60
÷2. ÷2
x=30
2*30=60
60+30=90
60=A B=30
2.25h(60m/hr)(1/3)=45m
