Prolly not the best person to answer this question lol
-12+3b-1=-5-b
Combine like terms to get:
3b-13=-5-b
Add 13 to both sides:
3b= 8-b
Add b to both sides:
4b=8
Divide both sides by 4:
4b/4=8/4
b=2
Final answer
b=2
Answer:
The required system of equations to the given parametric equations are:
5x1 - x2 = 6
x1 + x2 = -6
Step-by-step explanation:
Given the parametric equations:
x1 = t
x2 = -6 + 5t
Eliminating the parameter t, we obtain one of the equations of a system in two variables, x1 and x2 that has the solution set given by the parametric equations.
Doing that, we have:
5x1 - x2 = 6
Again a second equation can be a linear combination of x1 and x2
x1 + x2 = -6 + 6t
x1 + x2 = -6 (putting t=0)
And they are the required equations.
Answer:
A
Step-by-step explanation:
Because 7000*1.09= 7630
and 5000*1.11= 5550 which are both equal to the amount each account will have after one year where they have gained interest.
In the first account 7630-7000=630 and the second 5550-5000=550
which is how much each gained in interest. together that makes 630+550=1180 in interest.
