Step-by-step explanation:
Answer:
b+3(3-2b)=1-2(b+1)
One solution was found :
b = 10/3 = 3.333
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
b+3*(3-2*b)-(1-2*(b+1))=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(b+(3•(3-2b)))-(1-2•(b+1)) = 0
Step 2 :
Equation at the end of step 2 :
(b + 3 • (3 - 2b)) - (-2b - 1) = 0
Step 3 :
Equation at the end of step 3 :
10 - 3b = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : -3b+10 = 0
Subtract 10 from both sides of the equation :
-3b = -10
Multiply both sides of the equation by (-1) : 3b = 10
Divide both sides of the equation by 3:
b = 10/3 = 3.333
One solution was found :
b = 10/3 = 3.333

Answer: 4) 8
Step-by-step explanation:
-80/10=-8
-8 = - 8. - No
80/-10= - 8. - 8=-8 - No
-(80/10)=-(8)=-8. - 8=-8 - No
8 - Yes.
First you have to add all four of your numbers, 8.6+14.2+ -3.7+ 12=31.1. Then you divide your answer by 4, the number of numbers you added, and you get your answer of 7.775.
Answer:
1. 1 point
2. The x-coordinate of the solution = 2/17
3. The y-coordinate of the solution = -16/17
Step-by-step explanation:
Given that the equation is of the form;
y = -2³×x and y = 9·x - 2, we have;
y = -8·x and y = 9·x - 2
1. Given that the two lines are straight lines, the number of points of intersection is one.
2. The x-coordinate of the solution
To find a solution to the system of equations, we equate both expression of the functions and solve for the independent variable x as follows;
-8·x = 9·x - 2
-8·x - 9·x= - 2
-17·x = -2
x = 2/17
The x-coordinate of the solution = 2/17
3. The y-coordinate of the solution
y = 9·x - 2 = 9×2/17 - 2 = -16/17
y = -16/17
The y-coordinate of the solution = -16/17.
