I think the answer is D
Answer: D
Step-by-step explanation:
Given that Svana wants to solve the equation 1/2x - 1.0675 = 3x - 4145.
This equation is a system of equations which can be solved by using simultaneous equation methods.
But if she uses a graphing program to graph the equations y = 1/2x - 1.0675 and y = 3x - 4.145
The solution of 1/2x - 1.0675 = 3x - 4.145. Will be the point of intersection of the two equation.
Trace the point of intersection to the x - axis and also to the y - axis.
The solution to the system of equations is ( 1.231, - 0.452 )
Answer:
See below.
Step-by-step explanation:
1. h
2. g
3. a
4. f
5. c
6. b
7. e
8. (17 * 5) * 2 = 17 * (5 * 2) = 17 * 10 = 170
9. 700 + 137 + 300 = 700 + 300 + 137 = 1137
10. $0.25 + $2.69 + $4.75 = $0.25 + $4.75 + $2.69 = $7.69
11. -8 + 57 + 18 = 18 - 8 + 57 = 10 + 57 = 67
12. 26 + 19 + 14 = 20 + 6 + 19 + 10 + 4 =
= 20 + 10 + 6 + 4 + 19
= 30 + 10 + 10
= 40 + 19
= 59
Answer:
x = 3
y = 0
Step-by-step explanation:
The method of substitution is when one solves an equation for one of the variables, and then substitutes the expression into the other equation. After doing so, one will solve the other equation for the remaining variable and then backsolve for the first variable.
4x + 2y = 12
x = y + 3
The second equation is already sovled for parameter (x), subttiute this into the other equation,
4(y + 3) + 2y = 12
Distribute,
4y + 12 + 2y = 12
Simplify,
6y + 12 = 12
Inverse operations,
6y + 12 = 12
-12
6y = 0
/6
y = 0
Backsolve for (x), substitute the value of (y) into the equation for (x) and solve,
x = y + 3
x = 0 + 3
x = 3
Answer:
Answer is h(0)=1
Step-by-step explanation:
All you have to do is substitute x with 0 in the original equation.
