y=-4-x
y=2x-1
-4-x=2x-1
3x=-3
x=-1
y=-3
The type of equation is consistent because they intersect at ( -1,-3 )
Answer:
13
Step-by-step explanation:
Explanation:
Use the absolute value definition to rewrite the absolute value equation as two separate equations.
k-10=3
k-10=-3
Solve the equation for k
k=13
k-10=-3
k=13
k=7
The equation has 2 solutions, meaning k1=7,k2=13. Which gives you the answer of: 13 (K1=7,k2=13)
Answer:
4262
Step-by-step explanation:
2 + 7x^2- 2x^3-8x +7x^4 at x = 5
= 2 + 7*(5)^2 - 2*(5)^3-8*5 +7*(5)^4
=2+175-250-40+4375
=4552-290
=4262
The student went wrong in step three. the solutions should have been -3 and 5
