Answer:
x = 1
Step-by-step explanation:
The approximate solutions to f(x) = g(x) is where the two graphs intersect. It appears the meet at just past x=1 and around x=-2.5
The questions asks for an approximate solution, so it is only asking for one of the solutions.
Answer:
1.Solve the system of equations.
y = 2x^2 - 3
y = 3x - 1
a. no solution
b. (-1/2, 5), (2, -5/2)
c. (-1/2, -5/2), (2,5)
d. (1/2, 5/2), (2, 5)
2.how many real number solutions does the equation have 0 = -3x^2 + x - 4
a. 0
b. 1
c. 2
d. 3
3. solve the equation by completing the square. If necessary round to the nearest hundredth.
x^2 - 18x = 19
a. 1; 19
b. -1; 19
c. 3; 6
d. -3; 1
4. solve. x^2 - 81 = 0
a. 0
b. -9
c. -9, 9
d. 9
5. which model is most appropriate for the data shown in the graph below? (need wedsite to know the problem)
a. quadratic
Answer:
b is 7 units from 0.
Step-by-step explanation:
= 7 means that the absolute value of b is 7. This means that b can be -7 or 7, so it will always be 7 units from 0.
Hope this helps!
Answer:
x = 1
y = 4
Step-by-step explanation:
9x + 5y = 29 eqn 1
3x + y = 7 eqn 2
Using the method of substitution,
"substituting y"
multiplying through eqn 2 by -5
-15x - 5y = -35 eqn 2
9x + 5y =29 eqn 1
adding eqn 1 and eqn 2
-6x = -6
x = 1
3x + y = 7
3 (1) + y = 7
3 + y = 7
y = 7 - 3
y = 4
