Answer:
The answer is C. {(5,0), (-8,-5)}
Step-by-step explanation:
Answer 8.17
Step-by-step explanation:
1.divide 98 by twelve, since there are 12 inches in a foot
98 \ 12
2.then round to the nearest tenth. 8.16 is rounded to 8.17
Not a 100% positive this is the answer but i think it is 2.5
got this by dividing 30 by 12 and got 2.5
Answer:
Options (2), (4) and (6)
Step-by-step explanation:
Given system of equations is,
f(x) = x² - 5x + 7
g(x) = 2x + 1
By equating both the functions,
f(x) = g(x)
x²- 5x + 7 = 2x + 1
x² - 5x - 2x + 7 - 1 = 0
x² - 7x + 6 = 0
x² - 6x - x + 6 = 0
x(x - 6) - 1(x - 6) = 0
(x - 1)(x - 6) = 0
x = 1, 6
For x = 1,
g(x) = 2x + 1
g(1) = 2(1) + 1
= 3
For x = 6,
g(6) = 2(6) + 1
= 13
Common points (solutions) of both the functions 'f' and 'g' are (1, 3) and (6, 13).
Both the solutions lie in quadrant 1.
x-coordinate of the solution (1, 3) is x = 1.
y-coordinate of the solution (1, 3) is y = 3.
Therefore, options (2), (4) and (6) are the correct options.
