Answer:
1683 / 383 = 4.39 or approx 4.4
Answer:
7, -7
Step-by-step explanation:
x^2-6.5= 42.5 add 6.5 to both sides
x^2= 49
The square root of 49 is 7 and -7.
Answer:
(1 , 1)
Step-by-step explanation:
Given in the question two equations
Equation 1
y = x² – x + 1
Equation 2
y = x
Equate both equations
x² – x + 1 = x
0 = x² – x + 1 - x
x² – 2x + 1 = 0
x² - x - x + 1 = 0
x(x - 1) -1(x - 1) = 0
(x - 1)(x - 1) = 0
(x-1)² = 0
x - 1 = 0
x = 1
Plug x = 1 in first equation
y = 1² – 1 + 1
y = 1
3/4 * h = 2 1/4
3/4* h * 4/3 = 9/4 * 4/3
h = 3
