Answer:
x = 0.19 or x = -0.76
Step-by-step explanation:
Equation: 7²-4x = 2
reordering the equation,
7x²-4x-2 = 0
Applying,
x = [-b±√(b²-4ac)]/2a..................... Equation 1
From the question,
Given: a = 7, b = -4, c = -2
Substitute these values into equation 1
x = [-4±√(-4²-(2×7×-2)]/(2×7)
x = [-4±√(16+28)]/14
x = (-4±√44)/14
Either
x = (-4+√44)/14
x = (-4+6.63)/14
x = 2.63/14
x = 0.19
or
x = (-4-√44)/14
x = (-4-6.63)/14
x = -10.63/14
x = -0.76
Answer:
In order to ride on the ride an individual must be at least 4 feet tall.
This means that the individual must be equal to 4 ¾ feet tall.
h = 4 ⅓
and the individual could be greater than 4¾ feet tall.
h > 4 ¾
So the individual could be greater than and equal to 4¾ feet tall.
h ≥ 4¾
It would be 80 because 2 times 120 is 240. 240 divided by 3 is 80

Answer:
slope is -2/5
Step-by-step explanation:
m=y2-y1/x2-x1
m=3-5/2-(-3))
m=-2/2+3
m=-2/5
