You would be 73. 400-(your age*3)=181
Answer:
x ≤ a → x ∈ (-∞, a]
x < a → x ∈ (-∞, a)
x ≥ a → x ∈ [a, ∞)
x < a → x ∈ (a, ∞)
--------------------------------------
Therefore:
x ≥ 7.8 → [7.8, ∞)
x < 7.8 → (-∞, 7.8)
x ≤ 7.8 → (-∞, 7.8]
x > 7.8 → (7.8, ∞)

Step-by-step explanation:
Answer:
C. x - y = 0
Step-by-step explanation:
First find write the equation in slope-intercept form, then rewrite to convert to standard form as Ax + By = C.
Equation in Slope-intercept form:
Find m and b
m = rise/run = 1/1 = 1
b = y-intercept = 0 (where the line intercepts the y-axis)
Substitute m = 1, and b = 0 into y = mx + b
Thus:
y = (1)(x) + 0
y = x
Rewrite to convert to standard form.
Thus, the equation in standard form would be:
x - y = 0
To find the hypotenuse of any right triangle, you need to square and add the other two sides. We call those two sides LEGS.
(legs)^2 + (leg)^2 = (hypotenuse)^2
In your textbook, you will see it this way:
a^2 + b^2 = c^2, where a = b = legs.
