Answer:
y = -⅓x - 5
Step-by-step explanation:
the slope of g(x) = 3
=> the slope of the line perpendicular
to g(x) = -1 /3
so,
the line is :
y +5 = -⅓(x-0)
y = -⅓x - 5
Answer:
The answer is B.
Step-by-step explanation:
You have to use area of trapezoid formula, A = 1/2×(a+b)×h where a, b are the side lengths and h is height :
Answer:
Lacy is 16 years old, and Jack is 32 years old.
Step-by-step explanation:
Lacy's age now is L.
Jack's age now is twice Lacy's age, so Jack's age now is 2L.
In 3 years, Lacy's age will be L + 3, and Jack's age will be 2L + 3.
In 3 years, the sum of their ages will be L + 3 + 2L + 3, and it will equal 54.
L + 3 + 2L + 3 = 54
3L + 6 = 54
3L = 48
L = 16
Lacy is 16 years old.
Jack's age is 2L.
2L = 2(16) = 32
Jack is 32 years old.
