Answer:
h=3in
Step-by-step explanation:
A=a+b
2h
Solving forh
h=2A
a+b=2·13.5
3+6=3in
Answer:
9765625
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
r = 25 ÷ 5 = 125 ÷ 25 = 5
This indicates the sequence is geometric with n th term
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 5 and r = 5 , then
a₁₀ = 5 ×
= 5 × 1953125 = 9765625
5x+17+15=45
5x=45-17-15
5x=13
x=13/5
Answer:
3x +8y = -17
Step-by-step explanation:
The point-slope equation is a good place to start.
y -k = m(x -h) . . . . . equation through (h, k) with slope m
Filling in your numbers gives ...
y +4 = -3/8(x -5)
Multiplying by 8, we get
8y + 32 = -3x + 15
Adding 3x-32 puts this in standard form.
3x + 8y = -17
_____
Standard form is ...
ax +by = c
where a, b, c are mutually-prime integers and the leading coefficient is positive. (If a=0, the leading coefficient is b.)
