Answer:
x = 4
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
2.5
Step-by-step explanation:
The average rate of the function f(x) from x=a to x=b is given by:
From the question, the exponential function goes through (0,30) and (20,80).
This implies that f(0)=30 and f(20)=80
Therefore the average rate of change from x = 0 to x = 20 is
The second choice is correct
The answer is y-3=1/2(x-1)
X^2 - 3x + p = 0
x^2 + qx + 7 = 0
αβ = p..........................(1)
3α + 3β = -q..................(2)
3α3β = 9αβ = 7
so substituting for αβ from (1):-
9p = 7
p = 7/9
α + β = 3 ( from first equation)
from (2) -q = 3 (α + β)
so -q = 3*3 = 9 and q = -9
Answer is p = 7/9 and q = -9
6,600 x 7.5% = $495
$495 + 6,600 = 7,095
$495 increase in dollars
$7,095 was in his account at the end of the last year
Hope this helps! =)
