Answer:
2.5
Step-by-step explanation:
The equation will have infinite solutions when it is a tautology--when both sides say exactly the same thing.
Eliminate parentheses, match coefficients, and solve for b.
ax +ab = 4x +10
a = 4 . . . . . . coefficient of x
ab = 10 . . . . constant
Since we know a, we can find b:
4b = 10
b = 10/4 . . . . . . . divide by 4
b = 5/2 = 2.5 . . .express in your favorite form

Answer:
(d) a1 = 11
Step-by-step explanation:
Put the numbers in the given formula and solve for a1.
a5 = 176 = a1(r^(5-1)) = a1·r^4
a7 = 704 = a1(r^(7-1)) = a1·r^6
Dividing a7 by a5 gives ...
a7/a5 = (a1·r^6)/(a1·r^4) = r^2 = 704/176 = 4
Then a1 is ...
a1 = a5/(r^4) = 176/(r²)² = 176/(4²) = 11
The first term is 11.
