Solution :

★ a - 2b + ab .........(Given equation)

  • Now, it is given that a = 3 and b = -1 by putting the values of a and b in given equation we get :]

➨ 3 - 2(-1) + (3)(-1)

➨ 3 + 2 - 3

<h2>Here, </h2>

a = 3

b = -1

Then,

<h3>a - 2b + ab \\  = 3 - 2 \times ( - 1) + 3 \times ( - 1) \\  = 3 + 2 - 3 \\  = 5 - 3 \\  ⟶2</h3>

uysha [10]

f(x)= \frac{\frac{\sin{x}}{\cos{x}}+\frac{\cos{x}}{\sin{x}}}{3\sec{x}}

\frac{\frac{\sin{x}}{\cos{x}}+\frac{\cos{x}}{\sin{x}}}{3\sec{x}} \implies \\ \frac{\sin^2{x}+\cos^2{x}}{\sin{x}\cos{x}}\frac{\cos{x}}{3}\implies \\\frac{1}{\sin{x}\cos{x}}*\frac{\cos{x}}{3}\implies \\ \frac{1}{3\sin{x}}

So,

\lim_{x \rightarrow \frac{3\pi}{2}}{f(x)=f(\frac{3\pi}{2})=\frac{1}{3\sin{\frac{3\pi}{2}}}=-\frac{1}{3}

A bat and a ball cost $1.10. The bat is $1 more than the ball. What does the ball cost?
mestny [16]
1.05 is the answer
Write an algebraic equation to solve
a= ball
b= bat
a + b = 1.10
Write out the equation for the ball (a = b + 1)
substitute the equation for the ball into the original equation
(b + 1) + b = 1.10
simplify the equation
2b + 1 = 1.10
Solve the equation
2b + 1 = 1.10
-1. -1
——————-
2b .1
/2 /2 = .05

Plug in your answer into the equation for the ball (a= b + 1)
a= .05 + 1
1.05 is your answer
