Find inverse of f(x)=3x+1

Answers

$f(x)=3x+1\to y=3x+1\n\n3x+1=y\ \ \ \ \ |-1\ both\ sides\n\n3x=y-1\ \ \ \ \ |:3\ both\ sides\n\nx=(1)/(3)y-(1)/(3)\n\nAnswer:f(x)=(1)/(3)x-(1)/(3)$

f:R->R, f(x) = 3x+1;Let be g the inverse of f;3x+1 = y => 3x = y-1 => x = (y-1)/3;g:R->R, g(y) = (y-1)/3;

2sin²(x)-5cos(x)+1=0

Answers

Remember the basic trig identity

$\sin^2 x + \cos^2 x = 1$

We can move the cosine term to the right side to get

$\sin^2 x = 1 - \cos^2 x$

We can then replace $\sin^2 x$ in the original equation and basically factor the resulting equation like a quadratic:

$2(1 - \cos^2 x) - 5 \cos x + 1 = 0$
$(2 - 2 \cos^2 x) - 5 \cos x + 1 = 0$
${-2} \cos^2 x - 5 \cos x + 3 = 0$
$2 \cos^2 x + 5 \cos x - 3 = 0$
$(2 \cos x - 1)(\cos x + 3) = 0$

Then, we can see that $\cos x$ either equals $(1)/(2)$ or $-3$ . But since the range of cosine is only from $[-1, 1]$ , cosine can't equal $-3$ at all! So, you just have to solve for x when $\cos x = (1)/(2)$ , which is when

$x = \{ (\pi)/(3), (5\pi)/(3) \} + 2 \pi k | k \in \mathbb{Z}$
(The last part of the solution says that k can be any integer.)

If you only want solutions in the range $[0, 2\pi)$ , then your answer is just

$x = (\pi)/(3), (5\pi)/(3)$

Classify the expression: 5x + 2.Linear expression
Quadratic expression
Cubic expression
Quartic expression

Answers

Answer:it is a linear expression

Step-by-step explanation:

Linear expressions or equations are expressions in which the highest power of the variable is one.

Quadratic expressions or equations are expressions in which the highest power of the variable is two.

Cubic expressions or equations are expressions in which the highest power of the variable is three.

Quartic expressions or equations are expressions in which the highest power of the variable is four.

From the expression, 5x + 2 given,

the highest power of x is one. So it is a linear expression.

It is Linear expression

Sandra wants 1/6 of the fruit in her fruit baskets to be bananas. If the greatest number of fruit that will fit in each basket is 24 what fraction can represent the possible ways Sandra can have the bananas in the fruit baskets? Explain your answer.

Answers

If the total capacity of the basket is 24 to find 1/6 you divide 24 by 6 and get 4. 4 is equal to 1/6 of 24 which means Sandra can only bring 4 bananas.
