b) Use the graph to estimate the
value of x when y = 1



Answers

a) The graph of y = 4x - 1 is shown in attached image.

b) By using the graph at y = 1 the value of x is 1/2.

What is Linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The function is,

y = 4x - 1

Now, The graph of function y = 4x - 1 is shown in image.

And, At y = 1;

By the graph the value of x = 1/2.

And, In mathematically;

At y = 1

The value of x is;

y = 4x - 1

1 = 4x - 1

4x = 2

x = 2/4

x = 1/2

Thus,

a) The graph of y = 4x - 1 is shown in attached image.

b) By using the graph at y = 1 the value of x is 1/2.

L is in the interior of ∠JKM. If m∠JKL=56.4° and m∠JKM=82.5°, what is m∠LKM?

Answers

m∠LKM = 26.1°

Ffkdkdkkddkd

The measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees

The point where two lines meet or intersect is known as an angle.

If L is in the interior of ∠JKM, then:

∠JKL + ∠LKM = ∠JKM

Given the following parameters

m∠JKL=56.4° and m∠JKM=82.5°

Required angle

m∠LKM

From the expression above:

m∠LKM = ∠JKM - ∠JKL

m∠LKM = 82.5 - 56.4

m∠LKM  = 26.1 degrees

Hence the measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees

A six-sided die is rolled. What is the probability of landing on a number less than 3? Put our answer in simplest form.

Answers

Answer:

1/3

Step-by-step explanation:

2/6

1/3

Answer:

Probability of any one face to turn up is 1/6,

The probability of any above 3 is 3/6,

The probability of even number is also 3/6

So the probability of either above three or even outcome is 1/6(3/6 + 3/6)=1/6, since both events are independent of the any face event and both events are mutually exclusive.

NB:If the two events are not mutually exclusive, then

P(A) is the total event, P(B) the probability of any face above 3 and P(C) probability of any face an even number, then the Bayesian prediction formula is P(B|C) the probability of the event B occuring while C occurs is equal to (PC|P(B))/(P(B)+P(C), where P(C|B) is probability of C occuring at B.

So P(B|C)=(1/3 * 1/3)/(1/3 + 1/3) =(1/9)/(2/3) = 3/18= 1/6.
