Which equation has a slope of 1/2 and passes through the point (1.2)?

Answer:

The answer is

<h2>x - 2y + 3 = 0</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of a line given a point and slope we use the formula

y - y1 = m(x - x1)

where

m is the slope

( x1 , y1) is the point

From the question the point is ( 1 , 2) and the slope is 1/2

Substitute the values into the above formula and solve for the equation

That's

<h3>y - 2 =  \frac{1}{2} (x - 1) \\ 2y - 4 = x - 1 \\ x - 2y - 1 + 4 = 0</h3>

We have the final answer as

<h3>x  - 2y + 3 = 0</h3>

Hope this helps you

<h3>Answers:</h3>
  • A. T <-> U  is a <u>biconditional</u>
  • B. (A & B) v (C & D)  is a <u>disjunction</u>
  • C. R -> ~S  is a <u>conditional</u>
  • D. P & Q   is a <u>conjunction</u>
  • E. ~(R v P)  is a <u>negation</u>

========================================

Explanations:

  • A biconditional is anything in the form A <-> B. This is a compact way of saying (A -> B) & (B -> A). We replace A and B with logical statements.
  • Disjunctions are of the basic form A v B. The "v" basically means "or".
  • Any conditional is of the form "if... then...". For example, "if it rains, then it gets wet outside" is a conditional. In terms of logic symbols, we write A -> B to mean "if A, then B".
  • Conjunctions are whenever we combine two logical statements with an "and" or an ampersand symbol. The basic form is A & B
  • Negations are the complete opposite of the original. If the original is P, then the negation is ~P, which is read as "not P".

Which is the range of the function f(x) = (9)×?
Anna [14]

Using it's concept, it is found that the range of the function f(x) = 9^x is given by:

all real numbers greater than 0.

<h3>What is the range of a function?</h3>

It is the set that contains all possible output values for the function.

In this problem, the function is:

f(x) = 9^x

For <u>exponential functions without vertical shifts</u>, as is the case in this problem, the range is given by:

all real numbers greater than 0.
