Which of the following is the equation of a line perpendicular to the line y =

makvit [3.9K]

Answer:

y = $\frac{1}{10}$ x + $\frac{13}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 10x + 1 ← is in slope- intercept form

with slope m = - 10

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-10}$ = $\frac{1}{10}$ , thus

y = $\frac{1}{10}$ x + c ← is the partial equation

To find c substitute (5, 7) into the partial equation

7 = $\frac{1}{2}$ + c ⇒ c = 7 - $\frac{1}{2}$ = $\frac{13}{2}$

y = $\frac{1}{10}$ x + $\frac{13}{2}$ ← equation of line

If p is the hypothesis of a conditional statement and q is the conclusion, which is represented by ~p → ~q?

AfilCa [17]

Conditional statement is a statement with a hypotesis and a conclusion:

If $\text{ \underline{ hypothesis } } p$ , then $\text{ \underline { conclusion } } q$ or mathematically $p\rightarrow q$ .

Converse statement of $p\rightarrow q$ is statement $q\rightarrow p$ .

If you negate (that means stick a "not" in front of) both the hypothesis and conclusion, you get the inverse: $\neg p\rightarrow \neg q$ .

Finally, if you negate everything and flip p and q (taking the inverse of the converse) then you get the contrapositive: $\neg q\rightarrow \neg p$ .

Then,

Answer: the correct choice is D (the inverse of the original conditional statement).

What is the answer ?

Ugo [173]

The tip is $15.73. I get that by multiplying 78.63 and .20. then you add the tip to the bill and get $94.36. you then find the discount by multiplying 94.36 and .15. the discount is 14.15. then subtract 14.15 from 94.36 to get your total.

the answer is $80.21

What is the modulus of 5 - 3i

DaniilM [7]

Hello!

The above expression exemplifies a “complex number.” A complex number takes the following form:

a + bi

In this case, A is equal to (5) while B is equal to (-3). To find the modulus of a complex number, we will need to use the following formula (let “x” represent the modulus):

x = √(a² + b²)

Insert any known values into the formula above:

x = √((5)² + (-3)²)

Simplify the right side of the equation:

x = √(25 + 9)
x = √34

We have now proven that the modulus is equal to √34.

I hope this helps!
