Answer:
Here both line are perpendicular because as product of slope of both lines is -1
Answer:
lines are perpendicular
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(1)
y = [tex]\frac{3}{4}[/tex] x - 1 ← is in slope- intercept form
with slope m = [tex]\frac{3}{4}[/tex]
(2)
3y = - 4x + 6 ( divide each term by 3 )
y = - [tex]\frac{4}{3}[/tex] x + 2 ← in slope- intercept form
with slope m = - [tex]\frac{4}{3}[/tex]
Then
[tex]\frac{3}{4}[/tex] × - [tex]\frac{4}{3}[/tex] = - 1
Thus the 2 lines are perpendicular to each other

Answers
Step-by-step explanation:
Using the following property of logarithms,
[tex]\ln{\left(\dfrac{a}{b}\right)} = \ln{a} - \ln{b}[/tex]
we can write the given equation as
[tex]\ln{(x^2 + 1)} - \ln{(x^2 - 1)} = \ln{\left(\dfrac{x^2 + 1}{x^2 - 1}\right)}[/tex]
[tex]\:\:\:\:\:\:\:\:\:= \ln{\dfrac{x(x + 1)}{x(x - 1)}} = \ln{\left(\dfrac{x + 1}{x - 1}\right)}[/tex]
But recall that [tex]\ln{e} = 1[/tex] so we can write our original equation as
[tex]\ln{\left(\dfrac{x + 1}{x - 1}\right)} = \ln{e}[/tex]
or simply
[tex]\dfrac{x + 1}{x - 1} = e[/tex]
Multiplying both sides by [tex](x - 1),[/tex] we get
[tex]x + 1 = e(x - 1)[/tex]
Solving for x, we get
[tex]x = \dfrac{e + 1}{e - 1}[/tex]

The quotient of a number and -7, decreased by 2, is 10
Answers
Answer:
Let the required number be x
The quotient of a number and -7, decreased by 2, is 10
According to the above problem, we get
[tex] \frac{x}{( -7)} - 2 = 10 \\ \frac{x}{( - 7)} = 10 + 2 \\ \frac{x}{( - 7)} = 12 \\ x = ( - 7) \times 12 \\ \boxed{x = - 84}[/tex]
Therefore, the required number is -84.

Answers
Answer:
$10.17
Step-by-step explanation:
Mean simply is defined as "average", so the average price of a hamburger across five resturaunts is found by adding all of the prices together and then dividing by the number of prices there are.
9.95 + 12.95 + 8.50 + 8.95 + 10.50 = 50.85 dollars, which then you divide by 5, and end up with the solution: $10.17

Given:
The given statement is "if [tex]a=42[/tex], then [tex]6a=252[/tex]".
To find:
The property for the given statement.
Solution:
Multiplication property of equality: Let [tex]a,b,c[/tex] are real numbers.
If [tex]a=b[/tex], then [tex]ac=bc[/tex].
We have,
[tex]a=42[/tex]
Using the multiplication property of equality, multiplying both sides by 6.
[tex]6\cdot a=6\cdot 42[/tex]
On simplification, we get
[tex]6a=252[/tex]
Therefore, the required property for the given statement is multiplication property of equality.

B is the midpoint of AC and E is the midpoint of BD. if A(-9,-4), C(-1, 6), and E(-4, -3) find coordinates of D
Answers
Answer: The coordinates of D are (-3, -7).
Step-by-step explanation:
First, we need to find the coordinates of B. In order to do that, take the average of the two points that make up the segment which are A and C.
Average of x's: -9 + -1 = -10/2 = -5
Average of y's: -4 + 6 = 2/2 = 1
Therefore, the coordinates of B are (-5, 1). Coordinates are always (x,y).
Now we can find D by noting that the E will be the average of B and D. So we can use the average equation to determine the value of D.
Average of the x's:
(B + D)/2 = E
(-5 + D)/2 = -4
-5 + D = -8
D = -3
Average of the y's:
(B + D)/2 = E
(1 + D)/2 = -3
1 + D = -6
D = -7
The coordinates of D are (-3, -7).

Rational numbers have repeating patterns, like 0.9898989898989898… where it’s just 98 over and over.
Irrational number do not have a repeating pattern.
In your number, there’s one more 8 each time, so 98, then 988, then 9888, then 98888, and so on. So it’s not repeating. Because it’s not repeating, you know it’s irrational.
