One way to show that a statement is NOT a good definition is to find a ____. a. converse b. counterexample c. biconditional d. conditional
Answer: b. counterexample
A counterexample contradicts the statement or definition you're trying to set up.
For example, if you said that 2x+3x = 7x was true for all x values, then all you need to do is try something like x = 2 to find the original equation simplifies to 10 = 14, which is false. In this case, the counterexample is x = 2 invalidating the equation 2x+3x = 7x.
Determine the standard form of the equation of the line that passes through (-2, 0) and (-8, 5).
5x + 6y = 10
5x - y = - 10
6x + 5y = - 10
d. 5x + y = -10
C.
b.
Please select the best answer from the choices provided
A

D
Answer:
5x + 6y = -10
Step-by-step explanation:
(-2, 0) and (-8, 5)
m = (y₂ - y₁) / (x₂ - x₁)
m = (5 - 0) / (-8 -(-2)
m = 5 / (-8+2)
m = -5/6
y = mx + b
(-8, 5)
5 = -5/6(-8) + b
5 = 40/6 + b
b = 5 - 40/6
b = -5/3
y = mx + b
y = -5/6x - 5/3 *6
6y = -5x -5(2)
6y = -5x - 10
5x + 6y = -10

If fx = 3x over 5 +3 which of the following is the inverse
Answer:
f^(-1)(x) = -3x/(3x-3)
Step-by-step explanation:
1) replace f(x) by y
● y = 3x/(5x+3)
2) exchange x and y
● y = 3x/(5x+3)
● x = 3y / (3y +3)
3) solve for y
● x = 3y / (3y +3)
● x (3y +3) = 3y
● 3xy + 3x = 3y
● 3xy - 3y = -3x
● y (3x - 3) = -3x
● y = -3x /(3x-3)
4) replace y with f^(-1)(x)
● y = -3x/(3x-3)
● f^(-1)(x) = -3x/(3x-3)

Rewrite the quadratic equation in the form y=a(x - h)^2 + k
y= 4x^2 -16x + 64
Answer:
y = 4(x - 2)² + 48
Step-by-step explanation:
Given
y = 4x² - 16x + 64
Using the method of competing the square
Factor out 4 from 4x² - 16x
y = 4(x² - 4x) + 64
add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = 4(x² + 2(- 2)x + 4 - 4 ) + 64
= 4(x - 2)² - 16 + 64
= 4(x - 2)² + 48
y = 4(x - 2)² + 48
Step-by-step explanation:

Which two transformations must be applied to the graph of y = ln(x) to result in the graph of y = –ln(x) + 64?
A) reflection over the x-axis, plus a vertical translation
B) reflection over the y-axis, plus a vertical translation
C) reflection over the x-axis, plus a horizontal translation
D) reflection over the y-axis, plus a horizontal translation
Answer: A) reflection over the x-axis, plus a vertical translation
Step-by-step explanation:
Ok, when we have a function y = f(x)
> A reflection over the x-axis changes a point (x, y) to a point (x, -y), then for a function (x , y = f(x)) the point will change to (x, -y =- f(x))
then for a funtion g(x), this tranformation can be written as h(x) = -g(x).
> A vertical translation of A units (A positive) up for a function g(x) can be written as: h(x) = g(x) + A.
Then in this case we have:
y = g(x) = ln(x)
and the transformed function is h(x) = -ln(x) + 64
Then we can start with h(x) = g(x)
first do a reflection over the x-axis, and now we have:
h(x) = -g(x) = -ln(x)
And now we can do a vertical translation of 64 units up
h(x) = -g(x) + 64 = -ln(x) + 64
Then the correct option is:
A) reflection over the x-axis, plus a vertical translation

Help please!!!!!!!!:(
Answer:
Step-by-step explanation:
As seen from the first given equation: x + 1/x = 2
If we think of x as x/1 instead then we get:
x/1 + 1/x = 2.
To combine the fractions we multiply the top and bottom of the first one (x/1) by x to get x^2/x so both have the same denominator so we can combine them which gives us:
(x^2+1)/x=2
Move x to the other side and we get:
x^2+1=2x
Move it back and we get a quadratic equation of
x^2 - 2x + 1
This factors into (x-1)(x-1) meaning x=1
For all the other equations they are equal because x=1.
1 to the power of anything is still one so each of the equations below will result in: 1+1/1 which is 2.
Therefore all of them are equal.

What is the value of y in the equation 6.4x + 2.8y = 44.4, when x = 3?
Answer:
y = 9
Step-by-step explanation:
Given
6.4x + 2.8y = 44.4 ← substitute x = 3 into the expression
6.4(3) + 2.8y = 44.4
19.2 + 2.8y = 44.4 ( subtract 19.2 from both sides )
2.8y = 25.2 ( divide both sides by 2.8 )
y = 9
A box contains four tiles 1,4,5 and 8 as shown. Kelly chooses one time places it back in the box then chooses a second tile. What is the probability that the sum of the two chosen tiles is greater than 7?
Answer:
the answer to that question is 11/16
Using the probability principle, the probability of picking two tiles which sums above 7 is 11/16.
Recall :
Probability = required outcome / Total possible outcomesThe only way to choose two tiles which sums up to a number greater than 7 would be :
(1,8), (8, 1), (4, 5), (5,4), (4, 8), (8,4), (5,8), (8,5), {4, 4}, {5, 5}, {8, 8}Since selection is performed with replacement ;
Total possible outcome = sample size = 4² = 16The probability of choosing two tiles whose sum is greater than 7 ;
11/16 =Hence, probability of choosing tiles with a sum greater than 7 is 11/16
Therefore, the probability of picking two tiles which sums above 7 is 11/16.
