1. what is the doamin and range form this graph and the minimum and maximum and interval of increase and decrease?
Answers
Answer:
Below.
Step-by-step explanation:
The Domain is all real values of x.
The range is -6 ≤ f(x) < ∞.
( I cant see the minimum value very clearly but I think its -6).
Minimum -6 Maxm ∞.
Decreasing from f(x) = -∞ to f(x) = -6.
Increasing from f(x) = -6 to ∞.

Jason made the following calculations. Explain the errors Jason made. Give the correct answers.
a. 1/3 + 3/5 = 4/8
b. 11/12 - 5/6 = 6/6 = 1
Answers
Answer:
a. 14/15
b. 1/12
Step-by-step explanation:
a) 1/3 + 3/5
so find the lowest common multiple for the denominators which is 15
then say 15 ÷ 3 = 5
then 15 ÷ 4 = 3 (you are dividing by the denominators)
say 5 × 1 (multiple by the numerators now)
= 5
= 5/15
now say 3 × 3 = 9
= 9/ 15
now it's 5/15 + 9/15
= 14/15
Jason made an error that he just added the denominators without applying any formula.
b. 11/12 - 5/6
find the lcm
= 12
11/ 12 × 1/1 = 11/12
5/6 × 2/2 = 10/12
11-10
= 1
= 1/12
Jason made a mistake that he said 12-6 instead of finding the LCD them multiplying that fractions
The errors Jason made that he did not take LCM of denominators.
What are denominators?In math, a denominator can be defined as the bottom number in a fraction that shows the number of equal parts an item is divided into.
Given are some calculations done by Jason,
We know that, to add two fractions, we take LCM of denominators and then divide the numerator by LCM and the add,
a) 1/3 + 3/5 = 4/8
Here, Jason have not taken LCM of denominators
Correction =
[tex]\frac{15(\frac{1}{3} )+15(\frac{3}{5}) }{15} \\= \frac{5+9}{15} \\=\frac{14}{15}[/tex]
b) 11/12 - 5/6 = 6/6 = 1
Again, the error is the same.
LCM(6, 12) = 12
Correction =
[tex]\frac{12(\frac{11}{12})+12(\frac{5}{6)} }{12} \\= \frac{11-10}{12} \\= \frac{1}{12}[/tex]

How do you find slopes of two points for example (9, 6) and (4, 4)?
Answers
Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
Use the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) = (4 , 4)\\(x_2 , y_2) = (9 , 6)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{6 - 4}{9 - 4} = \frac{2}{5}[/tex]
[tex]\frac{2}{5}[/tex] is your slope.
Answer:
[tex]m = \frac{2}{5} [/tex]
Step-by-step explanation:
Slope is equal to the change in y over the change in x, or rise over run.
[tex]m = \frac{change \: in \: y}{cahnge \: in \: x} [/tex]
The change in x is equal to the difference in x-coordinates and the change in y is equal to the difference in y-coordinates.
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
Substitute in the values of x and y into the equation to find the slope.
[tex]m = \frac{4 - (6)}{4 - (9)} [/tex]
Simplify.
[tex]m = \frac{2}{5} [/tex]
Therefor, the answer is m = 2/5.

There must be two mutually exclusive outcomes for each trial with a constant probability of success. B. The sum of the probabilities must equal one. Each probability must be between zero and one inclusive. C. Each probability must be between zero and one inclusive. D. The sum of the probabilities must equal one.
Answers
Answer:
B. The sum of the probabilities must equal one. Each probability must be between zero and one inclusive
Step-by-step explanation:
The discrete probability distribution is a distribution in which the random variable would be considered as countable i.e. non-negative digits also it would be presented in table form
So according to the given situation, the option b is correct as their sum would be equivalent to zero also each probability should be lies between zero and one inclusive

Which of the following are solutions to the equation below? Check all that apply. 4x2 - 12x + 9 = 5
Answers
Step-by-step explanation:
4x² - 12x + 9 = 5 → 4x² - 12x + 4 = 0 → x² - 3x + 1 = 0
∆ = b² - 4ac → ∆ = (-3)² -4(1)(1) = 9 - 4 = 5
x = (-(-3) ± √5)/2(1) = (3 ± √5)/2
x² - 3x + 1 = 0 → (x - 3/2)² - 9/4 + 1 = 0 → (x - 3/2)² = 5/4 → x - 3/2 = ±√5 / 2 → x = ½( 3 ± √5)

if the sum of two expressions is 3x+5 and one expression is 5x-7 what is the other expression
Answers
Answer:
-2x + 12
Step-by-step explanation:
If we call our other expression y, we can set up an equation tying together 3x + 5, y, and 5x - 7:
[tex](5x-7)+y=3x+5[/tex]
Solving for y by subtracting 5x - 7 from both sides will get us the expression we're looking for:
[tex]y=3x+5-(5x-7)\\y=3x+5-5x+7\\y=-2x+12[/tex]
So the other expression in the sum is -2x + 12.
