What is the Domain, Range, Decreasing, Increasing, Y-Intercept, X-Intercept, Maximum, and Minimum of the graph shown?
Step-by-step explanation:
I am not able to see the whole graph, but what I could see is that
domain=22
range=11
the x-intercept is there is no x-intercept!
y-intercept is 2
max is 10
minimum is 1
I am so sorry! But if you let me know about the decreasing and increasing values like that are they asking for? The greatest places in the graph where it increases or decreases?
Hope that helps :)

The price list is shown.
How much will the fruit for the fruit salad cost? Show your work.
Answer:
82.8 for the strawberries
2.49 for the bannanna
44.8 for the grapes
35.76 for the oranges
The total is 165.85
Step-by-step explanation:
The cost of fruits for fruit salad is $200.59.
Given that, fruits for fruit salad and their costs are listed below.
How to add decimal numbers?Adding decimals is similar to the usual addition of whole numbers. We know that a decimal number is a number with a whole number part and a fractional part which is separated by a decimal point.
Total cost of blueberries
= 14 × 2.48 = $34.72
Total cost of strawberries
= 23 × 3.60 = $82.8
Total cost of bananas
= 1 × 2.49 = $2.49
Total cost of grapes
= 14 × 3.20 = $44.8
Total cost of oranges
= 12 × 2.98 = $35.78
So, total cost of fruits for fruit salad
= 34.72+82.8+2.49+44.8+35.78 = 200.59
Therefore, the cost of fruits for fruit salad is $200.59.

A 36-oz bottle of water costs $2.88.
What is the cost per ounce?
The cost of the water bottle per ounce is $0.077.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a 36-oz bottle of water costs $2.88. The cost of 1 ounce of the bottle is calculated as,
1 OZ = 1.04 ounces
36 OZ = 36 x 1.04 ounces
36 OZ = 37.44 ounces
37.44 ounces = $2.44
1 ounce = $2.44 / 37.44
1 ounces = $0.077

Given triangle abc with vertices A(2,-1), B(5,6), C(-1,4) as shown. Find the number of square units in the area of triangle abs in simplest form.
Answer:
The area of the triangle is 18 square units.
Step-by-step explanation:
First, we determine the lengths of segments AB, BC and AC by Pythagorean Theorem:
AB
[tex]AB = \sqrt{(5-2)^{2}+[6-(-1)]^{2}}[/tex]
[tex]AB \approx 7.616[/tex]
BC
[tex]BC = \sqrt{(-1-5)^{2}+(4-6)^{2}}[/tex]
[tex]BC \approx 6.325[/tex]
AC
[tex]AC = \sqrt{(-1-2)^{2}+[4-(-1)]^{2}}[/tex]
[tex]AC \approx 5.831[/tex]
Now we determine the area of the triangle by Heron's formula:
[tex]A = \sqrt{s\cdot (s-AB)\cdot (s-BC)\cdot (s-AC)}[/tex] (1)
[tex]s = \frac{AB+BC + AC}{2}[/tex] (2)
Where:
[tex]A[/tex] - Area of the triangle.
[tex]s[/tex] - Semiparameter.
If we know that [tex]AB \approx 7.616[/tex], [tex]BC \approx 6.325[/tex] and [tex]AC \approx 5.831[/tex], then the area of the triangle is:
[tex]s \approx 9.886[/tex]
[tex]A = 18[/tex]
The area of the triangle is 18 square units.

1/11
1/3
1/2
1/13
Answer:
1/3
If 4 are snickers and 8 are mars bars then 4/12 would be snickers so when you simplify 4/12 you get 1/3.

Kevin started the number pattern shown below using the rule "start with 1, multiply the previous number by 3 then add 2 to the result to get the next number." 1, 5, 17, …… What is the fifth number in her pattern?
Answer: 161
Step-by-step explanation:
From the question, the rule is that we start with 1, multiply the previous number by 3 then add 2 to the result to get the next number.
Based on the numbers already given such as 1, 5, 17, the 4th number will be:
= (17 × 3) + 2
= 51 + 2
= 53
The 5th number will be:
= (53 × 3) + 2
= 159 + 2
= 161
show work to determine if (1,4) is a solution to the system: y - 2x = 2 and y=4x - 6
Answer:
not a solution
Step-by-step explanation:
To determine if (1, 4) is a solution to the system
Substitute x = 1, y = 4 into the equations and check validity
y - 2x = 2
y - 2x = 4 - 2(1) = 4 - 2 = 2 = right side ← True
4x - 6 = 4(1) - 6 = 4 - 6 = - 2 ≠ 4 ← False
First equation is satisfied but second is not
Thus (1, 4) is not a solution of the system
