Answer:
We conclude that:
X∩Y∩Z = {2, 4, 7, 9}
Step-by-step explanation:
What is the intersection of three sets:
We know that the intersection of three given sets represents the largest set which consists of all the elements that are common to all the sets.
What is the symbol of the intersection of the sets:
The intersection of sets is denoted by the symbol '∩'.
Determining the intersection of the sets:
Given
X= {1,2,4,6,7,8,9}
Y= {1,2,3,4,7,9)
Z= {2,3,4,7,9)
Thus,
X∩Y∩Z = {2, 4, 7, 9}
Therefore, we conclude that:
X∩Y∩Z = {2, 4, 7, 9}

The maximum value is the same for both functions.
Of(x) has a greater maximum value than g(x).
O g(x) has a greater maximum value than f(x).
The maximum values cannot be determined.
Answer:
x=67
Step-by-step explanation:
The correct statement is,
(B) f(x) has a greater maximum value than g(x).
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Function f (x) is,
f (x) = - 8x² + 7
Now, First, we determine the maximum point of f(x).
f(x) is at maximum at the point of symmetry, i.e. where x = - b/a
Here, a = -8, b = 0
Hence, x = - 0 / - 8 = 0
So, We get;
f (0) = - 8 x 0 + 7 = 7
Thus,
The maximum point of f(x) is (0,7)
And, The maximum point of g(x) is (2,6)
Therefore, f(x) has a greater maximum value than g(x).
Hence3, The correct option is B.

Abigail has $30.00 to buy groceries. She needs to buy some apples, some bananas, and 3 pounds of potatoes. Fuji apples are $1.79 a pound, bananas are $0.36 each, and potatoes are $2.99 for a 3 lb. bag. If a represents the number of pounds of apples Abigail buys and b represents the number of bananas she buys, which expression represents the amount of change she receives after her purchases?
30.00 – a – b
1.79a + 0.36b + 2.99
30.00 – (1.79a + 0.36b + 2.99)
30.00 + (1.79a + 0.36b + 2.99)

Molly bought c candy canes. She paid $1.05, including tax, per candy cane. She gave the cashier $10 and received $1.60 in change. How many candy canes did Molly purchase? Please hurry
Answer:
Number of candy = 8 candy canes.
Step-by-step explanation:
Cost per candy = $1.05
Amount paid = $10
Change received = $1.60
Total cost = amount paid - change received
Substituting into the equation, we have;
Total cost = 10 - 1.6
Total cost = 8.4
To find the number of candy purchased;
Number of candy = total cost/cost per candy
Number of candy = 8.4/1.05
Number of candy = 8 candy canes.
Therefore, Molly purchased 8 candy canes.

The sides of the two triangles are same except , BD and DC.
It is known that the side opposite to the bigger angle is always bigger
therefore BD > DC
12 > 2x- 6
18 > 2x
9 > x
x < 9
and the value of a side is always greater than 0
therefore
2x-6 > 0

Javier solved the equation 32=2(k+4)32=2(k+4). He made a mistake in his reasoning. What is his mistake and what should he have done differently?
Answer: I am pretty sure the mistake would be where he put the variable k.
Step-by-step explanation:
You know the variable equals 8 because 2x8=32. You can change the equation to 2(32+2) Therefore, the variable diesnt equal 2, so 32=2(k+4) doesnt work. Hope this helps!!

Work out the value of 4 little 5 at top of four
Answer:
1024
Step-by-step explanation:
Assuming you mean [tex]4^{5}[/tex] , then
[tex]4^{5}[/tex] = 4 × 4 × 4 × 4 × 4 ( 4 multiplied by itself 5 times )
= 16 × 16 × 4
= 256 × 4
= 1024
Simplify the expression using the distributive property:
-4 (5x – 10)
To use the distributive property, we will multiply each term inside the parenthesis by the term outside of the parenthesis.
-4 * 5x + -10 * -4
-20x + 40
Hope this helps!! :)
Answer:
the result using the distributibe is: -20x +40
