Answer:
t ≥ 0.5625
Step-by-step explanation:
Given:
21 + 112t ≥ 84
112t ≥ 84 - 21
112t ≥ 63
t ≥ 63/112
t ≥ 0.5625

Which of the following statements best compares the maximum value of the two functions?
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.

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

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!!
