Find the value of T when T = 2U + 4V when U = 4 and V = -5
Please help
Answers
________________________________
Hey!!!
Solution,
U=4
V=-5
Now,
T=2U+4V
=2*4+4*(-5)
=8+(-20)
=8-20
=-12
So the value of T is -12.

A teacher selects two different numbers, x and y, and states that x + y = 0. Which statement could be true about these two numbers?
Both numbers are positive.
Both numbers are negative.
One number is zero and the other is positive.
One number is positive and the other is negative
Answers
Answer:
One number is positive, and the other is negative. The numbers are additive inverses. x + y = 0 -----> y = -x

Explain. No, because for each input there is not exactly one output No, because for each output there is not exactly one input Yes, because for each input there is exactly one output Yes, because for each output there is exactly one input
Answers
No the given relation is not a function because for one input we are getting two different values of output which negates the definition of the function.
A relation is said to be a function when each and every element of domain has a unique and distinct image means we will get only one output per input.So
statement 1: No, because for each input there is not exactly one output . This is true.statement 2: No, because for each output there is not exactly one input. This is false.statement 3:Yes, because for each input there is exactly one output .This is false.statement 4:Yes, because for each output there is exactly one input.This is also false.Hence the given relation is not a function.

The given relation is not a function because for each input (x-value), there is not exactly one output (y-value).
In a function, each input (x-value) should have only one corresponding output (y-value). However, in this relation, the input value of 1 has two different output values: -2 and 3. Therefore, it violates the definition of a function.
To illustrate this, let's look at the points (-2, 0), (1, -2), and (1, 3). The x-value of 1 appears twice in the relation, but it has two different y-values associated with it. This means that for the input value of 1, there is not exactly one output value, which is why the given relation is not a function.
In conclusion, the relation is not a function because for each input there is not exactly one output.

D.12.66
pls help me
Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

The diameter of a hat is 6.8 inches. What is the distance around the hat using π = 3.14? Round to the hundredths place.
2.17 inches
10.68 inches
21.35 inches
36.29 inches
Answers
d = 6.8 in
π (in this problem) = 3.14
Keep the formula in mind: C = 2πr
We have d, but no r. However, we know that r = 1/2d, or the radius is half the diameter.
Then again, it’s 2πr, or 2rπ, ORRRRR dπ.
So 6.8(3.14) = 21.352.
The choices only go in 2 decimal places so round.
Your answer is the 3rd choice: 21.35 in.
The required distance around the hat is approximately 21.35 inches. Option C is correct.
What is the circumference of the circle?To find the circumference of a circle, we use the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14), and d is the diameter of the circle.
Here,
The distance around a circle is given by the formula circumference = π × diameter.
Substituting the given values, we get:
circumference = 3.14 × 6.8
circumference = 21.352
Rounding to the nearest hundredth, we get:
circumference ≈ 21.35 inches
Therefore, the distance around the hat is approximately 21.35 inches.

B) 60%
Step-by-step explanation:
Percentage formula
\(\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100\)
To find what percent of 200 is 120, substitute the values into the percentage formula:
\(\begin{aligned}\implies \sf Percentage & = \dfrac{120}{200} \times 100\\\\&=\dfrac{120 \times 100}{200}\\\\&=\dfrac{12000}{200}\\\\&=\dfrac{120}{2}\\\\&=60\%\end{aligned}\)

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Question : Is this RSM? Because if I knew the grade , advanced/normal/honors I would be able to help u more
Solve step by step : x=12 because it said the height is 12.
Inside, x-6, so therefor it would really be, 12-6. Which we know would be 6.
Perimeter : 60
now we know the inside is 6. The outside height is 12. 6+12=18. So the width would be 18. 18+12+18+12 = 30+30 = 60.

If h(x) = x-7 and g(x) = x2, which expression is equivalent to (gº h)(5)?
Answers
Answer: \(g(5) *h(5) = (5-7)(5^2)= (25)(-2) = -50\) Im assuming that g(x) is x^2, since you were incapable of writing the exponent sign
Step-by-step explanation:
\((g*h)(x)=g(x)*h(x)\)
So this means the functions should be multipled and both evaluated at x = 5
The value of the composition of functions ( g o f ) ( 5 ) = 4
What is Composition of functions?Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the first function be represented as h ( x )
Now , the value of h ( x ) is
h ( x ) = x - 7
Let the second function be represented as g ( x )
Now , the value of g ( x ) is
g ( x ) = x²
Now , the composition of function ( g o f ) ( 5 ) is given by
The value of f ( 5 ) = 5 - 7 = -2
Now , the value of g ( -2 ) is
g ( -2 ) = ( -2 )²
g ( -2 ) = 4
Hence , the composition of function is solved and the value is given by A = ( g o f ) ( 5 ) = 4
