The tables for f(x) and g(x) are shown below. What is the value of (f-g)(5)
Answer:
16
Step-by-step explanation:
(f - g)(5) = f(5) - g(5)
From the table
(f(5) = 29 and g(5) = 13 , thus
f(5) - g(5) = 29 - 13 = 16
The value of function (f-g)(5) will be 16.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function.
The tables for f(x) and g(x) are shown.
Then the value of (f-g)(5) will be
(f – g)(5) = f(5) – g(5)
(f – g)(5) = 29 – 13
(f – g)(5) = 16

What is the solution to -(2x + 4) + x = 3x − 4x − 4?
Answer:
all real numbers
Step-by-step explanation:
-(2x + 4) + x = 3x − 4x − 4
Distribute the negative sign on the left side. It is the same as having a -1 to the left of the parentheses.
-1(2x + 4) + x = 3x − 4x − 4
-2x - 4 + x = 3x - 4x - 4
Combine like terms on the left side. Combine like terms on the right side.
-x - 4 = -x - 4
Add 4 to both sides.
-x = -x
Add x to both sides.
0 = 0
You end up with a true equation. Therefore, there is an infinite number of solutions. Every real number is a solution.

What is the slope of a lines through the points (4,4) and (4,7)
Answer:
3/0 = Undefined
Step-by-step explanation:
The equation to find the slope of two different points is [tex]\frac{y2-y1}{x2-x1}[/tex]. Now, all you have to do is substitute the values in the equation so that it now looks like [tex]\\\\\frac{7-4}{4-4} = \frac{3}{0}[/tex]. Since you can't divide 3 by 0 it is considered to be undefined, meaning there are no slope for the two ordered pairs.

<x=80 (alternate interior angle )
if u have more questions like this i will helps for sure
The angle 'x' is in linear pair with ∠B and it measures 80°.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know when a transversal intersects two parallel lines pair of alternate interior angles are equal and vertically opposite angles are also equal.
Therefore, Angle vertically opposite the 100° is also 100°(∠B).
We also know that the sum of linear pair of angles is 180°,
So the measure of angle x is (180 - 100) = 80°.

The result of which expression will best estimate the actual product of (Negative four-fifths) (three-fifths) (Negative StartFraction 6 over 7 EndFraction) (five-sixths)?
(Negative 1) (one-fourth) (Negative 1) (negative 1)
(Negative 1) (one-half) (Negative 1) (1)
(Negative StartFraction 4 over 2 EndFraction) (Three-halves) (Negative two-fifths) (Five-halves)
(Negative three-fourths) (Negative three-fourths) (Negative one-fifth) (One-half)
Answer: The answer is (D.)
The estimated product of the given expression is 9/175, hence expression will best estimate the actual product is (Negative four-fifths) (three-fifths) (Negative StartFraction 6 over 7 EndFraction) (five-sixths)(Negative 1) (one-fourth) (Negative 1) (negative 1)(Negative 1) (one-half) (Negative 1) (1)(Negative StartFraction 4 over 2 EndFraction) (Three-halves) (Negative two-fifths) (Five-halves)(Negative three-fourths) (Negative three-fourths) (Negative one-fifth) (One-half). Option A and B
How to calculate thisTo appraise the product of the given expression, we will perform the calculations and rearrange the expression step by step. Here's the step-by-step calculation:
(-4/5) * (3/5) * (-6/7) * (5/6) * (-1) * (1/4) * (-1) * (-1) * (-1) * (1/2) * (-1) * (1) * (-4/2) * (3/2) * (-2/5) * (5/2) * (-3/4) * (-3/4) * (-1/5) * (1/2)
Begin by simplifying the divisions:
(-4/5) * (3/5) * (-6/7) * (5/6) * (-1) * (1/4) * (-1) * (-1) * (-1) * (1/2) * (-1) * (1) * (-4/2) * (3/2) * (-2/5) * (5/2) * (-3/4) * (-3/4) * (-1/5) * (1/2)
= (-4/5) * (3/5) * (-6/7) * (1) * (-1/4) * (-1) * (-1/2) * (-1) * (-1/5) * (1/2)
Combine the divisions:
= (4/5) * (3/5) * (6/7) * (1/4) * (1/2) * (1/2) * (1/5) * (1/2)
Multiply the numerators together and the denominators together:
= (4 * 3 * 6 * 1 * 1 * 1 * 1 * 1) / (5 * 5 * 7 * 4 * 2 * 2 * 5 * 2)
= 72 / 1400
Simplify the division:
= 9 / 175
Therefore, both options A and B give the estimated result of 9/175.

Is 0.3754152 a rational number or irrational number?
solve : 2x - 5 < 5x - 22
Answer:
x > 17/3
Step-by-step explanation:
1. Substract 2x to both sides: −5<5x−22−2x
2. Add 22 to both sides: −5+22<3x
3. Divide both sides by 3: 17/3 < x
4. Exchange the sides: x > 17/3
Thus the value of x will be in the range (17/3 , ∞) or x > 17/3 .
Given,
2x - 5 < 5x - 22
Now,
Subtract 2x to both sides:
−5<5x−22−2x
Add 22 to both sides:
−5+22<3x
Divide both sides by 3:
17/3 < x
Exchange the sides:
x > 17/3
Thus the value of x will be in the range (17/3 , ∞) .
