4. If f(x) = 4x-8 and g(x)=x-2, evaluate (f-g)(x).
algebra 2
Answer:
(f - g)(x) = 3x - 6
General Formulas and Concepts:
Pre-Algebra
Distributive PropertyAlgebra I
Combining like termsStep-by-step explanation:
Step 1: Define
f(x) = 4x - 8
g(x) = x - 2
(f - g)(x) is f(x) - g(x)
Step 2: Find
Substitute: (f - g)(x) = 4x - 8 - (x - 2)Distribute negative: (f - g)(x) = 4x - 8 - x + 2Combine like terms: (f - g)(x) = 3x - 6Which of these medical devices typically uses the most advanced and recently developed technology?

Which transformation rule below translate points 5 units to the left and 2 units up? *
(1 Point)
(x y) --> (x + 5, y + 2)
(x, y) --> (x - 5. y - 2)
(x, y) --> (x + 5. y - 2)
(x, y)--> (x - 5. y + 2)
Please I need help
Answer:
(x, y)--> (x - 5. y + 2)Step-by-step explanation:
Given the coordinate (x, y), when transforming the coordinate, up and right, the value of the constant we are using must be added to the coordinate since positive x axis acts towards the right side and the positive y axis acts upwards.
Also, when transforming the coordinate down and left, the value of the constant we are using must be subtracted from the coordinate since negative x axis acts towards the left side and the negative y axis acts downwards.
According to the question, we are to translate the coordinate (x, y) 5 units to the left and 2 units up,
Translating 5 units to the left means the x coordinate will become x--> (x-5)
Translating 2 units up means the y coordinate will become x--> (x+2)
Hence the correct transformation rule will be (x, y)--> (x - 5. y + 2)

The points (0, -1) and (4,5) lie on the straight line L
Work out the gradient of L.
Answer:
gradient = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Calculate the gradient m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (4, 5)
m = [tex]\frac{5+1}{4-0}[/tex] = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]

Estimate a 15% tip on a dinner bill of $47.67 by first rounding the bill amount to the nearest ten dollars.
Answer:
The tip will be $7.2
And the total paid will be $55.20 or $55 rounded
Step-by-step explanation:
The equation is
48 x 0.15 = 7.2
48 + 7.2 = 55.2
55.2 rounded equals 55
The length of rectangle A is 7.4 cm and the width is 4.8 cm. The perimeter of rectangle B is 14.9 cm. How much is the perimeter of rectangle A than the perimeter of rectangle B?
Answer: 9.5 cm
Step-by-step explanation:
First we have to find the perimeter of rectangle A:
Formula for perimeter of a rectangle or square is: [tex]2(a+b)[/tex]
Putting the length and width in: [tex]2(7.4+4.8)[/tex]
Solve it to get: 24.4 cm
Subtract 14.9 from 24.4 to get 9.5 cm
A 52kg person walks from the ground to the roof of 78.52m tall building. How much gravitational potential energy is there?USE GRESA METHOD
Answer:
P = 40013.792 J
Step-by-step explanation:
Given that,
Mass of a person, m = 52 kg
The height of the building, h = 78.52 m
We need to find the gravitational potential energy at this point. It is given by the formula as follows :
P = mgh
Where g is acceleration due to gravity
P = 52 kg × 9.8 m/s² × 78.52 m
P = 40013.792 J
So, the gravitational potential energy is 40013.792 J.

= 307,000,000
= 3.07 . 10^8.
9. Which is a solution of the equation 5(x – 8) = -55 ?
a) x = 3
b) x = 13
c) x = -3
d) x = -9.4
Answer: c. x = -3
5(x - 8) = -55
⇔ 5x - 40 = -55
⇔ 5x = -55 + 40 = -15
⇔ x = -15/5
⇔ x = -3

Answer:
x = 26
Step-by-step explanation:
Alternate exterior angles are always congruent
3x - 8 = 70
Add 8 to both sides;
3x = 78
Divide both sides by 3;
x = 26

Step-by-step explanation:
Two similar triangles are in the ratio 2:3. If the sides of the bigger triangle are 15 units, 12 units and 9 units, then the length of the shortest side of the smaller triangle is
a. 8 units
b. 6 units
c. 9 units
d. 5 units
It is 6 units because if you divide 9 by 3 you get 3 and you multiple that by 2 to make it 6:9 which is equal to 2:3
