Answer:
Step-by-step explanation:
(f-g)(x) = f(x)- g(x)
= (3x + 7) - (3x)
= 7
Therefore (f-g)(x) = 7
Answer:
(f - g)(x) = 7
Step-by-step explanation:
Here, we should subtract the two functions:
f(x) = 3x + 7 and g(x) = 3x
(f - g)(x) = 3x + 7 - 3x
= 3x - 3x + 7
= 7
Hence, (f - g)(x) = 7
What is the area of the square?
24 mm
288 square millimeters
96 square millimeters
312 pi square millimeters
576 square millimeters
Answer:
576 mm²
Step-by-step explanation:
In a square all sides are equal, so area of square = s * s = s²
Area = 24 * 24
Area = 576 mm²

Answer:
c³ + 24c² + 192c + 512
Step-by-step explanation:
(c + 8)³
= (c + 8)(c + 8)(c + 8) ← expand last 2 factors using FOIL
= (c + 8)(c² + 16c + 64)
Multiply each term in the second factor by each term in the first factor
c(c² + 16c + 64) + 8(c² + 16c + 64) ← distribute parenthesis
= c³ + 16c² + 64c + 8c² + 128c + 512 ← collect like terms
= c³ + 24c² + 192c + 512
Answer:
[tex]c^{3} + 24 {c}^{2} + 192c + 512 [/tex]
Step-by-step explanation:
Expand the expression
[tex](c + 8)(c + 8)(c + 8) \\ = {c}^{3} + 3 {c}^{2} \times 8 + 3c \times {8}^{2} + {8}^{3} \\ = {c}^{3} + 24 {c}^{2} 3c \times 64 + 512 \\ = {c}^{3} + 24 {c}^{2} + 192c + 512[/tex]

The length of a rectangle
is 4 meters less than twice the width.
If the area of the rectangle is 240 square meters,
The width is
meters.
The length IS
meters.
Answer:
length is 20 meters
width is 12 meters
Step-by-step explanation:
x = length
y = width
x = 2y - 4
x×y = 240
using the first equation as substitute in the second equation we get
(2y - 4)×y = 240
2y² - 4y - 240 = 0
the solution to such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
here we are going for y instead of x, but it is the same principle.
a = 2
b = -4
c = -240
y = (4 ± sqrt(16 - 4×2×-240))/4 = (4 ± sqrt(16 + 1920))/4 =
= (4 ± sqrt(1936))/4 = (4 ± 44)/4 = (1 ± 11)
y1 = 1 + 11 = 12
y2 = 1 - 11 = -10
negative side lengths don't make any sense, so, y = 12 meters remains.
x = 2y - 4 = 2×12 - 4 = 24 - 4 = 20 meters

Answer:
see explanation
Step-by-step explanation:
Substitute the given values of x into f : x → [tex]\frac{3}{7}[/tex] x + 4
x = - 14 → ([tex]\frac{3}{7}[/tex] × - 14) + 4 = (3 × - 2) + 4 = - 6 + 4 = - 2
x = 28 → ( [tex]\frac{3}{7}[/tex] × 28) + 4 = (3 × 4) + 4 = 12 + 4 = 16
x = [tex]\frac{7}{8}[/tex] → ([tex]\frac{3}{7}[/tex] × [tex]\frac{7}{8}[/tex] ) + 4 = [tex]\frac{3}{8}[/tex] + 4 = [tex]\frac{3}{8}[/tex] + [tex]\frac{32}{8}[/tex] = [tex]\frac{35}{8}[/tex]
x = - [tex]\frac{2}{9}[/tex] → ([tex]\frac{3}{7}[/tex] × - [tex]\frac{2}{9}[/tex] ) + 4 = ([tex]\frac{1}{7}[/tex] × - [tex]\frac{2}{3}[/tex]) + 4 = - [tex]\frac{2}{21}[/tex] + [tex]\frac{84}{21}[/tex] = [tex]\frac{82}{21}[/tex]
Answer:
See below in bold.
Step-by-step explanation:
1. 3/7 * -14 + 4
= -6 + 4
= -2.
2. 3/7 * 28 + 4
= 12 + 4
= 16.
3 3/7 * 7/8 + 4
= 3/8 + 4
= 35/8 or 4 3/8.
4. 3/7 * -2/9 + 4
= -6/63 + 4
= -2/21 + 4
= -82/21 or -3 19/21.

Step-by-step explanation:
x = 30°
180-30= 150
4x=150
x = 37.5
Answer:
Y = 40
Step-by-step explanation:
I do not understand that language but if it is asking what Y is equal to when x is equal to 30 degrees and EFG is a straight line.
1. 3Y + 2X = 180 (Straight angle)
2. X = 30 (given)
3. therefore 2X = 2x30
= 60
4. Therefore 3Y + 60 = 180
5. 3Y = 180 - 60
6. 3Y = 120
7. Y = 120/3
8. Y = 40

Please help! What is |x-3|=9
Answer:
x = 12 or x = -6
Step-by-step explanation:
Solve for x over the integers:
abs(x - 3) = 9
Split the equation into two possible cases:
x - 3 = 9 or x - 3 = -9
Add 3 to both sides:
x = 12 or x - 3 = -9
Add 3 to both sides:
Answer: x = 12 or x = -6

What is the average rate of change over the
interval [0.75, 1.125]? Explain the meaning
of the average rate of change.
Answer:
The average rte of change = 6
2) The average rate of change over an interval is the ratio of the total change in the determinate variable or function (values of the output of the function) to the change in the indeterminate variable (values of the input of the function)
Step-by-step explanation:
1) The average of change of the function is found as follows;
At x = 0.75, y = -0.5, at x = 1.125, y = 1.75
Therefore, the average rate of change = (1.75 - (-0.5))/(1.125 - 0.75) = 6
2) The average rate of change over an interval on a graph or of a curve is found by dividing the difference between the y-coordinate values of the two points on the graph by the difference of the x-coordinate values of the two points.
