2x³ - 32x ← factor out 2x from each term
= 2x(x² - 16) ← difference of squares
= 2x(x - 4)(x + 4)
(29)
3x² + 6x + 3 ← factor out 3 from each term
= 3(x² + 2x + 1) ← perfect square
= 3(x + 1)²

[tex]x^{4}[/tex] - 81 ← difference of squares
= (x² - 9)(x² + 9) ← (x² - 9) is also a difference of squares

5[tex]x^{5}[/tex] - 15[tex]x^{4}[/tex] + 10x³ ← factor out 5x³ from each term

Find the value of b if the graph of the equation y=−5x+b goes through the G(4, 3) point.
Answers
Answer:
b = 23
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
y = -5x + b
G(4, 3)
Step 2: Find y-intercept b
Substitute point: 3 = -5(4) + bMultiply: 3 = -20 + bAdd 20 to both sides: 23 = bStep 3: Write linear equation
y = -5x + 23
Answer:
The answer is y=-5x+21.5 --- B=21.5

Given the definitions of f(x) and g(x) below, find the value of g(f(-3)).
Answers
Answer:
-11
Step-by-step explanation:
f(x) = 5x + 11
g(x) = x^2 + 4x - 11
g(f(-3)) = ?
f(-3) = 5(-3) + 11
= -15 + 11 = -4
g(f(-3)) = g(-4) = -(4)^2 + 4(-4) - 11
= 16 - 16 - 11 = -11
A function assigns the value of each element of one set to the other specific element of another set. The value of g(f(-3)) is -11.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given f(x)=5x+11 and g(x)=x²+4x-11, therefore, we can write the value of g(f(x)) as,
g(f(x)) = (5x + 11)² + 4(5x + 11) - 11
= 25x² + 121 + 110x + 20x + 44 - 11
= 25x² + 130x + 154
Now, substitute the value of x as -3 in the function g(f(x)), therefore, we can write,
g(f(-3)) = 25x² + 130x + 154
= 25(3)² + 130(-3) + 154
= 225 - 390 + 154
= -11
Hence, the value of g(f(-3)) is -11.

A map shows a section of Interstate 94 that forms a straight line. A family plans to drive 72 miles on Interstate 94 from St Paul, MN to Elk Mound, WI. They drive for 20 miles, and then decide they will stop halfway through their trip to eat. How much farther do they need to drive before they stop for dinner?
Answers
Answer:
16 miles
Step-by-step explanation:
Given that:
Total distance of the trip = 72 miles
They have decided to stop half way their trip i.e. they will stop at a distance [tex]\frac{72}{2} =36[/tex] miles from the starting point.
Also, given that they have already traveled for 20 miles.
To find:
How much farther do they need to drive before they stop for dinner?
Solution:
Distance already covered = 20 miles
Distance to be covered before stopping for dinner = 36 miles
Distance to be covered more = Total distance to be covered before stopping - Distance already covered
[tex]\Rightarrow 36-20 =\bold{16\ miles}[/tex]

Answer:
x = -11.2
Step-by-step explanation:
0.1 + 0.2x + 0.3 + 0.05x = -2.4
Combine like terms on the left side.

Subtract 0.4 from both sides.
0.25x = -2.8
Divide both sides by 0.25.
x = -11.2
