1) What is the product of (3x + 2) and (x - 7)?
2) What are the factors (multiplier) of 3x2 − 9x ?
Answer both of the questions
Answer:
1) [tex]3x^{2}[/tex]-19x-14
2) x=0, x=3
Step-by-step explanation:
1) (3x+2)(x-7)
Distribute the 3x to both x and -7, as well as the 2 to both x and - 7.
[tex]3x^{2}[/tex] - 21x + 2x -14
Combine like terms
[tex]3x^{2}[/tex] - 19x - 14
2)
In order to find the factors of x, set the expression equal to 0.
[tex]3x^{2}[/tex] - 9x = 0
Factor out the highest common multiple (3x)
3x(x-3) = 0
In order for x to satisfy the equality, you must either have a 0 in the parenthesis -> (x-3)=0 -> x =3
Or 3x = 0 -> x = 0
Hope this helps!
Renae has been playing Tower of Hanoi and has noticed that the minimum number of moves it takes to defeat the game is related to the number of disks she must move. She has recorded her observations below. Write an equation that describes this pattern. Show your work.
Number of Disks in the Tower ║Minimum Number of Moves
1 ║1
2║ 3
3 ║7
4 ║15
5 ║31
Answer:
[tex]y = 2^x - 1[/tex]
Step-by-step explanation:
Let the number of disks be x and the minimum number of moves be y.
[tex]y = 2^x - 1[/tex]
When x = 1: y = 1
[tex]y = 1 = 2 - 1 = 2^1 - 1[/tex]
When x = 2: y = 3
[tex]y = 3 = 4 - 1 = 2^2 - 1[/tex]
When x = 3: y = 7
[tex]y = 7 = 8 - 1 = 2^3 - 1[/tex]
When x=4: y = 15
[tex]y = 15 = 16 - 1 = 2^4 - 1[/tex]
When x = 5: y = 31
[tex]y = 31 = 32 - 1 = 2^5 - 1[/tex]
Notice that for each derived expression of y, the exponent of 2 is being replaced by the value of x.
The general equation is: [tex]y = 2^x - 1[/tex]

Solve the equation 17=5k-3
Answer:
4
Step-by-step explanation:
Simplifying
17 = 5k + -3
Reorder the terms:
17 = -3 + 5k
Solving
17 = -3 + 5k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '-5k' to each side of the equation.
17 + -5k = -3 + 5k + -5k
Combine like terms: 5k + -5k = 0
17 + -5k = -3 + 0
17 + -5k = -3
Add '-17' to each side of the equation.
17 + -17 + -5k = -3 + -17
Combine like terms: 17 + -17 = 0
0 + -5k = -3 + -17
-5k = -3 + -17
Combine like terms: -3 + -17 = -20
-5k = -20
Divide each side by '-5'.
k = 4
Simplifying
k = 4

which figure is the image of figure 1 after reflection over the y-axis and a translation 3 units down?
The image of figure 1 after reflection over the y-axis and a translation 3 units down is figure B.
What is the reflection on y-axis?When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).
Coordinates of figure 1 are (-1, 1), (-1, 2), (-2, 2), (-3, 1), (-2, 4) and (-3, 4)
Reflection on y-axis, we get
(1, 1), (1, 2), (2, 2), (3, 1), (2, 4) and (3, 4)
Translation 3 units down
(1, 1-3), (1, 2-3), (2, 2-3), (3, 1-3), (2, 4-3) and (3, 4-3)
(1, -2), (1, -1), (2, -1), (3, -2), (2, 1) and (3, 1)
Figure B has following coordinate points, (1, -2), (1, -1), (2, -1), (3, -2), (2, 1) and (3, 1)
Therefore, the image of figure 1 after reflection over the y-axis and a translation 3 units down is figure B.

If PQRS is a kite, find m angle Q
Answer:
Q = 35
Step-by-step explanation:
1. You add both (m)x values and y values making them equal to 180 creating a 2 step-equation: (7x+2) + (10x-31) making that 17x-33= 180
2. Now you have a 2 step-equation to solve: 17x-33 = 180-33=147
+-33 +-33
__________
17x = 147/17=21
/17 /17
3. From here with 21, knowing the kite must equal to 180, you add 21 to the other angle 124: 124+21=145
4. Seeing that you don't have a total of 180, you now subtract 145 from 180 in order to get the value of Q: 180-145= 35
Q= 35
Step-by-step explanation:
7x + 2 = 10x - 31
33 = 3x
x = 11
so, 7x + 2 = 7( 11 ) +2 = 79°
10x - 31 = 10( 11 ) - 31 = 79°
ΔP + ΔQ + ΔR + ΔS = 360°
79° + ΔQ + 79° + 124° = 360°
ΔQ + 282° = 360°
ΔQ = 360° - 282°
ΔQ = 78°

Find an explicit formula for the geometric sequence -40,-20,-10......
Note: the first term should be c(1).
c(n)= ?
Answer:
The explicit formula for the geometric sequence is [tex]c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}[/tex].
Step-by-step explanation:
By definition of geometric sequence, we should use the following expression:
[tex]c(n) = c_{1}\cdot r^{n-1}[/tex], [tex]n \ge 1[/tex] (1)
Where:
[tex]c_{1}[/tex] - First term.
[tex]r[/tex] - Geometric rate.
[tex]n[/tex] - Position of the element within the series.
If we know that [tex]c_{1} = -40[/tex] and [tex]r = \frac{1}{2}[/tex], then the explicit formula for the geometric sequence is:
[tex]c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}[/tex]
The explicit formula for the geometric sequence is [tex]c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}[/tex].

Greg went to the store. He bought 5 kilograms of purple beads, 1/2 of a kilogram of orange beads, and 2 kilograms of white beads. How much did he spend?
Answer:
Altogether, Greg spent $22.71.
Step-by-step explanation:
1) 5kg × $2.75 = $13.75
Purple beads: Spent $13.75
2) 1/2 kg = 1.5kg
1.5kg × $1.84 = $2.76
Orange beads: Spent $2.76
3) 2kg × $3.10 = $6.20
White beads: Spent $6.20
4) Add them all together.
$13.75 + $2.76 + $6.20 = $22.71

A rental car company charges $55.98 per day to rent a car and $0.14 for every
mile driven. Joseph wants to rent a car, knowing that:
• He plans to drive 375 miles.
• He has at most $300 to spend.
What is the maximum number of days that Joseph can rent the car while
staying within his budget?
Answer:
4 days
Step-by-step explanation:
0.14 × 375= $52.50
$300-52.50=247.50
247.50 ÷55.98= 4.42122186495
round 4.42122186495 to the nearest whole that won't go over 300 and its 4 at $223.92 and the if you add your 52.50 thats $276.42

Write the equation of the line that passes through the points (4, -8) and (-8, 1).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y = -3/4x -5
Step-by-step explanation:
(4, -8) and (-8, 1)
m = (y2-y1)/(x2-x1)
m= (1+8)/(-8-4)
m = (9)/(-12)
m = -3/4
y - y1 = m(x-x1)
y + 8 = -3/4(x -4)
y + 8 = -3/4x + 3
y = -3/4x -5
Answer:
y = -3/4x - 5

at 3 weeks old, a corn is 4 inches tall and at 15 weeks it is 44 inches tall. calculate the rate of change.
Answer:
Im not a hundred percent sure if this is the right answer but im pretty sure it is 3.33333 repeated so the rate of change is 3 inches per week.
Step-by-step explanation:
I calculated the problem by subtracting the weeks from each other subtracting the amount of length corn has grown too. I found that the corn grew 40 inches in 12 weeks. So I divided the amount of weeks and the amount it has grown and it gave me 3.333333 repeated which makes the answer 3 inches per week. correct me if im wrong...
Hope this helps:)
