A. y = 1/3 (-3) - 3 = - 6
B. y = 2(-3)^2 - 3(-3) - 2
= 2(9) - 3(-3) - 2
= 18 + 9 - 2
= 25
C. 2(-3) - 5y =4
- 6 - 4 = 5y
y = - 2
Answer:
A = -6
B = 25
C = 2
Step-by-step explanation:
-3*1/3 = -1, and -1-5=-6
2(-3)^2=2(9)=18 -3*-3=9 18+9=27 27-2=25
for the last rewrite the equation
2x-4=5y

The graph shows the function representing the recommended amount of mulch, in cubic yards, for circular flowerbeds based on the radius of the flowerbed in feet. If the vertex of the function is at the point (0, 0.5), what is the recommended amount of mulch for a flowerbed with a radius of 20 feet? Round to the nearest tenth if necessary. 7 cubic yards 13 cubic yards 25.5 cubic yards 31 cubic yards
Answer:
B, 13 cubic yards.
Step-by-step explanation:
You didn't give a graph, but I'm assuming you had the same question as me (I attached the graph that I had). I took the test and got the right answer.
The recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards
How to determine the recommended amount of mulch?The vertex of the graph is given as:
Vertex = (0,0.5)
The equation of the graph is given as:
[tex]y = 0.5 * 1.177^x[/tex]
When the radius is 20 feet, we have:
y = 0.5 * 1.177²⁰
Evaluate
y = 13.02
Approximate
y = 13.0
Hence, the recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards

What is the length of the x-component of the vector shown below?
Answer:
13.91
Step-by-step explanation:
The question lacks the required diagram. Find the diagram attached.
From the diagram the length of the vector along x component is given as:
Vx = Vcos(theta)
theta is the angle between the vector and the x axis
V is the length of the vector
Given
theta = 22°
V = 15
Substitute the given values into the formula above
Vx = 15cos22°
Vx = 15×0.9272
Vx = 13.91
Hence the length of the x-component of the vector is approximately 13.91

A new car is available with standard or automatic transmission, two or four doors, and it is available in 10 exterior colors. What is the number of possible outcomes? a.14 b.40 c.44 d.104
Answer:
40
Step-by-step explanation:
Given that:
Number of options available for transmission = 2 (Standard or Automatic)
Number of options for doors = 2 (2 doors or 4 doors)
Number of exterior colors available = 10
To find:
Total number of outcomes = ?
Solution:
First of all, let us calculate the number of outcomes for the transmission mode and number of doors options.
1. Standard - 2 doors
2. Standard - 4 doors
3. Automatic - 2 doors
4. Automatic - 4 doors
Number of outcomes possible = 4 (which is equal to number of transmission mode available multiplied by number of doors options i.e. 2[tex]\times 2[/tex])
Now, these 4 will be mapped with 10 different exterior colors.
Therefore total number of outcomes possible :
Number of transmission modes [tex]\times[/tex] Number of doors options [tex]\times[/tex] Number of exterior colors
2 [tex]\times[/tex] 2 [tex]\times[/tex] 10 = 40
The number of possible outcomes of a new car will be 40. Then the correct option is B.

Jim was offered a job as a computer programmer making 65K per year. Another company offered Jim a position earning $1,800 a week. What job pays more?
Answer:
since second company salary, $93,600, is more than first company yearly salary of $65000
Second company pays more
Step-by-step explanation:
To check what job pays more we have to compare yearly salary of both the company offer.
_________________________________________________
Yearly salary from one company = 65k = 65000
Weekly salary from another company = $1800
there are 52 weeks in a year
to get yearly salary , we need to multiply weekly salary with 52.
Yearly salary from another company = Weekly salary*no of wees in a year
Yearly salary from another company = 52*$1800 = $93,600
since second company salary, $93,600, is more than first company yearly salary of $65000
Second company pays more

Step 1: Take square root.
x=±√64
x=8 or x=−8
Answer:
x=8 or x=−8
factoring
x2=64
Step 1: Subtract 64 from both sides.
x2−64=64−64
x2−64=0
Step 2: Factor left side of equation.
(x+8)(x−8)=0
Step 3: Set factors equal to 0.

I still don't get how to do this: Solve for t then simplify your answer. -6/5t=9
Answer:
t= -15/2 or t= -7.5
Step-by-step explanation:
We are given the equation:
[tex]\frac{-6}{5}t=9[/tex]
and asked to solve for t. Therefore, we must isolate t on one side of the equation.
t is being multiplied by -6/5. The inverse of multiplication is division. We should divided both sides by -6/5, but we are dividing by a fraction. Instead, we can multiply by the reciprocal.
To find the reciprocal, flip the numerator (top number) and denominator (bottom number).
-6/5 ----> -5/6
Multiply both sides of the equation by -5/6
[tex]\frac{-5}{6} *\frac{-6}{5}t=9 *\frac{-5}{6}[/tex]
[tex]t=9 *\frac{-5}{6}[/tex]
[tex]t=\frac{9}1 *\frac{-5}{6}[/tex]
Multiply across the numerator and denominator.
[tex]t= \frac{9*-5}{1*6}[/tex]
[tex]t=\frac{-45}{6}[/tex]
Simplify the fraction. Both the numerator and denominator can be divided by 3.
[tex]t=\frac{-45/3}{6/3}[/tex]
[tex]t=\frac{-15}{2}[/tex]
[tex]t= -7.5[/tex]
t is equal to -15/2 or -7.5

Answer:
x = -6
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
2(x - 7) = 5x + 4
Step 2: Distribute parenthesis
2x - 14 = 5x + 4
Step 3: Subtract 2x on both sides
-14 = 3x + 4
Step 4: Subtract 4 on both sides
-18 = 3x
Step 5: Divide both sides by 3
-6 = x
Step 6: Rewrite
x = -6
Answer:
x=-6
Step-by-step explanation:
2(x-7)= 5x+4
2x - 14 = 5x+4
-2x -2x
-14 = 3x +4
- 4 -4
-18= 3x

5.5% of x =19.84
find x
Answer: 360.73
Step-by-step explanation:
When you come across any question that says [a of b] is just saying a × b.
5.5% of x=5.5% × x
-----------------------------------------------------------------
Given
5.5% of x=19.84
Converted into numerical expression
5.5% × x=19.84
Divide both sides by 5.5% (0.055)
x=19.84 ÷ 5.5%
simplify
x=360.73 (rounded)
Answer:
360.7273
Step-by-step explanation:
5.5% of 'x' is 19.84
so, x*5.5/100 = 19.84
or, x*5.5 = 1984
or, x = 1984/5.5
so, x=360.7273(answer)
