1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2
A.f(–9) = 14
g(1) = 30
B.f(–9) = –78
g(1) = –11
C.f(–9) = –66
g(1) = 29
D.f(–9) = 8
g(1) = –80.75
2.Find the value of f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x3 – 24x .
A. f(–9) = 25
g(–1) = 21
B.f(–9) = –5
g(–1) = 20
C.f(–9) = 29
g(–1) = 26
D.f(–9) = 3
g(–1) = –27
Answer:
1. f(–9) = -66 , g( 1 ) = 27 (Please double-check your given options, there must have been a typographical error for Option C for g( 1 ) = 29). g( 1 ) is supposed to be 27.
2. Option A: f(–9) = 25, g(–1) = 21
Step-by-step explanation:
1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2
f(x) = 8x + 6
f(–9) = 8(-9) + 6 = -66
g(x) = 9x + 20x − 2
g( 1 ) = 9( 1 ) + 20( 1 ) − 2 = 27
None of the given choices were correct (unless there's a typo error for Option C — it's supposed to be g( 1 ) = 27 instead of 29?) because the correct answers are: f(–9) = -66 and g( 1 ) = 27
2. f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x³ – 24x
f(x) = –3x – 2
f(–9) = –3(–9) – 2 = 25
g(x) = 3x³ – 24x
g(–1) = 3(–1)³ – 24(–1) = 21
Therefore, the correct answer is Option A: f(–9) = 25, g(–1) = 21

Write an equation of a line that passes through the point T ( − 2, − 5 ) and is parallel to the line y = 5 x + 7 .
Answer:
y = 5x + 5
Step-by-step explanation:
the slope to be parallel y = 5x + 7 must still be 5. To make the line pass through T, the given point, you plug (-2, -5) into the y= mx + b formula. This becomes( -5 )= 5 (-2) + B, and you solve for b. In this equation, b = 5.

(12, 3)
(–2, –5)
(–3, 1)
(1, 15)
(5, –2)
We have to find slopes one by one.
#1
(0,1)
(12,3)
Line passes through this.
#2
(-2,-5)
Line passes through this
#3
(-3,1)
Not possible (Line passes through y axis as one co-ordinate is (0,1))
#4
( 1,15)
Line passes through this
#5

Therefore, The Line does not pass through this.
A truck can be rented from Company A for $140 a day plus $0.30 per mile. Company B charges $80 a day plus $0.40 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
800 miles
Step-by-step explanation:
140 + (0.30 x 800) = 400$, 800 miles
80 + (0.40 x 800) = 400$, 800 miles
(sorry for incorrect answer the first time, mixed up the cost and number of miles)
-7(w+4) +2w - 15 simplify
Answer:
w=-8.6 is your answer
-5w-43. is the simple version
Step-by-step explanation:
First distrubute the -7 and set equal to 0 so that we can move the w to the other side.
-7w-28+2w-15=0
-5w-43=0
add 43 to both sides so you can slove for w
-5w=43
divide both sides by -5 to isolate the w
w=-8.6
whats 186,282 rounded to the nearest thousand ?
Answer: 186,000
Step-by-step explanation:
You round the 282 down so that it is an even thousand. <3
186,282 rounded to the nearest thousand is 186,000.
To round 186,282 to the nearest thousand, we look at the digit in the thousands place, which is '6'.
If the digit in the hundreds place is 5 or greater, we round up. If it is less than 5, we round down.
In this case, since the digit in the hundreds place is '8', which is greater than 5, we round up.
To round up, we increase the digit in the thousands place by 1 and replace all the digits to the right with zeros.
Therefore, rounding 186,282 to the nearest thousand gives us 187,000.

Module One Project Option 1 It is time to get the fish food ready for the marine life rescue missions. Over the last month, Penny's class has collected fish food in a variety of boxes. In order to ship the food, you are going to help Penny and her classmates. They are going to pack the small cubes of fish food into shipping boxes that are large right rectangular prisms. Shipping Box Fish Food 1 ft ft ft 0 ft 3 ft 3 / 4 Instructions:
Answer:
well we know the fish food 1/4 x1/4 x 1/4 = 1/64 because 4x4x4 equals 64 and denominator stays the same and the shipping boxes is simplify 3 3/4x = 15/4 and 3 becomes 3/1 and 3 1/4 becomes 13/4 and multiply 585/16
Step-by-step explanation:
Instructions- Solve the system of equations. Type in all points of intersection for the two functions and round to the nearest tenth if necessary.
f(x) = -0.5x+2
8(x) = -5x + 3
f(×)=-0,5x+2
8(×)= -5x+3
8×= -5x+3
8-5x+3
3x+3
x6
The nearest tenth as required, the point of intersection expressed as (0.2, 2.1).
To solve the system of equations, to find the points where the two functions intersect, which means the x-values where f(x) equals g(x). Let's proceed with the solution:
f(x) = -0.5x + 2
g(x) = -5x + 3
Set f(x) equal to g(x):
-0.5x + 2 = -5x + 3
Now, let's solve for x:
Add 0.5x to both sides to eliminate the term with x on the left side:
2 = -4.5x + 3
Subtract 3 from both sides:
-1 = -4.5x
Now, divide by -4.5 to isolate x:
x = -1 / -4.5
x ≈ 0.2222
Now that we have the x-value of the point of intersection, let's find the corresponding y-value by plugging x back into either f(x) or g(x). Let's use f(x):
f(x) = -0.5x + 2
f(0.2222) = -0.5(0.2222) + 2
f(0.2222) ≈ 2.1111
So, the point of intersection is approximately (0.2222, 2.1111).

(-8,10); m=1/2
Answer:
y=1/2x+14
Step-by-step explanation:
If you mark (-8,10) in a graph and go up 1, over 2, then you will eventually get to (0,14).
You can also use the slope formula in reverse. 1/2=b-10/0-(-8)
1/2=b-10/8, then multiply both side by 8
4=b-10, add 10 to both sides
14=b

Clean air has no smell
Despite all of our best intentions to make a home smell clean, the truth is that clean air should smell like nothing at all.
Step-by-step explanation:
Before the rain begins, one of the first odors you may notice as winds pick up and clouds roll in is a sweet, pungent zing in your nostrils. That's the sharp, fresh aroma of ozone—a form of oxygen whose name comes from the Greek word ozein (to smell).

The circle graph shows the results of a survey. Of those surveyed, 10 said no. About how many people were surveyed?
Answer:
50 people
Step-by-step explanation:
so to solve this we can use cross multiplying:
first we know that 20% = 10 people and 80% = x people (we put x because we don't know how many people)
then we set it up:
[tex]\frac{10}{20}[/tex] = [tex]\frac{x}{80}[/tex]
= 20x = 800
= x = 40
now it asks how many people were surveyed in total so we add the 10 + 40 = 50
50 people were surveyed
This question is bothering and hurting my brain a lot: A restaurant has a square floor with an area of 324 m². Sketch the resaurant floor. What are its dimensions?
Answer:
The dimensions are 18m by 18m
Step-by-step explanation:
Since the problem says the floor is square, we know that all 4 sides are equal. The area for a square is one side squared. Since we do not have the actual length per side, we write the following formula: x^2= 324.
From there, we simply take the square root to figure out that one side is 18 meters. Once we know one side, we know all 4 because a square has equal sides. Therefore, the dimensions of the floor are 18m x 18m. I hope this helps!
