Answer:
-4x+3x power of 2 +2
Step-by-step explanation:
Answer:
3x² - 4x + 2
Step-by-step explanation:
distribute -2 into (3x - 1) and distribute x into (3x + 2)
=> -6x + 2 + 3x² + 2x
combine like terms
=> 3x² - 4x + 2

On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 9 kg weighs 63 N . Calculate the mass of another object that weighs 14 N.
Answer:
The mass is 2 kg.
Step-by-step explanation:
W = kM where k is a constant so
63 = k*9
k = 7
So: W = 7M
when W = 14:
14 = 7M
M = 2.

Let f(t) represent the temperature of a turkey baking in an oven as a function of time t in the oven (in minutes). This means time is the independent variable and temperature of the turkey is the dependent variable. The turkey was in the oven for 360 minutes and then removed. Note that when something is baked in an oven, the temperature of the oven stays constant.
Explain the meaning of each statement in the context of the situation using everyday language. Remember that the input of the function t is the time in the oven and the output f(t) is the temperature of the turkey at that time.
1. f(0) = 50. (8 points)
2. f(120) > f(60). (8 points)
3. f(360) = f(345). (7 points)
4. f(390) < f(360). (7 points)
Answer:
Step-by-step explanation:
1. f(0) = 50. (8 points) The beginning temperature of the turkey was 50 degrees. The '0' represents "beginning."
2. f(120) > f(60). (8 points) The temperature of the turkey after 120 min (2 hours) is greater than that after 60 minutes (1 hour).
3. f(360) = f(345). (7 points) The temperature of the turkey is the same after 360 minutes as it is after 345 minutes.
4. f(390) < f(360). (7 points)
The temperature of the turkey drops after 360 minutes (6 hours), because the turkey is taken out of the oven and/or the oven is turned off.

Ten members of Balin’s soccer team ran warm ups for practice. Each member ran the same distance. Their combined distance was StartFraction 5 Over 6 EndFraction of a mile. To find the distance that each member ran, Balin wrote the expression below.
Answer:
Each member ran (1/12) of a mile.
Step-by-step explanation:
We have 10 members of Balin's soccer team.
Each one of them ran a distance D.
We know that their combined distance was 5/6 of a mile.
And if each one of them ran the same distance D, then the combined distance is ten times D, or :
10*D
and this is equal to 5/6 of a mile, then we get the equation:
10*D = (5/6) of a mile.
We want to solve this for D, so we can divide both sides by 10:
10*D/10 = (5/6)/10 of a mile.
D = (5/10*6) of a mile
D = (5/10)/6 of a mile
D = (1/2)/6 of a mile
D = (1/2*6) of a mile
D = (1/12) of a mile.
This means that each member ran (1/12) of a mile.

Step-by-step explanation:
find the x and y intercepts of the graph -6x + 4y = 32 state your answers as while numbers or as improper fractions in simplest form
Answer:
x intercept = -5.33
y intercept = 8
Step-by-step explanation:
The given equation is ,
⇒ -6x + 4y = 32 ,
The standard form of the Intercept form is ,
⇒ x/a + y/b = 1 , where
a is x interceptb is y intercept .• Converting the equation :-
⇒ 2( -3x + 2y ) = 32
⇒ -3x + 2y = 16
⇒ -3x + 2y / 16 = 1
⇒ (-3x)/16 + 2y/16 = 1
⇒ -3x/16 + y/8 = 1
Convert -3x/16 in x/a form⇒ x/-5.33 + y/8 = 1 .
Therefore ,
x intercept = -5.33 y intercept = 8An electronics store purchases

Solve the Following Questions. (show your work)
Part A.) A planet’s diameter is approximately 27,340,000 meters. What is that number in scientific notation?
Part B.) What is the product of 3.20 × 10–5 and 6.5 × 103?
Answer:
A = 2.734*10^7, B = .208
Step-by-step explanation:
A = 2.734*10^7
There are 7 decimal places from 0 to 10 million
B = .208
multiply 3.2 and 6.5, get 20.8, 10^3 * 10^-5 =10^-2
20.8 * 10^-2 = .208

Tom is told by his doctor that he needs to lose 15 pounds if Tom now it's 285 pounds then by what percentage should Tom's week decrease
Answer:
the percentage is 5.56%
Step-by-step explanation:
The computation of the percentage that the tom should decrease is shown below:
As Doctor said tom to reduce 15 pounds
As of now the tom has 285 pounds
So after considering the 15 pounds, it would be
= 285 - 15
= 270 pounds
Now the percentage that should be considered is
= (285 - 270) ÷ (270)
= 5.56%
Hence, the percentage is 5.56%

What is the product of 5/6 * 18/30? Be sure to simplify your answer.
The answer is 113/30.
break down how you get the answer 113/30
please dont use files
Answer:
1/2
Step-by-step explanation:
To multiply fractions, you multiply numerator with numerator and denominator with denominator:
a/b*c/d=(a*c)/(b*d)
5/6*18/30=(5*18)/(6*30)=90/180=9/18=1/2
Therefore, the answer is 1/2. Looks like your answer of 113/30 either is wrong or the problem was not formatted correctly.
