Answer:
x = 56
Step-by-step explanation:
Step 1: Write out equation
x + 20 + x + 48 = 180
Step 2: Combine like terms (x)
2x + 20 + 48 = 180
Step 3: Combine like terms (constants)
2x + 68 = 180
Step 4: Subtract 68 on both sides
2x = 112
Step 5: Divide both sides by 2
x = 56
The current price for gasoline is $3.049 per gallon. A customer puts 7.45 gallons in her car. How much does she pay for the gas? Round your answer to the nearest cent.
Answer:
$22.72 for gas
Step-by-step explanation:
If each gallon costs $3.049, then we multiply the cost of each gallon by 7.45
3.049 x 7.45 = 22.71505
As the question asks us to round to the nearest cent in 22.71505, we would round up.
Your answer is $22.75 for gas

if
f(x)=x^2+2x-4
and
g(x)=3x+1
find
f(g(x))=__x^2+__x+__
Step-by-step explanation:
f(x) = x² + 2x - 4
g(x) = 3x + 1
f(g(x)) = f(3x + 1)
f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4
= 9x² + 6x + 1 + 6x + 2 - 4
= 9x² + 12x -1

An astronaut is returning to earth in a spacecraft. If the spacecraft is descending at a rate of 13.81 kilometres per minute,what will be its change in height after 5 and 1/2 minutes.Round your answer to the nearest kilometer.
Answer:
-76
Step-by-step explanation:
I give credit to the other people that said it, I am not the smart one her lol
The change in height after 5 and 1/2 minutes to the nearest kilometer will be 75.955
What is the fundamental principle of multiplication?If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
we have been given that the spacecraft is descending at a rate of 13.81 kilometres per minute, then change in height after 5 and 1/2 minutes will be;
WE can see that the astronaut is descending 13.81 km each minute, so multiply that by 5 and a half minutes .
Then multiply 5 and 1/2 minutes by 13.81,
Speed = distance / times
Rate = 11/2 x 13.81
Rate = 75.955
Therefore, The change in height after 5 and 1/2 minutes to the nearest kilometer will be 75.955

5. Write the equation of the line graphed below.
Answer:
y=2x+3
Step-by-step explanation:the rise over run is 2/1 indicating that the slope is 2. the line also passes through 3 which means the y intercept is 3.
x = 7 + 3y
5x + 6y = 14
Which ordered pair (x,y) is the solution to the system of equations above?
x = 7 + 3y
or, x - 3y - 7 = 0 ........ (i)
5x + 6y = 14
or, 5x + 6y - 14 = 0 .........(ii)
To Find:The value of x and y.
Solution:By dividing eq. ii by 2, we get
5/2x + 3y - 7 = 0 ........ (iii)
By adding eq. i and eq. iii, we get
15/2x = 0
or, x = 0 ........(iv)
By putting eq.(iv) in eq. (i), we get
0 - 3y - 7 = 0
or, -3y = 7
or, y = -7/3
Answer: ( 0, -7/3 )The value of x and y is 0 and -7/3 respectively.
Solve for x in simplest form 1=1/3 (10x−3)
Answer:
x = 3/5
Step-by-step explanation:
1=1/3 (10x−3)
Multiply each side by 3
3=3*1/3 (10x−3)
3= (10x−3)
Add 3 to each side
3+3= (10x−3+3)
6 = 10x
Divide each side by 10
6/10 = 10x/10

Which statement describes g(x) as a transformation of
f(x) and identifies an equation for g(x)?
Vertical stretch followed by a translation 1 unit left, so
g(x) = f*(x + 1)).
O Vertical stretch followed by a translation 1 unit right,
so g(x) = 1 + x = 1)).
O Horizontal stretch followed by a translation 1 unit left,
so g(x) = (3x + 2).
O Horizontal stretch followed by a translation 1 unit
right, so g(x) = (4 x - 1)
Answer:
The correct option is;
Horizontal stretch followed by a translation 1 unit left so g(x) = (3·x + 2)
Step-by-step explanation:
In geometric transformation, a dilation involves the increase in the dimension of the distances between points by a given scale factor.
Therefore, with regards to the question, a dilation can be represented by the product of the initial dimension, x, by a variable, such as an integer
A translation right is represented by an addition to the x value, while a translation left is represented by subtraction from the x value
Therefore, whereby f(x) = x + 1
An horizontal stretch of 3 will be 3 × (x + 1) = 3·x + 3
Followed by an a translation 1 unit left will be;
3·x + 3 - 1 = 3·x + 2;
Therefore;
g(x) = (3·x + 2).
