Which step could be used to solve x + 3.6 = negative 1.7 for x in one step? Select two options. Add 3.6 to both sides. Add Negative 3.6 to both sides. Add 1.7 to both sides. Add Negative 1.7 to both sides. Subtract 3.6 from both sides.
Answer:
Subtract 3.6 from both sides.
Step-by-step explanation:
Given
[tex]x + 3.6 = -1.7[/tex]
Required
Solve in one step
There are two ways to go about it.
1. Collect Like Terms
[tex]x + 3.6 = -1.7[/tex]
3.6 and -1.7 are like terms, so the equation becomes
[tex]x = -1.7 - 3.6[/tex]
[tex]x = -5.3[/tex]
2. Subtract 3.6 from both sides
[tex]x + 3.6 = -1.7[/tex]
This becomes
[tex]x + 3.6 - 3.6 = -1.7 - 3.6[/tex]
[tex]x = -5.3[/tex]
Hence, the last option answers the question.
Answer:
Option 2and 5 are correct.
Step-by-step explanation:
-Add -3.6 to both sides
-Subtract 3.6 from both sides

What is -2(3x - 9) + 5x = -10
Answer:
x=28
Step-by-step explanation:
-2(3x-9)+5x =-10
now we times -2 to to the inside of the parenthese
giving us
-6x+18 +5x= -10
add like terms
add -6x and 5x
-1x+18=-10
now we add like terms of the constants
minus 18 on both sides
-1x=-28
now divide by -1
x = 28
Answer:
x = 28
Step-by-step explanation:
First, remove the parentheses by distributing -2.
-6x + 18 + 5x = 10
Next, collect the like terms.
-x + 18 = -10
Next, move the constant to the right-hand side and change its sign.
-x = -10 - 18
Next, calculate the difference
-x = -28
Lastly, change the signs on both sides of the equation.
x = 28
These are the steps to answer this equation.
Compare the function with the parent function. Without graphing, what are the vertex, axis of symmetry, and transformations of the given function?
y = 8x - 21 - 7
Answer:
The parent function is: y = x
First, here we have two types of transformations, and we could define them in a general way as:
if we start with a function f(x)
Vertical dilation/contraction: A vertical dilation/contraction of scale factor A (A is always positive) is written as:
g(x) = A*f(x)
Vertical translation:
We can write a vertical translation of A units upwards as:
g(x) = f(x) + A
And a vertical translations of A units down can be written as:
g(x) = f(x) - A.
In this case, the transformations are:
first, a dilation of scale factor 8.
Then a translation down of 21 units
then another translation down of 7 units.
y = 8*X - 21 - 7
y = 8*x - 28.
As this is a linear equation, there are no axis of symmetry, we only could have a line of symmetry along the same line y = 8*x - 28
Again, as this function is a linear equation there is no vertex.

Answer:
The student had a total of 25 questions on his test.
Step-by-step explanation:
Given that:
Number of questions answered correctly in the test = 20
Percentage scored in the test = 80%
Let,
x be the total number of questions on test.
We know that 80% of the test is 20 questions, therefore,
80% of x = 20
[tex]\frac{80}{100}x=20\\0.8x=20[/tex]
Dividing both sides by 0.8
[tex]\frac{0.8x}{0.8}=\frac{20}{0.8}\\x=25[/tex]
Hence,
The student had a total of 25 questions on his test.

Tickets to a band concert cost $10 each. The equation y = 10x represents total cost, y, of x tickets. Which graph shows ordered pairs represented by this equation?
Answer:
the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.
Step-by-step explanation:
Given the function equation
y = 10xGiven that the cost of each ticket is $10.
It means:
at x = 0, y = 10(0) = 0 ∵ cost of 0 ticket
at x = 1, y = 10(1) = 10 ∵ cost of 1 ticket
at x = 2, y = 10(2) = 20 ∵ cost of 2 tickets
at x = 3, y = 10(3) = 30 ∵ cost of 3 tickets
at x = 4, y = 10(4) = 40 ∵ cost of 4 tickets
at x = 5, y = 10(5) = 50 ∵ cost of 5 tickets
Now, observe the ordered pairs points on the right-hand graph of the first diagram.
This graph has the following ordered pairs:
(0, 0) i.e. at x = 0, y = 10(0) = 0(1, 10) i.e. at x = 1, y = 10(1) = 10 (2, 20) i.e. at x = 2, y = 10(2) = 20 (3, 30) i.e. at x = 3, y = 10(3) = 30 (4, 40) i.e. at x = 4, y = 10(4) = 40 (5, 50) i.e. at x = 5, y = 10(5) = 50Thus, the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.

If f(x)f(x) is an exponential function where f(4.5)=23f(4.5)=23 and f(8)=42f(8)=42, then find the value of f(5.5)f(5.5), to the nearest hundredth.
Answer:
f(5.5)≈27.32
Step-by-step explanation:
The exponential function which satisfy the f(4.5) = 23 and f(8) = 42 will be 10.60([tex]1.19^{x}[/tex]).
What is an exponential function?In mathematics, an exponential function is a relationship of the type y = ax, where x is an independent variable that spans the entire real number line and is expressed as the exponent of a positive number.
Suppose the exponential function is f(x) = a[tex]b^{x}[/tex].
As per the given,
f(4.5) = 23
Put x = 4.5 as
23 = a[tex]b^{4.5}[/tex] (1)
As per the given,
f(8) = 42
Put x = 8 as
42 = ab⁸ (2)
Divide equation (2) by (1) as,
ab⁸ / a[tex]b^{4.5}[/tex] = 42/23
[tex]b^{8-4.5}[/tex] = 42/23
b = 1.19
Again put into (2)
42 = a(1.19)⁸
a = 10.60
Thus, the function will be f(x) = 10.60([tex]1.19^{x}[/tex]).
Hence "The exponential function which satisfy the f(4.5) = 23 and f(8) = 42 will be 10.60([tex]1.19^{x}[/tex])".
