Steps for solving 5(2x - 8) = 20 are shown. 5(2x-8)= 20 10x - 40 = 20 10x - 40+ 40 = 20 + 40 10x = 60 10x 60 10 10 x = 6 Original Equation Which of these is not part of the solution process?
Answers
Answer:
(d) Using the commutative property
Step-by-step explanation:
Given
The above steps
Required
Which is not part of the process
We have:
[tex]5(2x-8)= 20[/tex]
[tex]10x - 40 = 20[/tex]
[tex]10x - 40+ 40 = 20 + 40[/tex]
[tex]10x = 60[/tex]
[tex]\frac{10x}{10} = \frac{60}{10}[/tex]
[tex]x = 6[/tex]
Comparing the above steps with the given list of options, we can see that the commutative property is not applied at all.
Other properties are:
[tex]5(2x-8)= 20[/tex] ---- Distributive
[tex]10x - 40+ 40 = 20 + 40[/tex] ---- Like terms
[tex]\frac{10x}{10} = \frac{60}{10}[/tex] --- Isolating the variable

What value of x makes the 2 triangles congruent by HL? Find the length of CB
Answers
Step-by-step explanation:
here's your solution
==> Both traingle are congruent
==> BC = BD. [ c.p.c.t ]
==> x + 8 = 3x - 14
==> x - 3x = - 14 - 8
==> - 2x = - 22
==> x = 22/2
==> x = 11
now CB = x + 8 = 11 + 8
CB = 19

Hilary measured the depth of the snow in her front yard for 7 days. An equation for Hilary's data is y = − 0.5 x + 8 . Let x represent the number of days, and y represent the depth of the snow in inches.
Answers
Answer:
4.5 inches
Step-by-step explanation:
Given:
y = -0.5x + 8
Where,
x = the number of days
y = the depth of the snow in inches
Find y when x = 7
y = -0.5x + 8
= -0.5(7) + 8
= -3.5 + 8
= 4.5
y = 4.5 inches
The depth of the snow in Hillary's front yard for 7 days is 4.5 inches

Is it linear , quadratic, exponential
Answers
Answer:
Exponential
Step-by-step explanation:
So lets look at the table.
When x = 1, y = 3
When x = 2, y = 9.
Hmmm, this doenst seem like x+number=y. It doesnt seem like a quadratic, where the values go up, then down, then up again. Or vise versa.
So this rules out linear and quadratic, for the x doesnt change by a constant, or change the direction of y.
This leaves exponential or none of the above.
When x = 3, y = 27
When x = 4, y = 81
This seems like a exponent, since:
3 to the first power is 3
3 to the second power is 9
3 to the third power is 27
and 3 to the fourth power is 81
Answer:
exponential function

Thomas paid $4.25 for three apples and four oranges. Five apples and two oranges cost Casey $4.75. Let x represent the number of apples and y represent the number of oranges. Which system of equations represents this situation? A $~3x+4y=4.75~$ $~5x+2y=4.25~$ B 3x+4y=4.25 5x+2y=4.75 C 4x+3y=4.75 2x+5y=4.25 D 4x+3y=4.25 2x+5y=4.75
Answers
Answer:
B
Step-by-step explanation:
For the given situation, system of equations is represented by
3x + 4y = 4.25
5x + 2y = 4.75
What is system of equations?"A system of equations is a finite set of equations for which we find the common solution."
According to question,
x represents number of apples
y represents number of oranges.
Two situations are given for which we need to find out which system of equations it represents.
Situation 1 : Thomas paid $4.25 for the three apples and four oranges , which can be represented by equation:
3x + 4y = 4.25
Situation 2: Casey paid $4.75 for five apples and two oranges, which can be represented by equation:
5x + 2y = 4.75
Hence we can conclude that Option B is correct.

The equation of a parabola is y=x^2–4x+13. Write the equation in vertex form.
Simplify any fractions.
Answers
Answer:
y = (x - 2)² + 9
Step-by-step explanation:
To obtain the equation in vertex form use the method of completing the square.
Add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = x² + 2(- 2)x + 4 - 4 + 13
= (x - 2)² + 9 ← in vertex form
Answer:
vertex form : y=(x-2)^2+9
Step-by-step explanation:
To convert a parabola from standard form y=x^2-4x+13 to vertex form, we complete the square.
first, complete the square using the x-terms, use the constant term to adjust and make a perfect square.
y= x^2-4x+4 + 9
Factor the first three terms on the right-hand side.
y=(x-2)^2 + 9
the resulting express is then the vertex form, which means that
the vertex is at (x-2) = 0, x=2, and at y=9.
