A because u should have gotten a 3x after adding them together since u do what is inside the () before anything
fionaferlich1 avatar
3+x does not equal 3x
joshuasalazar697 avatar
y not
fionaferlich1 avatar
because 3x equals x times x times x not 3+x
joshuasalazar697 avatar
but why is it d
joshuasalazar697 avatar
they did it right u have to divide it from the right to the left
fionaferlich1 avatar
a rule of inequalities is when you divide by a negative the sign switches. so because u had to divide the entire thing by -6 it should be x is greater than -1
joshuasalazar697 avatar
no u have to divide it by positive 6 cause u are taking it the 6 from the right and moving it under the 6 from the left wich u would divide
fionaferlich1 avatar
u always divide by the coefficient of x and that's -6
joshuasalazar697 avatar
no cause since u moved all the letters to the right and all the lone numbers to the left u have to take that last one and divide it from the one with the x
fionaferlich1 avatar
the one with the x is the coefficient of x which is -6
joshuasalazar697 avatar
yeah i know that ut u don't divide the 6 from the -6x like u gonna divide -6x by 6
joshuasalazar697 avatar
also if i am wrong what happened to the 3 and why did it turn to an 18
fionaferlich1 avatar
so say that's what you're supposed to do (which it is ) but then u would get -x>1 and x must be positive
joshuasalazar697 avatar
i should have paid attention in algebra no wonder I don't get geometry but geometry is way easier
joshuasalazar697 avatar
i see what u are getting to now
joshuasalazar697 avatar
still don't see how 3 turned into 18

The given function, f(x) = x, and the function with an input of f(x - 3), which is a transformation of the function f(x), moving it three places to the right, gives the points on the graph of the function as the option;
(negative 1, negative 4), (0, negative 3), (3, 0)
What is the transformation of a function?The transformation of a function involves moving the curve or line that represents the function either left, right, down, or up, reflect the graph or compress or expand the curve of the graph of the function.
The given graph is for the function is f(x) = x, the required graph is the graph of the function, f(x - 3), which is evaluated as follows;
Given f(x) = x, we have, f(x - 3) = x - 3
The table of values for both functions is presented as follows:
x; -4, -3, -2, -1, 0, [tex]{}[/tex]1, 2, 3, 4, 5
f(x) [tex]{}[/tex] -4, -3, -2, -1, 0, 1, 2, 3, 4, 5

From the above table of values, the points on the function, f(x - 3) are; (-1, -4), (0, -3), (3, 0)
The option which gives the points on the graph that shows the function f(x) with an output of f(x - 3) is therefore;

If A < B, then 1/A > 1/B. Applying the reciprocal flips the inequality sign.
For example, if 2 < 3, then 1/2 > 1/3. It might help to look at the decimal representations
1/2 = 0.500
1/3 = 0.333
We see that 1/2 is larger.

The sum of three consecutive numbers is 519. What are the three numbers?
Answers
Answer:
El primer número llamaremos = x
El segundo número llamaremos = x + 1
El tercer número llamaremos = x + 2
Calculamos
x + (x + 1) + (x + 2) = 519
x + x + 1 + x + 2 = 519
x + x + x + 1 + 2 = 519
3x + 3 = 519
3x = 519 - 3
3x = 516
x = 516/3
x = 172
El valor de "x" lo reemplazamos en: (x + 1 y x + 2)
x + 1 = 172 + 1 = 173
x + 2 = 172 + 2 = 174

Answer:
1. 30(8.75) + 11t = 400
2. 12.5 hours
Step-by-step explanation:
1. What is given is you work for 30 hours per week at a gas station for $8.75 an hour. You also work as a landscaper for $11 an hour. You want to a make a total of $400 per week.
30 hours and $8.75 an hour would be equivalent to 30(8.75)
We don’t know how many hours you work as a landscaper but you earn $11 an hour, which is equivalent to 11t
Finally, you want to earn a total of $400 a week, which means the sum equals 400
30(8.75) + 11t = 400
2. 30(8.75) = 262.5
400 - 262.5 = 137.5
137.5 / 11 = 12.5
Brianne is making apple pies. She has 2 1/2 pounds of apples. Brianne estimates she can make 3 pies with no apples left over. How many pounds of apples will go into each pie?
Answers
2 1/2 converted to improper fraction =
2 1/2 = 5/2
5/2 divided into 3 pies
(5/2) / (3/1) —> {whole number 3 converted to improper fraction 3/1}
(5/2) x (1/3) —> {to divide a fraction, multiply by the reciprocal}
(5/2) x (1/3)=5/6
Answer= 5/6 of a pound of apples goes into each pie
0.833 pound of apples go into each pie.
Given Brianne has 2 and half pounds of apples.
she can make 3 pies with no apples left.
Now total quantity of apples she has is 2.5 pound.
Since she can make 3 apple pies with 2.5 pound of apples, so each pie has equal amount of apples.
Now each pie has [tex]\frac{2.5}{3} =0.833[/tex] pounds of apples.
Hence 0.833 pound of apples go into each pie.

Write an equation in slope intercept form with the given information.
Slope = 4 and goes through point (1,8)
(Please help me)
Answers
Answer:
y= 4x +4
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is 4, m= 4.
Substitute m= 4 into the equation:
y= 4x +c
To find the value of c, substitute a pair of coordinates.
When x= 1, y= 8,
8= 4(1) +c
8= 4 +c
c= 8 -4 (-4 on both sides)
c= 4 (simplify)
Thus, the equation is y= 4x +4.

f(x) = 3x - 3
Step-by-step explanation:
First, the slope of the line has to be the same for it to be parallel, so the slope(coefficient of x) of the equation is 3.
Next, to make it pass through that specific point, we need to add/subtract a number to make the equation cross that point.
f(x) = 3x at x = 2 evaluates as 6, but the equation needs to pass through the point (2, 3), so we subtract 3 from the equation, leaving us with f(x) = 3x-3.

Bastian was able to map triangle ABC onto triangle A'B'C' using a reflection, rotation, and a dilation. Then Bastian concluded that he was able to map triangle ABC onto triangle A'B'C' using a sequence of rigid transformations and dilations, so the triangles are similar. What error did Bastian make in his conclusion?
Bastian used a rotation, so the triangles aren't similar.
Bastian used a combination of similarity transformations, which can produce a non-similar result.
There is no error. This is a correct conclusion.
Bastian used a dilation, which does not preserve similarity.
