Answer:
x=1/3, x=-2/3
Step-by-step explanation:
9x^2 +6x -3x -2=0
6x and -3x add up to 3x. You need four terms to factor.
Then you factor=
3x(3x+2)-1(3x+2)=0
(3x-1)(3x+2)=0
Then you can make two equations
3x-1=0 and 3x+2=0 because to multiply to get 0, at least one will be 0.
3x-1=0
3x=1
x=1/3
3x+2=0
3x=-2
x=-2/3
So your answers are x=1/3, x=-2/3
hope this helps!

The diameter of a circle is 4 millimeters. What is the circle's circumference?
Answer:
4pi millimeters.
Assuming pi = 3.14159, we can approximate the diameter to be 12.56636mm
Step-by-step explanation:
To get the circumference of a circle, just multiply the diameter by pi
Answer:
C=0.125m
Step-by-step explanation:
C = 2[tex]\pi[/tex]r= (2r)[tex]\pi[/tex] = d[tex]\pi[/tex] = 0.004·[tex]\pi[/tex] = 0.125m

I need help and I’ll give 100 points
Answer:
the student may have made the mistake because the student was paying more attention to how many blocks he was filling in rather than how much he was filling in.
to solve the problem correctly you would just switch the decimals
0.8 > 0.08
0.8 should have 80 blocks filled
0.08 should have 8 blocks filled

What is the equation of the line shown in the graph?
Describe the difference between a bar graph and a circle graph.
Answer:
Unlike most circle graphs, bar graphs compare exact amounts. Circle graphs are used when dealing with percentages, and the percentages of the pieces add up to 100 percent. In a bar graph, however, a scale is used to show the exact amount of each category. ... The bar graph shows the same results but in a different format.
The topology taxi company charges 2.60 for the first quarter of a mile and 0.36 for each additional fifth of a mile. Find a linear function which models the taxi fare F as a function of the number of miles driven m
Answer:
The piecewise function for the taxi fare is:
[tex]F(t) = 2.60\cdot \left(\frac {m}{0.25}\right) ,\, 0\,mi\le m \le 0.25\,mi[/tex]
[tex]F(t) = 2.60 + 0.36\cdot \left(\frac{m}{0.2} \right)[/tex], [tex]m > 0.25\,mi[/tex]
Step-by-step explanation:
We must use the following piecewise function:
(i) The Topology Taxi Company charges 2.60 for the first quarter of a mile:
[tex]F(t) = 2.60\cdot \left(\frac {m}{0.25}\right) ,\, 0\,mi\le m \le 0.25\,mi[/tex] (1)
Where:
[tex]F(t)[/tex] - Taxi fare, in monetary units.
[tex]m[/tex] - Number of miles driven, in miles.
(ii) And 0.36 for each additional fifth of a mile:
[tex]F(t) = 2.60 + 0.36\cdot \left(\frac{m}{0.2} \right)[/tex], [tex]m > 0.25\,mi[/tex] (2)
Evaluate f(x) = 2|x – 5| for f(–5) and f(0).
f(–5) = –20, f(0) = –2
f(–5) = 10, f(0) = 0
f(–5) = 20, f(0) = 10
f(–5) = 12, f(0) = 5
Answer:
f(–5) = 20, f(0) = 10
Step-by-step explanation:
f(-5):
f(-5) = 2|-5 -5|
f(-5) = 2|-10|
f(-5) = 2(10)
f(-5) = 20
f(0):
f(0) = 2|0 - 5|
f(0) = 2|-5|
f(0) = 2(5)
f(0) = 10

Given f (x) = -4x+6, find f (10)
f ( x ) = - 4x + 6
f ( 10 ) = - 4 ( 10 ) + 6
f ( 10 ) = - 40 + 6
f ( 10 ) = - 34
