Answer:
x = 1/4
Step-by-step explanation:
Solve for x:
1 - 2 (1 - 2 x) = 0
Hint: | Distribute -2 over 1 - 2 x.
-2 (1 - 2 x) = 4 x - 2:
4 x - 2 + 1 = 0
Hint: | Group like terms in 4 x - 2 + 1.
Grouping like terms, 4 x - 2 + 1 = 4 x + (1 - 2):
4 x + (1 - 2) = 0
Hint: | Evaluate 1 - 2.
1 - 2 = -1:
4 x + -1 = 0
Hint: | Isolate terms with x to the left hand side.
Add 1 to both sides:
4 x + (1 - 1) = 1
Hint: | Look for the difference of two identical terms.
1 - 1 = 0:
4 x = 1
Hint: | Solve for x.
Divide both sides by 4:
Answer: x = 1/4

DONE
Step-by-step explanation:
when x >0
y=/0+7 +5
y=8
(0,8)
when x>7
y= /7+7 +5
y= 9
(7,9)

If segment DF is an angle bisector, solve for x
Answer:
x = 19
Step-by-step explanation:
Since DF is an angle bisector then it divides the opposite sides into segments that are proportional to the other 2 sides, that is
[tex]\frac{DE}{DG}[/tex] = [tex]\frac{EF}{GF}[/tex] , substitute values
[tex]\frac{25}{22.5}[/tex] = [tex]\frac{x-9}{9}[/tex] ( cross- multiply )
22.5(x - 9) = 225 ( divide both sides by 22.5 )
x - 9 = 10 ( add 9 to both sides )
x = 19

The point P(2,-3) is translated by the rule (x,y) —> (x+4,y-2) and then reflected over the x-axis, what are the coordinates of P’’??
Answer: (6, 5)
Step-by-step explanation: (2+4,-3-2) = (6, -5)
After reflection on x - axis, the y value changes the sign from negative to positive (to the opposite) : (6,5)
Jose paid $1.12 for a dozen eggs at Target. How much would Jose have to pay for 18 eggs?
Answer:
56.16
Step-by-step explanation: All you do is just multiply
Answer:
$1.67
Step-by-step explanation:
Given it's $1.12 for 12 eggs, we divide 1.12 by 12 to see how much it cost for 1 egg
1.12/12 = 0.093
so 0.093 cents for 1 egg
0.093x18 eggs = 1.674 = $1.67

John called a plumber to fix a leak in his bathroom. The plumber charged $30 to come to the house and $25 an hour while fixing the leak. If the final bill
was $105. how many hours was the plumber at John's house?
Answer:
30 subtracted from 105 leaves u with 75 so divide that with 25 & he took abt 3 hrs
He lives 50 m from a park.
The park is 275 m long and 200 m wide.
How far does he run in total?
We have to find the perimeter of the park and then add 50m to that
Perimeter = 2(l+b)
= 2(275+200)
= 2* 475
= 950m
Therefore: Total distance covered = 950+50 = 1000 m(1km)

write the set in builder form. A{2,4,6,8}
Answer:A=2,4,6,8
One way of writing this in set builder notation could be:
A={x|2≤x≤8|x2∈N}
Which can be interpreted as:
The set A is the set of any x such that 2≤x≤8 such that half of x is a natural number ( N ).
There are many ways of writing sets in set builder notation. Which is why it can be a little confusing to learn (the syntax) at first. Once you understand what all these new mathematical symbols mean (i.e. ∈ , | , N ), it becomes much easier to “read as a sentence”.
Here are a few more ways of writing the set A=2,4,6,8 in set builder notation:
A={x|2≤x≤8|x∈2⋅N}
A={x|(x−2)(x−4)(x−6)(x−8)=0}
A={x|x=2p|p∈{1,2,3,4}}
A={x∈N|mod(x,2)=0|x≤8}
