Answer:
C.–1 and 4
Step-by-step explanation:
Solving the equations y = –x² + 4x and y = x – 4
–x² + 4x = x – 4
x² - 4x + x = 4
x² - 3x = 4
x² - 3x + (3/2)² = 4 + (3/2)²
(x - 3/2)² = 4 + 9/4
= 6.25
x - 3/2 = √6.25 or x - 3/2 = -√6.25
x = 2.5 + 1.5 x = -2.5 + 1.5
= 4 = -1
Answer: C -1 and 4

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

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
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)

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)
What is the value of m in the m + 3/4 = − 3/8
Answer:
M=-9/8
Step-by-step explanation:
-3/8-3/4=-3/8-6/8=-9/8
Answer:
m = -9/8
Step-by-step explanation:
First, let's get m by itself by subtracting 3/4 from both sides:
m = -3/8 - 3/4
The least common denonimator between our two fractions is 8, so we can turn 3/4 into the equivalent fraction 6/8 to subtract our two fractions:
m = -3/8 - 6/8 = -9/8
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
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}
Step-by-step explanation:
Answer: Answer:A=2,4,6,8
