Sonia graphs the equations y = –x2 + 4x and y = x – 4 to solve the equation –x2 + 4x = x – 4. Her graph is shown below.

Answers

Answer 1

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

Using a truck, Mr. Salazar needs to haul (4.2 tons) of gravel from a quarry to his house. His truck can hau (3/5 tons) of gravel at one time. What is the least number of trips Mr. Salazar will need to make from the quarry to his house?
A.7
B.8
C.6
D.12​

Answers

4.2 is also equal to 42/10 which is equal to 21/5. In order to find how many trips you will be dividing fractions (21/5) / (3/5). Although this may seems difficult, because the denominators are the same, it simplifies to 21/3 which is equal to 7 (A)

Jose paid $1.12 for a dozen eggs at Target. How much would Jose have to pay for 18 eggs?

Answers

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?

Answers

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)

What is the value of m in the m + 3/4 = − 3/8

Answers

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

Answers

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}​

Answers

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}
