Answers

Answer 1
y = -1.5x + 5.7
y = 0.5x + 0.3

-1.5x + 5.7 = 0.5x + 0.3
-1.5x - 0.5x = 0.3 - 5.7
-2x = - 5.4
x = -5.4/-2
x = 2.7

y = 0.5x + 0.3
y = 0.5(2.7) + 0.3
y = 1.35 + 0.3
y = 1.65

solution is (2.7, 1.65)

Sophia is more likely to be correct because the x coordinate is between 2 and 3 and the y coordinate is in between 1 and 2

B is the correct answer.

If the population of Town B is 50% greater than the population of Town A and the populations of Town C is 20% greater than the population of Town A, then what percent greater is the population of Town B tan the population of Town C

Answers

Let
A = population of town A,
B = population of town B,
C = population of town C.

Because the population of town B is 50% greater than that of town A,
B = 1.5A                    (1)

Because the population of town C is 20% greater than that of town A,
C = 1.2A                  (2)

From (1), obtain
A = B/1.5 = (2/3)B        (3)

Substitute (3) into (2).
C = 1.2*(2/3)*B = 0.8B
Divide each side by 0.8.
1.25C = B
This result means that B is 25% greater than C.

Which best describes the range of the function f(x) = 2(1/4) after it has been reflected over the y-axis? all real numbers all real numbers less than 0 all real numbers greater than 0 all real numbers less than or equal to 0

Answers

your answer should be C 
all numbers greater than 0

Answer:

All real numbers greater than 0.

Step-by-step explanation:

We have the function, [tex]f(x) = 2(\frac{1}{4})^{x}[/tex].

'Reflection over y-axis means to flip the graph over y-axis', which changes the function by f(x) becomes f(-x).

So, after reflection, the given function transforms into,

[tex]g(x)=f(-x)[/tex]

i.e. [tex]g(x)=2(\frac{1}{4})^{-x}[/tex]

According to the graph of the function g(x), we see that,

Range of [tex]g(x)=2(\frac{1}{4})^{-x}[/tex] is the 'Set of all real non-negative numbers' i.e. {x | x > 0} i.e. [tex](0,\infty)[/tex]

Answers

[tex]f(q+1)=2(q+1)-4=2q+2-4=2q-2[/tex]

If the function f(x) = 2x-4, the function f(q + 1) = 2q - 2

What is a function?

A function is a mathematical equation that shows the relationship between two variables.

Since if f(x)=2x-4, to find f(q+1), we proceed as follows.

Since we have the function  f(x) = 2x - 4, and we want to find f(q + 1). To find the function f(q + 1), we substitute x = q + 1 into the equation. so, we have that

f(x) = 2x - 4

When x = q + 1, we have that

f(x) = 2x - 4

f(q + 1) = 2(q + 1) - 4

Expanding the brackets, we have that

f(q + 1) = 2q + 2 - 4

= 2q - 2

So, f(q + 1) = 2q - 2

classify the following triangle . check all that apply

Answers

One of the angles is more than 90 degrees  ⇒  Obtuse

Two equal sides  ⇒ Isosceles

Answer:

Option (a) and (d) is correct.

The given triangle is obtuse and isosceles.

Step-by-step explanation:

Given : A triangle with measure of one angle is 120° and two legs of the triangle are given equal in length.

We will have to choose the correct classification for the given triangle.

For a triangle if the measure of one the angles is

1) less than 90 then it is acute triangle ,

2) equal to 90 then right triangle

3) greater to 90 then obtuse triangle

Since the measure  of one angle of the triangle is 120° > 90° Thus, the given triangle is obtuse.

For a triangle if all the three sides are equal then it is equilateral triangle, if two sides are equal then it is isosceles and if no side is equal then it is scalene.

Since, for the given triangle, the two legs of the triangle are given equal in length so it is an isosceles triangle.

Thus, the given triangle is obtuse and isosceles.

Hope I'm able to help you.

Answer:

30.76 [tex]ft^{2}[/tex]

Step-by-step explanation:

To calculate the circumference of a circle you just have to multiply the diameter by pi.

C= D*[tex]\pi[/tex]

And in order to calculate the value of the diameter you have to clear the formula for the area.

A= [tex]r^{2} *\pi[/tex]

r=[tex]\sqrt{\frac{24 \pi }{\pi } }[/tex]

r=[tex]\sqrt{24}[/tex]

r=4,89

Answers

Seeming how it's just text and I can't determine what part A is talking about I'll make a new table.

Part A:(This table is a three by three table, with the first top two sections being liked apple juice and didn't like apple juice, and the first left two sections being liked orange juice and didn't like orange juice. The end sections are totals.)


         AJ   No  TotalOJ    8     20   28
No    27   45   72
Total 35   55   100

Part B:
(What percentage of the total people did not like either apple or orange juice?)

25 people did not like either apple or orange juice so 25/100 is 25%.

Part C:(Do the people surveyed have more dislike for apple juice than orange juice? Justify your answer.)

There were a total of 28 people that liked orange juice against a total of 35 people that liked apple juice, so it is safe to say that out of the 100 surveyed there was more dislike for orange juice than apple juice.

Answer:

Part A: A = 8

B = 20

C = 28

D = 35  

E = 37

F = 72

G = 43

H = 57

I = 200

Part B: 18.5%

Part C:

D = People who do not like Orange Juice

B = People who do not like Apple Juice

I use the values of B and D because these are the values that represent dislike for that juice, and also because adding them together creates a value for not liking either juice.

D = 35

B = 20

So there is a greater dislike for Orange Juice.

b=21/28
a=8b=6.
Using the 2nd and 3rd you have:

4a-4b=21

4a=21+4b

a=(21+4b)/4

now using 1st and 2nd

3(21+4b)/4+4b=4(21+4b)/4-4b

(63+12b+16b)/4=(84+16b-16b)/4

63+28b=84  

28b=21

b=21/28

b=3/4
