PLS help me!!! (EASY) (CORRECT Answer GETS BRAINLIEST + 16 points!!)
Answer:
y = 2x + 2
Step-by-step explanation:
First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.
(0, 2) & (6, 14)
Plug in these values:
(14 - 2) / (6 - 0)
Simplify the parentheses.
= (12) / (6)
Simplify the fraction.
12/6
= 2
This is your slope.
Now plug this into the standard slope-intercept equation: y = mx + b
y = 2x + b
b is the y-intercept, or the value of y when x = 0. If y=we look at the table, we can see that when x = 0, y = 2.
Therefore, our b-value is 2.
Plug this into our equation.
y = 2x + 2

(Answer is not -3)
Answer:
Look below.
Step-by-step explanation:
K(x)=x^2 isnt graphed but P(x)=x^2+n is. We could use this information to figure out what n is. In a quadratic function we always have the same points unless we are transforming it.
X Y
2 4
1 1
0 0
-1 1
-2 4
If we compare what the points were in the parent function to what is shown now we could see that the graph went down 6. From this information we can conclude that n must be -6.
A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25, point, 25 meters thick.
Let y represent the ice sheet's thickness (in meters) after x weeks.

Answer: 16p^8q^4r^8 The yellow one
Step-by-step explanation:
Step 1: Use Multiplication Distributive Property: (xy)^a = x^a y^a. So 4^2p^2(q^3)(r^4)^2
Step 2: Simplify 4^2 to 16. So 16p^2(q^3)^2(r^4)^2
Step 3: Use Power Rule: (x^a)^b=x^ab. So 16p^2q^6(r^4)^2
Step 4: Use Power Rule: (x^a)^b=x^ab. So the answer is 16p^2q^6r^8. The yellow one

The volume of a mini-basketball is approximately 4846.59 cubic centimeters. What is the approximate radius of a mini-basketball?
A
10.5 cm
B
11.5 cm
C
21 cm
D
23 cm
Answer:
A
Step-by-step explanation:
4/3 pi r3= 4846.59*3/4/pi=1157.625
so r3= 1157.625
so taking cube root on both sides we get
10.5 which is A

In 2004 kyle was 8 years old . In 2006 kyle was was four year older than his cousin albert. a.how old was albert in 2004. b. in what year was albert born
Answer:
Albert was born in the year 2000!
Step-by-step explanation:
2006 Kyle is 10
10 - 4 = 6
So, Albert was 6 years old in 2006
6 - 6 = 0
2006 - 6 = 2000
Kyle was born in the year 2000.
Answer:
A) 4 years old
B) 2000
Step-by-step explanation:
A) 2004 Kyle was 8 years old. Two years pass which makes Kyle 10. Kyle is 4 years older than his cousin 10-4 equal 6. Albert was 6 in 2006. 6-2 equal 4
B) Albert is 6 (2006) which means he was born in 2000.

Step-by-step explanation:

B) True
C) True
D) False Solution is actually (-3, -3)
work below
Note: Used Elimination Method
Multiply the first equation by -2,and multiply the second equation by 1.
−2(−2x+y=3)
1(3x+2y=−15)
Becomes:
4x−2y=−6
3x+2y=−15
Add these equations to eliminate y:
7x=−21
Then we solve 7x = −21 for x:
7x = −21
7 7
(we Divide both sides by 7)
x=−3
Now that we've found x let's put it back in to solve for y.
Put down an original equation:
−2x+y=3
Substitute−3 for x in−2x+y=3:
(−2)(−3)+y=3
y+6=3(Simplify both sides of the equation)
y+6+−6=3+−6(Add -6 to both sides)
y= −3
Solution
(-3, -3)
SOLVE THESE TWO FOR BRAINLY PLSSSS!!!!!!!!
Answer: 1) D
2) A
Step-by-step explanation: plz mark me brainliest
Answer:
1) C) 2) B)
Step-by-step explanation:
First one is just times them together get 12root(a^2b^2) = 12ab.
Second question, you use equation 1 to minus equation 2 get 2x = 6, then x = 3, then substitute it into either equation, for example the first one get -7*3 + 5y = 24, then solve for y, can get y = 9, so B) is correct answer.

Step-by-step explanation:
On a certain hot summer's day, 218 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $349.75.
How many children and how many adults swam at the public pool that day?
Answer:
We call x the number of children and y the number of adults
We have system of equations
x + y = 218 (1)
1.25x + 2y = 349.75 (2)
(1) => x = 218 - y. Replace x in (2) 1.25 (218-y) + 2y = 349.75
=> y = 103 replace y in (1) x = 218-103 = 115
Children and how many adults swam at the public pool that day is : 115 and 103

The edge of a cube is 4 inches.
The area of a cross section perpendicular to one face is
square inches, and its perimeter is
inches
Answer:
Sketch of a cube with side = 4 in as shown.
The shaded area is perpendicular to the right and left vertical faces of the cube, so the cross section is a square with each side equal to 4 in.
The area of the cross section is
4*4 = 16 in²
The perimeter of the cross section is
4+4+4+4 = 16 in.

A radio disc jockey has 8 songs on this upcoming hour's playlist: 2 are rock songs, 4 are reggae songs, and 2 are country songs. The disc jockey randomly chooses the first song to play, and then she randomly chooses the second song from the remaining ones. What is the probability that both songs are reggae songs? Write your answer as a fraction in simplest form.
Answer:
[tex] \displaystyle \frac{1}{28} [/tex]
Step-by-step explanation:
we are given 8 songs
2 are rock. 4 are reggae, 2 are country
we want to figure out the probability of getting both reggae songs
notice that, they aren't replacing thus it's an independent probability
recall that,
[tex] \displaystyle \rm P(A \: \text{and} \: B) = P(A) \times P(B \mid A)[/tex]
P(A) represents the chance of getting our subject first time and P(B|A) represents the chance of getting the same subject second time
let's figure out P(A)
we have 2 reggae songs
and total 8 songs
therefore
[tex] \displaystyle\rm P(A) = \frac{2}{8} = \frac{1}{4} [/tex]
let's figure out P(B|A)
since we took a reggae song before now we have only a reggae song
and total 8-1=7
therefore
[tex] \displaystyle \rm P(B\mid A) = \frac{1}{7} [/tex]
Altogether
[tex] \displaystyle \rm P(A \: \text{and} \: B) = \frac{1}{4} \times \frac{1}{7} [/tex]
simplify multiplication:
[tex] \displaystyle \rm P(A \: \text{and} \: B) = \frac{1}{28} [/tex]
And we are done!

Find the circumference and area of the circle to the nearest hundredth. Use 3.14 for π. Round to the nearest hundredth if necessary.
56 is the cm.
Answer:
56÷2=28
Circumference=2×3.142×r
c= 2×3.142×28=175.952
hundredth =175.95cm
Area=3.142×r^2
A= 3.142×28^2=2463.328
hundredth =2463.33cm^2
just do number 3 quick please
Answer:
Step-by-step explanation:
Sin A = [tex]\frac{opposite side}{hypotenuse}=\frac{5}{13}\\\\[/tex]
Cos A = [tex]\frac{Adjacent side}{hypotenuse}=\frac{12}{13}[/tex]
Tan A = [tex]\frac{opposite side}{adjacent side}=\frac{5}{12}[/tex]
A = tan⁻¹ (5/12) = 22.61°
Answer:
Step-by-step explanation:
a) Sin A = opposite/hypothenuse
Sin A = 5/13 ≈ 0.3846..
b) Cos A = adjacent/hypothenus
Cos A = 12/13 ≈ 0.9230..
c) Tan A = opposite/adjacent
Tan A = 5/12 ≈ 0.4166..
d) we will use the inverse Sine function
< A = sin^-1(5/13)
< A = sin^-1(0.3846) ≈ 22.62°
P.S. You can use any of the three inverse functions to find the angle: sin^-1 | cos^-1 | tan^-1
