Answer:
12.9x-9
Step-by-step explanation:
First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self beacuse thers no other like terms.
Anwer
12.9x−9 :)
5.3x+−9+7.6x
Combine Like Terms:
=5.3x+−9+7.6x
=(5.3x+7.6x)+(−9)
=12.9x+−
For a given input value q, the function f outputs a value r to satisfy the following equation.
11q – 4= 3r - 6
Write a formula for f(q) in terms of q.
f(q) =
Answer:
22
Step-by-step explanation:
Answer:
{11q+2/3}
Step-by-step explanation:
Take out r
What is the answer?
Answer:
clockwise
Q= (5,-2)
R= (-1,-3)
S= (0,0)
T= (3,-2)
counterclockwise
Q= (-5,2)
R= (1,3)
S= (0,0)
T= (-3,-2)
Step-by-step explanation:
this might not be right im a little rusty on my transformations but here goes nothing.
i dont know if this is a clockwise or a counter clockwise rotation so ill do both options.
clockwise (x,y) - (y,-x)
q=(2,5) - (5,-2)
r=(3,-1) - (-1,-3)
s=(0,0) - (0,0)
t=(-2,3) - (3,2)
counterclockwise (x,y) - (-y,x)
q=(2,5) - (-5,2)
r=(3,-1) - (1,3)
s=(0,0) - (0,0)
t=(-2,3) - (-3,-2)

Scientists find a wooden spoon and they want to use Carbon dating to out how old it is. If the amount of carbon left is 85% of its original amount, how old this artifact? (Note here that we are actually finding the age of the wood from which the spoon was made
Answer:
1,336 year (Approx)
Step-by-step explanation:
Half life of carbon 14 = 5,700 year
Equation used for carbon dating:
t = [5,700/In2]ln[N]
t = [5,700/In2]ln[85%]
t = [5,700/In2]ln[0.85]
t = 1,336 year (Approx)

In parallelogram PQRS if m
Answer:
m∠RSP = 130°
Step-by-step explanation:
In parallelogram,opposite angles are equal.
m∠RSP = m∠PQR
m∠RSP = 130°
Answer:
∠RSP=130
Step-by-step explanation:
It is given that ∠PQR = 130°
∴∠RSP = 130° (vertically opposite angles are equal in a parallelogram)
A bowling alley charges $2.50 per game plus $4 to rent shoes. A second bowling alley charges $4 per game plus $1 to rent shoes. How many games would a
person have to play for the two bowling alleys to cost the same amount?
Answer:
The person would have to play 2 games for the two bowling alleys to cost the same amount
Step-by-step explanation:
Assume that the number of games that makes the two costs equal is x
∵ A bowling alley charges $2.50 per game plus $4 to rent shoes
∵ The number of games is x
∴ The cost = 2.50x + 4
∵ A second bowling alley charges $4 per game plus $1 to rent shoes
∵ The number of games is x
∴ The cost = 4x + 1
∵ They have the same cost
→ Equate the 2 expressions above
∴ 4x + 1 = 2.50x + 4
→ Subtract 2.50x from both sides
∵ 4x - 2.50x + 1 = 2.50x - 2.50x + 4
∴ 1.50x + 1 = 4
→ Subtract 1 from both sides
∵ 1.50x + 1 - 1 = 4 - 1
∴ 1.50x = 3
→ Divide both sides by 1.50
∴ x = 2
∴ The person would have to play 2 games for the two bowling alleys to
cost the same amount

Part 1: Simplify √250
Part 2: Classify the number above as rational or irrational
Level 3 (Proficient: 85%)
Part 1: Simplify √150x*5
Part 2: Is the follow expression rational or irrational and why? 2√4+7
Level 4 (Distinguished: 100%)
Part 1: Simplify 13√750x*5 y*8
Part 2: Create two unique expressions each involving 1 square root and at least 1 operation (adding, subtracting, multiplying, dividing). Make 1 results in a rational number and the other result in an irrational number. Explain your reasoning for both.
Explanation:
Level 2
Part 1: √250 would be simplified to 5√10, because you need to find two factors that equal 250. 25 multiplied by 10 are two factors that you can utilize. Because 25 is a perfect square, it could be reduced to 5. Because 10 isn't a perfect square, you leave it as a radical.
Part 2: √250 is an irrational number because it's a non-terminating decimal and you cannot convert it into a fraction, so it wouldn't be rational.
Level 3
Part 1: √150x^5 would be simplified to 5x^2√6x. Again, find two factors that equal the product, 150. 25 multiplied by 6 are two factors that are useable. Just like the first question, 25 is a perfect square, so it can be reduced to 5. 6 is not a perfect square, so you would leave as a radical. Now, moving onto x^5. You can factor out x^4, because it's a perfect square. x^4 can become x^2. Move x^2 next to 5 and x would be left in the radical with 6.
Part 2: It's rational because 2√4 is simply just 2 x 2 because √4 is a perfect square. 4+7=11. 11 can be converted into a fraction, so it wouldn't be irrational.
Level 4
Part 1: 13√750x*5 y*8 would be simplified to 65x^2y^4√30x. Find two factors that equal 750, which are 25 and 30. You know the drill, 25 is reduced to 5 and 30 stays as a radical. Multiply 13 and 5 to get 65. Factor out x^4 out of x^5 to get x^2. x^8 is a perfect square that can be reduced to x^4.
Part 2: Two unique expressions are 4√16+3 and 5√8 x 34. √16 is a perfect square, so it can become 4. 4 x 4 is 16 and 16 + 3 = 19. 19 is a rational number. 5√8 is irrational, so right off the bat, you'll know it's an irrational expression.
please i need helpp ion get math at all
Answer:
you have to use the Pythagorean theorem. a^2 + b^2= c^2
72^2 + b^2 = 75^2
5184 + b^2 = 5625 (subtract 5184 from both sides)
b^2= 441 (find the square root of each side)
b= 21

The sum of two numbers is 105. The larger number is 6 less than twice the smaller
number. What are the numbers?
Answer: x=68, y=37
Step-by-step explanation:
The equation for the sum of two numbers is 105 would be x+y=105. You can say the larger number would be x and the smaller would be y. So, x=2y-6. then you plug that into the x in the first equation.
2y-6+y=105
3y-6=105
3y=111
y=37
Then you would plug in the y to one of the equations. I will do the second one but you can do either one.
x=2y-6
x=2*37-6
x=74-6
x=68

Step-by-step explanation:
they are all going down while the others rise
through: (1, 2), slope = 2
Answer:
y=2x+2
Step-by-step explanation:
Answer: y = 2x
Step-by-step explanation:
y=mx+b
m is the slope. so if the slope is 2 we can fill in 2 for m.
y = 2x + b
now we are going to plug in the point they gave us (1, 2) to find b.
1 is the x coordinate of the point and 2 is the y coordinate. so we put 1 in for x and 2 in for y.
2 = 2(1) + b
2 = 2 + b
b = 0
so our equation is y = 2x + 0, or y = 2x

Desmond has already jarred 4 liters of jam and will jar an additional 3 liters of jam every day. Write an equation that shows the relationship between the days d and the jam made j. Write your answer as an equation with j first, followed by an equals sign.
Answer: j = 3d + 4
======================================================
Explanation:
Referring to the answer above, the "+4" at the end represents the amount Desmond already has. He started off with 4 liters.
The 3d represents the 3 liters he gets per day, where d is the number of days.
So we combine the two elements getting 3d+4 representing the number of liters at any given day. That's why the answer is j = 3d+4
If we plug in d = 0, then j = 3d+4 = 3*0+4 = 4 liters is what he starts with.
If we plug in d = 1, then j = 3d+4 = 3*1+4 = 7 liters is what he has the following day. This shows Desmond gained 3 more liters.
If you plug in d = 2, you'll find that 3d+4 becomes 10, showing yet another 3 liters is added on. This process can go on for as long as you want.

Select all of the expressions that are equivalent to 8/5.
A. 5 x 1/8
B. 8 x 1/5
C. 2 x 4/5
D. 4 x 2/5
C. 2 x 6/5
Answer:
B, C, and D
Step-by-step explanation:
A) 5 x 1/8 is 5/1 times 1/8 which is 5/8 (Incorrect)
B) 8 x 1/5 is 8/1 times 1/5 (multiply straight across and you get 8/5 (Correct)
C) 2 x 4/5 (again, it's 2/1 just multiply straight across and you are basically only multiplying the two numerators each time. Because 1 times 5 will always be 5) (Correct)
D) Correct because 4 times 2 is 8 which is over 5, hence, 8/5 (Correct)
E) 2 times 6 is 12 over 5 which is 12/5, not 8/5. (Incorrect)
