what is the equation of a line perpendicular to 2x-3y=6 and passes through the point (6,-1) ?
Answer:
y=-3/2x+8
Step-by-step explanation:
Alright so first we need to convert this equation to Y=mx+b form.
We get y=2/3x-2
In order for it to be perpendicular, we must use -3/2 as the slope.
y=-3/2x+b
Next we need to find the y-intercept of this
Plug in 6 for x and -1 for y and solve for b
b=8

Suzy has a collection of quarters and dimes. Together she has 34 coins worth $6.40. How many quarters and how many dimes does Suzy have?
Please show your work :)
Answer:
Quarters = 20
Dimes = 14
Step-by-step explanation:
Dime = x = 10 cent = $0.1
Quarter = y = 25 cent = $0.25
x + y = 34 - - - (1)
0.1x + 0.25y = 6.40 - - - - (2)
From (1)
x = 34 - y
0.1(34 - y) + 0.25y = 6.40
3.4 - 0.1y + 0.25y = 6.40
3.4 + 0.15y = 6.40
0.15y = 6.40 - 3.40
0.15y = 3
y = 3 / 0.15
y = 20
x = 34 - y
x = 34 - 20
x = 14
Quarters = 20
Dimes = 14

Answer:
We have the answer as:
P'(0, 13), O'(-9, 13), R'(-3, 16)
Step-by-step explanation:
Here, we want to find the coordinates of the image after applying the transformation rule to the pre-image
what the transformation rule is saying is that we subtract 3 from the x-coordinate and add 7 to the y-coordinate
mathematically, we have these as follows;
P’ = (3-3, 6 + 7) = (0,13)
Q’ = (-6-3, 6 + 7) = (-9,13)
R’ ( 0-3, 9 + 7) = (-3, 16)

How are the functions
f(x) = 16* and
19(x) = 161/2
related?
Answer:
F(x) = 16^x = 8^2x
g(x) = 16^1/2x = 8^x
So you can see the relationship. They are all of the type a^bx form, with same base of a, f(x) will have larger increasing rate.

Solve the system of linear equations. Y=-1/6x+5 and x+6y=30 Can you explain the steps?
Answer:
Infinitely many solutions
Step-by-step explanation:
y = -1/6x + 5
x + 6y = 30
We can solve this system by using substitution or elimination. Since we are given an isolated y-value, I'll be using the substitution method.
Substitute y = -1/6x + 5 into the second equation for y.
x + 6(-1/6x + 5) = 30Distribute 6 inside the parentheses.
x - x + 30 = 30Combine like terms.
30 = 30Since this is a true statement, we can conclude that this system has a solution of all real numbers, or infinitely many solutions.
We can also see that these equations are indeed equivalent by multiplying the top equation by 6.
6 * (y = -1/6x + 5) → 6y = -x + 30
Adding x to both sides and rearranging terms gives us x + 6y = 30, which is the same as the second equation.
What is the solution to the
y = 4x – 10

Challenge The numbers of home runs a baseball player hits during spring training and during the regular season for four years are shown. Decide if the relationship between home runs hit in spring training and during the regular season is proportional. If the table represents a proportional relationship, find how many home runs are hit during the regular season if the player hit 3 during spring training
Answer:
12
Step-by-step explanation:
Key word: Most likely
First try to find the constant of proportionality
8/2= 4
4/4= 1
20/5=4
24/6=4
Since it says most likely we would say the constant of proportionality is 4.
Since they are asking for 3 homes runs we will do 3 times 4
[tex]3[/tex]×[tex]4=12[/tex]
The player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.
What is constant of proportionality?The constant of proportionality is the ratio between two directly proportional quantities.
Two quantities are directly proportional when they increase and decrease at the same rate.
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Finding the constant of proportionality :-
8/2= 4
4/16= 4
20/5=4
24/6=4
Since, the constant of proportionality is 4.
And, they are asking for 3 homes runs we will do 3 times 4
Therefore, 3 x 4 = 12
Hence, the player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.

Answer: Kiran is correct
Step-by-step explanation: kiran would be correct because if they were to double the length of the rectangle then the corner to corner length would also double. Sure mai is right when she says that the diagonal length is longer then to two side lengths but that doesn't change the fact that it would only double and nothing more.
8/11 x (5/9 - 1/6) ÷ 1 5/9
Answer:
28/165
Step-by-step explanation:
You always use the order of operations, and the order of operations says to solve parentheses first, so you would solve 5/9 - 1/6, and get 7/18.
You would do exponents next, if there were any, but there is not, so you move on to the next operation(s).
The next operations are multiplication and division. From left to right, multiplication is first, so you solve 8/11 x 7/18 and get 28/99. Then, there is a division problem to solve. The problem is 28/99 ÷ 15/9. If you solve that correctly, you will get the answer 28/165.
The next step would be to simplify 28/165, but it cannot be simplified, so you are left with the answer 28/165.
