If y = 3 when X = -9 find X when y =5

Answers

Answer 1
Answer: We don't have enough information to answer that question.

You haven't told us anything about how 'y' depends on 'x',
or how 'y' reacts to a change in 'x'.

If we think about it in terms of a graph, you've given us one point
on the graph . . . the point  (-9, 3).  In order to answer the question,
we need to know something about the line that goes through the
point.  But you haven't told us anything about that, and there are
an infinite number of different lines that can go through one point.

ursula earns $9 per hour. to write an expression that tells how much money ursula earns for h hours, josh wrote 9\h. sarah wrote 9h. whose expression is correct and why

Answers

The important information's already given in the question can be used to find the correct answer.
In 1 hour Ursula earns = 9 dollars
So
In h hours Ursula earns = (9/1) * h dollars
                                       = 9 * h hours
                                       = 9h hours
So we have found from the above discussion that Sarah wrote the correct answer and it was 9h.I hope you are satisfi3ed with the answer and theexplanation that I have provided. You can use this procedure for solvingsimilar problems.




Sarah is correct because if Ursula is earning $9 per hour then every hour you can add 9. Lets say h=2 then you would multiply 9*2 to get how much she spent. Josh is incorrect because dividing would subtract the amount of money every our.

There are 12 students in a classroom, including the triplets joey, chloe, and zoe. If 3 of the 12 are randomly selcted to give speeches, what is the probability that joey with be first, chloe will be second, and zoe will be third?A: 1/1320 B: 1/4 C: 1/48 D: 1/220

Answers


The probability of choosing Joey first is  1/12 .

If that happens, the probability of choosing Chloe next is  1/11 .

Then, the probability of choosing Zoe after that is  1/10 .

The probability of all these things happening is

          (1/12) x (1/11) x (1/10) 

       =  1/1320 = 0.00076 = 0.076 percent 

Given B is between A and C, find the value of x if AB = 22, BC = 16x, and AC = 182.

Answers

Answer:

10

Step-by-step explanation:

Since we know that B is between A and C, it doesn't matter where B is, but, we are sure that AB plus BC equals AC. In an equation:

AB+BC=AC

We know that AB is 22, BC is 16x, and AC is 182. Substitute:

22+16x=182

Now, find the value of x. Subtract 22 from both sides:

16x=160

Divide both sides by 16:

x=10

So, the value of x is 10.

And we're done!

Answer:

x=10

Step-by-step explanation:

Start with:

AB+BC=AC

Substitute in your values.

22+16x=182

Subtract 22 from both sides of the equation.

16x=182-22

Combine like terms.

16x=160

Divide by the coefficient of x, which in this case is 16.

x=10

what is the solution to the system of equations? y =1/3 x – 10 2x y = 4 (–8, 6) (–6, 16) (6, –8) (16, –6)

Answers

Answer:

Option C is correct.

Solution to the given system of equation is (6 , -8)

Step-by-step explanation:

Given the system of equation:

y= (1)/(3) x-10             ......[1]

2x+y =4                           .....[2]

Substitute the equation [1] in [2] we get;

2x +(1)/(3)x -10 =4

Combine like terms;

(7)/(3)x -10 =4

Add 10 to both side of an equation:

(7)/(3)x -10 +10=4+10

Simplify:

(7)/(3)x =14

Divide both sides by  (3)/(7) we get;

(3)/(7) * (7)/(3)x = 14 * (3)/(7)

Simplify:

x = 6

Substitute the value of x =6 in equation [1] we get;

y= (1)/(3)(6)-10

or

y= 2-10  

Simplify:

y = - 8

therefore, the solution to the given system of equation is; (6 , -8)

You can also see in the graph as shown below:

y = 1/3 x - 10
2x + y = 4
2x + 1/3 x - 10 = 4
7/3 x = 14
x = 6
y = 1/3(6) - 10 = 2 - 10 = -8
Therefore solution is (6, -8)
