If y is directly proportional to x and y = 11 when x = 6 , what is the value of y when x = 9

1 answer:

3 0

Since we are given that y is directly proportional to x and that when y = 11, x equals 6, we can set up a proportion. Before doing that however, we need to note that the question is asking for the value of y when x = 9. Here is the equation:
$\frac{11}{6} = \frac{y}{9}$
Now, just cross multiply and solve for y to get a value of 16.5. Therefore, the value of y when x = 9 is 16.5. Hope this helped and have a phenomenal day!

The daily profit, P, of a local bakery can be calculated using the formula P=m-(250+4h) when employees work a total of h hours a

qwelly [4]

Answer:

$m=665+4h$

Step-by-step explanation:

Profits of the local bakery is given by

$P=m-(250+4h)$

where

m = Amount of money to be received

P = Profit

h = Number of hours worked

Now P = $415

So,

$P+(250+4h)=m\\\Rightarrow m=P+250+4h\\\Rightarrow m=415+250+4h\\\Rightarrow m=665+4h$

The equation to calculate the amount of money, m, the bakery should receive if the desired profit is $415 is $m=665+4h$ .

Given the system of equations presented here:

Vinvika [58]

The action that creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated is " Multiply the second equation by -4 to get -16x - 4y = -80 " ⇒ answer a

Step-by-step explanation:

To solve a system of equation using the elimination method

Make the coefficient of one variable in the two equations have same values and different sign
Add the two equation to eliminate this variable
Solve the resulting equation to find the other variable
Substitute the value of the other variable in one of the two equations to find the value of the eliminating variable

The system of equation is :

2x + 4y = 14 ⇒ 1st equation

4x + y = 20 ⇒ 2nd equation

You can multiply first equation by -2 to get

-4x - 8y = -28 ⇒ 3rd equation

When you add the second and the third equations x will eliminated

<em>OR</em>

You can multiply second equation by -4 to get

-16x - 4y = -80 ⇒ 3rd equation

When you add the first and the third equations y will eliminated

The action that creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated is " Multiply the second equation by -4 to get -16x - 4y = -80 "

1. A line that passes through the point (-1, 3) has a slope of 2. Find another point on the line.

Stella [2.4K]

Answer:

option Bis correct answer.

Step-by-step explanation:

given, a line passes through the point (_1,3)and has slope 2.let another point be x2 and y2.

by the slope formula,

slope (m)=

$y2 - y1 \div x2 - x1$

or , 2=y2_3/x2_(_1)

or, equating with slope we get,

2=y2_3

or, y2=5

again, 2=x2+1

therefore, x2=1

so the points are (1,5)........ans....
