Answer:

y= -9x+5

Step-by-step explanation:

27x + 3y = 50

3y=-27x+50

y=-9x+16 $\frac{2}{3}$

We know that theslope is -9 so, use the equation y-y1=m(x-x1)

y-11=-9(x-(-2/3))

y-11= -9x-6 (bc -18/3 is -6)

y= -9x+5

Answer:

y=-9x-17

Step-by-step explanation:

27x+3y=50

3y=-27x+50

y=-9x+50/3

m=-9

y+11=-9(x+2/3)

y+11=-9x-6

y=-9x-17

If f(x)=x-1/x g(x)=x-1 and h(x)=x+1 what is (g•h•f)(x)

eimsori [14]

Answer:

( f o f )(x) = f ( f (x))

= f (2x + 3)

= 2( ) + 3 ... setting up to insert the input

= 2(2x + 3) + 3

= 4x + 6 + 3

= 4x + 9Step-by-step

If p varies directly with q, and p = 10 when q = 5, what is the value of p when q = 20

Inessa [10]

The value of p would be 40. This is because the ratio of p:q = 10:5. this could be simplify into p:q = 2:1. Applying the ratio p:20 = 2:1, P=40.

Tysm for the help! <3

Blizzard [7]

By using the given graph:

When x = -2, the value of the function is f(-2) = 1
When x = -0.5, the value of the function is f(-0.5) = 0.75
When x = 0, the value of the function is f(0) = 1.25
When x = 2.5, the value of the function is f(2.5) = 3
When x = 6, the value of the function is f(6) = 0

<h3></h3><h3>How to use the graph to find the values of the function?</h3>

Suppose that we want to find the value of the graphed function when x = a.

Then we first need to identify x = a in the horizontal axis.
Then we move upwards (or downwards) until we meet the curve of the function.
Now you can move horizontally towards the vertical axis, where you can read the y-value associated to the x-value.

Now we can do these steps for each of the wanted values.

When x = -2, the value of the function is f(-2) = 1
When x = -0.5, the value of the function is f(-0.5) = 0.75
When x = 0, the value of the function is f(0) = 1.25
When x = 2.5, the value of the function is f(2.5) = 3
When x = 6, the value of the function is f(6) = 0

John typed a 48 word paragraph in 2/3 minute. What is the typing speed in words per minute

serg [7]

Answer: The answer is: " 72 words per minute. "

___________________________

Step-by-step explanation:

___________________________

This is a "unit rate" problem.

We want to solve for/ find the number of words PER single minute.

___________________________

Given 48 words per (2/3) minute;

How many words per (one) minute?

__________________________

The answer is {48 ÷ (2/3) } words per minute:

Note: dividing by a number is the same as multiplying by the reciprocal (inverse) of that particular number:

Hence:

__________________________

The answer is {48 * (3/2) } words per minute:

__________________________

Write as:

" $\frac{48}{1} *\frac{3}{2}$ " ;

__________________________

The "48" can be changed to "24" ; and the "2" can be changed to "1" ;

→ {Since: "48 ÷ 2 = 24 "} ;

___________________________

And we have:

___________________________

" $\frac{24}{1} *\frac{3}{1} = 24 * 3 = 72$ " ;

___________________________

The answer is: " 72 words per minute ."

___________________________

Hope this is helpful to you!
