Answer:

f(x) = 5x + 350

Step-by-step explanation:

Create 2 points using the information given, where x is the number of pounds of coffee and y is the cost.

The 2 points are (100, 850) and (500, 2850)

Then, use rise over run to find the slope:

(y2 - y1) / (x2 - x1)

(2850 - 850) / (500 - 100)

2000 / 400

= 5

Then, plug in the slope and a point into y = mx + b to find b:

y = mx + b

850 = 5(100) + b

850 = 500 + b

350 = b

Plug in the slope and y intercept into y = mx + b to get the equation:

y = 5x + 350

Put it into function form:

f(x) = 5x + 350 is the cost function

HELP PLEASE FIND X AND SHOW YOUR WORK
PtichkaEL [24]

Answer:

34

Step-by-step explanation:

Straight lines are 180 degrees, so the angle inside of the triangle next to the 127, is 53 degrees. (180-127= 53)

So to find "x", we need to figure out what the full number is.

59+53 = 112.

180-112= 68.

Now that we have the degree of the full angle, we can make an equation to find x.

x*2 = 68

(Divide 2 from both sides to isolate the variable)

x = 34  

I hope this helped!

Sin x = cos 53∘ What is the value of x?
love history [14]
Try this solution:
according to the rule sin(90-y)=cos(y), it is possible to re-write the given equation:
sin(90-y)=cos53°, where 90-y=x.
Then substituting the value y=53° into the equation 90-y=x, it is possible to find the 'x': 90-53=37°.

answer: 37°
