X-intercept and y-intercept of 9.3x+4.2y+3.9=0

Mathematics

Answer:

y intercept = -0.93

x intercept = -0.42

Step-by-step explanation:

To get x intercept, substitute y for 0 and solve for x.

To get y intercept, substitute x for 0 and solve for y.

X intercept:

9.3x + 4.2y + 3.9 = 0

9.3x + 4.2(0) + 3.9 = 0

9.3x + 3.9 = 0

Subtract 3.9 to get it on the other side

9.3x + 3.9 - 3.9 = 0 - 3.9

9.3x = -3.9

Divide 9.3 to get x by itself

(9.3x) / (9.3) = (-3.9) / (3.9)

x = -0.419355

Since there are some extra numbers, I will round it to the nearest hundredth to make it easier

-0.419355 = -0.42

Y intercept:

9.3x + 4.2y + 3.9 = 0

9.3(0) + 4.2y + 3.9 = 0

4.2y + 3.9 = 0

Subtract 3.9 to get it on the other side

4.2y + 3.9 - 3.9 = 0 - 3.9

4.2y = -3.9

Divide 4.2 to get y by itself

(4.2x) / (4.2) = (-3.9) / (4.2)

x = -0.928571

Round answer to nearest hundredths

-0.928571 = -0.93

Notes:

If your answer is an extended decimal number, round it to the nearest hundredths to make it easier

The Pool Fun Company has learned that, by pricing a newly released Fun Noodle at $3, sales will reach 6000 Fun Noodles per day d
Salsk061 [2.6K]
PART A:
 The generic equation of the line is:
 y-yo = m (x-xo)
 First we look for the slope of the line:
 m = (y2-y1) / (x2-x1)
 m = ((5000) - (6000)) / (4-3)
 m = -1000
 Then, we substitute any point in the generic equation:
 (xo, yo) = (4, 5000)
 Substituting:
 y-5000 = (- 1000) (x-4)
 Rewriting:
 y = -1000x + 4000 + 5000
 y = -1000x + 9000
 The equation is:
 y = -1000x + 9000

 PART B: 
 For the price of 3.50 we have:
 y = -1000 * (3.5) +9000
 y = 5500

Please answer the question correctly and with a good explanation. Please and thank you
Angelina_Jolie [31]

Answer:

48

Step-by-step explanation:

To calculate the area of a composite shape you must divide the shape into rectangles, triangles, or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes.

I split it into a square and a trapezoid

The area of the square is 6x5 = 30

The area of the trapezoid is

A=a+b

2h=3+6

2·4=18

So add the area together

30+18= 48
