dexar [7]3 years ago
7 0

Answer:

x=13

Step-by-step explanation:

6:(x+2)=2:5

6/x+2=2/5

cross multiply

2(x+2)=6×5

open the bracket

2x+4=30

2x=30-4

2x=26

divide by 2

2x/2=26/2

x=13

60 EXTRA POINTS!!!! I need help with writing an inequality for a graph. It is below. :)
ch4aika [34]

Answer:

The answer to your question is:   y ≥ - x + 6  and   y ≥ x - 4

Step-by-step explanation:

Look of a pairs of points for each graph

Line 1                                                  Line 2

A(0, 6)     B (5, 1)                                 C (7,3)               D(5, 1)

m =  (1- 6) / (5- 0)                               m = (1 - 3) / (5 - 7)  

m = -5/5 = -1                                      m = -2 / -2 = 1

Find  the line equation for each slope   (y - y1) = m (x - x1)

(y - 1) = -1 (x - 5)                                 (y - 1) = 1 (x - 5)

y - 1 = -x + 5                                       y -1 = x - 5

y = -x + 5 + 1                                       y = x - 5 + 1

y = -x + 6                                           y = x - 4

Inequality

y ≥ - x + 6                                          y ≥ x - 4

What is the answer to the problem 2/3x-40=5/6(x+36)
miss Akunina [59]

2/3x-40=5/6(x+36)

multiply each side by 6 to get rid of the fraction

6* 2/3x- 6*40=6*5/6(x+36)

4x -240 = 5(x+36)

distribute

4x-240 = 5x +180

subtract 4x from each side

-240 = x +180

subtract 180 from each side

-420 =x

When a curve and a line meet at a point, are their gradient equal?​
Natali [406]

Check the picture below.

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

well, by the definition of a derivative, the slope at the point is f'(a), and any tangent line going through it will also have the same exact slope, keeping in mind that a straight line has a constant slope.
