-3.1x+7 -7.4x =1.5 x-6 (x-3/2)

Mathematics

Answer:

x = -113/61, or x = -1.852

Step-by-step explanation:

To solve this equation, remove the decimal fractions by multiplying all terms by 10; the result is:

-31x + 70 - 74x = 15x - 6x + 9.

Then -104x + 70 = 9x + 9, or

         -113x = -61.

Finally, x = -113/61, or x = -1.852

Help me please, what are the like terms?
andriy [413]

Step-by-step explanation:

Like terms are are terms whose variables (and their exponents such as the 2 in x 2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.

So like in your picture x and x would be like terms... your picture helps as well to identify your like terms because your like terms have the same background color to there particular rectangle.

A is (-2,1)
valkas [14]

1) in order to solve this problem you must to obtain The value of K,  for it you know by definition  that the  horizontal slope  of the side BC  is zero ,

then m = Y2-Y/X2-X1,   0 = 5-K/4-6⇒0 = 5-K⇒K = 5

known this value for K   you ca find the equation of thE line that pass through  A and C

2) Following the same procedure in first place you calculate the slope with the points A(-2,1) Y C ( 4,5)

m= 5-1/4-(-2) = 2

now with any point  A  or C and the slope you obtain the line

A(-2,1)

y-y1 = m (x-x1) ,   Y-1= 2(X-(-2)⇒Y-1= 2X+4⇒Y=2X+4-1⇒Y =2X+3
