Solve0.9(7x + 14) = 1.5 - (x + 2)

Mathematics
1 answer:
Triss [41]3 years ago
7 0

\\ \sf\longmapsto 0.9(7x+14)=1.5-(x+2)

\\ \sf\longmapsto 6.3x+12.6=1.5-x-2

\\ \sf\longmapsto 63x+12.6=-x-0.5

\\ \sf\longmapsto 63x+x=-0.5-12.6

\\ \sf\longmapsto 64x=-13.1

\\ \sf\longmapsto x=\dfrac{-13.1}{64}

\\ \sf\longmapsto x=0.2

vagabundo [1.1K]

Answer:

Step-by-step explanation:

Put the ordered pairs into the slope formula x=y2-y1/x2-x1 then you will get your slope of the line. once you have your slope pick an ordered pair and put it in point slope y-y1=m(x-x1) distribute and you will get your answer.

1. How many solitions does this equation have -4(5-3x)=12x+20
Rom4ik [11]

Answer:

1. no solutions

2. one solution

Step-by-step explanation:

1. -4(5-3x)=12x+20

-20+12x=12x+20

-40+12x=12x

-40=0?????

So no solutions.

2. 3x+7(x+1)=2(6x+5)+2

3x+7x+7=12x+10+2

10x+7=12x+12

-2x+7=12

-2x=5

x=-5/2

So one solution.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (8,-5)(8,−5) and (4,3)(4,3).
Marysya12 [62]

Answer:

Correct answer\\y=\frac{1}{2} x-4

Step-by-step explanation:

y-\frac{-5+3}{2} =\frac{-1}{\frac{3-(-5)}{4-8} } (x-\frac{4+8}{2} )\\y+1=\frac{1}{2} (x-6)\\y=\frac{1}{2} x-4

What is the decay factor of the exponential function<br> represented by the table?
bulgar [2K]

Given:

The table of values of an exponential function.

To find:

The decay factor of the exponential function.

Solution:

The general form of an exponential function is:

y=ab^x              ...(i)

Where, a is the initial value and 0 is the decay factor and b>1 is the growth factor.

The exponential function passes through the point (0,6). Substituting x=0,y=6 in (i), we get

6=ab^0

6=a(1)

6=a

The exponential function passes through the point (1,2). Substituting x=1,y=2,a=6 in (i), we get

2=6(b)^1

2=6b

\dfrac{2}{6}=b

\dfrac{1}{3}=b

Here, b=\dfrac{1}{3} lies between 0 and 1. Therefore, the decay factor of the given exponential function is \dfrac{1}{3}.

Hence, the correct option is A.
