8/10 is equivalent to 4/5 because if you multiply the numerator and denominator by 2 you will get 8/10. 1/2 is not equivalent to 7/12 because if you multiply the numerator and denominator 6 you will get 6/12 and not 7/12. 3/4 is not equivalent to 8/12. 2/3 is equivalent to 4/6. I hope this helped you

A line passes through the points (-6, 4) and (-2, 2). Which is the equation of the line?
jek_recluse [69]

Answer:

Correct answer not shown on the options.

y = -(1/2)+1

Step-by-step explanation:

Let's find an equation in the format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

The slope can be calculated as the Rise/Run of the line between the two given points (-6,4) and (-2,2):

Rise = (2 - 4) = -2

Run = (-2 - (-6)) = 4

Slope = Rise/Run = -2/4 or -(1/2)

In fact, the actual full equation is y= -(1/2)x+1  (See attached graph).

None of the options have a slope of -(1/2).  Either the information on the two points or the options are incorrect.

80 POINTS! WILL GIVE BRAINLY
PSYCHO15rus [73]

Answer:

Step-by-step explanation: No, Gavin is not correct because 284.42 is less than 400 the equation is 200(1+0.09/2)^8 when solved you get 284.42 which is not enough.

Step-by-step explanation:

simplifying this

Ok so do 0.09/2 which is 0.045 then add 1 so you get 200•1.045^8 then you do 1.045^8= 1.422100.... so I did 1.422100•200 to get the final answer of 284.42

Factor this expression. x2 + 9x + 8
TEA [102]
X^2 + 9x + 8 = 0

To find the factors we need to find two number that multiply to equal 8 but add to equal 9.

8 = 1*8        9 = 1+8

(x + 1)*(x + 8) = 0

The expression 12x+15x-11x can be combined because of which property
marshall27 [118]

Answer:

The expression 12x+15x-11x can be combined because of the commutative property of addition.

Step-by-step explanation:

A monomial is a number, a variable or a product of a number and a variable where all exponents are whole numbers. That means that

12x+15x-11x

all are examples of monomials.

The commutative property of addition says that changing the order of addends does not change the sum.

If we add [(a + b)+ c] or [a + (b + c)], the result will be same.

Therefore,

12x + 15x - 11x = (12 + 15 - 11)x\\12x + 15x - 11x  = (27 - 11)x\\12x + 15x - 11x  = 16x

Find an explicit formula for the arithmetic sequence 170,85,0,-85...,<br> d(n)=
irinina [24]

Answer:

d(n) = 85 * ( 3 - n )

Step-by-step explanation:

Let's find the common difference of the terms (if any).

The common difference is = 85 - 170 = 0 - 85 = -85 - 0 = -85

For an arithmatic sequence with first term a, common difference d,

  nth term = a + ( n - 1 ) * d

So, d(n) = 170 + ( n - 1 ) * (-85)

             = 255 - 85n

             = 85 ( 3 - n )

[ If there's any mistake, please inform me ]
