Answer:  The required solution is x = -0.69.

Step-by-step explanation:  We are given to solve the following equation for the value of x :

78(-32-48x)+36=23(-33x-18)-10x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the value of x, we must bring all the terms involving x on one side of the equality.

The solution of equation (i) is as follows:

78(-32-48x)+36=23(-33x-18)-10x\\\\\Rightarrow -2496-3744x+36=-759x-414-10x\\\\\Rightarrow -3744x-2460=-769x-414\\\\\Rightarrow -3744x+769x=-414+2460\\\\\Rightarrow -2975x=2046\\\\\Rightarrow x=-\dfrac{2046}{2975}\\\\\Rightarrow x=-0.69.

Thus, the required solution is x = -0.69.

LaTonda rolls two number cubes that are each numbered 1 through 6. What is the probability that the sum of the numbers on the to
ZanzabumX [31]

Answer:

1/4

Step-by-step explanation:

The maximum sum of the two cubes is 6 + 6 = 12

The multiples of 4 until 12 are: 4, 8 and 12.

each cube has 6 possible values, so two cubes have a total of 6 * 6 = 36 possible results

We can have a sum of 4 with the pairs (1,3), (2,2), (3,1).

We can have a sum of 8 with the pairs (2,6), (3,5), (4,4), (5,3), (6,2)

We can have a sum of 12 with the pair (6,6)

So we have a total of 9 pairs that satisfy our condition over a total of 36 possibilities, so the probability is 9 / 36 = 1/4

Calculate the slope of a line that passes through the points (-4,7) and (-1,3)
zmey [24]

Answer:

The answer is

-  \frac{4}{3}  \\

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,7) and (-1,3)

We have

m =  \frac{3 - 7}{ - 1 -  - 4}  =  \frac{ - 4}{ - 1 + 4}  =   -  \frac{4}{3}  \\

We have the final answer as

-  \frac{4}{3}  \\

Hope this helps you
