Answer:
x = -48.
Step-by-step explanation:
40 + 4x = 3x - 8
4x - 3x = - 8 - 40
x = -48.
Answer: 
Step-by-step explanation:
For this exercise you can use the following formula for calculate the slope:

In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:

Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:

Finally, evaluating, you get that the slope of this line is the following:

Answer:
134/300 or 67/150
Step-by-step explanation:
the LCM of 15 and 100 is 300. 15 *20 is 300 so we multiply both the numerator and denominator of 1/15 by 20 to get 20/300, with 38/100 we multiply by 3 to get 114/300. Now we add 20/300 and 114/300 to get 134/300 which has a common factor of 2 so we can simply it to 67/150
Answer: -5, -7, and -9
Step-by-step explanation:
checking the pattern they are subtracting by two by the next term, so subtracting 2 from -3 would be -5 and so on.
Those two numbers are 30 and 12.
30+12=42
and
30*12=360
