Answer:
Step-by-step explanation:
4(x-3)2-5 = 139
(4x-12)-5=139
-20x + 60 = 139
-20x +60 - (60) = 139- 60
-20x = 79 divide both sides by -20
x = -3.95
Answer:
-1/8
Step-by-step explanation:
Perpendicular slopes are negative reciprocals
The slope of y=8x+5 is 8, because it is in slope intercept form: y=mx+b form, where m is the slope.
Negative:
8/1--> -8/1
Reciprocal:
Flip the numerator and denominator
-8/1--> -1/8
So, the perpendicular slope of 8 is -1/8
Answer: 14x^7
You add the coefficients (numbers to the left of the variable terms) to get 6+8 = 14 which is the coefficient of the final answer. The x^7 stays the same. It's like saying "we have 6 apples added to 8 apples, so there are 14 apples overall". Replace "apples" with "x^7" and it's the same idea.
They equal 5*5=25 and 35*35=1225
We can use substitution to solve this equation in here y=6 and x=0 .
Hope this help you !
