Answer:
-1/4
Step-by-step explanation:
Perpendicular lines have slopes that multiply to -1
m * 4 = -1
Divide by 4
m = -1/4
The slope of a line that is perpendicular to a line that has a slope of 4 is -1/4
Answer:
6
Step-by-step explanation:
Answer:
-24
Step-by-step explanation:
Easy way: 42 - 18 = 24, then translate it to negative 24 because your numbers are negative.
A little bit harder way: -42 + (-18) or -42 + 18 = -24
Answer:
goes into the box
Step-by-step explanation:
Let the number be 
, then
We now use the following property of exponents to simplify the left hand side of the equation.
This implies that;
Since the bases are the same, we equate the exponents to get;
We now multiply both sides by 3 to get;
Therefore the number that goes into the box is
A. The data in the table represent a function. y=x/2. This is seen as for every value of x in the table, y=x/2(half of it). You can show this further by trying this fact on each value.
B. For the original function, when x =8, y=x/2=4
For the function given in this part, when x=8, y=3(8)-10
y=24-10 y=14
This means the relation given in this part has a greater value when x=8
C. When x=80, f(x)=3(80)-10
=240-10
=230
