Answer:
.
Step-by-step explanation:
A line that goes through 
and 
where 
would have a slope of 
.
The slope of the line that goes through 
and 
would thus be:
.
Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is 
.
Thus, if 
and 
denote the slope of the first and second lines in this question, 
since the two lines are perpendicular to one another. Since 
, the slope of the first line would be:
.
Given that the first line goes through the point 
, the point-slope equation of that line would be:
.
.
Substitute in 
to find the 
-coordinate of the point in question:
.
Answer:
a is 625 work: 5*5*5*5=625
b is 16807 work: 7*7*7*7*7=16807
c is 0.0625 work: .5*.5*.5*.5
d is 2744 work: 14*14*14
Step-by-step explanation:
Since they are starting with 270, the y intercept is going to be 270, now since they are losing 15 food everyday, the slope is going to be -15 so the final equation is y=-15x+270
Answer:
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable.
Step-by-step explanation:
Answer:
x=13 and y =6
Step-by-step explanation:
y=x-7
y=6
Substitute y=6 into the first equation
6 = x-7
Add 7 to each side
6+7= x-7+7
13 = x
x=13 and y =6
