Answer:
The slope is zero. Since both coordinates have the y-value of -1, they are on the same line on the graph and form a horizontal line with a slope of zero. (a straight horizontal line)
Step-by-step explanation:
use the formula
(y2-y1)/(x2-x1)
to calculate the slope using 2 points
so where (x1,y1) (x2,y2) can be subsituted
so putting it in the formula ...
(-1-(-1))/(7-10)=
0/-3=0
Answer:
7. y
=
−
1
/2
x + 4
8. y= (0,4)
Step-by-step explanation:
7. the slope is -1/2 and the y intercept is 4
8. so basically, the y intercept is when y is zero, which makes this one (0,4)
HOPE THIS HELPS HAVE A GREAT DAY!!! IM procrastinating chem doing this lolz
Answer:
The population will reach 20,400 after 6 years.
Step-by-step explanation:
Exponential function:
y(t)= Population after t years
= initial population
r= rate of grow
t= time.
A town has a population of 17,000 and grows at a rate 3% every year.
y(t)= 20,400, = 17,000, r=3%=0.03, t=?
Taking ln function both sides
⇒ t = 6 year.
The population will reach 20,400 after 6 years.

Answer:
(3,2)
Step-by-step explanation:
2x+5y=16
3x-5y=-1
Subtract 2x from the first equation
5y=16-2x
Substitute the given value of 5y into the equation
3x-(5y)=16
3x-(16-2x)=-1
Solve for x
3x-(16-2x)=-1
3x-16+2x=-1
5x-16=-1
5x=15
x=3
Substitute the given value of x into the equation
3x-5y=-1
3*3-5y=-1
Solve
3*3-5y=-1
9-5y=-1
-5y=-10
y=2
