y + 11 = –2(x + 1.5)
y=mx+b
multiply the bracket by -2
(-2)(x)=-2x
(-2)(1.5)=-3
y+11=-2x-3
move +11 to the other side
sign changes from +11 to -11
y+11-11=-2x-3-11
y=-2x-14
m is also the slope
b= y-intercept
Answer:
y-intercept=-14
Answer:
The number of packages of chocolate chip cookies sold was 44 and the number of packages of sugar cookies sold 161
Step-by-step explanation:
Let
x ----> the number of packages of chocolate chip cookies sold
y ----> the number of packages of sugar cookies sold
we know that
-----> equation A
-----> equation B
Solve the system of equations by graphing
The solution is the intersection point both graphs
using a graphing tool
The solution is the point (44,161)
see the attached figure
therefore
The number of packages of chocolate chip cookies sold was 44 and the number of packages of sugar cookies sold 161
Answer:
A culture started with 5000 bacteria. after 4 hours, it grew to 6000.
=> Increasing rate = difference/time = (6000 - 5000)/4 = 250 bacteria/hour
=> The number of bacteria after 17 hours:
N = 5000 + 250 x 17 = 9250 bacteria
Hope this helps!
