Answer:
2.15 * 10^-3
Step-by-step explanation:
Rewrite the given equation in slope intercept form:
5 y = 10 – 2 x
y = - 0.4 x + 2
Since the two lines are parallel, therefore they have
similar slope which is – 0.4, so the equation is:
y = - 0.4 x + b
Given that x = 5, y = -4, find for b:
-4 = - 0.4 (5) + b
b = -2
So the answer is:
y = - 0.4 x – 2
or

Answer:
The total number of students she teaches is 115
Step-by-step explanation:
Here, we want to get the total number of students that Mrs Randolph teaches
To get this, we simply add up the number for the individual sessions
Mathematically, we have this as;
26 + 32 + 27 + 30 = 115 students
8n−7y−12n+5−3y
=8n+−7y+−12n+5+−3y
Combine Like Terms:
=8n+−7y+−12n+5+−3y
=(8n+−12n)+(−7y+−3y)+(5)
=−4n+−10y+5
eight 5 and thirty 2
Step-by-step explanation:
8 times 5 = 40 and then 30 times 2 = 60
40+60= 100
