Answer:
n = 20
Step-by-step explanation:
n/2 - 9 = 1
Add 9 to each side
n/2 -9+9 = 1+9
n/2 = 10
Multiply by 2 on each side
n/2*2 = 10*2
n = 20
Answer:
y=2x-6
Step-by-step explanation:
Parallel functions are functions with the same slopes but are in different positions on the coordinate plane (for this case it means that they have different y- intercepts)
So this means that the function will have a slope of 2
To find the equation we must plug in the value (1, -4) and find the new y-intercept(c)
(-4)= 2(1)+c
-4-2=c
-6=c
This means that the parallel function that goes through the point (1,-4) is
y=2x-6
Part a)
for extraneous solution
<span>
1 ⋅ sqrt(x+2) + 3 = 0</span>
for non extraneous solution
1⋅ sqrt(x+2) + 3 = 6
part b) solve each equation
1⋅sqrt(x+2)+3=0
x+sqrt(x+2)=−3
square both sides
(sqrt(<span>x+2)</span>)^ 2 = (−3)^2
x+2=9
x=9−2
x=7
do you see why its extraneous
Answer:201 students
Step-by-step explanation: Since there are seven kids riding in cars, you would subtract 7 from 1213 to get 1206 students. The six buses means you divide by 6 to get 201 students in each bus.
