Answer:
Step-by-step explanation:
if you know 50*4=200, you must also know that 50*10=500 and that 4*100=400 so 500*400= 50*10*4*100
multiplication is comutative so
50*4*10*100=200*1,000= 200, 000
SOLUTIONS
Given: Assume y is the population
The town grow at the rate of 30 people per year.
(A) The population predicted to be in 2030 will be
(B) so when y = 15000, find t
Answer:
B, 20mph
Step-by-step explanation:
540 miles in 27 hours is 540/27 = 20 miles in 1 hour. This is 20 mph
STEP-BY-STEP SOLUTION:
( x + 4 )^2 + y^2 = 22
x^2 + 2 × x × 4 + 4^2 + y^2 = 22
x^2 + 8x + 16 + y^2 = 22
y^2 = 22 - x^2 - 8x - 16
y^2 = - x^2 - 8x + 6
FINAL ANSWER:
Therefore, the answer is:
D. y^2 = - x^2 - 8x + 6
