Answer:

x=-1

x=-2

Step-by-step explanation:

1. To solve this problem you can graph the quadratic function, as you can see in the graph attached.

2. You can estimate the solution of the quadratic function by observing two points where the parabola intersect the x-axis.

3. Keeping the the information above on mind, you can estimate that the solution is:

x=-1

x=-2

NOTE:

You can also find two numbers whose sum is 3 and whose product is 2. Then:

(x+2)(x+1)=0\\x=-2\\x=-1

Help pleaseeeeeeeeeeeeee!!!!!!!!!!!!!!!! T^T

1 + (-5/8) = 3/8

Explanation: If the coffee wasn’t drank it would’ve been at fraction 1 (or 100%)

Since he drank 5/8 of it. The coffee left is now 1-(5/8)

But since the question has asked to give the equation in addition format. Put a plus sign in between the two.

Therefore,
1 + (-5/8)

Solve it,
= 1-(5/8)
= (8-5)/8
= 3/8

Hence the equation is:

1 + (-5/8) = 3/8.

A town has a population of 8000 and grows at 3% every year. To the nearest tenth of a year, how long will it be until the popula
Alexxx [7]

Answer:

It will take approximately 34 years

Step-by-step explanation:

If a town population is 8000 and grows 3% annually.

How long will it take to reach 16300

growth is 16300 - 8000 = 8300

using simple interest formula

SI = (P × r × t)/100

8300 = (8000 × 3 × t)100

8300= (80 × 3)t

8300 = 240t

t = 8300/240

t ≈ 34 years to the nearest tenth
