Answer:
Connie started with <u>$25</u> in her savings account.
Step-by-step explanation:
The y-intercept is the value of the function at time zero.
At x = 0, which is week zero, when Connie opened the account, the y value is 25. That means she opened the account with $25.
Answer: $25
Answer: B. 4x*2x^2+4x*(-2)+1*4x+1*(-2)
Step-by-step explanation: Hope this help :D
B, because you subtract 9 from both sides(2x-9 leaves 2x by itself then 33-9=24), which leaves you with 2x=24 the you divide everything by 2 which leaves you with x=12
Answer: 14
Step-by-step explanation:
28 times 0.5. First do 28 times 5. Then do 28 times 0. When multiplying with zeros, any number times zero, is zero. Your answer is 14.
Answer:
Step-by-step explanation:
To answer this question, we will work backwards.
We know that a factor is 4+3i. This means that:
Hence, we will eliminate the imaginary and convert this into standard form.
First, distribute the negative:
Add 3i to both sides:
Square both sides:
Expand:
Add 9 to both sides:
Hence, our quadratic equation is:
Notes:
We will get the same equation if we use (4-3i). This is because we square the (3i) regardless of its sign, making it positive.
