Answer:

Step-by-step explanation:
Let's bring the line in the classical
form

At this point we have the two values
for the slope and
for the intercept
Answer:
A
Step-by-step explanation:
We take a look at this expression:
and notice that both terms are square numbers.
and
.
There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares
, it can always be factored into
.
Here, we can apply that. In this case, a = 7x and b = 3. So:

Thus, the answer is A.

Answer:
D
Step-by-step explanation:
40x + 80 > 200
40x (+ 80 - 80) > 200 - 80
40x > 120
40x/40 > 120/40
x > 3
The line needed to have an open circle (x is not greater than or equal to) and it needed to go towards the right on the number line.
Answer:
The new rate would be 3.75%
Step-by-step explanation:
Purchasing a point simply implies negotiating for a lower rate of interest, which involves paying 1% of the loan in lieu of 1% interest reduction.
A point implies a reduction in interest rate by 0.25% while 3 points would reduce the interest rate by 0.75%(0.25%*3)
New interest rate=4.5%-0.75%=3.75%
