Answer:
B
Step-by-step explanation:
Our equation is x² + 7x - 4 = 0. We need to use the quadratic formula, which states that for a quadratic formula of the form ax² + bx + c = 0, then the zeroes/solutions are: or .
Here, a = 1, b = 7, and c = -4. Plug these in:
OR
Thus, the answer is B.
Answer:
the desired equation is y = (-3/2)x + 3
Step-by-step explanation:
Two points through which the graph passes are (0, 3) and (2, 0). (0, 3) is the y-intercept. Thus, the slope-intercept equation y = mx + b becomes
y=mx + 3. Borrowing the coordinates of (2, 0) and substituting them into this last result, we get
0 = m(2) + 3,
which, after having been solved for m, gives us m = -3/2
and so the desired equation is y = (-3/2)x + 3.
The answer is 35 because u need to multiply 7 by 5 because they multiply 9 by 5.

Answer:
An infinite number.
Step-by-step explanation:
There are many, many rational fractions between -6 and -5.
For example, take the numbers - 5 2/7 and - 5 4/7. there is another rational between these - 5 3/7.
Then we have another between - 5 2/7 and - 5 3/7 which is - 5 5/14, - and we could go on doing this all day and never coming to an end!!
