Answer:
A, a centimeter is smaller so therefore it is more accurate.
a. If a point is in the first quadrant, then its coordinates are positive
b. If the coordinates of a point are positive, then the point is in the first quadrant
c. If the coordinates of a point are not positive, then then the point is not in the first quadrant
d. If a point is not in the first quadrant, then the coordinates of the point are not positive.
Answer:
b. If the coordinates of a point are positive, then the point is in the first quadrant
Step-by-step explanation:
3n = 30
5n + 8n = 30
5n = 8n + 30
Answer: the correct option is
(C)
Step-by-step explanation: Given that five times a number is the same as 30 more than 8 times the number.
We are to find the number.
Also, if the number is denoted by n, then we are to select the equation that could be used to solve for the number.
Since n is the given number, so five times the number is written as
Also, 30 more than eight times the number is written as
Since both the expressions are same, so we get
Thus, the required number is -10 and the the equation that is used to solve for the number is
Option (C) is CORRECT.
Answer:
Step-by-step explanation:
You have a vertex coordinate and 2 points. In order to write the equation for that parabola, you only need the vertex and one point. We will fill in the following work form of the parabola:
, where h and k are from the vertex and x and y are from the point. Filling in:
and
and
and
9 = 9a s0
a = 1.
Now we can write the equation, filling in a, the only unknown we had, which we now know is 1:
Answer:
y = 1(x + -5)2 + 3
