Answer:
The number of girls is at most 9 girls
y ≤ 9
Step-by-step explanation:
The chess clubcab have at most 36 members.
At most means : Less than or equal to 36 members and it is represented by the inequality = ≤
The are 3 times as many boys as girls in the chess club.
Boys = x
Girls = y
Hence,
x = 3y
Which inequality could be used to determine the possible number of girls, x, in the chess club?
Therefore,
x + y≤ 36
3y + y ≤ 36
4y ≤ 36
y ≤ 36/4
y ≤ 9
Girls = y
The number of girls is at most 9 girls
Answer:
55 gallons, the initial quantity of water in the tank
Step-by-step explanation:
Y is defined as the amount of water in the tank. When X (the number of minutes spent draining) is zero, no water has left the tank. So, the Y-intercept is the initial amount of water in the tank, 55 gallons.
ANSWER
D) (a + 1, b + m)
EXPLANATION
The given line passes through (a,b) and has slope m.
The equation is:

When x=a+1, we obtain

This


Therefore,(a + 1, b + m) must also lie on this line.
The correct answer is D.
The distance between the points (d) is found using the Pythagorean theorem.
Imagine the two points as defining the hypotenuse of a right triangle. The lengths of the legs of the triangle are the horizontal distance between the points and the vertical distance between the points. The the theorem tells us
d² = 4² + 7²
d² = 16 + 49
d² = 65
d = √65 ≈ 8.1
The distance between the points is
C 8.1_____
You know that the distance must be longer than the longest leg (7) and must be shorter than the sum of the two legs (4+7=11). The only answer choice between 7 and 11 is 8.1.
