Does the point (2, 9) satisfy the inequality y ≤ 3 x + 1 ?

Mathematics
1 answer:
Naily [24]3 years ago
7 0

A point is written using the form (X,Y), so the first number is the X and the second number is the Y.


Replace x and Y in the given equation with the given point:


y ≤ 3x+1

9 ≤ 3(2) +1

9 ≤ 6 +1

9 ≤ 7


9 is not less than or equal to 7, so the point (2,9) does not satisfy the inequality.

3x-10x+18=4
-7x=4-18
-7x=-14
x=2

5(2)+y=9
10+y=9
y=9-10
y=-1

The answer is (2,-1) :)

Which quadratic function has a leading coefficient of 2 and a constant term of –3?
Romashka [77]
The answer is <span>f(x) = 2x2 + 3x – 3
</span>
f(x) = ax² + bx + c
a - the leading coefficient
c - the constant term

<u>We are looking for a = 2, c = -3</u>

Through the process of elimination:
The first (f(x) = 2x3 – 3) and the third choice (f(x) = –3x3 + 2) have x³ so these are not quadratic function.

In the function: <span>f(x) = –3x2 – 3x + 2
</span>a = -3
c = 2

In the function: f(x) = 2x2 + 3x – 3
a = 2
c = -3

Six less than seven times a number is equal to -20
zmey [24]
Let this number be x.
"Six less than seven times a number is equal to -20" can be represented by the equation 7x - 6 = -20. We need to solve for x.
First, add 6 from each side so we can have the variables on a side and the numbers on the other:
7x - 6 + 6 = -20 + 6
7x = -14
Then, you divide each side by 7 so we can get the variable x alone on a side, and its value on the other side:
(7x)/7 = -14/7
x = -2

You can re-check your answer (very important):
7x - 6 = 7 (-2) - 6 = -14-6 = -20
The answer has been approved.

Hope this Helps! :)
