Answer: Option a: 3y < 10 - 2y
Step-by-step explanation:
A linear inequality is something that can be written as:
y > a*x + b
or
y < a*x + b
So we need to see which inequality of the given ones CAN'T be written in this way.
a) 3*y < 10 - 2*y
Here we can see that we have only one variable, so this can not be a linear inequality.
b) 2*x - y > 6
We can rewrite this as:
y < -6 + 2*x
Then this is a linear inequality.
c) 3x-5y ≥ 15
This can be rewritten as:
y ≤ (3/5)*x - 15/5
Then this is a linear inequality.
d) 23 ≤ 3m - 2n
This can be rewritten as:
m ≥ (2/3)*b + 23/3
This is a linear inequality.
Then the option that is not a linear inequality in two variables is option a.

What is the equation of a circle with the center(-9,-5) and radius equals 9
Answer:
(x+9)^2+(y+5)^2=81
Step-by-step explanation:
(x-h)^2+(y-k)^2=r^2
(h,k)=center
r=radius
so if you just insert the center (-9,-5) and the r with 9
(x-(-9))^2+(y-(-5))^2=9^2
(x+9)^2+(y+5)^2=81
Hope that helps :)
Answer:
(x + 9)^2 + (y + 5)^2 = 81

A creature on the moon throws a rock off a cliff. The height of the rock above the surface of the moon, in meters, t seconds after it is thrown is given by h(t) = -t^2 + 8t + 10. When does the rock hit the surface of the moon?
Plz give step by step solution.
Answer:
Step-by-step explanation:
The rock will hit the surface when its height equals zero.
t^2-8t-10=0
t^2-8t=10
t^2-8t+16=10+16
(t-4)^2=26
t-4=+(26^(1/2))
t=4+(26^(1/2))
t=9.1s

The function g is defined by the following rule.
g(x)=(1/5)^x
Find g(x) for each x-value in the table.
Answer:
[tex]g(-2) = 25[/tex]
[tex]g(-1) = 5[/tex]
[tex]g(0) = 1[/tex]
[tex]g(1) = \frac{1}{5}[/tex]
Step-by-step explanation:
Given
[tex]g(x) = \frac{1}{5}^x[/tex]
Solving (a): When x = -2
This gives:
[tex]g(x) = \frac{1}{5}^{(-2)[/tex]
[tex]g(x) = \frac{1}{5}^{-2[/tex]
[tex]g(x) = 5^2[/tex]
[tex]g(-2) = 25[/tex]
Solving (b) When x = -1
This gives:
[tex]g(x) = \frac{1}{5}^{-1}[/tex]
[tex]g(-1) = 5[/tex]
When x = 0
This gives:
[tex]g(x) = \frac{1}{5}^0[/tex]
[tex]g(0) = 1[/tex]
When x = 1
This gives:
[tex]g(x) = \frac{1}{5}^1[/tex]
[tex]g(1) = \frac{1}{5}[/tex]
