Answer:
<em>y ≥ - 0.8 </em>
Step-by-step explanation:
= 5y + 4
= 5y + 4
5y + 4 = 5y + 4 and 5y + 4 ≥ 0 ⇒ y ≥ - 0.8
y ∈ [ - 0.8 , ∞ )
- ( 5y + 4 ) = 5y + 4
10y = - 8
y = - 0.8
The answer is <em>y ≥ - 0.8</em>
Answer:
x≤16
Step-by-step explanation:
1/2x - 3 ≤5
Add 3 to each side
1/2x -3+3 ≤5+3
1/2x≤8
Multiply each side by 2
1/2x*2 ≤8*2
x≤16
Step-by-step explanation:
Given:
2x−y=7
Matching given equation with the variables,
a=2
and
b=−1 .
Swap "a" and "b"
-x + 2y = 7
Because b is negative, let's change that one:
x + 2y = 7
Is perpendicular to
2x−y=7
. Here is a graph to prove it:
The red line is
2x−y=7
The blue line is
x+2y=7
If you want the perpendicular line to go through a given point, then make the constant term on the right a variable (for example k)
x+2y=k
Now lets make the perpendicular line go through the point
(1,1)
by substituting 1 for x, 1 for y and the solving for k:
1+2(1)=k
k=3
The equation of the line that perpendicular to
2x−y=7 and goes through the point
(1,1)is:
x+2y=3

X = -10
Because it is the "absolute value" of "10"
Here's why
-X - 10 = 0, right ?
So, now we have to add a positive 10 to each of our sides to get one step closer to our answer
-X + 10 = 0 ⬅️cancel this
0 + 10 = 10 ⬅️keep this
We can multiply by a negative 1 (-1 )
10(-1) = -10
0(-1) = -0
So that's how we found out that X = -10
