Which is the graph of the linear inequality y < 3x + 1? On a coordinate plane, a solid straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the left of the line is shaded. On a coordinate plane, a solid straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the right of the line is shaded. On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the left of the line is shaded. On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the right of the line is shaded.
For this case we have the following inequality: y < 3x + 1 < br/ >
What we must do is to evaluate a point of the Cartesian plane and verify if it is in the shaded region.
The shaded region represents the solution of the system of equations.
For the point (0, 0) we have:
0 < 3(0) + 1 < br / >
0 < 0 + 1 < br / >
0 < 1 < br / >
Therefore, the point (0, 0) is in the shaded region because it satisfies the inequality.
Then, the points that are on the line, are not part of the solution because the sign is of less strict.

if the original quantity is 12 and the new quantity is 15, what is the percentage increase? The percent increase is _____%
Answer:
25%
Step-by-step explanation:
Given data
original quantity =12
new quantity =15
% increase= new-original/original *100
% increase= 15-12/12 *100
% increase= 3/12 *100
% increase=0.25 *100
% increase=25%
hence the increase is 25%.

Which digit(s) make the solution of the equations the whole number? 5x-496=1.34...
Answer:
x≈ 100
Step-by-step explanation:
Given the equation
5x-496=1.34...
We are to find the value of x to the nearest whole number
Add 496 to both sides
5x-496+496 = 1.34+496
5x = 497.34
x = 497.34/5
x = 99.468
x ≈ 100
Hence the value of x to nearest whole number is 100

Negative one-fifth of a number, increased
by 3, is at most 1.
The number x ≤ 10 for the inequality (-1/5)x + 3 ≤ 1.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Negative one-fifth of the number, increased
by 3, is at most 1.
Number = x
This can be written as,
(-1/5)x + 3 ≤ 1
Solve for x.
(-1/5)x + 3 ≤ 1
(-1/5)x ≤ 1 - 3
(-1/5)x ≤ -2
x ≤ -2 x (-5/1)
x ≤ 10
Thus,
The number is less than or equal to 10.

3x + 2y = 7
y = -3x +11
Answer:
x=5
Step-by-step explanation:
3x+2(-3x+11)=7
Use distributive property:
3x-6x+22=7
Combine like terms:
-3x+22=7
-3x=-15
Then divide:
-3x/3=-15/3 = 5

Write the equation of the line given the points (2,0) and (3.-1)
Answer:
y = -1x + 2
Step-by-step explanation:
We need to find y = mx + b
Use the following equation
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the values
[tex]\frac{-1-0}{3-2}[/tex] = [tex]\frac{-1}{1} = -1[/tex]
We have found the slope(m) which is -1
We have to find y-int b
Plug in any given x,y into the slope formula
-1 = -1(3) + b
-1 = -3 + b
2 = b
At last the formula is
y = -1x + 2
