Answer:
-9.4
Step-by-step explanation:
–5.3+(-4.1) =
The signs are alike, so we add and take the sign
5.3+4.1 = 9.4
The sign is negative so we take the negative sign
-9.4
Answer:
x = 14 y = -3x + 3
Step-by-step explanation:
Answer:
y ≥ 3x - 1
y < 
Step-by-step explanation:
Let the equation of the solid line passing through (x', y') given in graph is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of the solid line =
m =
m = 3
y - intercept 'b' = -1
Therefore, equation of the line will be,
y = 3x - 1
Since, shaded (blue) area is above the line, inequality that will represent the solution area will be,
y ≥ 3x - 1
For the dotted line,
Slope of the line (m) = 
= 
= 
y-intercept (b) = 2
Equation of the dotted line → y = 
Since, shaded (grey color) area is below the dotted line,
Inequality representing the solution area will be,
y < 
This is easy, if adding the first number to the second number you get 70.2 then if you want to find the middle number you will have to subtract 32.34 from 70.2 to get 37.86, now add that and 32.34 to check if it gives you 70.2.... When you add them you indeed get 70.2 so your work is correct meaning your middle number is 37.86
Hope this helped
