Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have
Substitute:
Convert to the standard form (Ax + By = C):
multiply both sides by 3
subtract 2x from both sides
change the signs
Answer:
width = 5 m
Step-by-step explanation:
let the width of the room be w then the length = 2w + 5 ( that is 5 more than twice its width )
perimeter is the sum of the sides
for a rectangular room the perimeter is calculated as
perimeter = 2 ( length + width ) = 2(2w + 5 + w) = 2(3w + 5)
given the perimeter is 40 m , then equating
2(3w + 5) = 40 ( divide both sides by 2 )
3w + 5 = 20 ( subtract 5 from both sides )
3w = 15 ( divide both sides by 3 )
w = 5
that is the width of the room is 5 m

Answer:
50% chance
Step-by-step explanation:
The given sentence into an inequality is 5x-9≥-28.
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, nine subtracted from the product of 5 and a number is at least -28.
Let the unknown number be x.
nine subtracted from the product of 5 and a number
5x-9
So, inequality is 5x-9≥-28
Now, 5x≥-28+9
5x≥-19
x≥-19/5
x≥-3.8
Therefore, the given sentence into an inequality is 5x-9≥-28.

Answer:
5x - 9 ≥ -28
Simplifying gives:
x ≥ -3.8
Step-by-step explanation:
Nine subtracted from the product of 5 and a number is at least -28
Let the number be x so;
5x - 9 ≥ -28
5x ≥ -28 + 9
5x ≥ -19
x ≥ -19/5
x ≥ -3.8

the rate is 1 1/3 math papers per every 8 seconds so you could put it as a fraction: (1 1/3 )/8. you would then divide to get 1/6 math papers per second as your answer
Answer:
Reflection about the vertical line x = 2.5 inches will map the square unto itself
Step-by-step explanation:
The given parameters are;
The area of the square = 25 in²
The orientation of the sides of the square are horizontal and vertical
Therefore, we have;
The area, A, of the square given by the following relation;
A = Side²
A = 25 in²
Therefore;
The area of the square = 25 = side²
The length of the sides of the square = √A = √25 = 5
The length of the sides of the square = 5 inches
The reflection of a figure that maps the figure unto itself is a reflection along the line of symmetry
One of the line of symmetry that divides the square into two similar halves is the vertical straight that passes half way through the horizontal side, which is the point 2.5 inches to the right on the x-axis with the coordinates (2.5, 0)
Therefore, reflection about the line x = 2.5 inches will map the square unto itself.
