Write an inequality to represent the graph.
The inequality which correctly represents the graph as represented in the task content is; y ≤ ( -1/4 ) x + 2.
Which inequality correctly represents the given graph?First, to determine the inequality which represents the graph given, it is important to determine the equation of the border line as follows;
Since the slope formula is; m = (y₂ - y₁) / (x₂ - x₁).
Hence, given points; ( 0, 2 ) and ( 4, 1 ).
Slope, m = ( 1 - 2 ) / ( 4 - 0 )
m = -1 / 4 and y-intercept = 2.
Therefore, it follows from the slope-intercept form equation; y = mx + c that the equation of the boundary line in discuss is;
y = ( -1/4 ) x + 2.
On this note, since the region shaded on the graph is the region below the boundary line and the boundary line is a solid line;
It follows that the required inequality which the graph represents is; y ≤ ( -1/4 ) x + 2.

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answer:
20/10 --> 2/1
Step-by-step explanation:
So, the original rise is 20 and the original run is 10. You wanted it in the SIMPLEST form, so 20/10 in simple is 2/1.

Which fraction is closest to zero?
The fraction 1/3 lies between 1/4 and 1/2 so it it the closest among all the other fractions.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
The fraction 3/4 is greater than 1/2 and less than 1 so it lies in between
1/2 and 1.
The fraction 1/3 is greater than 1/4 and less than 1/2 so it lies between
1/4 and 1/2.
The fraction - 3/6 is - 1/2.
The fraction - 5/8 is greater than - 1/2 and less than - 1 so it lies between
- 1 and - 1/2.
Therefore, The fraction 1/3 is closest to zero.

An engineer charges £20 plus £p per hour to repair central heating boilers.
At one house a repair takes 3 hours and costs £71.
(a)
(b)
(c)
Determine the value of p.
Write down a formula for the cost, £C, of a repair that takes x hours.
A repair costs £96.50. How long does it take?
Answer:
the value of p is £3.67.
Step-by-step explanation:
(a) To determine the value of p, we need to use the information given in the problem to set up and solve a simple equation. The cost of the repair at one house was £71, and it took 3 hours, so the cost per hour was £71 / 3 = £<<71/3=23.67>>23.67 per hour. The engineer charges £20 plus £p per hour, so £23.67 per hour is equal to £20 + £p. Subtracting £20 from both sides gives us £p = £3.67. Therefore, the value of p is £3.67.
(b) The formula for the cost, £C, of a repair that takes x hours can be written as: £C = £20 + (£p * x). This formula states that the cost of the repair is equal to the fixed cost of £20, plus the cost per hour (£p) multiplied by the number of hours (x) that the repair takes.
(c) To determine how long a repair that costs £96.50 takes, we can use the formula from part (b) and solve for x. Substituting in the known values, we get: £96.50 = £20 + (£3.67 * x). Subtracting £20 from both sides gives us: £76.50 = (£3.67 * x). Dividing both sides by £3.67 gives us: x = 20.89 hours.

-5(1/6-8) = 40 - х + 1/6х
w/ solutions pleasee thanks
The value of x in the equation -5(1/6-8) = 40 - х + 1/6х is 1
What are algebraic equations?An algebraic equation can be defined as a mathematical statement in which two expressions are set equal to each other. The algebraic equation usually consists of a variable, coefficients and constants.
The algebraic equation -5(1/6-8) = 40 - х +( 1/6)х has one variable which is x.
Firstly, we open the parentheses
-5/6 +40 = 40-x+(1/6) x
multiplying through by 6
-5+240 = 240-6x +x
collecting like terms
-5+240-240 = -5x
- 5 = -5x
divide both sides by -5
x= -5/-5
x= 1
therefore the value of x is 1
