Answer:

Step-by-step explanation:
Equation of a line is given as:
y = mx + b
Where
m is the slope
and
b is the y-intercept (y-axis cutting point)
Since we know slope is -4, we can write:
y= mx + b
y = -4x+ b
Given the point (-2,7) , we can say:
x = -2
and
y = 7
Plugging these 2 values, we can solve for b:
y = -4x + b
7 = -4(-2) + b
7 = 8 + b
b = 7 - 8
b = -1
Now, we have the equation:

Answer:

Step-by-step explanation:
we have
closed circle on 2 to closed circle on 6
That means -----> All real numbers greater than or equal to 2 and less than or equal to 6
In interval notation is ------> [2,6]
In set builder notation is ----> { x ∈ R | x ≥ 2 and x ≤ 6 }
Answer:
7pi/6
Step-by-step explanation:
Using the formula for arc length in radians, we get:
- 14pi = 12(theta)
- theta = 7pi/6 [divide both sides by 12]
Answer: 38.25
Step-by-step explanation: You divide the whole number by the denominator in the fraction.
153/4 = 38.25
Answer:
30,000 tiles
Step-by-step explanation:
Area of tile = 250mm^2 = 0.25m^2
Total area of kitchen = 3*2.5 = 7.5m^2
No of tiles = 7.5/0.25 = 30,000 tiles
