➷ Pick any two sets of values
I will just select the first two:
(-2,-9) , (1,3)
First, you need to find the slope
slope = difference in y values / difference in x values
slope = (3-(-9)) / (1-(-2))
slope = 12 / 3
slope = 4
Substitute the slope into the general equation of a line form with one of the coordinates:
3 = 4(1) + c
3 = 4 + c
c = -1
The equation would be y = 4x - 1

Answer:
x = 9
Step-by-step explanation:
The question is shown in the attached figure.
We can see that, (8x + 5)° and (13x – 14)° forms a linear pair. It would mean that,
(8x + 5)° + (13x – 14)° = 180°
21x-9 = 180°
21x = 180° + 9
21x = 189
x = 9
Hence, the value of x is 9.
The equation of the circle:
where:
(a; b) - coordinates of the center
r - a radius
Use:
We have:
Answer:The center: (-2; 4)The radius: r = 4
Its less than bc if you turn them into decimals, 15/53 would be 0.42 and 12/20 would be 0.60
Answer:
x = 5 and -2
Step-by-step explanation:
Given the function of x to be;
f(x) = (x-5)(x+2)/x+1
The value of x that will make the function zero can be calculated for by equating the given function to zero first to have;
If f(x) = 0, then;
(x-5)(x+2)/x+1 = 0
Cross multiplying;
(x-5)(x+2) = 0
(x-5) = 0 and x+2 = 0
x = 5 and x = -2
The value of x that will make the function zero is therefore 5 and -2
