Answer:
Option (2)
Step-by-step explanation:
Let the equation of the line is,
y - y' = m(x - x')
where (x', y') is a point lying on the given line.
And m = slope of the line = 
Line given in the graph passes through two points (-5, -1) and (-2, -3).
Slope of the line 'm' = 
= 
Therefore, equation of the line passing through(-5, -1) and slope of the line = will be,
y - (-1) = ![-\frac{2}{3}[x-(-5)]](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B3%7D%5Bx-%28-5%29%5D)
Option (2) will be the answer.
Answer:
f(0) = 2
Roots are;
-2 and -1
Step-by-step explanation:
F(0) simply refers to the y-values when x = 0
This is the point at which the graph crosses the y-axis
the value here is 2
To
find the roots of f(x) , we simply find the points at which the plot crosses the x-axis
we have this at x = -2 and x = -1
These are what represents the roots of the equation
Answer:
jil got 18 chocolates
Step-by-step explanation:
let the ratio constants be x,
so, jil has 3x chocolates
katie has 4x chocolates
and we know total chocolates = 42
then,
=》3x + 4x = 42
=》7x = 42
=》x = 42 ÷ 7
=》x = 6
so, jil got 3x = (3 × 6) = 18 chocolates
katie got 4x = (4 × 6) = 24 chocolates
Step-by-step explanation:
x=k/y------(1)
k=xy
k= 7×3
k=21
from equation 1
x=k/y
y=k/x
y=21/9
y = 2.33
