Answer:
Option (D)
Step-by-step explanation:
Equation to represent the household expenditure per week will be in the form of,
y = mx + b
Where m = slope of the line
b = y-intercept
From the graph attached,
Since, line of best fit touches the positive side of the y-axis, y-intercept will be positive.
Since, y-values on the graph are decreasing with the increase in the x-values,
Slope of the graph will be negative.
[Slope =
, Since rise of the line is negative and run is positive, slope will be negative]
By these properties equation of the linear graph will be,
y = -0.34x + 5.19
Option (D) will be the correct option.
1= 6.928203 recurring
2= 3
3= 6.2449979984
4= 17
Answer:
14
Step-by-step explanation:
Given the following equation;
4³ - (2 + 2³) * 5
4*4*4 - (2 + 2*2*2) * 5
64 - (2 + 8) * 5
64 - (10) * 5
64 - 50 = 14
Note: the rule of BODMAS was applied.
Answer: SAS postulate will be use to prove Δ ABD ≅ ΔCBD
Step-by-step explanation:
Here, In ΔABC line segment BD is the perpendicular bisector of line segment AC,
Therefore, BD ⊥ AC and, AD=DC
Thus, In triangles ABD and CBD,
AD≅DC ( given)
∠ADB≅∠CDB ( Right angles)
BD≅BD ( Reflexive)
Therefore, By SAS postulate of congruence,
Δ ABD ≅ ΔCBD.
