Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2,2) and (x₂, y₂ ) = (8, 5) ← 2 points on the line
m =
=
= 
the line crosses the y-axis at (0, 1) ⇒ c = 1
y =
x + 1 ← equation in slope- intercept form
The answer to this one is<em> xy + 4</em>
Answer:
The percentage = (1.06/15.9) x 100℅
= 6.67℅
Step-by-step explanation:
For the two pan to be balanced in other to measure an object's accurate weight, the fulcrum must be exactly in the mid point of the distance/separation between the two pans.
In the case in this question, the dishonest shopkeeper has shifted the fulcrum by 1.06cm.
The pan separation is 31.8cm
The fulcrum position must be 31.8/2 = 15.9cm, for it to be balanced.
The percentage by which the true weight marked up by the shopkeeper is:
(1.06/True fulcrum position) x 100℅
2.40 / 8 = 0.3
0.3 * 3 = 0.9
Answer: 0.9 is 3/8 of 2.40
Answer:
Step-by-step explanation:
Pay attention to order of vertices when comparing the congruent parts or figures.
C and D as well as B and E are corresponding vertices according to angle marks and side marks.
