Given :
- Area of square equals to the area of rectangle of sides 4.9m and 1.6m .
To find :-
Solution :-
<u>As </u><u>we</u><u> know</u><u> </u><u>,</u>
- Area = side²
- 4.9 * 1.6 = a²
- a = √ 49/10 * 16/10
- a = 7/10 * 4/10
- a = 28/100
- a = 0.28 m

(2x - 1)(4x + 1) = 0
2x - 1 = 0; x = 1/2
4x + 1 = 0;x = -1/4

Answer:
y = -
x + 
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 )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, - 3) and (x₂, y₂ ) = (- 1, 4)
m =
=
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 4), then
4 =
+ c ⇒ c = 4 -
= 
y = -
x +
← equation of line
Answer:
y=-5
Step-by-step explanation:
every point on a horizontal line has the same y-value. use y-value of the point to find the horizontal-line equation.
