Answer:
PEMDAS
Step-by-step explanation:
The first one and the last one
Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)
Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)
Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.
Hello: <span>
<span> an equation is : y =ax+b ( a is a slope )
parallel to the line (q) : y=6/5x-1 a =6/5 ( same slope
)
the equation of (r) : is : y = 6/5x+b</span></span>
the line through point (5,5) :
5= (6/5)(5)+b ...b=-1
an equation of (r) : is : y = 6/5x-1
or : 6/5x-y = 1
The kite area can be calculated using the formula
a = 1/2 × d₁ × d₂
with d₁ as first diagonal and d₂ as second diagonal
From the question, we know that
d₁ = 9.5 + 9.5
d₁ = 19 in
d₂ = 7 + 12
d₂ = 19 in
Calculate the area by plugging in the numbers into the formula
a = 1/2 × d₁ × d₂
a = 1/2 × 19 × 19
a = 1/2 × 361
a = 180.5
The area of the kite is 180.5 in²
The answer is fourth answer
