Answer:
y = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 1,2) and (x₂, y₂ ) = (4, y)
m = 
, hence
= - 
( cross- multiply )
5(y - 2) = - 20 ( divide both sides by 5 )
y - 2 = - 4 ( add 2 to both sides )
y = - 2
coordinates of point are (4, - 2)
Answer:
4y^2-12y
Step-by-step explanation:
y^2+4y-16y+3y^2
=y^2+3y^2+4y-16y
=4y^2+4y-16y
=4y^2-12y
The total distance will be 8685.2 kilo meters if she travelled by plane
Answer:
initial cost per issue=$2
after subscription cost per issue=$1.6.
Step-by-step explanation:
Initially , Mei subscribed $24 for 12 issues for a magazine .When Mei used a coupen then 3 free bonus issues added to her subcsription .Therefore we can see the coupon reduces the cost per issue of Mei's subscription. Before use of coupon the cost of each issue is $2 and after added 3 more issue of coupon then the cost per issue is $1.6
The equation in the form of the given expression is (0)² + (1)² = 1
<h3>Trigonometry identity</h3>
According to some of the trigonometry identity
sin 0 = 0
cos 0 1
Given the expression below
sin^2 0+cos^2 0=1
This can also be expressed as:
(sin0)² + (cos0)² = 1
Substitute
(0)² + (1)² = 1
Hence the equation in the form of the given expression is (0)² + (1)² = 1
