Answer:
3x + 5 = 30
Step-by-step explanation:
Tate has 2x + 5 pennies and since Tate and Mia have 30 pennies all together you would add an x to the equation of how many pennies Tate has and set it equal to 30 making the equation 3x + 5 = 30
<span>A matrix is basically a table of columns and rows.
One way to use an array is to tabulate information concerning two variables, for example, sizes of shoes and person's height, or price of different kinds of vegetables over 12 months, etc.
So for your problem, think of two variables that you can tabulate in your sports team. If you are out of ideas, read the sports page.</span>
Given: <span>2x-y-3=0.
find </span>equation for the line perpendicular to the given line that goes through the given point:<span>
(2;-1)koord of direction vector (i`m not know how it is called at you, because i'm from russia)</span><span>
=> (x-0)/2=(y-4)/-1 (</span>canonical <span>equation)
=>x+2y-8=0(general </span><span>equation)
</span>
<span>further:
{x+2y-8=0
{2x-y-3 =0 => y=13/5 x=14/5
(14/5; 13/5) - koord point on line
</span>|dist|=sqrt( (14/5-0)^2 + (13/5-4)^2 ) = sqtr(7.72) = 2.78
Удачи!
