Answer:
Check whether the first and last terms of the trinomial are perfect squares.
Multiply the roots of the first and third terms together.
Compare to the middle terms with the result in step two
If the first and last terms are perfect squares, and the middle term’s coefficient is twice the product of the square roots of the first and last terms
Step-by-step explanation:
Hello! First off, Staci is buying a ticket for herself, which costs $87.96. She has $200 with her. 200 - 87.96 is 112.04. Now, the t-shirts cost $30 each. We can divide the amount she has left by 3 to get the number of shirts she ca=an buy. 112.04/30 is 3.73466666, but you can't have part of a shirt. Therefore, the maximum amount of t-shirts Staci can purchase is 3.
<span>The three equations can be written as 1) y = 2x - 5 ; 2) y = 2x - 3 and ;3) y = 2x + 5. Now, the slope can be found by slop intercept form of linear equation i.e. y = mx+b where m is the slope. From the above equations, we can see that all the the three have the same slope i.e. m = 2.</span>
Step-by-step explanation:
Given points ( 2 , 7) and ( - 8 , 1 )
Distance between two points
Therefore distance between two points is 4 units.
