Answer:

1 < a < 13/5

Step-by-step explanation:

2 < 2a - 3(1 -a) < 10

2 < 2a - 3 + 3a < 10

2 < 5a - 3 < 10

2 + 3 < 5a - 3 + 3 < 10 + 3

5 < 5a < 13

5/5 < 5a/5 < 13/5

1 < a < 13/5

: Find the slope between the two points given. Then, use the slope and point ONE to write the equation of the line in Point-Slop
Ierofanga [76]

Answer:

           slope:      \bold{m=3}

      equation:     \bold{y-2=3(x-1)}

Step-by-step explanation:

m=\dfrac{y_2-y_1}{x_2-x_1}\\\\(1,\,2)\ \implies\ x_1=1\,,\ y_1=2\\(0,\,-1)\ \implies\ x_2=0\,,\ y_2=-1\\\\m=\dfrac{-1-2}{0-1}=\dfrac{-3}{-1}=3

y-y_1=m(x-x_1)      - point-slope form of Equation of the Line

x_1=1\,,\ y_1=2\,,\ m=3\\\\equation:\\{}\qquad\qquad y-2=3(x-1)

find the value of c that makes each trinomial a perfect square. then write the trinomial as a perfect square. the equation , x^2
mr Goodwill [35]
Therefore, the value of C should be (11/2)^2

<span>To square a fraction, take the square of the numerator and put it over the square of the denominator. So since 11^2=121 and 2^2=4, (11/2)^2
(11)^2/(2)^2=121/4
</span>
