Given point doesn't satisfy the inequality

Step-by-step explanation:

In order to check, if an inequality is satisfied by the point or not the point is put in the inequality

Given inequality is:

5x-2y+1>0

Putting the point (-2,-1) in the inequality

5(-2)-2(-1)+1>0\\-10+3+1>0\\-10+4>0\\-6>0

As -6 cannot be greater than zero,

So,

Given point doesn't satisfy the inequality

Transform the given quadratic function into vertex form f(x) = quadratic function into vertex form f(x) = quadratic function int
vesna_86 [32]

Answer:

f(x) = 3(x -\frac{2}{3})^2 -\frac{22}{3}

The vertex is (\frac{2}{3}, -\frac{22}{3})

Step-by-step explanation:

For a general quadratic function the form is:

ax ^ 2 + bx + c

For the function

f(x) = 3x ^ 2 -4x -6

Take common factor 3.

f(x) = 3(x ^ 2 -\frac{4}{3}x - 2)

The values of the coefficients for the function within the parenthesis are the following: a = 1, b = -\frac{4}{3}, c = -2

Take the value of b and divide it by 2. Then, the result obtained squares it.

\frac{b}{2}= -\frac{2}{3}

(\frac{b}{2})^2=\frac{4}{9}

Add and subtract \frac{4}{9}

f(x) = 3([x ^ 2 -\frac{4}{3}x +\frac{4}{9}]- 2-\frac{4}{9})

Write the expression of the form

f(x) = (x-\frac{b}{2})^2 +k

f(x) = 3(x -\frac{2}{3})^2 -\frac{22}{3}

The vertex is (\frac{2}{3}, -\frac{22}{3})

Find the measures of the numbered angles of the parallelogram.
frosja888 [35]

Answer:

1=40

2=140

3=40

Step-by-step explanation:

We know on side

140 and side 2 are equal

1 and 3 are equal

So since 140 and 2 are equal

140*2=280

360 degrees total in any 4 sided shape

360-280=80

80/2=40
