Answer:

See below.

Step-by-step explanation:

The graph of the quadratic equation is a parabola or u shaped graph. It has a vertex at (-1,-3) since h=-1 and k=-3 in the vertex form. It is also facing down since the leading coefficient is negative.

Find the missing angle measures of the following figure

Lisa [10]

Answer:

1 = 68

2 = 68

3 = 125

Step-by-step explanation:

Hey there!

To find angle 1 all we have to do is subtract the given angles from 180 because remember all of the angles in a triangle add up to 180

180-73-39=68

1=68

angle 2 is vertical to angle 1 therefore they are congruent angles so

2 also equals 68

So we know that the interior angles in a 4 sided shape add up to equal 360

so to find 3 we subtract the given angles from 360

360-90-77-68=125

so 3 = 125

Evaluate the expression.

EastWind [94]

Answer:

Step-by-step explanation:

We use (BODMAS) :

Brackets

Order/Index

Division

Multiplication

Addition

Subtraction

Now we do bracket first :

7(3²) = 7(9) = 63

Now we do division :

63÷3 = 21

Now we do multiplication :

2 × 21 = 42

Hope this helped and have a good day
