damaskus [11]3 years ago

6 0

Answer:

(-2, -1, 0, 3,3)

Step-by-step explanation:

The domain simply refers to the possible x-values the function can take

so by listing out all the x-values of the individual points, we have all the domains

That will be ;

(-2, -1, 0, 3,3)

Solve each equation by completing the square 2q^2+8q=3

3241004551 [841]

Answer:

Divide by 2

q^2+4q=3/2

q^2+4q(4/2)^2=3/2+(4/2)^2

(q+4/2)^2=3/2+16/4

taking the square root of both side

√(q+4/2)^2=√(3/2+16/4)

Note that the square will cancel the square root then you will take LCM on the right hand side

q+4/2=√6+16/4

q+4/2=√22/4

q= -4/2+-√22/4

q=(-4+_√22/4)

The polygons are similar. Solve for x. scale factor from A to B = 3:5

Sonbull [250]

Answer:

Step-by-step explanation:

if scale factor is 3/5, then

(x+12):35=3:5, ⇒

$\frac{x+12}{35} =\frac{3}{5}; x=21-12; x=9$

Given in the figure below, find the values of X and Z.

Answer:

$\boxed{x=9}\\\boxed{z=76}$

Step-by-step explanation:

Hello There!

Geometry

The angles shown represented by the expressions (11x + 5) and (5x+59) are vertical angles

Vertical angles are congruent so we can use this equation to solve for x

Basic Algebra

11x + 5 = 5x + 59

step 1 subtract 5x from each side

5x - 5x cancels out

11x - 5x = 6x

now we have 6x + 5 = 59

step 2 subtract each side by 5

5 - 5 cancels out

59 - 5 = 54

now we have 54 = 6x

step 3 divide each side by 6

6x/6=x

54/6=9

we're left with x = 9

now we want to plug in 9 into x for one of the expression

11(9) + 5

11 * 9 = 99

99 + 5 = 104

so we can conclude that the measure of the angle labeled ( 11x + 5 ) is 104 degrees

Now we need to find z

Geometry

The angle with a measure of 104 and angle Z are supplementary angles meaning that the sum of the two is 180

So to find z we subtract the known angle (104) from 180

180 - 104 = 76

so we can conclude that z = 76
