solve the equation 3x+12=19 show your work

Answers

Answer 1

[tex]x = 2.3333[/tex]✅

Step-by-step explanation:-

[tex]3x + 12 = 19 \\ ➡ \: 3x = 19 - 12 \\ ➡ \: 3x = 7 \\ ➡ \: x = \frac{7}{3} \\ ➡ \: x = 2.3333[/tex]

To verify:-

[tex]3x + 12 = 19 \\ ➡ \: 3 \times 2.3333 + 12 = 19 \\ ➡ \: 6.9999 + 12 = 19 \\ ➡ \: 19 = 19 \\ ➡ \: L. H. S. =R. H. S. [/tex]

Hence verified.

(btw I hate rose graphs...)

Answer:

Rose curve equations have two forms: r = a cos(nθ) and r = a sin(nθ) where a ≠ 0 and n is a positive integer. Petals have length determined by a. If n is odd, the number of petals is n. However, if n is even, the number of petals is 2n.

Stephanie is hosting an art show and she would like to raise at least $800. She plans on
selling VIP tickets to her family and friends for $20 each. She will also sell general admis-
sion tickets for $40 each. The venue is small, so Stephanie can sell no more than 25 total
tickets.

Answers

Answer: 10, 15

Step-by-step explanation:

Given

Stephanie wants to raise at least $800

she plans on selling VIP tickets for $20 each and general admission for $40 each

suppose there are x and y tickets for VIP and general admission

[tex]\therefore x+y\leq 25\\\\\Rightarrow 20x+40y\geq 800[/tex]

solving above two inequality

Stephanie must sell 10 tickets for VIP and 15 tickets for general admission

Look at the graph of the function f(x).
Which statements regarding the parabola's axis of symmetry are true? Select all that
apply.

A. The axis of symmetry is the line represented by x =
0.

B. The y-axis is the axis of symmetry.

C. If the point (a,b) is a point on the parabola, then the point (-a,b) is also a point on the parabola, because it is a reflection over the axis of symmetry.

D. The X-axis is the axis of symmetry.

Answers

Answer:

Options A, B, C

Step-by-step explanation:

From the graph attached,

Vertex of the given quadratic function → (0, 1)

Therefore, axis of symmetry → x = 0

Option A

Axis of symmetry ix the line represented by x = 0.

True

Option B

The y-axis is the axis of symmetry.

Line represented by x = 0 is the y-axis.

True

Option C

If the point (a, b) is a point on the parabola, then the point (-a, b) is also a point on the parabola, because it is a reflection over the axis of symmetry.

Rule for the reflection over y-axis is given by,

(x, y) → (-x, y)

Therefore, coordinates of the point (a, b) after reflection over the y-axis will be,

(a, b) → (-a, b)

True

Option D

The x-axis is the axis of symmetry.

False

Is this table of values linear?

Answers

Answer:

No

Step-by-step explanation:

Linear values will increase by a common difference. For example, a linear function might increase by 6 every time or -4. However, this table does not; each time it increases by a different factor. Since there is no common difference and it does not follow an arithmetic function it is not linear.

Answer:

Step-by-step explanation:

Not linear.

If the inputs were 1, 2, 3, 4 and we wanted a linear function, one such function would be 1, 2, 3, 4 or 10, 20, 30, 40, and so on.

The given table shows that y increases faster and faster as x increases.

From x = 1 to x = 2, y increases from 1 to 2 (an increase of 1).

From x = 2 to x = 3, y increases from 2 to 6 (an increase of 4).

From x = 3 to x = 4, y increases from 6 to 24 (an increase of 18)

No, the table does not represent a linear function.

What is the circumference of the half circle?

Answers

Answer:

4π cm

Step-by-step explanation:

GIVEN :-

Diameter of half circle = 8cm

TO FIND :-

Circumference of half circle

FACTS TO KNOW BEFORE SOLVING :-

Circumference of a circle with radius 'r' is = [tex]2\pi r[/tex]

⇒ Circumference of half-circle with radius 'r' = [tex]\frac{2\pi r}{2} = \pi r[/tex]

SOLUTION :-

Radius = [tex]\frac{Diameter}{2} = \frac{8}{2} = 4[/tex]

So , Circumference of half-circle = [tex]\pi \times 4 = 4\pi[/tex] cm

What is the measure of angle "A"?

Answers

Answer:

[tex]<A=106[/tex]

Step-by-step explanation:

The given figure is an isosceles trapezoid, this means that the two non-parallel sides in the trapezoid are congruent. One of the properties of an isosceles triangle is that opposite angles are supplementary. This means that the sum of angles opposite each other in an isosceles trapezoid is (180) degrees. One can apply this here by stating the following,

[tex]<A+<C=180[/tex]

Substitute,

[tex]<A+74=180[/tex]

Inverse operations.
