According to PEMDAS

Multiplying/dividing comes first when you read the equation from left to right

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x - 10
-
A)
The vertex form is y = (x - 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 - 10.
C)
The vertex form is y = -(x - 2)2 - 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).

Answers

Answer:

Step-by-step explanation:

The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not

y = -x² + 4x - 10 ?

y = -(x² - 4x) - 10

y = -(x² - 4x + 2²) + 2² - 10

y = -(x-2)² - 6

the vertex is a maximum at (2,-6)

a₂₀ = 69

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 12 and d = 15 - 12 = 3 , then

a₂₀ = 12 + (3 × 19) = 12 + 57 = 69

3(x + 1) - 2x = -6 what’s the answer??

Answers

Answer:

x=−9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(x+1)−2x=−6

(3)(x)+(3)(1)+−2x=−6(Distribute)

3x+3+−2x=−6

(3x+−2x)+(3)=−6(Combine Like Terms)

x+3=−6

x+3=−6

Step 2: Subtract 3 from both sides.

x+3−3=−6−3

x=−9

James is participating in a 3-mile walk to raise money for a charity. He has received $300 in fixed pledges and raises $13 extra for every mile he walks. Use a point-slope equation to find the amount he will raise if he completes the walk.

Answers

Answer: $339

Step-by-step explanation:

Given

The total length of the journey is 10 miles

fixed pledges are $300

variable pledges are $13 per mile

Point slope equation form is

[tex]\Rightarrow y=mx+c[/tex]

Here the total charge corresponds to y and miles walked corresponds to x

So, we can write

[tex]T=13\times m+300[/tex]

where,

[tex]T=\text{Total charge}\\m=\text{miles walked}[/tex]

for 3 miles distance

[tex]\Rightarrow T=3\times 13+300=\$339[/tex]

Find the area of the parallelogram.

Answers

Answer:

36 ft^2

Step-by-step explanation:

I) Find dimensions:

The base is 9 feet, and the height is 4 feet.

(Remember, 6 ft is not the height because that is the height of the parallelogram's parallel sides.)

II) Find area:

Area = base x height

A = B x H

36 = 9 x 4

III) Find unit:

Make sure to add the unit, it is ft^2 or ft² since this figure is three-dimensional and measured in feet.

How many degrees is arc PQ?

Answers

Answer:

Step-by-step explanation:

Arc PQ is 60°

Answer:

[tex]\boxed {\boxed {\sf Arc \ { PQ } = \ 60 \ degrees}}[/tex]

Step-by-step explanation:

The angle that forms arc PQ is a central angle, because the angle's vertex is at the center of the circle.

According to arc-angle relationships, the measure of a central angle is equal to the arc.

Since the central angle is equal to 60 degrees, arc PQ is also equal to 60 degrees.

Write both sides as powers of 2. First,

so the equation can be rewritten as

Recall that [tex](a^b)^c=a^{bc}[/tex], so that
