Which of the following graphs is described by the function given below?
y = 2x2 + 6x + 3

Answer:

=>x=4

therefore y= -19

Answer:

x = 4, y = - 19

Step-by-step explanation:

Given the 2 equations

5x + y = 1 → (1)

10x - 6 = 34 → (2) , which can be solved as

10x = 40 ( divide both sides by 10 )

x = 4

Substitute x = 4 into (1) and solve for y

5(4) + y = 1

20 + y = 1 ( subtract 20 from both sides )

y = - 19

The region D represents the solution of the given system of inequalities.

A system of linear inequalities is a collection of linear inequalities in the same variables.

According to the given equation.

We have system of inequalities.

[tex]y < \frac{-1}{2}x[/tex]

and [tex]y \geq 2x + 3[/tex]

Also, the graph of the inequalities.

Since, y is less than [tex]-\frac{1}{2} x[/tex] shade  below the line.

And, for the second inequality.

y is greater than and equal to 2x + 3 therefore, shade the above the line.

So, the common region D we get after the shading.

Hence, region D represents the solution of the given system of inequalities.

Answer:

the surface area is 3140 square feet

Step-by-step explanation:

The computation of the surface area is given below:

Given that

Diameter = 20 feet

radius =  20 ÷ 2 = 10 feet

Surface area =  

= 2 × 3.14 × (10)^2 + 2 × 3.14 × 10 × 40

= 6.28  × 100  + 6.28  × 400

= 628 + 25.12  × 100

= 628+ 2512

= 3140 square feet

hence, the surface area is 3140 square feet

The surface area is 3140 feet².

Surface area is the amount of space covering the outside of a three-dimensional shape.

Given that:

Diameter = 20 feet

radius =  20 ÷ 2 = 10 feet

Now, Surface area  will be,

=2πr²+ 2πrh

= 2 × 3.14 × (10)² + 2 × 3.14 × 10 × 40

= 6.28  × 100  + 6.28  × 400

= 628 + 25.12  × 100

= 628+ 2512

= 3140 feet²

hence, the surface area is 3140 feet².

Answer:

19.53

Step-by-step explanation:

First let's find the new price of the backpack:

40% of 29.99 is

29.99 * 0.40 = 11.99

So the new price of the backpack is

29.99 - 11.99 = 18.00

Now let's find the price with tax

8.5% of 18.00 is

18.00 * 0.085 = 1.53

So the cost of the backpack is

18.00 + 1.53 = $19.53

Answer:

$19.52

Step-by-step explanation:

29.99 x 0.60 = 17.994, (60% of 29.99)

1.085 x 17.994 = 19.52349 = $19.52 (2dp) , - (Add 8.5% Tax)

Answer:

= -5[tex]x^{4}[/tex] - 1/5

0r

-5[tex]x^{4}[/tex] - 0.2

Step-by-step explanation:

Volume of a rectangular prism = area of base x height

-5[tex]x^{5}[/tex] - 1 = 5x + 5 x area of the base

to determine the area of the base, divide both sides of the equation by (5x + 5)

area of the base =  (-5[tex]x^{5}[/tex] - 1)  / (5x + 5)

Hello,

We know that :

a * b = ab² - a²b

We know that : 2 * 3 = 6 but we want to try this formula.

We have :

a = 2 and b = 3

So :

2 * 3

= 2 * 3² - 2² * 3

= 2 * 9 - 4 * 3

= 18 - 12

= 6

Answer:

Line A

Step-by-step explanation:

A line of symmetry is a line that divides a shape into exactly two equal halves.

A triangle is a polygon with three sides and three angles. A scalene triangle has no lines of symmetry, an isosceles triangle has more than one line of symmetry while an equilateral triangle has three lines of symmetry.

From the diagram we can see that line A divides the figure into two equal halves, hence line A is the line of symmetry.

Answer:

B) Rotation

Step-by-step explanation:

The arrows at the end of each line imply a line, not a line segment. Since the they both pass through the origin, they rotate about the origin, hence B) Rotation.

Answer: 24, b

Step-by-step explanation:

So it said "In the Math Club", 67% are not in the literature club. We also know that this 67% is 16 people.

Now we can set up an equation to find the total number of people in the math club. Let's say the total number of people in the Math club is x, so 0.67x = 17, and x = 25.37 rounded. So if 25 people in total, 16 not in the literature club, then that means 25-16 = 9 people are in both the Math club and the Literature club.

So of the students "Not in the Math Club", it said that 78 percent are not in the Literature Club. This means 22 percent are in the literature club. We also know 4 people are in the literature club.

Now we can set up an equation to find the total number of people not in the math club. Let's say the total number of people not in the Math club is x, so 0.22x = 4, x = 18.18 rounded. So if 18 in total, 4 in the literature club, than 14 not in the literature club.

Since x = 9, and y = 14, x+y will equal 23, rounding up to 24 since we rounded down the total number of people.
