Answer:

[tex]x=-4,\:x=-\frac{1}{5}[/tex]

Step-by-step explanation:

The zeroes of the function [tex]g(x)=(-5x-1)(2x+8)[/tex] can be found by setting [tex]g(x)[/tex] to [tex]0[/tex], then solving for [tex]x[/tex]:

[tex](-5x-1)(2x+8)=0[/tex]

When either term is [tex]0[/tex], the equation is true. Therefore we have two cases:

[tex]\begin{cases}-5x-1=0,\: -5x=1, \:\fbox{$x=-\frac{1}{5}$}\\2x+8=0,\:2x=-8,\:\fbox{$x=-4$}\\\end{cases}[/tex]

Form the given function lesser x value is -4 and the greater x value is -1/5.

The zeros of a function are defined as the values of the variable of the function such that the function equals 0. Graphically, the zeros of a function are the points on the x-axis where the graph cuts the x-axis. In other words, we can say that the zeros of a function are the x-intercepts of its graph. The number of zeros of a polynomial function is equal to the degree of the polynomial.

The given function is g(x)=(-5x -1)(2x +8)

Now, (-5x -1)(2x +8)=0

(-5x -1)=0 and (2x +8)=0

-5x=1 and 2x=-8

x=-1/5 and x=-4

Therefore, form the given function lesser x value is -4 and the greater x value is -1/5.

Answer:

The concession stands needs to sell 14 or more bags.

Step-by-step explanation:

Given that:

Cost per bag of popcorn = $2.50

Number of bags already sold = 30

Cost of 30 bags = 30*2.50 = $75

Bags needs to be sold to make $110 = x

2.50x + 75 ≥ 110

2.50x ≥ 110-75

2.50x ≥ 35

Dividing both sides by 2.50

[tex]\frac{2.50x}{2.50}\geq \frac{35}{2.50}\\x\geq 14[/tex]

Hence,

The concession stands needs to sell 14 or more bags.

Answer:

176.

Step-by-step explanation:

112 = 2*2*2*2*7

For a cube number there must be 3 or a multiple of 3 of each factor.

So we multiply  by 2*2 and 7 * 7 to give 2^6 * 7^3 which is 21952.

The answer is 4*49

= 176.

Checking that 21952 is a cube:

- the cube root is 28,

area = L x W

where L = 9x⁸

          W = 6x⁵

plugin values into the formula:

Area = 9x⁸ * 6x⁵

        = 54x¹³

The area of the rectangle as an expression of x is [tex]2160x^3[/tex] square feet.

To find the area of the rectangle, we can use the formula for the area of a rectangle, which is:

Area = length × width

Given that the width is 6x5 feet and the length is 9x8 feet, the area of the rectangle is:

Area = (9x8) × (6x5)

To simplify the expression, multiply the coefficients and combine the variables:

[tex]Area = 54x^2 * 40x[/tex]

Now, multiply the coefficients:

[tex]Area = 2160x^3[/tex]

So, the area of the rectangle as an expression of x is [tex]2160x^3[/tex] square feet.

Answer:

y=-1x-2

Step-by-step explanation:

hope it helps ^^

Answer:

y = -x - 2

Step-by-step explanation:

Since we have a straight, linear line, the line follows the y = mx + b format

The line moves one unit down for every unit to the right, making m = 1

Since the line has a downward slope, m = -1

Since the line crosses the y-axis at -2, b = -2

Therefore, the equation is y = -1x - 2 or more simplified, y = -x - 2

Answer:

x=4

y=6

Step-by-step explanation:

We need to find value of x and y if RS bisects AB and RS = 28

We are given: RS = 28

and We can see from figure that: RT= 3y-7 and TS = 2y+5

And we can observe that RT + TS = 36

So, putting all the values, we can find value of y

[tex]3y-7+2y+5=28[/tex]

Solving this equation, will find value of y

[tex]3y+2y+5-7=28\\5y-2=28\\5y=28+2\\5y=30\\y=\frac{30}{5}\\y=6[/tex]

So, we get value of y: y=6

Now, we also know that RS bisects the line AB. It means it divides both the lines equally.

So, we can write: AT = TB

Putting values we can find value of x

We have AT = 4x-2

TB = 4y+2

and y =6

[tex]4x-2 = 4y+2\\4x-2=4(6)+2\\4x-2=12+2\\4x=14+2\\4x=16\\x=\frac{16}{4}\\x=4[/tex]

So, we get value of x: x=4

The range is: 7

Step-by-step explanation:

Given the data set

6, 7, 13, 10

Sorting in ascending order

6, 7, 10, 13

We know that the range is the difference between the highest and lowest values in a set of numbers.

Here:

Thus,

Range = Highest Value - Lowest Value

           = 13 - 6

           = 7

Therefore, the range is: 7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be A

Now , the value of A is = 16 cm

Let the second number be = B

The value of B is = 20 cm

The ratio of A and B is calculated as C

where C = A / B

A goes to the numerator of the fraction and B to the denominator

Substituting the values in the equation , we get

C = A/B

C = 16/20

On simplifying the equation , we get

C = 4/5

Therefore , the value of C is 4 : 5

Hence , the value of equation is 4 : 5

AB BC AC

(I’m not sure, If Im wrong let me knoww ❤️❤️)

Answer:

AC BA BC shortest to longest.

Step-by-step explanation:

All triangles have 180o in their interior angles. So A + B + C = 180

5x - 4 + 2x + 3 + 3x - 9 = 180      Combine the like terms on the left.

10x - 10 = 180                               Add 10 to both sides

10x - 10 + 10 = 180 + 10

10x = 190

x = 190/10

x = 19

So <A = 5x - 4 = 91

<B = 2x + 3 = 41

<C = 3x - 9 = 48

Total             180

So the largest Line is opposite 91 and it is BC

The Middle sides line is opposite 48 and it is BA

The smallest line is  opposite 41 and it is AC

AC BA BC shortest to longest.

Answer:

247 cards

Step-by-step explanation:

Misha : Carlos = 9 : 4

Carlos = 76 cards

Misha = x cards

9 : 4 = x : 76

9/4 = x/76

Cross product

9 * 76 = 4 * x

684 = 4x

x = 684 /4

x = 171

Misha = 171 cards

how many cards do they have together?

Total cards altogether = Misha + Carlos

= 171 cards + 76 cards

= 247 cards

Total cards altogether = 247 cards

Answer:

A = 240π cm²

Step-by-step explanation:

Given that,

Height of a cylinder, h = 7 cm

Volume of the cylinder, V = 448π cm³

We need to find the total surface area of the cylinder.

The formula for the volume of the cylinder is given by :

[tex]V=\pi r^2 h\\\\r=\sqrt{\dfrac{V\pi }{\pi h}} \\\\r=\sqrt{\dfrac{448\pi }{\pi \times 7}} \\\\r=8\ cm[/tex]

The formula for the total surface area of the cylinder is given by :

[tex]A=2\pi r(r+h)\\\\A=2\pi \times 8\times (8+7)\\\\A=240\pi \ cm^2[/tex]

So, the total surface area of the cylinder is 240π cm².
