Step-by-step explanation:

hope it helps:))

Answer 2

Answer:

x=-½

x=5

Step-by-step explanation:

2x²-5x-10=4x-5

2x²-5x-10-4x+5=0

2x²-9x-5=0

2x²+x-10x-5=0

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

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

2x+1=0

2x=-1

x=-1/2

x-5=0

x=5

The graph that shows a polynomial function with an even degree is option D.

What is a Function?

A function is a law that relates two variables, a dependent and an independent variable with each other.

The domain and range of a function is always defined, the domain is all the values that can be an input to the function and the range is all the valuess that a function can have.

A function that involves positive integer powers as exponents of a variable in an equation is called a polynomial function, like the quadratic equation,

An even degree polynomial function, represented by y = x², have graphs that either open upwards or downwards.

A function is even if, for each x in the domain of f, f (- x) = f (x).

In an even function, the graph is symetrically along y axis.

The only graph that is symmetrical along the y axis is graph D.

The toll on a highway is based on the number of miles driven. If the toll on a 15-mile stretch of highway is $0.60, find the cost to drive a 80-mile stretch.

Answers

Answer:

$3.20

Step-by-step explanation:

We have

15-mile stretch = $0.60

80-mile stretch = x

Cross Multiply

15 × x = 80 × $0.60

x = 80 × $0.60/15

x = $3.20

Hence, the cost to drive a 80-mile stretch is $3.20

If an exterior Angele of a regular polygon is an integer, what are the possible values of the angle?​

Answers

Answer:

Please read the explanied answer below.

Step-by-step explanation:

As we know that polygon is a shape that consists of at least three sides.The sum of exterior angles of any polygon = [tex]360^{\circ }[/tex]

We also know that a regular polygon has all the angles equal and all sides have the same length.

As we know:

Exterior angle = 360° ÷ No. of sides

When the number of sides changes, the angle also changes. Therefore, we would get different integers as answer.

For example:

In terms of a triangle:

Exterior angle = 360° ÷ No. of sides

                        = 360° ÷ 3 = 120°

In terms of a rectangle:

Exterior angle = 360° ÷ No. of sides

                        = 360° ÷ 4 = 90°

and in the same way

360° ÷ 5 = 72 °

360° ÷ 6 = 60 °

360° ÷ 8 = 45 °

360° ÷ 9 = 40°

and so on.

I hope it may have solved your query.

The school band is selling sweatshirts and baseball caps to raise $9000 to attend a band competition Sweatshirts cost $25 each and baseball caps cost $10 each. The equation 25x + 10y = 9000 models this situation, where x is the number of sweatshirts sold and y is the number of baseball caps sold. The number of shirts sold is 258 X - intercept = y - intercept = How many caps were sold?

x int:
y int:
how many caps were sold? :​

Answers

Answer:

255 caps were sold

Step-by-step explanation:

25x+10y = 9000

25(258) + 10y = 9000

6450 + 10y = 9000

-6450 + 10y = -6450

10y = 2550

2550/10y

y = 255

Answer:

165

Step-by-step explanation:

We solve the first 5

1*(10-1)=9

2*(10-2)=16

3*(10-3)=21

4*(10-4)=24

5*(10-5)= 25

and notice

when you go from 6 on its getting the same number because say 3*(10-3) = 3*7 and 7*(10-7) = 7*3 and 7*3 = 3*7 so

You add the first 5 integer you solved up

9 16 21 24 25 = 95

and then you double it no extra 25

and then you get 165 = answer

Basil, Oscar and Sue share 43 sweets.
Sue gets the largest share.
What is the smallest possible number of sweets Sue could get?

Answers

Answer:

Sue gets the largest share of 15, which is the smallest possible number of sweets Sue could get.

Step-by-step explanation:

Basil, Oscar, and Sue share 43 sweets.

Sue gets the largest share.

Let us divide the 42 sweets by 3

42/3 = 14

It means 3 equal parts of 14 make the sum 4.

i.e. 14+14+14 = 42

Since Basil, Oscar and Sue share 43 sweets, which is 1 plus 42.

So, add that 1 to Sue. i.e. 1+14 = 15

so 15+14+14 = 43

Thus, Sue gets the largest share of 15, which is the smallest possible number of sweets Sue could get.

What is inequality?

A collection of two or more inequalities in one or more variables is known as a system of inequalities. When there are multiple constraints on a problem's potential solutions and a range of potential solutions are needed, systems of inequalities are used. The maximum or minimum values of a situation with multiple constraints are frequently determined using a system of linear inequalities.

It is given that,the sum of a number and 9, divided by 4, is greater than or equal to -2

Suppose the number is n,

(n+9)/4≥-2

n+9≥-8

n≥-8-9

n≥-17

Thus, if the sum of a number and 9, divided by 4, is greater than or equal to -2, the number is -17.

629 divided by the number c equals 17 what is c answer fast WILL MARK BRAINLY!!

Answers

Answer:

c=37

Step-by-step explanation:

The answer c is 37.

What is Division?

Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number

Here is is given that,

629 divided by the number c equals 17.

Here 629 is the dividend, c is the divisor and 17 is the quotient.

We have to find the value of the divisor.

Mathematically the given statement can be written as,

629 / c = 17

Multiplying both sides of the equation with c, we get,

629 = 17 c

Dividing both sides by 17,

c = 629 / 17

c = 37

Hence the value of c is 37.
