Answer:

slope(m)=4 and

y-intercept(c)=-5/2

Step-by-step explanation:

here,8x-2y=5

reducing it into slop intercept form we get,

2y=8x-5

or,y=8/2x+(-5/2)

or,y=4x+(-5/2)

comparing it with y=mx+c we get,

slope(m)=4 and

y-intercept (c)=-5/2

Answer and Step-by-step explanation:

We are told that the circumference is 20, and we are asked to find the area.

The equation for circumference is:

C = 2[tex]\pi[/tex]r

We can plug in 20 and solve for r.

20 = 2[tex]\pi[/tex]r

Divide by 2 on both sides.

10 = [tex]\pi[/tex]r

Now divide by [tex]\pi[/tex] on both sides.

[tex]\frac{10}{\pi }[/tex] = r

Now, we can plug this into the area equation:

A = [tex]\pi[/tex][tex]r^{2}[/tex]

A = [tex]\pi[/tex][tex](\frac{10}{\pi } )^{2}[/tex]

A = [tex]\pi[/tex][tex]\frac{100}{\pi ^{2} }[/tex]

A = [tex]\frac{100\pi }{\pi ^{2} }[/tex]

A = [tex]\frac{100}{\pi }[/tex]

Now, we put this into the calculator to solve.

We get:

31.830988618379067153776752674503

We are then told to round to the nearest whole number.

8 is greater than 5, so we round up.

Answer:

Mike has =$63.94

Anthony = $197.3

Step-by-step explanation:

Step one:

let the certain amount that Mike has be x

so

in all Mike has = (x+25.25)

Anthony has

3(x+25.25)+5.48

we are told that the total amount for both Mike and Anthony is

$261.23

so

(x+25.25)+3(x+25.25)+5.48=261.23

open bracket

x+25.25+3x+75.75+5.48=261.23

collect like terms

x+3x+25.25+75.75+5.48=261.23

4x+106.48=261.23

4x=261.23-106.48

4x=154.75

divide both sides by 4

x=154.75/4

x=38.69

Hence,in all

Mike has = (38.69+25.25)

Mike has =$63.94

Anthony has

=3(38.69+25.25)+5.48

=3(63.94)+5.48

=191.82+5.48

=$197.3

Answer:

Cost of one cheap golf ball is $0.75 and one expensive golf ball is $2.00

Step-by-step explanation:

Let,

x be the price of one cheap golf ball

y be the price of one expensive golf ball

According to given statement;

6x+4y=12.50     Eqn 1

4x+3y=9.00      Eqn 2

Multiplying Eqn 1 by 4

4(6x+4y=12.50)

24x+16y=50.00    Eqn 3

Multiplying Eqn 2 by 6

6(4x+3y=9.00)

24x+18y=54.00     Eqn 4

Subtracting Eqn 3 from Eqn 4

(24x+18y)-(24x+16y)=54.00-50.00

24x+18y-24x-16y=4.00

2y=4.00

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{4.00}{2}\\y=2.00[/tex]

Putting y=2.00 in Eqn 1

6x+4(2.00)=12.50

6x+8.00=12.50

6x=12.50-8.00

6x=4.50

Dividing both sides by 6

[tex]\frac{6x}{6}=\frac{4.50}{6}\\x=0.75[/tex]

Hence,

Cost of one cheap golf ball is $0.75 and one expensive golf ball is $2.00

Answer:

The coordinates of point P are (1, -1)

Step-by-step explanation:

→ Assume that the coordinates of point P are (x, y)

∵ The coordinates of point P are (x, y)

∵ The rule of the reflection is R y-axis (P)

∴ Its image = (-x, y)

∵ The image = (-1, -1)

→ Equate the two images

∴ (-x, y) = (-1, -1)

∴ -x = -1

→ Divide both sides by -1

∴ x = 1

∵ y = -1

∴ The coordinates of point P are (1, -1)

Answer:

I would say it's $23.98

Step-by-step explanation:

If you do 100-4.08, you get 95.92 and since there's 4 video games, divide 95.92 by 4 and you get 23.98

Answer:

$23.98 or 2398 cents

Step-by-step explanation:

If the cashier gave $4.08 back, that means that he spent 100-4.08 on the 4 games.

$100 = 4 games + $4.08

4 games  = $95.92

$95.92/4 = $23.98

Answer:

B. Robert's sister's sales total $18.00.

E. Robert's sister's sales are represented by x when solving 3.5x = 63 .

Step-by-step explanation:

Let

Robert sister's sales = x

Robert sales = 2.5 * x

= 2.5x

Total sales = Robert sister's sales + Robert sales

63 = x + 2.5x

63 = 3.5x

Divide both sides by 3.5

x = 63 ÷ 3.5

= 18

x = $18.00

Robert sales = 2.5x

= 2.5(18)

= $45.00

A. Robert's sales are represented by x when solving 3.5x=63 .

No

B. Robert's sister's sales total $18.00.

Yes

C. Robert's sales are represented by x when solving 2.6x=63 .

Answer:

7z - 3 and z - 5

Step-by-step explanation:

The factors of the given quadratic expression is (z-5((7z-5).

The given quadratic expression is 7z² -38z + 15.

An expression of the form ax² + bx + c, where a ≠ 0 is called a quadratic expression. In other words, any expression with the variables of the highest exponent or the expression's degree as 2 is a quadratic expression.

The given quadratic expression 7z² -38z + 15 can be solved as follows:

Using spitting middle term

7z² -35z-3z + 15

= 7z(z-5)-3(x-5)

= (z-5((7z-5)

Therefore, the factors of the given quadratic expression is (z-5((7z-5).

Answer:

x = 7

Step-by-step explanation:

QY = 5x

YZ = 18

QZ = 53

Thus:

QY + YZ = QZ (segment addition postulate)

5x + 18 = 53

5x = 53 - 18 (subtraction property of equality)

5x = 35

Divide both sides by 5

Answer:

The rational function is [tex]f(x) = \dfrac{x^2 + 8\cdot x - 9}{x^2 - 4 \cdot x + 3}[/tex]

The horizontal asymptote occur at y = 1

Step-by-step explanation:

Given that the function has an x-intercept at (-9, 0), we have;

(x + 9) is a factor of the function

Also, given that the function has a vertical asymptote at x = 3, we have that a factor of the denominator of the function is (x - 3)

With a hole at (1, -5), we have, (x - 1) in both the numerator and the denominator and when x = 1, f(x) = -5

The general form of the function can be presented as follows;

f(x) = ((x + 9)·(x - 1))/((x - 3)(x - 1)) = (x² + 8·x - 9)/(x² - 4·x + 3)

Given that the power of the numerator and the denominator are equal, the horizontal asymptote occur at ratio of the leading coefficient of the numerator and the denominator which from the above equation is 1/1 = 1

The horizontal asymptote occur at y = 1
