Answers

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

Mike has a certain amount of money and is given $25.25 more money. Anthony has three times the total that mike has plus $5.48 extra dollars. Their combined total is $261.23. Write an equation and solve it to determine how much each of them has.

Answers

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:

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

Step-by-step explanation:

If the point (x, y) reflected about the x-axis, then its image is (x, -y)To find the image of a point reflected about the x-axis change the sign of its y-coordinateThe rule is R x-axis → (x, -y)

If the point (x, y) reflected about the y-axis, then its image is (-x, y)To find the image of a point reflected about the y-axis change the sign of its x-coordinateThe rule is R y-axis → (-x, y)

→ 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)

1. Calculate the value of x in the following diagram. 53 - Y IN Q 5x 18​

Answers

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

x = 7

7z^2 -38z + 15.
Select the factors of this quadratic expression.

Answers

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.

What is the quadratic expression?

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).

Marshall gave the cashier $100 to pay for 4 new video games. The cashier gave him $4.08 in change. Each video game cost the same amount.

What is the cost in dollars and cents for each video game?
PLZZZZ HELP

Answers

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

D i believe.

Step-by-step explanation:

Hope this helps :)

The equation with the greatest growth factor is d(t) = 400 . 3^t

Correct option is D.

As per the given data:

Equations representing the number of bacteria in four different dishes as a function of time, t in days, are given.

To find out the equation with the greatest growth factor:

Growth Factor = Term whose power is raised to t.

For option (A), Growth Factor = (5/6) = 0.834

For option (B), Growth Factor = (1/50) = 0.02

For option (C), Growth Factor = (5/2) = 2.5

For option (D), Growth Factor = (3) = 3

Hence, the equation with the greatest growth factor is d(t) = 400 . 3^t

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

Write a rational function with an x-intercept at (-9,0), a vertical asymptote at x=3, and a hole located at (1,-5). Then, identify the horizontal asymptote.

Answers

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

B Robert's sister's sales total $18.00. C Robert's sales are represented by x when solving 2.6x=63 . D Robert's sales total $25.20. E Robert's sister's sales are represented by x when solving 3.5x=63 .

Answers

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 .
