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

Step-by-step explanation:

Answer:

(-1,4)

Step-by-step explanation:

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

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 .

No

D. Robert's sales total $25.20.

No

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

Step-by-step explanation:

they meet on (-3,-$4) so just plug the numbers in

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

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

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 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:

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
