Step-by-step explanation:

if the value of (a) is negative, then (b) being greater than 1 would make the answer smaller. if (a) is positive, then (b) would have to be greater

Answer:

greater than 1

Step-by-step explanation:

must be greater than 1.

WHY?:

a is possitive = +a

b can't be negative or zero

if b is equal to 0

then a * 0 = 0

0 is lesser than one

Answer:

A balance scale.

Step-by-step explanation:

A device for weighing. It has a balanced beam and two pans. When the pans contain exactly the same mass the beam is in balance. You can place an object in one pan and standard weights in the other to find what the object weighs.

You weren't clear with your question, but I am assuming you want to solve for the variable "x."

-2(x - 6) + 7 = 35

-2x + 12 + 7 = 35; distribute the -2

-2x + 19 = 35

-2x = 16; isolate the x variable (the variable you want to solve)

x = -8; divide by -2 to isolate the x variable

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

1) Distribute

[tex]-2(x-6)+7=35\\-2x+12+7=35[/tex]

2) Add the numbers

[tex]-2x+12+7=35\\-2x+19=35[/tex]

3) Subtract 19 from both sides of the equation

[tex]-2x+19=35\\-2x+19-19=35-19[/tex]

4) Simplify

A. Subtract the numbers

[tex]-2x+19-19=35-19\\-2x=35-19[/tex]

B. Subtract the numbers

[tex]-2x=35-19\\-2x=16[/tex]

5) Divide both sides of the equation by the same term

[tex]-2x=16 \\\frac{-2x}{-2} =\frac{16}{-2}[/tex]

6) Simplify

A. Cancel terms that are in both the numerator and denominator

[tex]\frac{-2x}{-2} =\frac{16}{-2}[/tex]

B. Divide the numbers

[tex]x=-8[/tex]

Answer:

[tex](-5, -5)[/tex]

Step-by-step explanation:

To reflect a point over the y-axis is the same as flipping the sign of the x-value of the point.

So, point L reflect is [tex](-(5)), -5)=\boxed{(-5, -5)}[/tex].

Answer:

First option

Step-by-step explanation:

The sign inadvertently shows you where the line should be pointing because it looks like an arrow. Not to mention it means greater than or equal to, so it would be a closed dot.

Answer:

x = - 20

Step-by-step explanation:

12x = -8(10 - x)

12x = -80 + 8x

12x - 8x = -80

4x = -80

x = -80/4 = -20

Answer:

Harriet's Hair Styles

Step-by-step explanation:

Frank's Furters $6.24 /hr

Harriet's Hair Styles $80 for 12 hours weekly

$80 / 12 hr = $6.66/hr

Babysitting $250 a month for 10 hours after school a week. (Assume 4 weeks is a month.)

$250 / (4 wk * 10 hr/wk) = $250/ 40 hr = $6.25/hr

Answer: Harriet's Hair Styles

Harriet's Hair Styles has the highest hourly pay at $6.67 per hour.

To determine which job has the highest hourly pay, we need to calculate the hourly wage for each job based on the information provided.

Frank's Furters: $6.24 per hour.

Harriet's Hair Styles: $80 for 12 hours weekly.

Babysitting: $250 a month for 10 hours after school a week.

Let's calculate the hourly wage for each job:

Frank's Furters: $6.24 per hour.

Harriet's Hair Styles: $80 for 12 hours weekly

= $80 / 12 hours

= $6.67 per hour.

Babysitting: $250 a month for 10 hours after school a week

= $250 / (4 weeks x 10 hours)

= $6.25 per hour.

Hence, Harriet's Hair Styles has the highest hourly pay at $6.67 per hour.

Answer:

Step-by-step explanation:

1.1     Solve   d-2r  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  d-2r  = 0 and calculate its properties

Answer:

0.48 of a mile in 1 minute

Step-by-step explanation:

If Amare runs 1.10 miles in 2.3 minutes, you need to find how much he runs in 1 minute. 2.3 divided by what = 1? 2.3. Divide 1.10 by 2.3 to get 0.47826. You can round this to .48 or even .5, depending on the question. So, Amare runs .48 of a mile in 1 minute.

Answer:

There are only 5 zeros because the 10 to the power of 6 is being multiplied with a decimal.

Step-by-step explanation:

10 to the power of 6 is 1000000

1000000 x 3.5

3500000

the decimal point "takes" a 0 because it is in the tenth place. If it was the hundredths it would take 2 and etc.

Using simple interest, it is found that she has to pay $24,300 more in interest.

The amount of money after t years, in simple interest, is given by:

[tex]A(t) = P(1 + kt)[/tex]

In which:

In this problem:

The amount with 15% interest is:

Here, [tex]k = 0.15[/tex]

[tex]A(6) = 45000[1 + 0.15(6)] = 85,500[/tex]

The amount with 6% interest is:

Here [tex]k = 0.06[/tex].

[tex]A(6) = 45000[1 + 0.06(6)] = 61,200[/tex]

The difference is:

85,500 - 61,200 = 24,300

She has to pay $24,300 more in interest.

Answer:

I cracked the code on my journey to find the correct answer to this problem

The answer is D or $14,814.00

Step-by-step explanation:

This is more than simple interest, this is something to do with amortization

this is a monthly payment calculator for a car loan

[tex]A=p\cdot\frac{\left(r\left(r+1\right)^{n}\right)}{\left(\left(1+r\right)^{n}-1\right)}\\[/tex]

This isn't exactly what we are looking for since we aren't looking for monthly payments but this can still help.

So our variables are [tex]p=45,000[/tex], where p is for principle

r is the loan rate in monthly terms or divide the interest by 12 which is [tex]r=0.0125[/tex] for when 15% is interest and [tex]r=0.0005[/tex] when 6% is interest.

and n is years times 12 or monthly periods involved so [tex]n=72[/tex]

so our equation is [tex]45000\cdot\frac{\left(0.00125\left(0.00125+1\right)^{72}\right)}{\left(\left(1+0.00125\right)^{72}-1\right)}[/tex]

which is equal to 951.53

This number is our monthly payment

so for the full cost is [tex]951.53*12*6[/tex]

that equals 68510.16

now for when interest is equal to 6%

[tex]45000\cdot\frac{\left(0.0005\left(0.0005+1\right)^{72}\right)}{\left(\left(1+0.0005\right)^{72}-1\right)}[/tex]

this is equal to [tex]745.78*12*6[/tex]

so for the full cost is

so the extra interest is equal to the larger number minus the smaller one

[tex]68510.16-53696.16[/tex]

which equals

14,814.00 exactly
