Answer:5/5

Step-by-step explanation:

7(x + 9 ) - x

Explanation:

the quantity x plus 9 is written x + 9 , plus meaning add.

times the quantity means multiply the quantity x + 9 multiplied by 7

this is written 7(x + 9 )

finally minus x means subtract x

putting it all 'together' we get 7(x + 9 ) - x

Answer:

The correct answer is C.

Step-by-step explanation:

Giving the following information:

Loan A: 9.265% nominal rate, compounded weekly

Loan B: 9.442% nominal rate, compounded monthly

Loan C: 9.719% nominal rate, compounded quarterly

To calculate the effective annual rate, we need to use the following formula:

Effective annual rate= [(1+i)^n] - 1

Loan A:

i= 0.09265/52= 0.001782

Effective annual rate= [(1.001782^52) - 1]

Effective annual rate= 0.097 = 9.7%

Loan B:

i= 0.09442/12= 0.007868

Effective annual rate= [(1.007868^12) - 1]

Effective annual rate= 0.0986 = 9.86%

Loan C:

i= 0.09719/4= 0.02439

Effective annual rate= [(1.02439^4) - 1]

Effective annual rate= 10.11%

Answer:

No

Step-by-step explanation:

y = 4x + 1 is not a direct variation. Direct variations have the form y = kx. So y = 4x would be a direct variation (k=4), but not y = 4x+1

Answer:

8x + 5

Step-by-step explanation:

You add like terms:

2x + 6x = 8x.

6 + (-1) = 5

Adding them up, you get:

8x + 5

Answer:

a) [tex]x=\frac{y}{m}-\frac{b}{m}[/tex]

b) [tex]m=\frac{y}{x}-\frac{b}{x}[/tex]

Step-by-step explanation:

We are given the equation:

y = mx + b

[tex]y=mx+b\\\\mx+b=y\\\\mx+b-b=y-b\\\\mx=y-b\\\\\frac{mx=y-b}{m}\\\\\boxed {x=\frac{y}{m}-\frac{b}{m}}[/tex]

Answer:

Step-by-step explanation:

Given the polynomial P(x) = x^2-3x-10

To check that the remainder is zero if divided by x - 5, we will first have to equate x - 5 to zero and get x;

x - 5 = 0

x = 5

Then find P(5)

P(5) = 5^2 - 3(5) - 10

P(5) = 25 - 15 - 10

P(5) = 25-25

P(5) = 0

This shows that x - 5 is a factor of the polynomial since P(5) gave us zero according to the factor theorem

Don't answer someone's question with some nonsense and then delete it; especially when I spent over an hour on that one question. I will surely delete my answers after this and still have my 30 points...

don't reap what you sow :)

You can search that up if you don't even know what that means.

Answer:

Step-by-step explanation:

z varies inversely

so z=a/x^2

9=a/(2/3)^2

9=a/(4/9)

9=9a/4

a=4

z=4/x^2

z=4/(5/4)^2

z=4/(25/16)

z=64/25

If z varies inversely as x², it is given by the equation z = 4/x². When x = 5/4, z = 2.56

An equation is an expression that shows the relationship between two or more numbers and variables.

z varies inversely as x². Let k represent the constant of proportionality, hence:

z = k/x²

z = 9 when x = 2/3, hence:

9 = k / (2/3)²

k = 4

z = 4/x²

When x = 5/4:

z = 4 / (5/4)²

z = 2.56

If z varies inversely as x², it is given by the equation z = 4/x². When x = 5/4, z = 2.56

Step-by-step explanation:

Answer:

in order

y = -3x + 5

y = 1/2(x) + 2

y = -x - 3

y = 2/3(x) - 2

Step-by-step explanation:

slope-intercept form is y= mx + b

10. 6x + 2y = 10

2y = -6x + 10, subtract 6x from both sides

y= -3x + 5, divide both sides by 2

11. x + 2y = 4

2y = x + 4, subtract x from both sides

y = 1/2(x) + 2, divide both sides by 2

12. x + y = -3

y = -x - 3, subtract x from both sides

13. -2x + 3y = -6

3y = 2x - 6, add 2x to each side

y = 2/3(x) - 2, divide both sides by 3

Answer:

The decimal is 0.46

Step-by-step explanation:

Given

Less than 0.8

Greater than 0.02

Required

Determine the decimal

Let the decimal be x

Such that:

[tex]x < 0.8[/tex] and [tex]x > 0.02[/tex]

Rewrite as:

[tex]x > 0.02[/tex] and [tex]x < 0.8[/tex]

Rewrite as:

[tex]0.02 < x[/tex] and [tex]x < 0.8[/tex]

This can be merged to give:

[tex]0.02 < x<0.8[/tex]

From the list of given options, only 0.46 fall in this range because:

[tex]0.02 < 0.46<0.8[/tex]

So:

[tex]x = 0.46[/tex]
