Answer:

[tex]y=8x-25[/tex]

Step-by-step explanation:

The first thing to do is to find the slope. The slope is the difference in Y divided by the difference in x, or:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here (3, -1) is going to be (x1, y1) and (4, 7) will be (x2, y2):

[tex]m=\frac{7--1}{4-3}=\frac{8}{1}=8[/tex]

The slope is 8. Now, you can plug that into the formula. To find the y-intercept, plug in any point on the line and solve for b:

[tex]y=mx+b\\-1=8(3)+b\\-1=24+b\\b=-25[/tex]

Now we have both the slope and the y-intercept so you can write the equation for the line:

[tex]y=8x-25[/tex]

You can test that either by checking y for some value of x, or by graphing.

Based on the information how long did it take to reach $10650 is 7years.

Given:

Principal=$7,500

Rate=6%

Amount=$10650

Time=?

Simple Interest(SI)=A-P

=$10650-$7500

=$3150

Time=(100×SI)/(p×r)

T=(100×3150)/(7500×6)

T=315,000/45,000

T=7 years

Inconclusion how long did it take to reach $10650 is 7years.

The period it took the $7,500 investment to reach a future value of $10,650 at a compounding interest rate of 6% is 6 years.

The future value refers to the compounded value of present cash flows in the future, using an interest rate.

The future value can be determined using the future value table or formula.

We can also determine the future value using an online finance calculator, which also enables us to determine the period required to get a stated future value.

PV (Present Value) = $7,500

I/Y (Interest per year) = 6%

PMT (Periodic Payment) = $0

FV (Future Value) = $10,650

Results:

N (# of periods) = 6 years

Total Interest = $3,142.17

Thus, the period it took the $7,500 investment to reach a future value of $10,650 at a compounding interest rate of 6% is 6 years.

Answer:

-13 or 13

Step-by-step explanation:

Since we are looking for the square root of 169, we realize that 13 multiplied by itself equals 169. Negative 13 does the same, so it is the answer.

Step-by-step explanation:

Given that (x+1,5) = (4,x+2y)

⇛ x+1 = 4 and 5 = x+2y

⇛ x = 4-1

⇛ x = 3

now

5 = x+2y

⇛ 5 = 3+2y

⇛ 5-3 = 2y

⇛ 2 = 2y

⇛ 2y = 2

⇛ y = 2/2

⇛ y = 1

Therefore, x = 2 and y = 1

Step-by-step explanation:

A board foot is 1 inch thick by 1 ft by 1 ft

(3) 1 x 6  8'  are already 1 inch thick ½ ft wide and 8 ft long

  3 x 1 x (6/12) x 8 = 12 board ft.

(6) 2" x 10" x 12'  are 2 thick x 10/12 ft wide by 12 ft long

  6 x 2 x (10/12) x 12 = 120 board ft.

Answer:

1 1/15

Step-by-step explanation:

64 minutes is the same thing as 64/60 minutes.

64 goes into 60 once. 64-60=4, so that would be your numerator. You would keep the denominator as 60, since it's still out of 60.

If you put those numbers together your fraction would be

1 and 4/60, if you want to simplify, 60/4=15, so 1 and 1/15 would be your fraction.

Answer:

So lets isolate y

we have

-2x+3y=9

2/3x +2y=0

Im gonna do the first equation

so -2x + 3y = 9

Add 2x on both sides

3y= 9+ 2x

Now divide by 3 to isolate y

y= 3+ 2/3x

Now we can subsitute y into any eqaution (I’m gonna do the second one) to solve.

2/3x+ 2(3+ 2/3x)= 0

Solve:

2/3x+ 6 + 4/3x = 0

6/3x +6= 0

2x+6=0

2x= -4

x= -2

Now we can subsitute this for any equation.

so I’m gonna do the first equation

-2(-2)+3y=9

4+3y=9

3y= 5

y= 5/3

y= 1 2/3

Final answer:

x=-2

y= 1 2/3

Answer:

x² + 10x + 25

Step-by-step explanation:

(x + 5)(x + 5)

using FOIL method

First x•x = x²

Outside x•5 = 5x

Inside 5•x = 5x

Last  5•5 = 25

add like terms together.

Answer:

x^2 + 25 + 10x

= x^2 + 10x + 25

Step-by-step explanation:

( x + 5 )^2

Formula : -

( a + b )^2 = a^2 + b^2 + 2ab

Here,

a = x

b = 5

( x + 5 )^2

= x^2 + 5^2 + 2 ( x ) ( 5 )

= x^2 + 25 + 10x

Answer:

D. 0.343

Step-by-step explanation:

You can see the first three options as 0.340 so if you substract this number with 0.343 the remainder is positive 3.

This strategy also can be applied to the number 0.3409 but in this occasion the result is different:

[tex]0.343 - 0.3409 = 2.1\times 10^{-3}[/tex]

That is small number but still is positive that's meaning that between 0.343 and 0.3409 the greatest value is 0.343 .

Answer:

y = 8/5x + (-4) or y = 8/5x -4

Step-by-step explanation:

Slope-intercept form is written like this:

            y = mx + b

The variable m, represents slope and b, represents the y-intercept.

To find slope, you have to find the rise/run or in other words, change of y over change of x.

From the look of the line, the slope has to be positive because the line is going up.

To go from the bottom point to the top, we have to go up 8 points and go to the right 5 points. Thus the slope is 8/5.

Now for the y-intercept. This part is easy. Just ask yourself this...

"Which of the two points is on the y-axis?"

In this case, it is the bottom point which is -4.

So your equation should look like this:

y = 8/5x + (-4)

   or y = 8/5x - 4 because when you have a plus sign and a minus sign, the result is negative.

Step-by-step explanation:

Given the addition of two unlike fractions, [tex]\mathsf{\frac{2}{5} \: +\:\frac{2}{7} }[/tex] :

We could only add those two fractions if they have the same denominator.

In order to do so, we must determine their least common denominator (LCD), which happens to be 35.  

Next, perform the following mathematical operations:

[tex](\mathsf{\frac{2}{5} \:\times\frac{7}{7}}) + (\mathsf{\frac{2}{7} \:\times\frac{5}{5}})[/tex]  =  [tex]\mathsf{\frac{14}{35} \:+ \:\frac{10}{35}}[/tex]  =  [tex]\mathsf{\: \frac{24}{35} }[/tex]

Answer:

  C. quadratic function; quadratic term: 6x^2; linear term: x; constant term: −12

Step-by-step explanation:

A function is "quadratic" when the degree (exponent) of the highest-degree term is 2. The "quadratic" term is the one with degree 2.

The "linear" term is the one that has degree 1.

The "constant" term has no variable.

In the quadratic function ...

  f(x) = 6x^2 +x -12

the quadratic term is 6x^2

the linear term is x

the constant is -12

Answer:  The answer is either letter B or letter C

C. quadratic function; quadratic term: 6x2; linear term: x; constant term: −12

Step-by-step explanation:

Find the degree of the function to determine if linear.  f ( x ) =  6 x 2 + x − 12  is not a linear function

Nothing further can be done with this topic. Please check the expression entered or try another topic.  f ( x ) =  6 x 2 + x − 12

Answer:

Step-by-step explanation:

14/3 = 4⅔

343/32 = 10 ²³/₃₂

26/3 = 8⅔

It's pretty much simple. Since we can factor a polynomial by its zeros, lets write one of degree nine :

X(X-1)(X-2)(X-3)(X-4)(X-5)(X+1)(X+2)(X+3)= X^9-9X^8+6X^7+126X^6-231X^5-441X^4+944X^3+324X^2-720X

This polynomial is of degree 9 and has exactly 5 strictly positive zeros : 1, 2, 3, 4, 5

And it has 3 negative zeros : - 1, -1, - 3

And it has 0 as a zero too.

There is also this one :

(X-1)(X-2)(X-3)(X-4)(X²+1)(X+1)(X+2)(X+3) = X^9-4X^8-13X^7+52X^6+35X^5-140X^4+13X^3-52X^2-36X+144

It has 4 positive zeros : 1, 2, 3, 4.

It has complex zeros : i and - i

3 negative zeros : - 1, - 2 , - 3
