4(2a + 3) < 3(a - 1)

Answer:

6in

Step-by-step explanation:

Let's organize what we know.

- 5gal/1in

- 30gal tank

Since we need to find the inches of the fish he can have, we can set up a proportion like this:

5/1=30/x

We can cross multiply.

5x=1(30)

Simplify: 1*30=30

5x=30

Now we can isolate the variable.

5x=30

x=6

Answer:

385/27

Step-by-step explanation:

Answer:

Step-by-step explanation:

1:    x^2 + 6x = - 7

2:   x^2 + 6x + (6/2)^2 = -7 + (6/2)^2

2:   x^2 + 6x + 9 = - 7 + 9    This might be a 2

2:   x^2 + 6x + 9 = 2

3:   (x + 3)^2 = 2

4:   √(x + 3)^2 = √2  

5:    x + 3 = +/- √2

6:    x = -3 +/- √2

Answer:

8y

Step-by-step explanation:

=(6)(2x)+(6)(y)+2y+−12x

=12x+6y+2y+−12x

Combine Like Terms:

=12x+6y+2y+−12x

=(12x+−12x)+(6y+2y)

=8y

Answer:

8y

Step-by-step explanation:

6(2x+y) comes first 12x+6y then you take 2y and add it from 6y giving you 8y and that gives you the most simplified answer 12x and -12x cancel each other out

Answer:

Step-by-step explanation:

First Add the scores.

Score Total = 787 + 615 + 550 + 674 + 784+ 773 + 620 + 720 + 704

Score Total = 6227

Now divide by the number of members of the sum.

Number of members = 9

The average score = Total Score / number of members

The average score = 6227 / 9 = 691.9

The average score = 692 which is C

Answer:

3y = -x + 17

Step-by-step explanation:

Equation of a line is in the form:

y = mx + c

where m is slope and c is intercept

Mathematically;

slope m = (y2-y1)/(x2-x1)

= (6-4)/(-1-5) = 2/-6 = -1/3

So the equation is now;

y = -x/3 + c

Multiply through by 3

3y = -x + 3c

To get c substitute the value of a point say (5,4)

x = 5 and y = 4

3(4) = -5 + 3c

12 = -5 + 3c

12+ 5 = 3c

3c = 17

c = 17/3

So the equation is

y = -x/3 + 17/3

and that is

3y = -x + 17

Answer:

There is no values of c that makes it true

Step-by-step explanation:

The roots of the quadratic equation x² – 2x + c = 0 are 0 and –2. Then the value of c is zero.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

For which values of c does the quadratic equation

x² – 2x + c = 0 ...1

The one root is equal to zero and one negative root.

Let negative a be the one root.

x = 0, –a

Then we have factorized the equation,

(x)(x + a) = 0

On solving, we have

x² + ax = 0 ...2

In comparing equation 2 with equation 1, we have

a = –2 and c = 0

Answer:

Step-by-step explanation:

The amount more in interest over the life of the loan which Nellie have to pay is $14814.

Bankruptcy is the procedure by which the people who are unable to pay the debts to creditors, may get relief from some or all the debts.

Nellie has a bankruptcy on her credit report and therefore pays higher interest rates on her current loans.

Nellie took out a car loan for $45,000 payable for 6 years at an interest rate of 15%. Thus, the interest is,

[tex]I=\dfrac{45000\times6\times15}{100}\\I=40500[/tex]

If she had not applied for bankruptcy, she would have been able to take out the loan at a rate of 6%. In this case, the interest paid would be,

[tex]I=\dfrac{45000\times6\times6}{100}\\I=16200[/tex]

The difference between the interest paid would be,

[tex]I=40500-16200\\I=24300[/tex]

Hence, the amount more in interest over the life of the loan which Nellie have to pay is $14814.

steps are in the image.

The equation of the line plotted in the graph with the similar triangles on the coordinate plane is y equal to three-fourths x.

Symbolically, it can be written as,

[tex]y=\dfrac{3}{4}x[/tex]

The equation of the line is the way of representation of a line in the equation form.

The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.

[tex]y=mx+c[/tex]

Here, (m) is the slope of the line and (c) is the y intercept.

The similar triangles on the coordinate plane to determine the equation for the given line. The line and the triangle is graphed in the image attached below.

The line passes from origin point (0,0). The coordinate points on the line say P are (4,3) as shown in the image. Thus, for this the slope of the line can be given as,

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\m=\dfrac{3-0}{4-0}\\m=\dfrac{3}{4}[/tex]

The equation of the line for 3/4 slope is,

[tex]y=\dfrac{3}{4}x[/tex]
