Answer:

The coordinates of point P along AB is (1,6.5)

Step-by-step explanation:

We shall use the internal division formula to split AB in the ratio 1 to 3

Mathematically, that would be;

(x,y) = (nx1 + mx2)/m + n , (ny2 + my1)/m + n

m = 1 , n = 3

(x1,y1)= (-1,2)

(x2,y2) = (7,8)

(x,y) = (3(-1) + 1(7)/1+3 , (3(8) + 1(2)/1+3

(x,y) = (-3 + 7)/4, (24 + 2)/4

(x,y) = 4/4 , 26/4

(x,y) = (1, 6.5)

Answer: [tex]2x^2-7x=72[/tex] , where  x= width of the rectangle ( in inches).

Step-by-step explanation:

Let x= width of the rectangle ( in inches).

Then its length =  2x-7 ( in inches).

Area of rectangle = Length × width

= (2x-7) × (x)

= 2x × x -7 ×x

= 2x²-7x

The area of the rectangle is 72 square inches.

[tex]\Rightarrow\ 2x^2-7x=72[/tex]

Hence, the equation that represents the given situation :

[tex]2x^2-7x=72[/tex]

Answer:

54

Step-by-step explanation:

You can use the short cut 0.6 * 90 ( * is another symbol for the multiplication symbol) this works differently for different numbers. If your percent is one digit, like 3%, you want to change it into the decimal 0.03. The reason why you multiply them together is because “of” is another word for multiply in math terminology.

Answer:

64.3 Per hour

Step-by-step explanation:

If you divide 321.5 miles by 5 you get 64.3 per hour and to check you could times 64.3 by 5 to get 321.5

321.5 / 5 = 64.3

64.3 x 5 = 321.5

Answer: 9[tex]\pi[/tex]

Step-by-step explanation:

Sorry the pi sign looks weird. The formula for area of a circle is [tex]a=\pi r^2[/tex], so we have to substitute the radius with 3. The square of 3 is 9, so the answer is 9pi.

Answer:

The answer is: 9x^2 - 12x + 4

Step-by-step explanation:

Perfect square formula: (a - b)^2 = a^2 - 2ab + b^2 ; a = 3x, b = 2

(3x)^2 - 2 * 3x * 2 + 2^2

Simplify:

9x^2 - 12x + 4

The expanded and simplified form of (3x-2)^2 is 9x^2 - 12x + 4.

To expand and simplify (3x-2)^2, we can use the FOIL method. FOIL stands for First, Outer, Inner, Last and is a systematic way to multiply two binomials.

First, let's square the first term:

(3x)² = 9x²

Next, we multiply the outer terms:

(3x)(-2) = -6x

Then, we multiply the inner terms:

(-2)(3x) = -6x

Finally, we square the last term:

(-2)² = 4

Now, let's combine all the terms:

9x² - 6x - 6x + 4

Combining like terms, we have:

9x² - 12x + 4

So, the expanded and simplified form of (3x-2)² is 9x² - 12x + 4.

Answer:

Step-by-step explanation:

Things to remember,

1). Any point on the graph of a function is represented by [x, f(x)].

2). x-coordinates are the input values on x-axis and f(x) is the output value of the function on y-axis.

A). For x = 2, value of f(2) will be,

    f(2) = 4

B). For x = 5, value of f(5) will be,

    f(5) = 7

C). Since, 4 < 7

   Therefore, f(2) is less than f(5).

Answer:

2

Step-by-step explanation:

Given the function

f(x) = x^3 − x + 4 in the interval [1,2]

We are to find the value of x for which f(x) = 7

Substitute f(x) = 7 into the expression as shown!

f(x) = x^3 − x + 4

7 = x^3 − x + 4

x^3 − x + 4 -7 = 0

x^3 − x - 3= 0

x^3 -x = 3

x(x²-1) = 3

x²-1 = 3 and x = 3

x² = 3+1

x² = 4

x = ±√4

x = ±2

Since x lies within the interval, [1,2] hence the value of x is 2

Answer:

just substitute the X's

Answer:

3/5 cup

Step-by-step explanation:

I start by changing the initial fraction of 3/4 into its decimal form of .75 so that it's easier to divide. I then divide it by 5 to find how much carbonated water you should use for a single cup of juice, which is .15 cups. Then, I multiply .15 times 4, which comes out to be .6, or 3/5.

Answer:

3/4 cups of carbonated water is needed by Andy to prepare 5 cups of fruit juice that means that he uses

(3/4)/5 = 3/20 cups of carbon. water for one cup of fruit juice for 4 cups he has to use (3/20)4=12/20

or 3/5 cups of carbonated water or in decimal form 0.6 cups
