Answer:

10x+3y=29

Step-by-step explanation:

Given points:(x1,y1)=(2,3)

                     (x2,y2)=(5,-7)

We know, the equation of line passing through two points is given by,

   y-y1={(y2-y1)/(x2-x1)}*(x-x1)

Hence,y-3={(-7-3)/(5-2)}*(x-2)

       or,y-3=(-10/3)*(x-2)

       or,3y-9= -10x+20

        or,3y+10x=20+9

        or,10x+3y=29 is the required equation.

Answer:

the sum of (2x^2-8x) and (-x^2-2x )

=2x^2-x^2-8x-2x=x^2-10x

x ² - 10 x

Step-by-step explanation:

( 2 x ² - 8 x ) + ( - x² - 2 x )

2 x ² - 8 x - x ² - 2 x

2 x² - x ² - 8 x - 2 x ..(combine like terms)

x ² - 10 x

Answer:

Mary Lou is 14

George is 7

Kate is 6

Step-by-step explanation:

let G = George's age

let 2G = Mary Lou's age

let G-1 = Kate's age

G + 2G + G-1 = 27

4G = 28

G = 7

2G = 14

G-1 = 6

Answer:

Step-by-step explanation:

The function y = 2x^2 + 4x has a parabolic graph that opens up.  

*In factored form we have y = 2x(x + 2); if we set this equal to zero and solve for x, we obtain {-2, 0}, the roots of this function.  

*The axis of symmetry is halfway between these roots:  x = -1.  The y-value of the vertex is the value of the function at x = -1:  f(-1) = 2(-1)^2 + 4(-2) = -6.  Thus, the vertex is (-1, -6).

* The y-intercept is (0, 0), since y = 0 when x = 0.

Graph the points shown and draw a smooth curve through them, remembering that this parabola opens up.

Answer:

5/9

Step-by-step explanation:

There are 9 marbles total (3+4+2). There are 2 green marbles and 3 blue marbles (not red). The total fraction will be 5/9.

Answer:

Step-by-step explanation:

3,-3

Answer:

Step-by-step explanation:

The red sections are sectors of the circle. We need that area. We'll find one then multiply it by 2, since they're both the same.

[tex]A_s=\frac{60}{360}\pi (4)^2\\A_s=\frac{1}{6}\pi (16)\\A_s=8.377[/tex]and now we multiply it by 2 to get the red area:

[tex]A_s=16.754[/tex]

And now the area of the circle:

[tex]A_c=\pi (4)^2\\A_c=16\pi\\A_c=50.265[/tex] and now divide to get the percentage:

[tex]\frac{16.754}{50.265}*100=[/tex] 33.3%

Answer:

Step-by-step explanation:

I'm going to  assume you meant y = ab^x. If this is not correct, leave a comment.

x = 0

y = 7

7 = a * b^0

anything to the zero power is 1

y = a*b^0

y = a*1

7 = a

So far what you have is

y = 7 * b^x

Now let

x = 9

y = 3584  

3584 = 7 * b^9         Divide by 7

3584/7 = b^9

512 = b^9

If you knew how to use logs, that would be the surest way to do this question. However I'm going to make an assumption again and assume that you have not taken those yet.

So the easiest way is to find out what raised to the 9th power will equal 512

Could b = 5?

5^9 = 1 million 9 hundred thousand something. 5 is far too big. Make sure you understand why. 1 million is far greater than 512

So let's try b = 3

3^9 = 19 thousand which is still far too big. 19 thousand something is far larger than 512.

We have just one more number that we can try.

2^9 = 512 and we have it

Answer:

y = 1/2x - 14

Step-by-step explanation:

Parallel lines have the same gradient

So,

gradient for second line = gradient of the first line = 1/2

Also,

the line passes through (-6,-17)

So, we can find the y-intercept by substitution

y = mx + c

-17 = (1/2 * -6) + c

-17 = -3 + c

c = -14

So,

the equation is y = 1/2x - 14

Answer:

Cost of bracelet = $1 and 35 cents

Step-by-step explanation:

Price before tax = $ 1.29

Tax Price = 5% of 1.29

              [tex]=\frac{5}{100} \times 1.29\\\\= 6.45 \times \frac{1}{100} \\\\= 0.0645[/tex]

Therefore price after tax = 1.29 + 0.06245 = 1.3545

Ans : cost of bracelet = $1 and 35 cents

Answer:

25% of 32 is 8

Step-by-step explanation:

[tex]\frac{x}{100} * 32 = 8\\\\x = 25%[/tex]

Therefore, 25% of 32 is 8.

8 is 25% of 32.

A percentage is a number or ratio that can be expressed as a fraction of 100.

We know that, 8/32=1/4

in percentage form, 8 of 32= 1/4×100

                                     =25%

Hence, 8 if 25% of 32.
