Rewrite y - 3 = -9(x - 1) in standard form.

Answers

Answer 1

Answer:

9x + y = 12

Step-by-step explanation:

Hi there!

We are given the equation y - 3 = -9(x-1) and we want to write it in standard form

The equation is currently in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where [tex](x_1 , y_1)[/tex] is a point and m is the slope. Standard form is ax + by = c, where a, b, and c are free integer coefficients

We can first convert the equation from point-slope form into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We can distribute 9 to every term on the right side:

y - 3 = -9x + 9

Now add 3 to both sides

y = -9x + 12

Now the equation is in slope-intercept form (y=mx+b). To make it standard form, add 9x to both sides, to make the form ax + by = c .

9x + y = 12

Hope this helps!

Step-by-step explanation:

half of 16 is 8, and 2 less is 6. 6 + 16 = 22

fill in the blanks with <,>,= symbols( -3)+(-19)+6...................(-41)-15+9​

Answers

First we will simplify both equations....#1

[tex]( - 3) + ( - 19) + 6 \\ - 3 + ( - 19) + 6 \\ - 3 - 19 + 6 \\ = - 16[/tex]

#2

[tex]( - 41) - 15 + 9 \\ - 41 - 15 + 9 \\ = - 47[/tex]

Now,

[tex] - 16 > - 47[/tex]

How?

When the number is in negative the smaller number is greater than the greater number.

Answer:

(-3)+(-19)+6 [>] (-41)-15+9

Step-by-step explanation:

(-3)+(-19)+6= -16

and

(-41)-15+9= -47

so, -16 is greater than -47

A cashier has a total of 98 bills, made up of fives and fifties. The total value of the money is $2605. How much of each kind does he have?
He has ___ fives and ___ fifties.

Answers

Answer:

Step-by-step explanation:

x= number of fives

y= number of fifties

x+y=98

5x+50y=2605

Solving through elimination...

5x+5y=490

(5x+50y)-(5x+5y)=2605-490

45y=2115

y= 47

x+47=98

x=51

Which means he has 51 fives and 47 fifties

Solve for n: 9^(n-1) = (1/3)^(4n-1) Show your work.

Answers

Answer:

n=1/2 after being simplified

Step-by-step explanation:

Use Division Distributive Property:

9^n-1=1/3^4n-1 then convert both sides to the same base

3^2(n-1) = 3^-(4n-1)

cancel the base of 3 on both sides

2(n-1) = -4n+1

then expand 2n-2=-4n+1

add 2 to both sides 2n=4n+1+2

simplify: -4n+1+2 to -4n+3

2n=-4n+3

add 4n to both sides: 2n+4n=3

simplify: 2n+4n to 6n

6n=3

divide both sides by 6

n=3/6

simplify and n=1/2

On a shopping trip, Gina buys two books priced $4.99 and $12.99. She also buys 2 notebooks, 2 packs of pencils, and 3 composition books. The books are on sale for 10% off the list price and school supplies are 15% off. The store charges 6.5% sales tax.



Item Cost ($)
Notebooks 2.88
Composition Books 0.79
Pencil Packs 1.89


How much total will Gina spend on her shopping trip? Round to the nearest cent.

Answers

Answer:

$28.00

Step-by-step explanation:

$4.99 + $12.99 = $17.98 with 10% of discount =$16.18

$2.88 (2) + $0.79 (3) + 1.89 (2) = $11.91 with 15% of discount = $10.12

$16.18 + $10.12 = $26.30 with 6.5% sales tax = $28.00

fraction in lowest terms 33 1/3

Answers

Answer:

If you are asking for its improper fraction form then it is 100/3

Step-by-step explanation:

33*3 (3 is the denominator) = 99

1/3 + 99/3 = 100/3

You can not divide 100 by 3 (and get a whole number), and therefore it can not be simplified  anymore and is the lowest possible term for fractions.

Ex. 2/4 can be simplified to 1/2 but 3/4 can not be simplified anymore.

Another example:

12 1/4

12*4 = 48

1/4 + 48/4 = 49/44

Write an equation of the parabola in intercept form (3, 4) (4,0) (2,0)
An equation of the parabola is y=?​

Answers

The equation of the parabola is gotten as;

 y = -4x² + 24x - 32

We are given the coordinates of a parabola to be;

(3, 4) ; (4,0) ; (2,0)

The general form of equation of a parabola is given by;

y = ax² + bx + c

Let's plug in the x and y coordinates as given to us from the question.

For coordinate (3, 4), the equation is;

(3²)a + 3b + c = 4

9a + 3b + c = 4  ----(eq 1)

For coordinate (4, 0), the equation is;

(4²)a + 4b + c = 0

16a + 4b + c = 0  ----(eq 2)

For coordinate (2, 0), the equation is;

(2²)a + 2b + c = 0

4a + 2b + c = 0  ----(eq 3)

Solving the 3 equations using an online simultaneous equation solver tool, we have; a = -4; b = 24; c = -32

Plugging these values of a, b and c into the general equation of parabola gives us;

       y = -4x² + 24x - 32

Find the value of x and y.

Answers

Answer:

x=25, y=19

Step-by-step explanation:

130+2x=180

x=25

54+2x+4y=180

y=19

Answer:

x = 25 , y = 19

Step-by-step explanation:

130° and 2x° are adjacent angles on a straight line and sum to 180° , so

130 + 2x = 180 ( subtract 130 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

--------------------------------------------------------------

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

130° is an exterior angle of the triangle , then

54 + 4y = 130 ( subtract 54 from both sides )

4y = 76 ( divide both sides by 4 )

y = 19
