What is the vertex of the quadratic function y=-(x-3)^2+4

Answer:

AB = 5/4 y - 1  = 5/4 (12/13) -1 = 2/13

AC= 7/3 y - 2 = 7/3 (12/13) -2 = 2/13

Step-by-step explanation:

Because it is a equilateral triangle, it means all sides have the same length.

AB = AC

5/4 y - 1 = 7/3 y - 2

5/4 y - 7/3 y = -2 +1

-13/12 y = -1

y = 12/13

input y to the equation.

AB = 5/4 y - 1  = 5/4 (12/13) -1 = 2/13

AC= 7/3 y - 2 = 7/3 (12/13) -2 = 2/13

Answer:

1. x=1

2. x=7

Step-by-step explanation:

1. -8(1+4x)+7x=-25-8x

-8-32x+7x=-25-8x

8x-32x+7x=-25+8

-17x=-25+8

-17x=-17

[tex]\frac{-17x}{-17} =\frac{-17}{-17} \\x=1[/tex]

2. -5+6(x-7)=-40+5x

-5+6x-42=-40+5x

-47+6x=-40+5x

x=47-40

x=7

Answer:

x=1

Step-by-step explanation:

Answer:

x=1

Step-by-step explanation:

4x+8=9x+3

4x+8-8=9x+3-8    

4x=9x-5

4x-9x=9x-5-9x

-5x=-5

divide both sides by -5

x=1

Answer:

He can buy 8 bags of chips.

Step-by-step explanation:

first create a equation:

drink's cost + bag of chip's cost(number of chips) = total

2.9 + 1.85x = 17.7

17.7 is the total, 2.9 is the cost of the drink, 1.85 is the cost of a bag of chips, and x is the number of chips.

Solve for x:

2.9 + 1.85x = 17.7

-2.9              -2.9

         1.85x = 14.8

          1.85    1.85

               x = 8

Check:

12.9 + 1.85(8) = 17.7

12.9 + 14.8     = 17.7

              17.7 = 17.7

Answer:

= 6 over 23 (or = 6/23

Step-by-step explanation:

Convert mixed numbers to improper fractions 3 5/6 = 23/6

Convert element to fraction

= 1 divide 23/6

Apply the fraction rule: a/b divide c/d = a/b x d/c

= 1 over 1 (or 1/1) divide 23/6

Apply rule a/a = 1

= 1 over 1 (or 1/1) x 6/23

Multiply 1x 6/23 = 6/23

= 1 x 6/23

ANSWER 6/23

Answer:

$26.25

Step-by-step explanation:

I multiply each fee with the number of cards it goes along with, then I added it up all together which is 315. To get the monthly fee I divide 315 by 12 to get the answer.

45(2)+35(3)+30(4)

90+105+120 = 315

315/12 = 26.25

Answer:

x = -3

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do t one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

Isolate the x. First, add 9 and subtract 4x from both sides:

6x (-4x) - 9 (+9) = 4x (-4x) - 15 (+9)

6x - 4x = -15 + 9

Combine like terms:

6x - 4x = -15 + 9

2x = -6

Next, divide 2 from both sides of the equation:

(2x)/2 = (-6)/2

x = -6/2

x = -3

x = -3 is your answer.

~

Important things to note:

- PEMDAS is the order of operation, and equals Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction.

- If there is an equal sign and the same variable on both sides, you are trying to isolate that variable.

- Remember to follow the division rule. If you are dividing two negative numbers, your answer will be positive. If you are multiplying two negative numbers, your answer will be positive. If you are dividing or multiplying one positive and one negative number, your answer will be negative.

The midpoint is ( 1,4)

Step-by-step explanation:

To find the x coordinate of the midpoint add the x coordinates of the endpoint and divide by 2

( 7+-5)/2 = 2/2 =1

To find the y coordinate of the midpoint add the y coordinates of the endpoint and divide by 2

( 3+5)/2 = 8/2 =4
