Write an equation in standard form for each parabola.

sdas [7]

Answer:

$x=1/4(y-2)^{2}-1$

Step-by-step explanation:

Use Vertex form: $x=a(y-k)^{2}+h$

Given: vertek (h, k)=(-1, 2)

$x=a(y-2)^2 -1$

A point:(x , y) = (3, 6)

$3 = a (6-2)^{2} -1$

16a=4, a=1/4

The equation is : $x=1/4(y-2)^{2}-1$

In a candy store a $5.00 jar of candy is on a boat 50% of what is the discount? What is the sale price of the jar of candy?

Effectus [21]

STEP 1:
Discount $= Price times discount %

=$5.00 * 50%
=$5.00 * 0.50
=$2.50 discount amount

STEP 2:
Sale price= Original $ - Discount amount

=$5.00 - $2.50
=$2.50 sale price

ANSWER: Discount amount is $2.50 and the sale price is also $2.50.

Hope this helps! :)

4a - 5 + 2a + 9 = 28

BaLLatris [955]

Answer:a=4

Step-by-step explanation:

Simplifying

4a + -5 + 2a + 9 = 28

Reorder the terms:

-5 + 9 + 4a + 2a = 28

Combine like terms: -5 + 9 = 4

4 + 4a + 2a = 28

Combine like terms: 4a + 2a = 6a

4 + 6a = 28

Solving

4 + 6a = 28

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + 6a = 28 + -4

Combine like terms: 4 + -4 = 0

0 + 6a = 28 + -4

6a = 28 + -4

Combine like terms: 28 + -4 = 24

6a = 24

Divide each side by '6'.

a = 4

Simplifying

a = 4

Use the inequality x2−8x+6≤0 and graphing calculator, or another piece of technology, to answer Part A and Part B. Part A: What

Kryger [21]

Answer:

Part A) The zero's of the function are $x=0.84, x=7.16$

Part B) The solution set is the interval $[0.84,7.16]$

Step-by-step explanation:

we have

$x^2-8x+6\le0$

Using a graphing calculator

Part A) What are the zeros of the inequality to the nearest hundredth?

The zero's of the function are the values of x when the values of the function are equal to zero

see the attached figure

The zero's of the function are

$x=0.84, x=7.16$

Part B) What is the solution set for the inequality?

The solution set is the interval $[0.84,7.16]$

All real numbers greater than or equal to 0.84 and less than or equal to 7.16

$0.84\leq x \leq 7.16$
