HELP ME DO THIS PLZZZZ

Mathematics
1 answer:
andrezito [222]3 years ago
4 0

Answer:

Step-by-step explanation:

y = -x^2+4x-6x +24

y = -x^2 -2x + 24

Vertex (x) = 2/-2 = -1

Vertex (y) =  -100/ -4 = 25

Vertex (-1, 25)

axis of symmetry: x= -1

-x^2 -2x + 24 = 0

Δ/4 = 1+24 = 25

x1 = (1 + 5)/-1 = -6

x2 = (1-5)/-1 = 4

left x intercept = (-6,0)

right x intercept = (4,0)

The DOMAIN is the set of all numbers

The range is y less than or equal to 25

Which expression is equivalent to (7x – 5) – (3x - 2)
Nastasia [14]

Answer:

D

Step-by-step explanation:

We have the expression

(7x-5)-(3x-2)

First we need to distribute the negative throughout the parenthesis. Then we can combine like terms in order to simplify this expression

(7x-5)-(3x-2)\\\\7x-5-3x+2\\\\4x-3

This answer matches D.

A seagull was flying about sea level looking to catch a fish below sea level. The elevation above sea level was 125 1/2 feet. He
frez [133]

Answer:

The seagull's position halfway is 85.5 feet.

Step-by-step explanation:

The seagull is at 125 1/2 feet above the sea level.

The fish is at 45 1/2 feet below the sea level.

The distance between the seagull and fish = seagull's distance above the sea level + fish's distance below the sea level

                                                  = 125 1/2 + 45 1/2

                                                  = \frac{251}{2} + \frac{91}{2}

                                                  = \frac{342}{2}

                                                  = 171

The distance between the seagull and fish is 171 feet.

Since the seagull stops halfway, then;

seagull's position = \frac{171}{2}

                             = 85.5

The seagull's position halfway is 85.5 feet.

Solve this and help me plsss​
alexandr402 [8]

Answer:

x = 2

Step-by-step explanation:

(x² logₓ27) log₉x = x + 4

Use change of base formula.

x² (log 27 / log x) (log x / log 9) = x + 4

Simplify.

x² (log 27 / log 9) = x + 4

x² (log 3³ / log 3²) = x + 4

x² (3 log 3 / (2 log 3)) = x + 4

x² (3 / 2) = x + 4

3x² = 2x + 8

3x² − 2x − 8 = 0

(x − 2) (3x + 4) = 0

x = 2 or -4/3

Since x > 0, x = 2.
