Find the range of values for which x2 - 6x + 8 < 0

Mathematics
1 answer:
Alex73 [517]3 years ago
5 0

Answer:

Step-by-step explanation:

Factor

x^2-6x+8<0

(x-2)(x-4)<0

For this to be less than zero the factors must have opposite signs.

x>2 and x<4

2<x<4

So x is all real numbers between 2 and 4 or in interval notation

x=(2,4)

Write in slope-intercept form 5x-3y=-9<br><br> step by step explanation too, please.
amm1812

Answer:

y = (5/3)x +3

Step-by-step explanation:

slope intercept form

Y = mx +b form

so we need to solve the given equation for y

1.  5x-3y =-9

2 . 5x -3y +3y = -9 +3y (adding both sides 3y)

3. 5x = -9 +3y

4. 5x +9 = -9 +9 + 3y (adding 9 to bot sides)

5. 5x +9 = 3y

6. (5/3)x + 9/3 = (3y)/3 ( divide both sides by 3 to get y  alone)

so, the final answer will be

y = (5/3)x +3

George said that 6 x 10 to the 3 power is 180. do your Agree of Disagree? if you disagree explain the mistake he made and the co
kvv77 [185]

Answer:

The correct answer is 6000

Step-by-step explanation:

I disagree because 10 to the 3rd power = 1000 x 6 = 6000

The mistake he made was that George multiplied all of the number so, 6 x 10 x 3 = 60 x 3 = 180.

RoseWind [281]

The simplified form of the expression [1/5 (-16-9) + 4² ÷ 8] is -3.

Option A) is the correct answer.

<h3>What is the simplified form of the expression?</h3>

Given the expression;  1/5 (-16-9) + 4² ÷ 8

First we remove the parentheses and perform the operations using the guidelines of BODMAS

1/5 (-16-9) + 4² ÷ 8

1/5 × -25 + 4² ÷ 8

1/5 × -25 + 16 ÷ 8

-25/5 + 16/8

-5 + 2

-3

The simplified form of the expression [1/5 (-16-9) + 4² ÷ 8] is -3.

Option A) is the correct answer.
