Answer:

Step-by-step explanation:

h(x) = x² + 1

k(x) = x - 2

(h - k)(3)

Plug x as 3.

h(3) - k(3)

3² + 1 - 3 - 2

Evaluate.

9 - 4

= 5

Answer:

(-2,1)

Step-by-step explanation:

We want the points where the function is greater than zero

Looking at the function it is between the x intercepts

The x intercepts ares -2 and 1

-2 <x<1 is when y >0

We want interval notation

- 3(1 – n) =-6 - 6n<br> Step by step please if possible

harkovskaia [24]

-3 + 3n = -6 - 6n. Expand the brackets
3n + 6n = -6 + 3. Collect like terms
9n = -3
n = -3/9 = -1/3

Fill in the blanks to explain how to solve 3/5 divided by 1/10.

MrMuchimi

You can use a common denominator and rewrite 3/5 divided by 1/10 as 6/10 divided by 1/10.
Than you can think, “How many ___s are in ___? (Sorry, i don’t know this part)
3/5 divided 1/10 is 6

is (-1/2 x + 6/7) - (7/2 x - 4/7) equivalent to -4 x + 2/7 ? use the properties of operations to justify your answer

LuckyWell [14K]

Answer:

The given equation is NOT justified.

Step-by-step explanation:

Here, the given equation is $(\frac{-1}{2}x + \frac{6}{7} ) - (\frac{7}{2}x - \frac{4}{7} )$ = $-4x + \frac{2}{7}$

Now, here Consider the left hand side and simplifying the left side by operating on the like terms,

⇒ $(\frac{-1}{2}x + \frac{6}{7} ) - (\frac{7}{2}x - \frac{4}{7} )$ = $\frac{-1}{2}x + \frac{6}{7} - \frac{7}{2}x + \frac{4}{7} = (\frac{-1}{2}x -\frac{7}{2}x) + (\frac{6}{7} + \frac{4}{7})$

= $(\frac{-1 - 7}{2}x ) + (\frac{6 + 4}{7} ) = \frac{-8x}{2} + \frac{10}{7} \neq -4x + \frac{2}{7}$

Here, Left side of equation ≠ Right side of the equation

Hence, $(\frac{-1}{2}x + \frac{6}{7} ) - (\frac{7}{2}x - \frac{4}{7} )$ ≠ $-4x + \frac{2}{7}$

Solves the inequality. Write your final answer in interval notation:<br><br> -3(2x+1) > -2(x+6)

3241004551 [841]

-3(2x+1) > -2(x+6)

-6x -3 > -2x - 12

-6x -3+6x > -2x - 12+6x

-3>4x-12

-3+12>4x-12+12

9 > 4x

4x<9

x<4/9

(-∞, 4/9)
