The answer should be -1/2.

As we move from left to right, the graph goes thru (0,5) and (2.5,0).
-5
Thus, the "run" is 2.5 and the "rise" is -5. The slope is then m = ------
2.5

or m = -2 (answer).

I need the answer fore both plsss

Answer: 6i) 6a² - 2ab

6ii) -2b³

6iii) b³ + 7b² - 49b

<u>Step-by-step explanation:</u>

6i) (a + b)(5a - 3b) + (a - 3b)(a - b)

= 5a² - 3ab + 5ab - 3b² + a² - ab - 3ab + 3b²

= 5a² + 2ab - 3b² + a² - 4ab + 3b²

= 6a² - 2ab

6ii) (a - b)(a² + b² + ab) - (a + b)(a² + b² - ab)

= a³ + ab² + a²b - ab² - a²b - b³ - (a³ + ab² - a²b -ab² + a²b + b³)

= a³ - b³ - (a³ + b³)

= a³ - b³ - a³ - b³

= -2b³

6iii) (b² - 49)(b + 7) + 343

= b³ + 7b² - 49b - 343 + 343

= b³ + 7b² - 49b

Which of the following is the correct graph of the solution to the inequality −18 > −5x + 2 ≥ −48?

monitta

Answer:

Option D. A number line with an open circle on 4 with shading to the right and a closed circle on 10 with shading to the left

Step-by-step explanation:

we have

$-18 > -5x+2 \geq -48$

Divide the compound inequality into two inequalities

$-5x+2 \geq -48$ -----> inequality A

$-5x \geq -48-2$

$-5x \geq -50$

Multiply by -1 both sides

$5x \leq 50$

Divide by 5 both sides

$x \leq 10$

The solution of inequality A is the interval ----> (-∞,10]

All real numbers less than or equal to 10

$-18 > -5x+2$ -----> inequality B

$-18-2 > -5x$

$-20 > -5x$

Multiply by -1 both sides

$20 < 5x$

Divide by 5 both sides

$4 < x$

Rewrite

$x > 4$

The solution of the inequality B is the interval ----> (4,∞)

All real numbers greater than 4

The solution of the compound inequality is

(-∞,10] ∩ (4,∞)= (4,10]

All real numbers greater than 4 and less than or equal to 10

A number line with an open circle on 4 with shading to the right and a closed circle on 10 with shading to the left

What are exponents and how do I do them?

GREYUIT [131]

Exponents are actually really simple. They are the little numbers on top of numbers and represents powers, so if it was 2 to the power of 2 you multiply 2*2 since there is 2 2s.(
