Mathematics
1 answer:
elixir [45]3 years ago
5 0

Answer:

y\geq 3x-1 ; x+3y\leq 6

Step-by-step explanation:

we know that

step 1

Find the inequality of the solid line x+3y=6

The solution is the shaded area below the solid line

therefore

The equation of the inequality is

x+3y\leq 6

step 2

Find the inequality of the solid line y=3x-1

The solution is the shaded area above the solid line

therefore

The equation of the inequality is

y\geq 3x-1

therefore

The system of linear inequalities is

y\geq 3x-1 ; x+3y\leq 6

I need the answer and the work! <br> you have to find n.
zloy xaker [14]

Tell you what I'll do:  I'll show you the work, for two of them.
Then, knowing how to do it, you'll find the answers.
Deal ?

#1). n + (-13) = -12

Remove the parentheses
on the left side:                     n - 13 = -12

Add  13  to each side:           n        =    1

================================

#3).                        -15 + n  =  3

Add  15  to each side:     n  =  18


OK.  Look those over, understand how they're done, then TAKE IT !

Multiple the polynomials (3x^2+4x+4) (2x-4)
natali 33 [55]

Answer:

6x³ - 4x² - 8x - 16

Step-by-step explanation:

Step 1: Distribute the 2x

6x³ + 8x² + 8x

Step 2: Distribute the -4

-12x² - 16x - 16

Step 3: Combine the 2 distributions

6x³ + 8x² + 8x - 12x² - 16x - 16

Step 4: Combine like terms

6x³

8x² - 12x² = -4x²

8x - 16x = -8x

-16

Step 5: Rewrite

6x³ - 4x² - 8x - 16

What is -11 2/3 x (-4 1/5) = ?
adelina 88 [10]

Answer:

49

Step-by-step explanation:

-11 2/3 x (-4 1/5) =

negative times negative = positive

Change the mixed numerals into fractions.

= 35/3 × 21/5

Multiply the numerators together. Multiply the denominators together.

= (35 × 21)/(3 × 5)

Simplify.

= (7 × 5 × 7 × 3)/(3 × 5)

Divide the numerator and denominator by 3 and by 5.

= 7 × 7

= 49
