Bess [88]2 years ago

7 0

Answer:

x=0

Step-by-step explanation:

-8x + 2(4x + 2) = 4

Use distributive property to get rid of the parentheses

-8x + 8x + 4 = 4

Add the like terms.

x + 4 = 4

Subtract both sides by four.

x = 0

7p − p = 18 2) −5n − 4n = −9

Savatey [412]

Answer:

<h3> $\boxed{ \bold{ \sf{ \boxed{ p = 3}}}}$ </h3>

$\boxed{ \bold{ \sf{ \boxed{n = 1}}}}$

Step-by-step explanation:

1. $\sf{7p - p = 18}$

Collect like terms

⇒ $\sf{6p = 18}$

Divide both sides of the equation by 6

⇒ $\sf{ \frac{6p}{6} = \frac{18}{6} }$

Calculate

⇒ $\sf{p = 3}$

2. $\sf{ - 5n - 4n = - 9}$

Collect like terms

⇒ $\sf{ - 9n = - 9}$

Divide both sides of the equation by -9

⇒ $\sf{ \frac{ - 9n}{ - 9} = \frac{ - 9}{ - 9} }$

Calculate

⇒ $\sf{n = 1}$

Hope I helped!

How do i graph <br> x–3y=–9<br> 2x–3y=–6

Katen [24]

Right now the equations are in standard form, which is ax+by=c. You need to put them in the form y=x and then divide the equations by 3 since y itself is being multiplied by 3. And then graph them as you normally would

Hope this helps!

What is the area of rectangle ABCD with vertices A -3,0 B 3,2 C 4,-1 D -2,-3

Naddik [55]

For this, simply find the width and length by finding the distance between the two points. This can be done using the equation $\sqrt{(y2 - y1)^2 + (x2 - x1)^2}$

AB(length): $\sqrt{(0 - 2)^2 + (3 - (-3))^2}$

--> $\sqrt{-2^2 + 6^2}$

---> $\sqrt{40}$ = 6.32

BC(width): $\sqrt{(2 - (-1))^2 + (4 - 3)^2$

--> $\sqrt{(2 + 1)^2 + 1^2}$

---> $\sqrt{27 + 1}$

----> $\sqrt{28}$ = 5.29 ≈ 5.3

Area = 33.496 ≈ 33.5

Evaluate each expression<br> 6! =<br> 3! • 2=<br> 31

Airida [17]

<h2><u>N-FACTORIAL!</u></h2>

<h3> $\mathbb{ \color{brown} \: PROBLEM } \: \: \bold{{ \color{brown}{1}}} :$ </h3>

$\mathcal{SOLUTION: }$

$\: \bold{ \red{6!}= 6×5×4×3×2×1= \boxed{ \bold{ \blue{720}}}}$

Therefore, <u>the value of 6! is 720</u>.

━┈─────────────────────┈━

<h3> $\mathbb{ \color{brown} \: PROBLEM } \: \: \bold{{ \color{brown}{2}}} :$ </h3>

$\mathcal{SOLUTION: }$

$\bold{3! \cdot 2! }\implies \bold{(3×2×1) \cdot( 2×1 )}$

$\: \: \: \: \: \: \: \: \: \: \: \: \implies \: \bold{ 6 \times 2} = \boxed{ \bold{ \blue{12}}}$

Therefore, <u>the value of the given expression is 12.</u>

━┈─────────────────────┈━

<h3><u>EXPLANATION</u><u>:</u></h3>

The mathematical symbol n! is read as "n factorial". The exclamation point "!" is read as factorial. And please remember or take note that 0! is equal to 1, and 1! is also equal to 1.
