What is equation is equivalent to 6(3p-2)=20?

Simora [160]

Answer:

$p=\frac{16}{9}$

Step-by-step explanation:

$6(3p-2)=20$

Distribute the brackets.

$6(3p)+6(-2)=20$

$18p-12=20$

Add $12$ on both sides.

$18p-12+12=20+12$

$18p=20+12$

$18p=32$

Divide $18$ on both sides.

$\frac{18p}{18}=\frac{32}{18}$

$p=\frac{16}{9}$

How do I find the domain of f(x)=5x^2+4. When 0<=x<=2<br><br> #54

Blizzard [7]

if 0 ≤ x ≤ 2

$0^2\leq x^2\leq 2^2$

Multiplied by 5..... $5×0^2 \leq 5x^2\leq 5×2^2$

add 4 ......... $5×0^2+4 \leq 5x^2+4\leq 5×2^2$ +4

so ........ $4\leq 5x^2+4\leq 24$

A carpenter purchased 50 ft of redwood and 80 ft of pine for a total cost of $285. A second purchase, at the same prices, includ

Marizza181 [45]

Hey there!!

Let us take the price of the redwood as ' x ' and pine as ' y '

Then , we take it into an equation. We get,

50x + 80y = 285 -------------- ( 1 )

80x + 50y = 339 -------------- ( 2 )

Now, multiply the first equation with 8 and the second equation with 5

400x + 640y = 2280

400x + 250y = 1695

Now subtract the second equation from the first

390y = 585

y = 585 / 390

y = $1.5

Now substitute this into any equation

50x + ( 80 ) ( 1.5 ) = 285

50x + 120 = 285

50x = 165

x = 165 / 50

x = $3.3

Redwood = $3.3

Pine = $1.5

Hope helps!

What is the slope of a line parallel to the line containing (-6,1) and (3,-2)

timama [110]

Answer:

$m = -\frac{3}{9}$

Step-by-step explanation:

Use the following formula:

slope: $m = (y_{2} - y_{1})/(x_{2} - x_{1})$

Let:

$(x_{1} , y_{1}) = (-6 , 1)\\ (x_{2} , y_ {2}) = (3 , -2)\\$

Plug in the corresponding numbers to the corresponding variables:

$m = \frac{-2 - 1}{3 - (-6)}\\\\m = \frac{-3}{3 + 6}\\\\m = \frac{-3}{9}$

$m = -\frac{3}{9}$ is your answer.
