Answer:

t =1

Step-by-step explanation:

3t - 18 = 4(-3-3/4t)

Distribute

3t - 18 = -12 -3t

Add 3t to each side

3t -18+3t = -12 -3t+3t

6t -18 =-12

Add 18

6t -18+18 = -12+18

6t = 6

Divide by 6

6t/6 = 6/6

t =1

Answer:

t = 1

Step-by-step explanation:

start by distributing the 4 to whats in the parentheses.

4 (-3 - 3/4t)

-12 - 3t

*helpful tip: if you multiply a fraction by its denominator the product is equal to its numerator

now you have:

3t - 18 = -12 - 3t

add 18 to both sides

3t = 6 - 3t

add 3t to both sides

6t = 6

divide both sides by 6

t = 1

Find a parametrization of the line in which the planes x + y + z = -6 and y + z = -8 intersect.

rewona [7]

Answer:

L(x,y) = (2,-8,0) + (0,-1,1)*t

Step-by-step explanation:

for the planes

x + y + z = -6 and y + z = -8

the intersection can be found subtracting the equation of the planes

x + y + z - ( y + z ) = -6 - (-8)

x= 2

therefore

x=2

z=z

y= -8 - z

using z as parameter t and the point (2,-8,0) as reference point , then

x= 2

y= -8 - t

z= 0 + t

another way of writing it is

L(x,y) = (2,-8,0) + (0,-1,1)*t

Find the distance between each pair of points

algol [13]

Answer

$\sqrt{34}$

Step-by-step explanation

You would use the pythagorean theorem for this problem. The point on the y-axis is 5 away from (0,0). The point on the x-axis is 3 away. You would square these, leading from

5+3 to

25+9= $\sqrt{34}$

Answer is $\sqrt{34}$ .

Natalie and John are both saving coins in jars for a rainy day. Natalie currently has 1 1/8 jars of coins, and John has 9/14 of

aivan3 [116]

Answer:

Natalie will have $1\frac{43}{56}$ jars of coins all together after receiving John's coins.

Step-by-step explanation:

Given that:

Coins Natalie have = $1\frac{1}{8}$ jars of coins

Coins John have = $\frac{9}{14}$ jars of coins

When John will give all his coins to Natalie.

Total coins Natalie have = Her coins + John's coins

Total coins Natalie have = $1\frac{1}{8}+\frac{9}{14}$

Total coins = $\frac{9}{8}+\frac{9}{14}$

Total coins = $\frac{63+36}{56}=\frac{99}{56}$

Total coins = $1\frac{43}{56}$

Hence,

Natalie will have $1\frac{43}{56}$ jars of coins all together after receiving John's coins.
