Answer:

b=0 would appreciate brainliest

Step-by-step explanation:

Otherwise, no solution for this equation. You cannot isolate the variable a; its solution value can be anything, but you still find b=0.

2a+b=2a

b+2a=2a

b+2a-2a=2a-2a

b+0=0

b=0

1. Which becomes 2(1) + 0 = 2(1)

2. 2 + 0 = 2 :

3. 2 = 2. Here we can observe the equality.

14. Write a two-column proof.

scZoUnD [109]

Given:

$\bold{ 8x=4y-20} \\\\ \bold{ y=13}$

Prove:

$\bold{x=4}$

Solution:

$\to \bold{8x=4y-20}..........(i)\\\\\to \bold{ y=13}........................(ii)$

Putting the value of equation (ii) into the equation (i):

$\to \bold{8x=4(13)-20}\\\\\to \bold{8x=52-20}\\\\\to \bold{8x=32}\\\\\to \bold{x=\frac{32}{8}}\\\\\to \bold{x= 4}\\\\$

putting the value x into the equation (i):

$\to \bold{8(4)=4y-20}\\\\\to \bold{32=4y-20}\\\\\to \bold{32+20=4y}\\\\\to \bold{52=4y}\\\\\to \bold{y=\frac{54}{4}}\\\\\to \bold{ y= 13.5}$

Therefore, the value of x= 4

The lion population in a certain reserve drops by 5\%5%5, percent every year. Currently, the population's size is 200200200.

EastWind [94]

Answer:

$P(t) = 200\cdot 0.95^t$

Step-by-step explanation:

The lion population in a certain reserve drops by 5\%5%5, percent every year. Currently, the population's size is 200200200.

Write a function that gives the lion population size,

Each year, the population drops to 95% of its previous value. (100 - 5)%

That is, the population is multiplied by 0.95 each year.

Repeated multiplication is signified by an exponent.

Here, that exponent is the number of years from today (t).

<h3>There fore, The population function can be written as ...</h3><h3 /><h3> P(t) = 200·0.95^t</h3><h3> $P(t) = 200\cdot 0.95^t$ </h3>

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 2 cos 3θ

Nina [5.8K]

Take a quick peek at brainly.com/question/10417591
that's how you test for the y-axis, x-axis and origin

recall your symmetry identities, cos(- θ) = cos(θ)

so, simply replace θ for those values, and if the resultant function looks exactly like the original, then it has that symmetry.
