Step-by-step explanation:

$(a+b)^{2} =a^{2} +2ab+b^{2}$

e.g.

$(x+9)^{2} =x^2+2(x)(9)+81$

$(x+9)^{2} =x^2+18x+81$

If two lines never intersect when graphed. Which of the following best describe the number of solution to this system of linear

serg [7]

Think of when If you cross two lines you get a point where they meet

A point is a solution.

So if the lines never cross, then they would have no point, or A, No Solution

What is 200.96 rounded to the nearest hundredth?

Anvisha [2.4K]

200.96 rounded to the nearest hundredths would be 201 because in you decimal places you have .96 and your thousandths place is 6 so you would round. Up the 9 to 10 so you would have to make 200 into 201 therefore your answer would be 201

Answer:

(a) Output = 37

(b) Input = 9

Step-by-step explanation:

Given

$y =x5 - 3$

Solving (a): Output, when input = 8

This means that, we solve for y when x = 8

So, we have:

$y =x5 - 3$

$y =8*5 - 3$

$y =40 - 3$

$y = 37$

Solving (b): Input, when output = 42

This means that, we solve for x when y = 42

So, we have:

$y =x5 - 3$

$42 = x5 - 3$

Collect like terms

$x5 = 42 + 3$

$x5 = 45$

Divide both sides by 5

$x = 9$

Need help asap pls :)

Answer:

See explanation below.

Step-by-step explanation:

First I'm going to find angle 2. Angle two plus 55 is equal to 115. 180-115=65. 65-55=10 Angle 2 = 10

Next, we can find angle 3. 55+10=65. 180-65=115. Angle 3 = 115

Angle 2 is equal to angle 5, angle 3 is equal to angle 6, and angle 4 is equal to 55.

Angle 5 = 10

Angle 4 = 55

Angle 6 = 115

Now we can find angle 8. 180-115=65. Angle 8 = 65

Angle 11 = 65

Angle 12 = 115

10+115=125 Angle 10 = 125

180-125 = 55 Angle 9 = 55

Angle 14 = 55

Angle 13 = 125

What is the solution to log Subscript 2 Baseline (9 x) minus log Subscript 2 Baseline 3 = 3

sdas [7]

The value of x is $\frac{8}{3}$

Explanation:

The expression is $\log _{2}(9 x)-\log _{2}(3)=3$

Adding $\log _{2}(3)$ to both sides of the equation, we get,

$\log _{2}(9 x)=3+\log _{2}(3)$

Using log definition, if $\log _{a}(b)=c$ then $b=a^{c}$ , we have,

$9 x=2^{3+\log _{2}(3)}$

Using exponent rule, $a^{b+c}=a^{b} a^{c}$ ,

$9x=2^{\log _{2}(3)} \cdot 2^{3}$

Simplifying, we have,

$9x=3\cdot8\\9x=24$

Dividing both sides by 9, we have,

$x=\frac{24}{9}$

Simplifying,

$x=\frac{8}{3}$

Thus, the value of x is $\frac{8}{3}$
