A) write √3×√6 in the form of b√2 where b is the insteger<br><br>b) simplify √8×√18<br>

Bas_tet [7]

Step-by-step explanation:

a.) the given term can be written as

$\sqrt{3} \times \sqrt{3 \times 2}$

$\sqrt{3 \times 3 \times 2}$

$3 \sqrt{2}$

hence the given term is

$3 \sqrt{2}$

where b = 3

b.)

$\sqrt{8} \times \sqrt{18}$

$\sqrt{2 \times 2 \times 2} \times \sqrt{2 \times 3 \times 3}$

$\sqrt{2 \times 2 \times 2 \times 2 \times 3 \times 3}$

$12$

hence the given term is 12

The graph shows the distance, y, that a car traveled in x hours:

vesna_86 [32]

Here, You need to calculate the slope of the graph by taking any two random points, as follows:
(x₁,y₁) = (0,0) & (x₂,y₂) = (1,55)

Now, we know,
y₂-y₁ = m(x₂-x₁)
55-0 = m(1-0)
m = 55/1
m = 55

Here m represents the slope of graph which is nothing but rate of change of distance.

In short, option A will be your answer.

Hope this helps!

Write an equation perpendicular to x - 4y = 20 that passes through the point (4, -3)

Nina [5.8K]

Answer:

y = - 4x + 13

Step-by-step explanation:

In order to do this problem you would need a whole new equation, but you will use what is given to you:

instead of going with:

x - 4y = 20

Turn it into y = mx + b form, also known as slope-intercept form:

x - 4y = 20

-x = -x

_________

- 4y = 20 - x

Then divide both sides by - 4:

$\frac{-4y}{-4} = \frac{-x + 20}{-4}$

You will then get:

y = $\frac{1}{4}x - 5$

From this equation we will only need the slope!

m || = $\frac{1}{4}$

(This slope is for parallel)

but if you want perpendicular to the slope, then we need the negative reciprocal!

Negative reciprocal is a flipped version of the value that is negative, for example:

2 = $-\frac{1}{2}$

Because $\frac{2}{1}$ = 2

Now we will find the perpendicular slope which is:

m ⊥ = - 4

Now substitute this slope into slope intercept form:

y = mx + b

(-3) = -4(4) + b

(Take away parentheses)

-3 = -16 + b

(Move - 3 to the other side, by making it positive, but what you do to one side, you do to the other)

= -13 + 6

(Move - 13 to the other side, by make - 13 into +13)

+13 = +13

________

13 = b

(This is you b, also known as you intercept)

Your answer is:

y = -4x + 13

Please help thank you.

Question 1:
For that point where all the lines intersect to be an incenter, the following must be true
4x - 1 = 6x - 5
Subtract both sides by 6x
-2x -1 = -5
Add both sides by 1
-2x = -4
Divide both sides by -2
x= 2

Question 2:
Plug in x=2 into any of the two equations.

You get 7.

Have an awesome day! :)
