5. Write equations in slope-intercept form for three different lines that intersect at (–2, 3). Show your work.

bixtya [17]

Answer:

Equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5

Step-by-step explanation:

General equation of slope intercept form : $y-y_1=m(x-x_1)$

We are supposed to find equations in slope-intercept form for three different lines that intersect at (–2, 3).

$(x_1,y_1)=(-2,3)$

Substitute the value in the general equation

y-3=m(x+2)

Now substitute any 3 values of m

At m = -1

$\Rightarrow y-3=-x-2 \\\Rightarrow y=-x+1$

At m =0

$\Rightarrow y-3=0 \\\Rightarrow y=3$

At m =1

$\Rightarrow y-3=x+2 \\\Rightarrow y=x+5$

They all intersect at the given point.

So, equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5

Create and solve a linear equation that represents the model, where squares and triangles are shown evenly balanced on a balance

Rina8888 [55]

Let the weight of triangle be x units. You are given that the weight of square is 1 unit.

1) On the left side of the balanced beam you can see 3 triangles and 5 squares. The weight on left side is 3·x+5·1=3x+5 units.

2) On the right side of the balanced beam you can see 2 triangles and 7 squares. The weight on right side is 2·x+7·1=2x+7 units.

3) If the whole system is balanced, then the weights on left and right sides are equal:

3x+5=2x+7.

Solve this equation:

3x-2x=7-5,

x=2 units.

How do you Multiply Radicals?????

Zolol [24]

Answer:

1. $4\sqrt{5}$

2. $10\sqrt{10}$

Step-by-step explanation:

When you multiply radicals, you do the following

$a\sqrt{b}\cdot c\sqrt{d}\\\\=ac\sqrt{bd}$

with that in mind

$\sqrt{16}\cdot \sqrt{5}$

here we don't need to multiply 16 times 5, because 16 = 4^2 and take the square root of it, gives you 4

$=4\sqrt{5}$

$\sqrt{20}\cdot 5\sqrt{2}\\\\\longrightarrow 20 = 2^2\cdot 5\\\\=2\sqrt{5}\cdot5\sqrt{2}\\\\=(2\cdot5)\sqrt{5\cdot2}\\\\=10\sqrt{10}$
