By checking it multiply each digit by tenths hundreds or thousands it depends how many digits are there and were there are.

<h3>Solution : </h3>

<h3>Step by Step explanation:</h3>

<h3>1.Switch sides</h3><h3 /><h3> $y\sqrt{6} = \sqrt{24 } + \sqrt{967} \sqrt{600}$ </h3><h3 /><h2 /><h3>2.Simplify√24 + √967 √600</h3>

<h3>3.Divide both side by √6</h3>

<h3> $\frac{y \sqrt{6} }{ \sqrt{6} } = \frac{2 \sqrt{6} }{ \sqrt{6 } } + \frac{10 \sqrt{5802} }{ \sqrt{6} }$ </h3><h3>4.Simplify</h3><h3 /><h3> $y = 2(1 + 5 \sqrt{967} )$ </h3>

Jacob throws an acorn into the air. It lands in front of him. The acorn's path is

agasfer [191]

Answer:

below

Step-by-step explanation:

-3x² + 6x + 6 = 0

x = (-b±√(b²-4ac))/2a

x = (-6±√(36 - 4(-3)(6)))/2(-3)

x = (-6±√108)/-6

x = 1 ± √3

The negative solution is not reasonable for he threw it forwards

Find the missing side length in the image attached.

Aleks [24]

Answer:

? = 56.

Step-by-step explanation:

In the problem, the side 20 corresponds to side 32 and side 20 + 35 corresponds to side 32 + ?.

$\frac{20}{32} =\frac{20 + 35}{? + 32}$

$\frac{5}{8} =\frac{55}{? + 32}$

$\frac{1}{8}=\frac{11}{? + 32}$

? + 32 = 8 * 11

? + 32 = 88

? = 56.

Hope this helps!

Answer:

$\large\boxed{Q2.\qquad C.\ -2x+y=-2}\\\boxed{Q4.\qquad C.\ y=3x+12}$

Step-by-step explanation:

Q2:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (4, 6) and (6, 10). Substitute:

$m=\dfrac{10-6}{6-4}=\dfrac{4}{2}=2$

$y-6=2(x-4)$ <em>use distributive property</em>

$y-6=2x-8$ <em>add 6 to both sides</em>

$y=2x-2$ <em>subteact 2 from both sides</em>

$-2x+y=-2$

Q4:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

Put the slope m = 3 and the coordinateso f the point (-2, 6) to the point-slope form of an equation of a line:

$y-6=3(x-(-2))$

$y-6=3(x+2)$ <em>use distributive property</em>

$y-6=3x+6$ <em>add 6 to both sides</em>

$y=3x+12$
