2x-3y=15 solve and show steps please!!

1 answer:

7 0

Solving for Y:

1) Subtract -2x from both sides: -3y=15-2x

2) Divide by -3 on both sides: y=-5+(2/3)x

Final Answer: y = (2/3)x-5

Pyramid A and Pyramid B are similar. Pyramid A has a volume of 648 m and Pyramid B has a

ryzh [129]

Answer:

the ratio of the surface area of Pyramid A to Pyramid B is: $\frac{36}{49}$

Step-by-step explanation:

Given the information:

Pyramid A : 648 $m^{3}$
Pyramid B : 1,029 $m^{3}$
Pyramid A and Pyramid B are similar

As we know that:

If two solids are similar, then the ratio of their volumes is equal to the cube

of the ratio of their corresponding linear measures.

<=> $\frac{Volume of A }{Volume of B}$ = $(\frac{a}{b}) ^{3}$ = $\frac{684}{1029}$ = $\frac{216}{343}$

<=> $\frac{a}{b} =$ $\frac{6}{7}$

Howver, If two solids are similar, then the n ratio of their surface areas is equal to the square of the ratio of their corresponding linear measures

<=> $\frac{surface area of A}{surface area of B} =( \frac{a}{b}) ^{2}$

= $\frac{36}{49}$

So the ratio of the surface area of Pyramid A to Pyramid B is: $\frac{36}{49}$

Find the rectangular coordinates of the point with the polar coordinates (3,3/2_ )

meriva

Polar coordinates: $(r,\theta)$

$r=3,\theta= \frac{3\pi}{2}$

Rectangular coordinates: $(x,y)=(r \cos{\theta},r \sin{\theta})$

$x=r \cos{\theta}=3 \cos{ \frac{3\pi}{2} }=3 \times 0=0
\\ y=r \sin{\theta}=3 \sin{ \frac{3\pi}{2} }=3 \times (-1)=-3$

Rectangular coordinates are (0,-3).

Nat2105 [25]

Answer:

y-2 = 4/3(x+3) (point slope form)

y = 4/3x+6 slope intercept form

Step-by-step explanation:

We need to find the slope of the line 4x -3y =12

Solve for y

Subtract 4x from each side

4x-4x -3y = -4x +12

-3y = -4x+12

Divide by -3

-3y/-3 =-4x/-3 +12/-3

y = 4/3 x -4

The slope is 4/3

We want a line that is parallel, so it will have the same slope

We have the slope and a point, so we can use point slope form

y-y1 = m(x-x1)

y-2 = 4/3(x--3)

y-2 = 4/3(x+3)

Distribute

y-2 = 4/3x +4

Add 2 to each side

y-2+2 = 4/3x +4

y = 4/3x +4+2

y = 4/3x+6
