Which system is equivalent to

Mathematics

1 answer:

Sergio [31]2 years ago

8 0

Answer:

We can find the system equivalent to this one by replacing one of the equations with a multiply of itself, so:

Let’s multiply y = x-2 by 2

2y=2x-4

A system equivalent to this one is

y = -2x^2 (this remains the same)

2y= 2x-4

What is the answer too 2(4w-1)=-10(w-3)+4

Advocard [28]

Answer:

w = 2

Step-by-step explanation:

2(4w - 1) = -10(w - 3) + 4

8w - 2 = -10w + 30 + 4

8w - 2 = -10w + 34

+10w +10w

18w - 2 = 34

+2 +2

18w = 36

18 18

w = 2

If ANQZ - ACBK, find BK. * O BK = 39 O BK = 16 O BK = 65 O BK = 27

patriot [66]

9514 1404 393

Answer:

Step-by-step explanation:

Corresponding sides are proportional in similar triangles, so ...

ZT/ZQ = KF/KB

27/(2x +7) = 45/(4x+1)

27(4x+1) = 45(2x +7) . . . cross-multiply

3(4x +1) = 5(2x +7) . . . . divide by 9

12x +3 = 10x +35 . . . . . eliminate parentheses

2x = 32 . . . . . . . . . . . . . subtract 10x+3

x = 16 . . . . . divide by 2

Then the length of BK is ...

BK = 4x+1 = 4·16 +1

BK = 65

What are the coordinates of the point on the directed line segment from (5,5) to

iogann1982 [59]

Answer:

$(x,y) = (6,2)$

Step-by-step explanation:

Given

$(x_1,y_1) = (5,5)$

$(x_2,y_2) = (8,-4)$

$m:n = 1:2$

Required

Determine the coordinate of the partition

This is calculated using:

$(x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

Substitute values for m,n,x's and y's

$(x,y) = (\frac{1 * 8 + 2 * 5}{1+2},\frac{1*-4 + 2*5}{1 + 2})$

$(x,y) = (\frac{18}{3},\frac{6}{3})$

$(x,y) = (6,2)$
