1 answer:

Answer:

D. -2x + 2y = 1

Step-by-step explanation:

<u>When the line is given in standard form:</u>

ax + by = c, it has slope of -a/b

<u>Given line:</u>

4x + 4y = 3

<u>It has a slope:</u>

m = -4/4 = -1

A line perpendicular to the given should have a slope m = 1 as negative reciprocal to the given

<u>Let's see which line has the slope of 1:</u>

1. m = -(-1)/6 = 1/6 - NO
2. m = -4/4 = -1 - NO
3. m = -2/4 = -1/2 - NO
4. m = -(-2)/2 = 1 - YES

Correct option is D

Answer:

90

Step-by-step explanation:

10!/(10-2)!

n!=n(n-1)!

10•9•8!/(10-2)!

10•9•8!/8!

The 8! cancels out and you're left with 10•9

So, your answer is 90

PLISS ANSWER :C DONT ANSWER IF YDK THAnKSSS<br> *also pls look at both images :)*

vovikov84 [41]

Answer:

First image: (6, -1)

2nd image: y = 63

Explanation:

1)

2x + y = 11

1/2x - 5y = 8

y = -2x + 11

1/2x - 5(-2x + 11) = 8

1/2x + 10x - 55 = 8

10.5x - 55 = 8

10.5x = 63

x = 6

2x + y = 11

2(6) + y = 11

12 + y = 11

y = -1

(x , y) = (6, -1)

2)

1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5

2y - 1.2 = 1.8y + 10.8 + 0.6

0.2y - 1.2 = 11.4

0.2y = 12.6

y = 63

Solve the system of equations<br>y = 4x+1<br>y=2+2x-2

Natalija [7]

Answer:

x = -1/2 , y = -1

Step-by-step explanation:

Solve the following system:

{y = 4 x + 1 | (equation 1)

{y = 2 x | (equation 2)

Express the system in standard form:

{-(4 x) + y = 1 | (equation 1)

{-(2 x) + y = 0 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{-(4 x) + y = 1 | (equation 1)

{0 x+y/2 = (-1)/2 | (equation 2)

Multiply equation 2 by 2:

{-(4 x) + y = 1 | (equation 1)

{0 x+y = -1 | (equation 2)

Subtract equation 2 from equation 1:

{-(4 x)+0 y = 2 | (equation 1)

{0 x+y = -1 | (equation 2)

Divide equation 1 by -4:

{x+0 y = (-1)/2 | (equation 1)

{0 x+y = -1 | (equation 2)

Collect results:

Answer: {x = -1/2 , y = -1
