6y - 12 = -3x

Which shows the equation in standard form?

10 - 2(x - y) = 3x + 1

Answers

Answer 1

Answer: standard form for first one is
ax+by=c

6y-12=-3x
add 3x both sides
3x+6y-12=0
add 12
3x+6y=12

second one
distribute (don't forget double negative y)
10-2x+2y=3x+1
minus 3x both sides
10-5x+2y=1
minus 10 both sides
-5x+2y=-9

the equations are
3x+6y=12
-5x+2y=-9

Answer 2

Answer: The standad form of linear equation is of the form Ax + By = C, where A, B and C are integers.
Here, the standard form of the eduation 6y - 12 = -3x is 3x + 6y = 12

A wrestler is trying to gain weight for an upcoming match. His current weight is 105. In the formula shown, W = weight, p = pounds and t = time(weeks). He has 6 weeks before his match and has a goal weight of 123 pounds. Determine the minimum number of pounds he must gain per week to meet his goal. A) 1 pound B) 2 pounds C) 3 pounds D) 4 pounds

Answers

Answer:

Option C) 3 pounds.

Step-by-step explanation:

A wrestler is trying to gain weight for an upcoming match.

He has a goal weight = 123 pounds

His current weight = 105 pounds.

How much weight he must gain for his goal = 123 - 105 = 18 pounds

He has only 6 weeks to achieve his goal, therefore we divide is goal (to gain 18 pound) to 6 weeks to get what weight he must gain per week.

= 18 pounds ÷ 6 weeks = 3 pounds per week

He must achieve 3 pounds per week to achieve his goal of 123 pounds.

answer is c) 3 pounds

Sin 300° = 2 sin 150° cos 150° use exact values to show it is true

Answers

Answer:

see explanation

Step-by-step explanation:

left side = sin300° = - sin60° and sin60 = $(√(3) )/(2)$ , thus

sin300° = - $(√(3) )/(2)$

right side

sin150° = sin30° = $(1)/(2)$ and

cos150° = - cos30° = - $(√(3) )/(2)$ , thus

2sin150°cos150°

= 2 × $(1)/(2)$ × - $(√(3) )/(2)$ = - $(√(3) )/(2)$

left side = right side ⇒ True
