Answer:
-8/3
Step-by-step explanation:
First find the slope of the line
3x+y = 1
Solve for y
y = -3x+1
This is in slope intercept form
y = mx+b where m is the slope
The slope is -3
The slopes of perpendicular lines multiply to -1
m* -3 = -1
m = 1/3
The line perpendicular has a slope of 1 / (3) = 1/3
The sum is -3 + 1/3
-9/2 + 1/3 = -8/3
Answer:
Work out the area of this circle. Take pie to be 3.142 and give your answer to 2 decimal places.
Step-by-step explanation:
subtract 4x from both sides
-2y=14-4x
divide each side by -2
y=2x+7
Answer:
Choice A.
Step-by-step explanation:
Let x = price of a helmet, y = price of a bat, z = price of a ball.
Company A can provide 9 helmets, 6 bats, and 12 balls for $525.
9x + 6y + 12z = 525
Company B can provide 10 helmets, 8 bats, and 10 balls for $600.
10x + 8y + 10z = 600
Company C can provide 8 helmets, 5 bats, and 15 balls for $500.
8x + 5y + 15z = 500
Answer: Choice A.
Given:
The table that shows the relationship of the total number of pieces of fruit to the number of bananas.
To find:
Why is 
not equivalent to 
.
Solution:
If a, b, c are real numbers, then
The given fraction is . It can be written as:
The number 3 is multiplied by 2 to get 6. So, the 2 should also be multiplied by 2. The ratio should be 
, not .
Therefore, the correct option is A.
