So first of all, know that perpendicular lines have slopes that are a negative reciprocal from each other. So your original equation is in slope-intercept format: y = mx + b, where m = slope
So your slope is -1/9. Now the negative of that would be --1/9 = +1/9. Now the reciprocal of 1/9 is 9/1 = 9 (you just flip the fractions ;).
Now that we have our new slope, let's make an equation of a line with that new slope and the point (1, 7). For that let's switch to the point-slope format: y-k = m(x-h), where h = the x-value and k = the y-value.
Our h = 1 and k = 7
y-7 = 9(x-1)
Answer:The line segment we are required to compute is the solid red line. Let's first compute the diagonal of the rectangle of sides 12 cm and 11 cm. This length is greater than the 12 cm side of the rectangle, so it confirms our initial guess, the longest line segment is 12.89 cm long.
Step-by-step explanation:
A.You have to multiply the Original price(96) by todays discount(1/2)
96×(1/2)=48
Then to find the price 5 days from now you multiply the Original price(96) by the discount 5 days from now(2/3) but this time you subtract what you get from the original price 96×(2/3)=64
96-64=32 or the price of the coat 5 days from now
B. To find how much she would save subtract todays price(48) by the price 5 days from now(32)
48-32=16 She would save 16 dollars
Answer:
1.33 repeating
Step-by-step explanation:
you just do 4 divided by 3.
Please mark as brianliest if i got it right
The answer is $187.5 because you need to multiply 19.50 x 6 and that will equal 117.
$23.50 x 3 = 70.5. Add those two together and it will be $187.5
