(0,1)(2,7)
slope(m) = (7-1) / (2-0) = 6/2 = 3
y = mx + b
slope(m) = 3
use either of ur points...(0,1)....x = 0 and y = 1
now sub and find b, the y int
1 = 3(0) + b
1 = b
so ur equation is : y = 3x + 1....or 3x - y = -1
Answer:
120
Step-by-step explanation:
1. if x times 80 is 12. you can divide 12 by 80 to get the percent. That is 15 percent.
2. so now you have to find 15 percent of a number = 18. you can solve that by dividing 18 by .15.
3. that is 120
Answer:
it's already a coterminal angle. the goal is too get the degree into that range of 0-360.
For example, the degree 450 would be 90.
450-360 = 90
So, 130 is your answer
T = Total income
N = Number of purses
35N = the selling price of each purse
17N = Cost of each purse
T = 35*N - 17*N - 75
T = 18N - 75
If she wants here total income to be 350 dollars, it will take
T = 350 ; N = unknown.
350 = 18N - 75 Add 75 to both sides.
350 + 75 = 18N
425 = 18N
Rounded N = 24 <<<< Answer. The actually number is 23.611 but you can't sell 0.611 of a purse.
Answer:
h=13
P=5
b=12
Step-by-step explanation:
- tanA=<em>p</em><em>÷</em><em>b</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>2</em>
- sin<em>A</em><em>=</em><em>p</em><em>÷</em><em>h</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>3</em>
- <em>c</em><em>o</em><em>s</em><em>A</em><em>=</em><em>b</em><em>÷</em><em>h</em><em>=</em><em>1</em><em>2</em><em>÷</em><em>1</em><em>3</em>
