You have to put the equations into slope intercept form/y=mx+b.
there's relationship between the points upper left and points in d lower left
Step-by-step explanation:
points in upper right nd points in lower left
the smaller of A+B=a+b
yes
Just sub in ANY number for x and solve for y
5x + 7y = 19.....lets say x = 0
5(0) + 7y = 19
7y = 19
y = 19/7...so when x = 0, y = 19/7.....(0,19/7)
5x + 7y = 19....lets say x = 1
5(1) + 7y = 19
5 + 7y = 19
7y = 19 - 5
7y = 14
y = 14/7
y = 2.....so when x = 1, y = 2......(1,2)
5x + 7y = 19.....lets say x = 3
5(3) + 7y = 19
15 + 7y = 19
7y = 19 - 15
7y = 4
y = 4/7...so when x = 3, y = 4/7.....(3,4/7)
Answer:
plug in -6
-(-6) - 3
the 6 turns into a positive
subtract 3 from 6
= 3
Answer:
75°
Step-by-step explanation:
Recall: SOH CAH TOA
Reference angle = ? = θ
Side length opposite to reference angle = 27
Hypotenuse length = 28
Apply SOH, which is:
![sin(\theta) = \frac{Opposite}{Hypotenuse}](https://tex.z-dn.net/?f=%20sin%28%5Ctheta%29%20%3D%20%5Cfrac%7BOpposite%7D%7BHypotenuse%7D%20)
Substitute
![sin(\theta) = \frac{27}{28}](https://tex.z-dn.net/?f=%20sin%28%5Ctheta%29%20%3D%20%5Cfrac%7B27%7D%7B28%7D%20)
![\theta = sin^{-1}(\frac{27}{28})](https://tex.z-dn.net/?f=%20%5Ctheta%20%3D%20sin%5E%7B-1%7D%28%5Cfrac%7B27%7D%7B28%7D%29%20)
