Answer:
f(x)=-2x+1
Step-by-step explanation:
Once points are plotted, you can use the rise/run method to find the slope which is 2/1=2. Then you can determine that its a negative function since the y values decrease as x increases. Lastly, since the y-intercept is a 1, you can fill in the blanks for the basic y=mx+b equation.
A quadrilaterals angles = 360°
three angles are given, with the fourth as x: 90, 80, 74, x
Add all the angles together and set it equal to 360
90 + 80 + 74 + x = 360
Simplify. Combine like terms
x + 244 = 360
Isolate the x, subtract 244 from both sides
x + 244 (-244) = 360 (-244)
x = 360 - 244
x = 116
116° is your answer

Answer:
1 : 3
2 : 6
4 : 12
9 : 27
Step-by-step explanation:
2nd one do 2 × 3
3rd one 12 ÷ 3
4th one 9 × 3
97+x=27+64
x=27+64-97
x=-6
(Hopefully this is correct)
