3x-2y=7
3x=7
x=7/3
-2y=7
y=-7/2
so...(7/3,-7/2)
Answer:
f(x)= -|x + 1| + 1
Step-by-step explanation:
This is an absolute value equation, because it's that v-shape that let's us know it will be one. The standard form is
f(x)= a|x - h| + k, where h is the horizontal shift, k is the vertical shift, and a is the dilation factor.
We know that the graph is moved up one, because its vertex is at y = 1. So k = 1.
f(x)= a|x - h| + 1
We also know that it must be negative, because it's upside-down, so <em>put the negative outside the absolute value, not inside.</em>
f(x)= -|x - h| + 1
Lastly, the horizontal shift is left one, so we know that h = -1.
f(x)= -|x - -1| + 1
x minus a negative one equals x plus one, so
<u>f(x)= -|x + 1| + 1 </u>is our final answer.
Answer:
Option (D). 110°
Step-by-step explanation:
Since EB and AD are diameter,
= 
= 180°
= 180° -------(1)
And 
180° = 40° + 
= 140°
Since, 
= 140° [Given 
]
= 70°
From equation (1),
= 180° -
= 180°- 70°
Therefore, measure of arc(EDC) = 110°
Option (D) will be the answer.
The difference between crystalline and amorphous polymers is that in crystalline polymers, the atoms are arranged in a regular pattern such that every part of the pattern is homogenous, while amorphous has irregular lattices.
