Answer:
3. (-3,-2)
Step-by-step explanation:
For an absolute value the equation, the transformations are as shown:
y= ±a|b(x-h)|+k.
'h' and 'k' are the vertex coordinates, meaning if y= |x+3|-2:
h= -3
and k= -2
Therefore, we get:
(-3,-2)
Answer:
Step-by-step explanation:
m = 4
![y -y_{1}=m(x -x_{1})\\\\y - 4 = 4(x -[-1])\\\\y - 4 = 4(x + 1)\\\\y -5= 4x + 4\\\\y = 4x + 4 + 5\\y = 4x + 9](https://tex.z-dn.net/?f=y%20-y_%7B1%7D%3Dm%28x%20-x_%7B1%7D%29%5C%5C%5C%5Cy%20-%204%20%3D%204%28x%20-%5B-1%5D%29%5C%5C%5C%5Cy%20-%204%20%3D%204%28x%20%2B%201%29%5C%5C%5C%5Cy%20-5%3D%204x%20%2B%204%5C%5C%5C%5Cy%20%3D%204x%20%2B%204%20%2B%205%5C%5Cy%20%3D%204x%20%2B%209)
Answer:
Using ∣x∣>a⇒x<−a or x>a, we get
∣3x−7∣>4⇒3x−7<−4 or 3x−7>4
