Answer:
a = -2
b = 1
c = 5
Step-by-step explanation:
Given:
2a + 4b + c = 5 ............(1)
a - 4b = - 6
or
a = 4b - 6 .............(2)
2b + c = 7
or
c = 7 - 2b ...........(3)
substituting 2 and 3 in 1, we get
2(4b - 6 ) + 4b + (7 - 2b) = 5
or
8b - 12 + 4b + 7 - 2b = 5
or
10b - 5 = 5
or
b = 1
substituting b in 2, we get
a = 4(1) - 6
or
a = -2
substituting b in 3, we get
c = 7 - 2(1)
or
c = 5
thus,
a = -2
b = 1
c = 5

Answer:
y is 1
Step-by-step explanation:
<span>It was a phenomenon called thermal inversion, in which the change in temperature caused the air that was in the upper part of the atmosphere to fall, causing the death of 20 people and in turn health problems in another 7,000.</span>
First the function f(x) is multiplied by -3. This involves 2 changes:
a) Multiplication by 3
This implies dilation
b) Multiplication by -1
This implies reflection of function over x-axis
Next x is replaced by x+ 3. This means the function is shifted to left by 3 units.
So this overall transformation results in following 3 changes:
Horizontal Translation, Dilation and Reflection along x-axis
