Answer:
x > 1.5
Step-by-step explanation:
In order to solve for x, we must isolate x on one side of the inequality.
![4.2x > 6.3](https://tex.z-dn.net/?f=4.2x%20%3E%206.3)
x is being multiplied by 4.2 The inverse of multiplication is division. Divide both sides of the equation by 4.2
![\frac{4.2x}{4.2} >\frac{6.3}{4.2}](https://tex.z-dn.net/?f=%5Cfrac%7B4.2x%7D%7B4.2%7D%20%3E%5Cfrac%7B6.3%7D%7B4.2%7D)
![x> \frac{6.3}{4.2}](https://tex.z-dn.net/?f=x%3E%20%5Cfrac%7B6.3%7D%7B4.2%7D)
![x> 1.5](https://tex.z-dn.net/?f=x%3E%201.5)
The solution to the inequality 4.2x > 6.3 is x>1.5
Answer:
![y = - 2x + 5](https://tex.z-dn.net/?f=y%20%3D%20%20-%202x%20%2B%205)
Step-by-step explanation:
Simply simplify the equation from what it is to the slope intercept format:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Answer: n < 6
Step-by-step explanation:
multiply both sides.
4 + n/3 < 6
move the constant to the right.
12 + n < 18
calculate.
n < 18 - 12
solution:
n < 6
The correct answer is D. k= 3
Explain
First , point ( x,y) by factor k
It will become (x/k,y)
The vertex is (-3,-3) of f(x)
And the other vertex is (-1,-3) of g(x)
-1,-3)= (-3/3 ,3)
So the dilation factor is 3
(-1,-3) = (-3 x 1/3 ,3)
Factor is k
g(x)= f(1/3 x)
So k = 3
Because the graph have shrunk f(x) by factor 3
I Hope this make sense to you
Glad I can help you :D
