Answer:
Correct option is:
y+7=2/5(x+4)
Step-by-step explanation:
The point-slope form of the line with slope m and passing through the point (x1,y1) is given by:
y-y1=m(x-x1)
Here, we are given line with slope m=2/5
and passing through (x1,y1)=(-4,-7)
i.e. x1= -4 and y1= -7
Hence, Correct option is:
y+7=2/5(x+4)

Step-by-step explanation:
r=(1-tm)
The solutions to f(x) = 64 is x = 7 and x = –7.
Solution:
Given data:
and
To find the solutions when f(x) = 64.
Both are equations of f(x), so equate the given equations, we get
Subtract 15 from both sides of the equation.
49 can be written as 7².
Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.
