<span>(x^2-4x-6) factors into:</span>
(x -5.1623) (x+1.1623)
Therefore x = 5.1623 and x = -1.1623
(4x^2-8x-2) <span>factors into:
(x -2.2247) * (x +2.2474)
</span>
Therefore x = 2.2247 and x= -0.22474
Answer:
f(-2) = 3
Step-by-step explanation:
Given that,
f(x) = x + x + 7
We need to find the value of f(-2).
Put x = -2 in the given function.
f(-2) = (-2) + (-2) + 7
= -2-2+7
= -4+7
= 3
Hence, the value of f(-2) is equal to 3.
Answer:
He sold 1.95 kilograms of apples.
Step-by-step explanation:
First we find out what 3/4 of 7.8 is.
3/4 of 7.8 = 5.85
Next we subtract 7.8 by 5.85
7.8 - 5.85 = 1.95
So, the answer is 1.95
Hope this helps! :)
The slope of the line represents that the remainder of the goal decrease by 8 for each card sold.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
The line passes through the point (1, 8) and (2, 16), hence:

The equation of the line is given by y =8x
