Answer:
3
Step-by-step explanation:
Find the value of x in the equation 4 + x = 7
13km 500m = 13.5 km
The car consume 1 liter of petrol every 6 km, so for 13.5 km it will consume: 13.5 x 1 / 6 = 2.25 liters
From their sum, the numbers are ' x ' and ' 8 - x ' .
From their product, x(8 - x) = 80 .
When you massage and manipulate this equation into the standard
quadratic form, you have
x² - 8x + 80 = 0 .
Applying the quadratic formula to tease out the solutions of this equation,
we find that they are
<em> x = 4 + 64 i</em>
and
<em> x = 4 - 64 i</em>
Answer:
the slope is
y = 5x + 3
