Answer:
There are two intersections
Step-by-step explanation:
The number of intersections can be found by calculating the delta of the equation
Δ=b²-4ac
if Δ=0, there is 1 intersection
if Δ>0 there are 2 intersections
if Δ=<0, there are no intersections
where the quadratic equation is in the form ax²+bx+c
Δ=7²-4(2)(6)
=1>0
There are two intersections
Add them together
e.g - 5a +6+6a+7
= 11a+13
<em>The given equation is: E=17/20 D , where E=amount of Euros and D= amount of U.S dollar.
</em>
<em>
</em>
<em>Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get.........
</em>
<em>
E=17/20(1)</em>
<em>E=1/20=0.85</em>
<em>0.85 Euros have the same amount as 1 U.S dollar.
