1 answer:
Step-by-step explanation:
homework and test grades
88+87+85+86+89/5 is 87% average
then 15+87+55+30/4is 46.74 which round up to an average of 4 7 % as a whole for the course

<h2>
<em>y = ± 5⁄2 x</em> </h2><h2>
<em>y = ± 5⁄2 xThe equation is the left half of the hyperbola. The domain is ( – ∞, – 1⁄5 ]. The range is ( – ∞, ∞ ). The vertical line test indicates that this is not the graph of a function.</em> </h2>
Answer:
x can have two complex solutions, which are:
-2 + i
-2 - i
Step-by-step explanation:
2x² + 8x + 10 = 0
4x² + 16x + 20 = 0
4x² + 16x + 16 = -4
(2x + 4)² = -4
2x + 4 = √-4
2x = -4 ± i√4
2x = -4 ± 2i
x = -2 ± i
So x is equal to -2 + i and -2 - i.
It should be " b "
That should be right but u may want to wait for others to respond to this to make sure
