The answer is 5+8x i think
Answer:
○ The graph of y = -2x² + 3 opens downward and is shifted up.
Step-by-step explanation:
According to the Quadratic Equation, <em>y = Ax² + Bx + C</em>, <em>C</em><em> </em>acts<em> </em>like a y-intercept, and in this case, since both graphs shift up [because both are positive values], we do not pay attention to those. Now, we come over to our <em>A</em>, which makes a BIG difference because both graphs open in opposite directions [one negative, one positive]. With this being stated, we have our answer.

<h3>What are the
simplified mathematical expressions ?</h3>
Scientific notation is used to simplify large numbers in smaller numbers. In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
(8.6 x 
) . (9.1 x 
)
= (8.6 x 9.1) x 
= 78.26 x
= 7.8 x 10
(6.9 x 
) . (4.8 x )
= 33.12 x 
3.3 x
(3.7 x 
) . (4.6 x ) ÷ (1.4 x 
) . (5.7 x 
)
= 1.7 x 10 ÷ 8 x10²
0.21 x 
2.1 x
(3.1 x ) . (5.3 x 
) ÷ (7.3 x ) . (6.1 x 
) = 3.7

Answer:
a 7/20. B 13/20
Step-by-step explanation:
800 X 35% = 280
280/800=7/20
Answer:
A and D
Step-by-step explanation:
It can't be B because of the negative...
It would have to be less than 3.3 since 0.2 is less than and the 3.3 is negative
A and D are the same?
-3.3 * 0.2 = -0.7
