With tax, it would be 107.5% of 625.99. 107.5% is 1.075 in decimal form so you do 1.075(625.99). That gives the rounded answer of $672.94. :)
Answer:
The vertex is the point (-1,2)
Step-by-step explanation:
we have
Convert into vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
----> equation in vertex form
The vertex is the point (-1,2)
The number is composed by two digits, let them be ab, so we have:
a + b = 11
this is a pseudo-equation, we are not multiplying ab or ba, is just the digits order.
ba = ab + 9
The pairs of numbers that could comply with the first equation are:
(2,9)
<span>(3,8)
</span><span>(4,7)
</span><span>(5,6)
</span>But only the last couple <span>(5,6) comply as well with the second condition. Because 65 = 56 + 9
Therefore the unknown number is 56</span>
-6(y+15)= -3y+6
-6y-90 = -3y+6
-6 -6
-6y-96 = -3y
+6y +6y
-96 = 3y
/3 = /3
y= -32
You know 100 cm is one meter. So you multiply 3.9 by 100 = 390
Plz mark mine the brainliest answer:) hope this helped
