The vertex is (8,7)
the minimum value is 7
the vertex form is y=(x-8)^2 +7
the minimum value of y=7
i hope this helps!
Answer:
$180
Step-by-step explanation:
$600/$100 = 6
$600 es 6 veces $100.
Por vender $600 gana 6 veces mas que por vender $100.
6 * $30 = $180
Respuesta: $180
Class B has the most consistant sleep because there is less of a difference between 6.87 and 3.65 than the other classes.
A(–2, 4), B(4, 4), C(4, –2), D(–2, –2)
-> select some diagonal: AC
midpoint is at A+(1/2)*AC
-> calculate vector AC:
AC=(4-(-2),-2-4)=(6,-6)
-> calculate half length of AC:
(1/2)*AC=(3,-3)
A+(1/2)*AC=
(-2,4)+(3,-3)=(1,1) which is the midpoint
so the first option is correct
What you do is to substitute the first number for x and the second for y:
(x+7)y=10
a):
(-9+7)*-5=10
(-2)*-5=10
10=10
yes, it's a solution!
b)
(-8+7)10=10
-1*10=10
-10=10
no, not a solution!
c) (-2+7)2=10
5*2=10
yes, a solution!!
d) (3+7)*5=10
50=10
no, not a solution!
