Answer:
Step-by-step explanation:
Latin American Art: x
African American Art: x+18
European Art: x-15
x+x+18+x-15=78
3x+3=78
3x=75
x=25
Latin American Art: 25
African American Art: 43
European Art: 10
Answer:
2.4
Step-by-step explanation:
8.4/7=1.2
1.2x2=2.4
Hack
for y=ax^2+bx+c
the xvalue of the vertex is -b/2a
and the y value is found by subsituting that for x
so
-b/2a
h(t)=2x^2+4x+7
a=2
b=4
-b/2a=-4/(2*2)=-4/4=-1
the y value
h(-1)=2(-1)^2+4(-1)+7
h(-1)=2(1)-4+7
h(1)=2+3
h(1)=5
(-1,5) is da vertex
Answer is C as all other choices are even numbers therefore make the equation non-integer.
