The area of a circle is pi • radius^2
so
3.4^2 • 3.14 = 36.3
Good luck! The answer is C!
F(-2) = 3(-2)-5 = -11
hope it helps
Answer:
C
Step-by-step explanation:
y=-3x+5
Let's try A: 14=-3*3+5=-9+5=-4 (NOT TRUE)
Let's try B: 17=-3*4+5=-12+5=-7 (ALSO NOT TRUE)
Let's try C: 17=-3*(-4)+5=12+5=17 (TRUE)
Let's try D: 23=-3*6+5=-18+5=-13 (NOT TRUE)
Hope this helps!
Step-by-step explanation:
x^2+2x+7y=15
7y=15-x^2-2x
y=15/7-1/7x^2-2/7x , x ∈ all real numbers
A+b=13
a-b=7
add the two equations using system of equations
2a=20
a=10
10+b=13
b=3
