Answer:
c
Step-by-step explanation:
a.) 3(2)+4(6)= 6+24= 30
b.)3(6)+4(2)= 18+8= 26
c.)3(2)+4(-6)= 6+(-24)= -18
d.)3(-2)+4(6)= -6+24= 18
-18 is less than -1
Less than inequality sign means less than or equal to
Answer:
The correct answer is B
Step-by-step explanation:
Both of their medians are equal and Ami's range is larger than Lolo's range :)
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
Answer:
<h2>A. (0, 4)</h2>
Step-by-step explanation:
The equation of a circle:
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
(h, k) - center
r - radius
We have the equation:
![x^2+(y-4)^2=25\\\\(x-0)^2+(y-4)^2=5^2](https://tex.z-dn.net/?f=x%5E2%2B%28y-4%29%5E2%3D25%5C%5C%5C%5C%28x-0%29%5E2%2B%28y-4%29%5E2%3D5%5E2)
h = 0, k = 4, r = 5
