Answer:
You got the first one right. The second one should be x<-2
Step-by-step explanation:
It is X<-2 because the arrow points left and the circle is not filled in
(Also can I please have Brainliest, I need it to level up)
He has 3 red marbles and 8 overall marbles (5 + 3 = 8)
So the ratio would be 3:8
Hope this helps! Any questions let me know :)
Answer:
<15,-21>
Step-by-step explanation:
u = <3, -1>
v = <-6, -6>
9u + 2v
9 <3, -1>+2 <-6, -6>
<27, -9> + <-12,-12>
<15,-21>
Answer:
A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is (5 ) units. the point (-7, -1) and point (-7, 5) lies in this circle.
Step-by-step explanation:
equation of circle is
(X-center_X)^2 + (y-center_Y)^2 = r^2
==> (x+3)^2 + (y-2)^2 = r^2
Now it passes 1,5 so
4^2+3^2 = 5^2
==> r = 5
when x = -7
y = -1 or 5
$3000 x .04 =$120
$120 x 10 =$1200
$3000+1200= $4200 Total
