You would divide 121 by 8.
121 / 8 = 15.125 So she did about 15 sit ups in a minute. Hope this helps!
Answer:
∠1=160° and ∠2=20°
Step-by-step explanation:
Let ∠1 = x
∠2 = y
as these two angles are supplementary their sum is 180
that x+y=180 ----(A)
Also given that ∠1 is 20 degree less than nine times the size of ∠2.
Hence
x=9y-20
putting value of x in A and solving for y
9y-20+y=180
10y=180+20
10y=200
y=10
Putting this y in A
x+10=180
x=160
For the equation,
y = 1/2(x+3)^2 -5
The vertice is (-3,-5). Therefore the axis of symmetry is X = -3.
Hello!
I have attached three graphs. The first one for x = 7, second one for y = -1, and third one with both x = 7 and y = -1 on the same graph.
Hope this helps :))
Y=145, I’m not sure about X
