Answer:
Daniel spent $ 19.
Step-by-step explanation:
Given that, while shopping for clothes, Tracy spent $28 less than 2 times what Daniel spent, and Tracy spent $ 10, to determine how much Daniel spent the following equation must be performed:
Daniel: X
Tracy: 2X - 28 = 10
2X - 28 = 10
2X = 10 + 28
X = 38/2
X = 19
2x19 - 28 = X
38 - 28 = X
10 = X
So, Daniel spent $ 19.
W=-L+P/2
subtract L to the other side and then diving everything by 2 to get W by itself
Answer: to #3 is no it is not a function
Step-by-step explanation:
Answer:
11 1/5
Step-by-step explanation:
3 1/5 ÷ 2/7 =
16/5 ÷ 2/7 =
KCF (Keep, Change, Flip)
Keep 16/5
Change ÷ to ×
Flip 2/7 to 7/2
16/5 × 7/2
16 x 7 = 112
5 x 2 = 10
112/10
11 2/10
11 1/5
Hope that helps :)
Answer:
1) (x + 12)²+(y+6)²= 28
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√28
h=-12
k=-6
;.centre=(-12,-6)
radius =√28 units
2) x²+(y+7)²=15
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√15
h=0
k=-7
;.centre=(0,-7)
radius=√15 units
3) (x + 4)²+(y - 1)² = 4
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√4=2units
h=-4
k=1
;.centre=(-4,1)
radius=√2units
4) (x+3)²+(y-1)²= 8
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√8=2√2units
h=-3
k=1
;.centre=(-3,1)
radius=2√2units
