Step-by-step explanation:
what we trying to find the value of x and y
20x+6=y
x intercept,y=0
20x+6=0-6
20x/20=-6/20
×=-0.3
y intercept,x=0
20(0)+6=y
0+6=y
6=y
(-0.3,0)
19x+7=y
y intercept,x =0
19(0)+7=y
0+7=y
7=y
x intercept,y=0
19x+7=0-7
19x=-7
19x/19=-7/19
x=-0.37
Answer: 600, 648, kite
Step-by-step explanation:
area of trapezoid
use formula h(b1+b2)/2
h = 12
b1 = 44
b2 = 56
plug in numbers to get
12(44+56)/2
= 600
area of kite
use formula pq/2
p = height = 12 + 12 = 24
q = length = 44 + 10 = 54
plug in numbers to get
24*54/2
= 648
larger area
since 600 < 648, max will choose the kite
Answer:
It will take them 3.43 hours.
Step-by-step explanation:
Let T denote the total cookies that need to be cocked. Observe that:
- If Rosanne finishes the cookies in 6 hours, that means that she can make
cookies per hour. - If Dorothy finishes the cookies in 8 hours, that means that she can make
cookies per hour.
Then, by 1) and 2), if they work together would we able to make
cookies per hour.
Therefore, in order to finish the T cookies they will need 
4x+1+57=90
4x+58=90
4x=32
X=8
The value of x can be found by adding the two angles and setting them equal to 180 because they are on a straight line.
3h + 18 + 15h = 180
18h + 18 = 180
18h = 162
h = 9
So the value of h is 9
