Answer:option B & D are correct
Step-by-step explanation:
Given options are
A B C D E
Tether ball pole shadow 1.35 1.8 3.75 0.6 2
Flagpole shadow 3.4 4.08 8.35 1.36 4.8
Ratio of corresponding height & shadows should be same
3 meter tall tether ball pole and a 6.8 tall flagpole
=> Ratio = 6.8/3 = 68/30 = 34/15
A - 3.4/1.35 = 340/135 ≠ 34/15( 306/135)
B - 4.08/1.8 = 408/180 = 34/15 = 34/15 ( Correct option)
C 8.35/3.75 = 835/375 = 167/75 ≠ 34/15( 170/75)
D 1.36/0.6 = 136/60 = 34/15 = 34/15 ( Correct option)
E 4.8/2 = 48/20 = 12/5 = 36/15 ≠ 34/15
option B & D are correct

Answer:
Use the graphing calculator to graph the system of equations and find the solution where x is the total hats sold and y is the total t-shirts sold.
x + y = 152,
8.5x + 12y = 1,656
How many hats were sold?
hats
Step-by-step explanation:
A(-7,4) and B(0,6);
A(x₁,y₁) and B(x₂,y₂)
Equation form : y =mx+b
1st Calculate the slope m:
m=(y₂-y₁)/(x₂-x₁) = (6-4)/(0+7), m = 2/7
the equation becomes: y= 2/7.x +b
2nd Calculate b. to that end you plug any coordinates (either A or B) in the equation y=2/7.x + b:
Let's say I selected B(0,6)
6=2/7(0) +b and b =6
The final equation : y =(2/7).x + 6
