a=2
Answer:
(m1) slope of DE=(7-1)/(10-a)=6/(10-a)
(m2) slope of EF=(11-7)/(7-10)=4/-3=-4/3
since line are perpendicular
m1m2=-1
6/(10-a) ×-4/3=-1
6/(10-a)=3/4
6×4=3(10-a)
24=30-3a
3a=30-24
a=6/3=2
First you divide sale cost which is $21.75 by the original cost of the shirt being $30.
Once you divide 21.75 into 30 dollars you'll get 0.725
Now you wanna multiply that 0.725 by 100% which will then
give you the total 72.5%

Answer:
(9/5, 8)
Step-by-step explanation:
y = 3 + 5
y=8
y = 5x– 1
8=5x– 1
9=5x
x=9/5
(9/5, 8)
Step-by-step explanation:
plug the coordinate points into the equations and solve for the remaining variable.
b) (2,3) - 5(2) + b(3) = 16
10 + 3b = 16. 3b= 6. b = 2
(0,8) - 5(0) + 2(8) = 16. 0+ 16 = 16. ☆
a) (4,4) assume based on results you meant y squared. (y^2)
(4)^2 = 4k. 16 = 4k. k = 4
(8)^2 = 4(16). 64 = 64. ☆
2x / y = 16
2x because she made twice the shots with free throws then two point shots
