FINAL ANSWER:
(B) Equation of y =5x
EXPLANATION:
Not a complete representation due to the fact that it only shows students counting by 5. It can be used to create and equation of
Y= 5x because for every x, the y is 5 times more.
EX: 5 students. 5x5= $25. X=5 Y=25
I think the answer is A I’m not sure tho
Answer:
5 2/5
Step-by-step explanation:
2 3/5 + 2 4/5
= 13/5 + 14/5
= 27/5
= 5 2/5
Answer: 1/3 and -1/3
Step-by-step explanation:
Answer:
The measurement of EF is 1.98 units
Step-by-step explanation:
In Δ DEF
∵ m∠E = 90°
∴ FD is the hypotenuse of the triangle
∵ m∠D = 26°
∵ EF is opposite to angle D
- We can use the sine ratio to find it
∵ sin D =
⇒ (opposite side / hypotenuse)
∵ FD = 4.5 units
∴ sin(26) = 
- Multiply both sides by 4.5
∴ 4.5 sin(26) = EF
∵ sin 26° ≈ 0.44
∴ 4.5(0.44) = EF
∴ 1.98 = EF
The measurement of EF is 1.98 units
