Answer:
y = 1.1
Step-by-step explanation:
Proportion is a statement that two ratios are equal.
It can be written in two ways:
- Two equal fractions
= 
- Two equal sides a: b = c: d.
We can use cross products to find a missing term in it.
Let us solve the question
∵ The proportion statement is 
= 
→ Use the cross multiplication to find y
∵ y × 15.4 = 7.7 × 2.2
∴ 15.4y = 16.94
→ Divide both sides by 15.4 to find y
∵ 
= 
∴ y = 1.1

There are 8 equal parts. Each part is 1/8 of the whole 8/8
Answer/Step-by-step explanation:
1. 
; 3
Let's solve for a.
(subtraction property of equality)
(division property of equality)
Therefore, 3 is a solution to 9 = 2a + 3
2. 
; 7
(- × - = +)
(Subtraction property of equality)
(division property of equality)
Therefore, 7 is not a solution of
3. 
; 1
Therefore, 1 is a solution of .
Answer:
D) y=-4x+2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2-6)/(1-(-1))
m=-8/(1+1)
m=-8/2
m=-4
y-y1=m(x-x1)
y-6=-4(x-(-1))
y-6=-4(x+1)
y=-4x-4+6
y=-4x+2
