Answer:
could you do the whole thing
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Given y ∝
then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = - 2 when x = 14 , then
- 2 =
( multiply both sides by 14 )
- 28 = k
y = -
← equation of variation
Answer:
<u>y = -3x + 8</u>
Step-by-step explanation:
<u>Given :-</u>
Point on line = (5, -7)
Slope (m) = -3
<u>To find :-</u>
Equation of line
<u>Solving :-</u>
Using point-slope form of equation,
y - y₁ = m(x - x₁)
y + 7 = -3(x - 5)
y + 7 = -3x + 15
<u>Solution :-</u>
<u>y = -3x + 8</u>
The answer would be y=6x+11
The values of the number is 43
x+21=64
subtract 21 on each side
x = 43
