Answer:
<h3>Y=-21/2x+5</h3>
Step-by-step explanation:
<u><em>SLOPE FORMULA:</em></u>
y₂-y₁/x₂-x₁=rise/run
<u><em>SLOPE-INTERCEPT FORM:</em></u>
y=mx+b
m represents the slope.
b represents the y-intercept.
y₂=(-16)
y₁=47
x₂=2
y₁=(-4)
Solve.
Furthermore, the y-intercept is 5.
y=-21/2x+5
The correct answer is y=-21/2x+5.
To find the answer, we can first find the age of Rolando in four year:
17+4
=21
We can then proceed to find the current age of Marisa,which is 3/2 of Rolando’s age calculated above:
Let Marisa’s age be y.
3/2 y =21
y = 21 × 2/3
y = 42/3
y = 14
Therefore Marisa is currently 14 years old.
In three years, Marisa would be:
14+3
=17
Therefore, she will be 17 years old.
Hope it helps!
Answer:
y=5x-10
Step-by-step explanation:
y+10=5x
y=5x-10
Answer:
15w - 10x + 30.
Step-by-step explanation:
-5(2x - 3w - 6)
= (-5 * 2x) + (-5 * -3w) + (-5 * -6)
= -10x + 15w + 30
= 15w - 10x + 30.

Answer:
y = 6/7
Step-by-step explanation:
The equation given is:
-3 = 7(y - 9/7)
To solve this, we will expand the bracket and afterwards, collect like terms:
-3 = (7*y) - (9/7 * 7)
-3 = 7y - 9
Collecting numeric terms to the left hand side:
-3 + 9 = 7y
=> 6 = 7y
=> y = 6/7
That is the solution.
