Answer:
y = x - 7
Step-by-step explanation:
x - y - 1 = 0
y = x - 1 .... y = mx + b
m = 1 parallel line has same slope
for (2, -5) m = 1 b = y - mx = -5 - 1x2 = - 7
equation: y = x - 7
<span>4(x2 – 2) = 28
4x^2-8=28 Distributive law of multiplication
4x^2+8=28+8 Additive identity
4x^2=36 ; adding 8 to both sides
x^2 =9, dividing both sides by 4
x= +/- 3</span>
Answer:
12
Step-by-step explanation:
It looks like you're given the equations ...
6px^3 = 3x^6p
Dividing both sides by 3px^3, we get ...
2 = x^3
Substituting that into the left side of the equation, we have ...
6px^3 = 12p
It appears this is the expression you want on the right.
6px^3 = 3x^6p = 12p
Hi there! The first answer is correct.
You start with $5 and save $10 a week until you have at least $45. This situation is represented by the equation, because the variable 10w makes sense with this story and because we have a greater than or equal sign. This means that the left side of the inequality (the savings) must be greater than or equal to $45.
M/n=p-6
n= m/(p-6)
i swapped the n and p-6
