-5(2w+1)=25 how do I solve this problem
Answers
Answer:
Step-by-step explanation:
Divide by - 5
-5(2w + 1) / - 5 = 25 / - 5
2w + 1 = - 5
Subtract 1 from both sides.
2w + 1 - 1 = - 5 - 1
2w = - 6
Divide by 2
2w/2 = -6/2
w = - 3
-5(2w+1)=25
Multiply both sides by -5
(-5)(2w)=-10w
(-5)(1)=-5
-10w-5=25
Move -5 to the other side. Sign changes from -5 to +5.
-10w-5+5=25+5
-10w=30
Divide by -10 for both sides
-10w/-10=30/-10
w=-3
Answer: w=-3

y=mx+b
m=slope
b=y-intercept.
1) We need to know the value of the slope (m):
Given two points (x₁,y₁) and (x₂,y₂) the slope of the line passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
We choose two points of this line:
(-1,-8)
(4,2)
The slope will be: m=(2+8)/(4+1)=10/5=2
2) we have to find the y-intercept (b) of this line:
we choose any point of this line: for example (4,2) and plug in this point in this equation:
y=mx+b
therefore:
2=2(4)+b
2=8+b
b=2-8
b=-6
3) we can already make up the equation:
Data:
m=2
b=-6
y=mx+b
y=2x-6
Answer: y=2x-6
