Answer:
Step 4
Step-by-step explanation:
Step 4 is incorrect because when you add the number from the right side, -34, you make it a positive coming to the left side, -17, which stays the same. so 34+-17, will give you 17.
This will make Step 4: Addition property of equality: -17x=40
Therefore Step 5 is also incorrect, and should look like: Step 5: Division Property of Equality: x= 40/-17
Answer:
The answer to this question is 11:3
Answer:
Final answer
= 6y²
Step-by-step explanation:
12y² - 6y²
= 6y²
Answer:
a= 20
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
The diagonal is the hypotenuse and the length and width are the legs
a^2 + 15^2 =25^2
a^2 +225 = 625
Subtract 225 from each side
a^2+225-255=625-225
a^2 = 400
Take the square root of each side
sqrt(a^2) =sqrt(400)
a = 20
Answer: y = -1/3x - 1
Step-by-step explanation:
Slope-intercept = y = Mx + b
M = slope
B= y
