Ok so to be a solution of both, it mus satisfy both equations
therefor only the first choice is correct because (the following is why the other answers are wrong)
2. solutions can lie on axises
3. it mus satisfy both equations
4. it can lie on or between the axises
answer should be the fist one
You are asked to find the missing value in
... 40 + ? = 70
given that it is also the solution to
... ? + 5 = 35
Either way, you subtract the constant that is on the same side of the equation as the unknown.
... 40 + ? - 40 = 70 - 40
... ? = 30 . . . . the missing value
_____
You can check to see if this also satisfies the equation
... 30 + 5 = 35 . . . . . . . true
Answer:
False.
Step-by-step explanation:
Integers are numbers in this set:
{...,-3,-2,-1,0,1,2,3,...}
The opposite of a number is you just changing the sign of that number. Unless you are asking for the opposite of 0 which is just 0.
Example: The opposite of 5 is -5.
Example: The opposite of -5 is 5.
So the opposite of an integer does not always mean the result will be negative. As you seen above, it could be 0, positive, or negative.
Answer:
2/12
Step-by-step explanation:
4w=2/3
1/4(4w)=1/4 x 2/3
w=2/12
Answer:
c) 18 units
d) 1 second
Step-by-step explanation:
h = -16t² - 4t + 20
c) t = 0.25
h = -16(0.25)² - 4(0.25) + 20
h = 18
d) -16t² - 4t + 20 = 0
4t² + t - 5 = 0
4t² + 5t - 4t - 5 = 0
t(4t + 5) - (4t + 5) = 9
(4t + 5)(t - 1) = 0
t = -1.25, 1
t = 1 second
