Answer:
x=13
Step-by-step explanation:
180 is the total degree of any triangle. Divide by 3 and you get 60 degree angles. Subtract 8 and you gey 4x=52. Divide then to get 13
Answer:
Domain: [2,∞)
Range: [0,∞)
Step-by-step explanation:
Domain are the values of <em>x</em> allowed for the function.
In this function, because we have a square root, we cannot have numbers in the domain such that the root contains a negative number, because the function would not be defined in real numbers.
Thus, the domain is:
Domain= x-2 ≥ 0
Domain = x ≥ 2
Or what is the same [2,∞)
And the range is the values that the function returns for every number in the domain. Since our domain is the values of x greater than or equal to two:
We can see that the minimum value of y = f (x) is 0 and the greatest number that the function can return to us has no limit, so the range is:
Range: [0,∞)
the answer to the question
Answer:
<em>21 minutes</em>
Step-by-step explanation:
Using the formula to calculate the time expressed as;
Speed = Distance/Time
Given:
Distance = 7/8 miles
Speed = 2 1/2 mi/hr
Required
Time in minutes
Substitute the given values into the formula;
Recall that:
S = D/T
T = D/S
Time = 7/8 ÷ 2 1/2
Time = 7/8 ÷ 5/2
Time = 7/8 * 2/5
Time = 7/4 * 1/5
Time = 7/20 hour
Since 1 hour = 60 minutes
7/20 hour = (7/20 * 60)minutes
7/20 hour = 7 * 3
7/20 hour = 21 minutes
<em>Therefore it will take them 21 minutes to get to the campsite</em>
Answer:
x =
Step-by-step explanation:
Given
- 4(3 + x) + 5 = 4(x + 3) ← distribute parenthesis on both sides
- 12 - 4x + 5 = 4x + 12 , that is
17 - 4x = 4x + 12 ( subtract 4x from both sides )
17 - 8x = 12 ( subtract 17 from both sides )
- 8x = - 5 ( divide both sides by - 8 )
x = =
