I think the answer is: a score of <span>38 on a test for which = 27 and s = 10</span>
These angles are corresponding angles, so
128 = 8x
x= 16⁰
Answer is 16⁰.
1) The second selection looks correct, as it is the only one with a minimum at a positive x value, and a y-intercept more than 109.
2) Your choice cannot be correct, as it corresponds to a function with a minimum near x = 1.278/(2*0.056) ≈ 11.4. The function is obviously decreasing at that point, so is not a minimum there. My calculator shows the 4th selection is best.
Answer:
zero slope
it is called a zero slope because A horizontal line has slope zero since it does not rise nor fall.
Answer:
(5, -1)
Step-by-step explanation:
Equation 1: 3x + y = 14
Equation 2: 2x - 2y = 12
Rewrite equation 1 to make y the subject:
⇒ y = 14 - 3x
Substitute this into equation 2 and solve for x:
⇒ 2x - 2(14 - 3x) = 12
⇒ 2x - 28 + 6x = 12
⇒ 8x - 28 = 12
⇒ 8x = 40
⇒ x = 5
Substitute found value for x into either equation and solve for y:
using equation 1:
⇒ 3(5) + y = 14
⇒ 15 + y = 14
⇒ y = -1
Therefore, the solution to the system is (5, -1)
