I think it’s-10. Hope it’s right.
Answer:
True. That is a function.
Step-by-step explanation:
A function just means that every input has only one output. The simpler way to do these is the vertical line test. Draw a vertical line anywhere on the graph and see if the vertical line is intersected in two places. If the vertical line is crossed twice, the graph isn't a function.
y is -2/53
Step-by-step explanation:
- Step 1: Given equation is y = 2/5x-3 and x = -10. Substitute value of x to find the solution.
⇒ y = 2/(5 × -10 - 3) = 2/-53 = -2/53
Answer:
a = 3
Step-by-step explanation:
Factor both expressions
x² - x - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)
The factors are - 3 and + 2 , since
- 3 × 2 = - 6 and - 3 + 2 = - 1 , thus
x² - x - 6 = (x - 3)(x + 2)
-----------------------------------
x² + 3x - 18
consider factors of constant term (- 18) which sum to give the coefficient of the x- term (+ 3)
The factors are + 6 and - 3 , since
6 × - 3 = - 18 and 6 - 3 = + 3 , thus
x² + 3x - 18 = (x + 6)(x - 3)
Both expressions have a common factor of (x - 3)
Compare with (x - a ), then a = 3
Answer:
12.57555 rounded to 12.5756
Step-by-step explanation:
34'=34*1/60=0.56°
56''=56/1/3600=0.01555°
12°+0.56°+0.01555°=12.57555°
