Answer:
bottom left, the one that looks like a v
Step-by-step explanation:
You can test if something is a function by looking to see if there is a place where an x has 2 ys. if there are 2 ys for an x it is not a function.
<span>So, x+15 + 2x = 90 </span><span>
<span>Therefore 3x = 90 - 15 = 75 </span>
<span>and so x=25. </span>
<span>So the smaller angles are x+15 = 40 degrees and
2x=50 degrees. </span>
<span>So the larger one is 50 degrees.</span></span>
Answer:
180°, ∠4, ∠5
Step-by-step explanation:
∠1+∠2+∠3 = 180° because, as seen, their sum makes a straight angle. (on the transversal E)
∠2 is equal to ∠4 because of the Alternate Interior Angles theorem
∠1 is equal to ∠5 because of the Corresponding Angles theorem
A function is denoted as y = f (x), where x is the argument or input of the function. This means that from f(6) follows that x= 6, and to get the answer we should replace x with 6.
f(6)=6^2÷ 3 + 6= 36÷ 3 + 6= 12+6= 18
f(6)=18
