Answer:
No. of x-intercepts is equal to the no. of distinct species factors of a polynomial
Since this curve has only one distinct factor i.e (x+7)
The only x-intercepts is -7
(-7,0)
Y intercept would be at (0+7)⁷
Which is (0,7⁷)
Or (0,823543)
Since it's an odd power, branch of the curve for x > 7 would approach positive infinity
Branch for x < 7 would approach negative infinity
Which of the following groups of numbers are all prime numbers? A. 2, 5, 15, 19 B. 7, 17, 29, 49 C. 2, 3, 5, 9 D. 3, 11, 23, 31

Some prime numbers
2,3,5,7,11,13,17,19,23,29,31
just try to divide by those and if you an, then it isn't prim
A. 15/3=5 so not prime
B. 49/7=7, not prime
C. 9/3=3 not prime
D. all prime
answe ris D
Answer:
<h2>5</h2>
Step-by-step explanation:
Given the following angles ∠BOC=x+3, ∠AOB=4x−7, and ∠AOC=21, the expression is true about the angles;
∠AOC = ∠BOC+∠AOB
Substituting the given values into the expression, we will have;
21 = x+3+4x-7
collect the like terms
21 = x+4x+3-7
21 = 5x-4
Add 4 to both sides
21+4 = 5x-4+4
25 = 5x
Divide both sides by 5
5x/5 = 25/5
<em>x = 5</em>
<em></em>
<em>Hence the value of x is 5</em>
