The answer is B.
The formula for axis of symmetry is -b/2a.
The b value is -8 and the a value is 1.
Plug it in.
-(-8)/2(1)
8/2(1)
8/2=4
Answer:
Step-by-step explanation:
15. (x + 6)(x + 1)
16. (m - 19)(m + 2)
17. (y - 8)(y - 2)
18. (p + 12)(p - 3)
19. (c - 15)(c + 3)
20. (w - 8)^2
21. (a + 15)(a - 2)
22. (x - 30)(x + 3)
23. 3(5r + 4)(5r - 4)
24. 5(3x - 1)(3x + 1)
25. m^2n(1 - n)(1 + n)
26. 6a(a - 2b)(a + 2b)
27. 3(x^2 + 5x - 24)
3(x + 8)(x - 3)
28. 2(m - 1)^2
29. x(x^2 + 9x - 52)
x(x+13)(x-4)
30. 4y(y^2+y-30)
4y(y+6)(y-5)
2^9 x 32 in exponential form would be 2^14 (two to the fourteenth power)
Answer:
Step-by-step explanation:
f(x)=3(2^x)+6 so
f(3)=3(2^3)+6
f(3)=3(8)+6
f(3)=24+6
f(3)=30
The procedure to rewrite the standard form in slope intercept form is as shown below.
<h3>How to rewrite an equation in Slope Intercept Form?</h3>
The standard form of the equation of a line is;
ax + by + c = 0
Slope intercept form is;
y = mx + c
Intercept form is;
x/p + y/q = 1
To Convert ax + by + c = 0 into y = mx + c
1) Move ax and c to the right hand side to get;
by = -ax - c
Divide both sides by b to get;
y = - ax/b - c/b
Comparing to slope intercept form, we can say that;
Slope = -a/b
y-intercept = -c/b
If we are using y = mx + b as slope intercept form, this will also be accurate because we will just switch c with b in the standard form to arrive at same answer.
