Answer:
x f(x)
0 0
1 3
2 6
3 9
4 12
5 15
Step-by-step explanation:
since they gave the point (0,0) and slope 3
y=mx+b
0=3(0)+b
b=0
y=3x and then substitute
From my work, i got 4x+$1.50=48 I hope it helps you.
if i got it wrong please forgive me! also if it is Okie with you, Can i please have brainliest? Thank you!
Answer:
Step-by-step explanation:
the domain of x represents the values that x can be without the function being undefined. the function of square rooting is undefined for negative numbers. so in order to find the domain, you must ensure that the "stuff" in the square root is greater than, or equal, to zero. hence, (4x+9)>= 0. the answer is B
This expression is a good candidate for "factoring by grouping." I note that the first 2 terms and the last 2 terms share a common factor, 2x+1:
8x^3 + 4x^2 - 18x - 9
4x^2 *(2x + 1) -9 (2x+1)
This can be re-written as (2x+1)(4x2-9)
The latter factor is also easily factorable:
(2x+1)(2x-3)(2x+3) (answer)
Answer:
The reference angle for 155° is 25°
Step-by-step explanation:
The reference angle is the angle that the angle arm makes with the x-axis be it clock wise or anti-clock wise.
The reference angles are obtained by the following reference
0 - 90° => Angle
90° - 180° => 180 - angle
Our given angle is: 155° so we will use the second rule
The reference angle will be:
180° - 155° = 25°
Hence,
The reference angle for 155° is 25°
