Answer:
X^2+3x
Step-by-step explanation:
in order to get these roots, we would set up the equation to be (x)(x+3). We can then multiply it to get x^2+3x
Answer:
y=-2x+3
Step-by-step explanation:
Slope formula: y=mx+b
m=slope
b=y-intercept
Answer:
add 21 to both sides to get everything on one side
x^2 - 10x + 21 = 0
do factorization, guess and check
(x - 7) (x -3) = 0
x =7, and x =3
Answer:
C
Step-by-step explanation:
When reflecting around the x axis, the x value stays the same and the y- will change.
Answer: 3sin(45) over sin(40)
Using the law of sins that is given, you can write the following proportion.
3/sin(40) = c/sin(45)
All you have to do to solve for C is to multiply by sin(45). In the proportion, the letter are the side lengths and the trig ratios are of the angle opposite the side.
