The second answer i think is the best one
y=-7x+2
m=-7, so that's a negative slope.
b=2, so the y-intercept is (0,2). That's a postiive y-intercept.
Solve 0=-7x+2 to find the x-intercept.
7x=2
x=2/7
The x-intercept is (2/7,0), so that's a positive x-intercept.
Answer is 3.25h = m
That’s because Sarah’s earning 3.25 per hour so if you want to figure out how much money she’s making you can just substitute your value for h. Pls mark brainliest if possible, have a nice day
Answer:
Step-by-step explanation:
Sammi has 2 1/3 feet of rope.
To write this type of fraction = 2 + 1/3 - The integer 2 in the expression is the amount of feet of rope that was cut.
Thus to know the number of 1/2 foot pieces produced, let this number be x. Thus, we have 1/2 of x pieces = 2
x/2 = 2; x = 2x2 = 4.
Thus, Sanmi has 4 pieces of 1/2 foot long piece each of rope.

Answer:
(c) P(x) = x^4 +3x^3 -10x^2 -30x
Step-by-step explanation:
If the polynomial has integer coefficients, its complex or radical roots come in conjugate pairs. That is, -√10 is also a root. The four roots mean the polynomial has degree 4. That eliminates all but answer choice C.
Each root 'a' gives rise to a factor (x -a), so the factored polynomial is ...
P(x) = (x -0)(x -(-3))(x -√10)(x -(-√10))
P(x) = x(x +3)(x² -10) = x(x³ +3x² -10x -10)
P(x) = x^4 +3x^3 -10x^2 -10x
