Multiply 9/10 by 2/3:

9 * 2 3*1

--------- = --------- = 3/5 (answer)

10*3 5*1

Three fifths of the whole class has all-correct answers.

Answer: first graph is F(x) = 0.5(x-6) (x+2)

Second graph f(x) = (x - 3) ( x + 1 )

Third graph f(x) = -2(x - 1) (x + 3 )

Identify the zeros of f(x)= (x-7)(x+4)(3x-2) Choices:

Kobotan [32]

Answer:

second option

Step-by-step explanation:

Given

f(x) = (x - 7)(x + 4)(3x - 2)

To find the zeros let f(x) = 0, that is

(x - 7)(x + 4)(3x - 2) = 0

Equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x + 4 = 0 ⇒ x = - 4

3x - 2 = 0 ⇒ 3x = 2 ⇒ x = $\frac{2}{3}$

zeros are x = - 4, x = $\frac{2}{3}$ , x = 7

Very confused on how to do this and I’m only using the circled function so if anyone can help me that would be very helpful :)

I'm pretty sure it'd just be a parabola with is axis at 0 facing upwards and the inverse would be facing downwards

I need to know the answer

antoniya [11.8K]

2 days late, but the answer is no solution. solving a system of equations means finding where they intersect, but by looking at these equations, you know that they never intersect--they're parallel.

they share a slope (2), making them either parallel or "the same line", but the different x-intercepts (9 and -9) mean that they're different lines. they have no solution, or no intersection point, because they're parallel lines.

For the line segment whose endpoints are R(1, 2) and S(6, 7), find the y value for the point located 3 ov`er 4 the distance from

Mrac [35]

Answer:

23/4

Step-by-step explanation:

This means that it is 3/4 of the distance in the x <u>and</u> y coordinates, so it is 3/4 of the way from 2 to 7, and since this is a difference of 7-2=5, then it is 2 + (5 * 3/4) or 2 + 15/4 or 23/4.
