Answer:

y = -3x

Step-by-step explanation:

It is easiest to try the answers for x=1.

a) y = 1/-3 = -1/3 ≠ -3

b) y = 1 ≠-3

c) y = 3(1) = 3 ≠ -3

d) y = -3(1) = -3 . . . . . this rule matches the table

Stels [109]

Answer: im pretty sure this is correct

- 1/42 x (21x233y)

Step-by-step explanation:

first convert the expressions (2 3/10x x5/7 x y-2 4/5 x x )

then factor the expression (23/10 x- 5/7 y- 29/6 y- 14/5x )

then collect like terms (1/210 x 483 x - 150 y - 1015 - 588x)

factor the expression (1/210 x 105x 1165y)

Multiply reduce (1/210 x -5 (21x + 233y ))

= -1/42 x (21x233y)

(13x2+9x-4)-(12x2-2x+6)<br> add or subtract the polynomials

bearhunter [10]

Answer:

$x^{2} +11x-10$

Step-by-step explanation:

$(13x^{2} +9x-4)-(12x^{2} -2x+6)$

Remove the brackets and multiply the minus sign through all the numbers in the second polynomial

$13x^{2} +9x-4-12x^{2} +2x-6$

Rearrange in the highest order

$13x^{2} -12x^{2} +9x+2x-4-6$

Simplify

$x^{2} +11x-10$

Given that (2,8) is on the graph of f(x),find the corresponding point for the function -3/4 f(x)

yuradex [85]

Answer:

Corresponding point to (2,8) along -3/4 f(x) = ( -1.5 , -6 )

Explanation:

When a graph f(x) is multiplied by a factor k, the points on the graph also changes by (kx, ky).

Here it is given that (2,8) is on the graph of f(x)

Now we need to find corresponding point to (2,8) along -3/4 f(x)

x - coordinate = $\frac{-3*2}{4} =-1.5$

y - coordinate = $\frac{-3*8}{4} =-6$

So corresponding point to (2,8) along -3/4 f(x) = ( -1.5 , -6 )
