Answer:

Step-by-step explanation:

this week sold = $2,760

last week sold = $2,400

the difference from this week to last week = 2700-2400 = 360

that means it increased : 360 / 2400 = 0.15 (100%) = 15%

therefore, the increase of sale is 15%

M-N is $M-N=2x^2+11x-9$

Option B is correct.

Step-by-step explanation:

If $M=5x^2+7x-4$ and $N=3x^2-4x+5$ then find M-N

We need to subtract N from M

We will combine like terms (terms having same variable and exponent) and then solve them:

$M=5x^2+7x-4$

$N=3x^2-4x+5$

$M-N=5x^2+7x-4-(3x^2-4x+5)\\M-N=5x^2+7x-4-3x^2+4x-5\\Combining\,\,like\,\,terms:\\M-N=5x^2-3x^2+7x+4x-4-5\\M-N=2x^2+11x-9$

So, M-N is $M-N=2x^2+11x-9$

Option B is correct.

Solving Quadratic Equations posttest <br><br> A.<br> B.<br> C.<br> D.

beks73 [17]

Answer:

D. $x = 3 \pm \sqrt{10}$

Step-by-step explanation:

$x^2 - 6x - 1 = 0$

$x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

a = 1; b = -6; c = -1

$x = \dfrac{-(-6) \pm \sqrt{(-6)^2 - 4(1)(-1)}}{2(1)}$

$x = \dfrac{6 \pm \sqrt{36 + 4}}{2}$

$x = \dfrac{6 \pm \sqrt{40}}{2}$

$x = \dfrac{6 \pm \sqrt{4 \times 10}}{2}$

$x = \dfrac{6 \pm 2 \sqrt{10}}{2}$

$x = 3 \pm \sqrt{10}$
