x³ + x² - x - 10 =

= x³ - 2x² + 3x² - 6x + 5x - 10

= x²(x - 2) + 3x(x - 2) + 5(x - 2)

= (x - 2)(x² + 3x + 5)

(x - 2)(x² + 3x + 5)/(x - 2)

= x² + 3x + 5

Answer:

x = 10

Step-by-step explanation:

<u>The ratio of corresponding sides of similar figures is same:</u>

3x/20 = (4x + 2)/(20 + 8)
3x/20 = (2x + 1) / 14
3x(14) = (2x + 1)(20)
42x = 40x + 20
2x = 20
x = 10

How many solutions does the system have? \begin{cases} 5y =15x-40 \\\\ y = 3x-8 \end{cases} ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ 5y=15x−40 y=3x−8 C

Ksenya-84 [330]

Answer:

Step-by-step explanation:

Converting the lines into the from $ax+by+c=0$

$5y=15x-40\\\Rightarrow 15x-5y-40=0$

$y=3x-8\\\Rightarrow 3x-y-8=0$

$\dfrac{a_1}{a_2}=\dfrac{15}{3}=5$

$\dfrac{b_1}{b_2}=\dfrac{-5}{-1}=5$

$\dfrac{c_1}{c_2}=\dfrac{-40}{-8}=5$

So, $\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}$ .

Hence, these lines have infinitely many solutions.

What is

Sergeeva-Olga [200]

Answer:

Standard form of the equation is:

∴ $3x+y=23$

Step-by-step explanation:

Given equation:

$y-2=-3(x-7)$

To convert the given equation to standard form of equation:

$A(x)+B(y)=c$

Using distribution.

$y-2=(-3x)+(-3\times-7)$

$y-2=-3x+21$

Adding 2 both sides.

$y-2+2=-3x+21+2$

$y=-3x+23$

Adding $3x$ to both sides.

$3x+y=3x-3x+23$

∴ $3x+y=23$
