2. $\displaystyle y = -\frac{5}{7}x + 2$

1. $\displaystyle y = -2x + 4$

Step-by-step explanation:

3. 2x - 5y = −7

- 2x - 2x

__________

$\displaystyle \frac{-5y}{-5} = \frac{-2x - 7}{-5} \\ \\ y = \frac{2}{5}x + 1\frac{2}{5}$

2. 5x + 7y = 14

- 5x - 5x

__________

$\displaystyle \frac{7y}{7} = \frac{-5x + 14}{7} \\ \\ y = -\frac{5}{7}x + 2$

1. 6x + 3y = 12

- 6x - 6x

__________

$\displaystyle \frac{3y}{3} = \frac{-6x + 12}{3} \\ \\ y = -2x + 4$

How do you factor this polynomial as a product of more than two factors?<br> x3+8x2+15x

umka21 [38]

$x^3+8x^2+15x =\\
x(x^2+8x+15)=\\
x(x^2+3x+5x+15)=\\
x(x(x+3)+5(x+3))=\\
x(x+5)(x+3)

The measure of angle F is 130 degrees.

Vitek1552 [10]

130 degrees is the total degrees of the angle,
So if part of that angle was 70 degrees with a missing part you can just subtract to find the missing angle.
(130-70=60)
The missing angle equals 60 degrees

What is the value of X?

algol [13]

Answer:

x = 3

Step-by-step explanation:

ΔABC is 45 45 90 right triangle

The ratio of leg: hypo = a : a√2

Given: hypo AC = 6√2; so AB = BC = 6

ΔBCD is 30 60 90 right triangle

The ratio of short leg : long leg : hypo = x : x√3 : 2x

Hypo. BC = 6 = 2 (3)

So short leg BD = x = 3
