Answer:

put value of y in equation

6x + 3(2x-35) = 15

6x + 6x - 105= 15

12x = 15+105

x = 120/12

x = 10

now put value of x in first equation to find y

y = 2(10) -35

y = -15

What is the complete factorization of r2 - 6r - 9s2 + 9? A) (r - 3 + 3s)(r - 3 - 3s) B) (r + 3 + 3s)(r - 3 - 3s) C) (r - 3 + 3s)

nikitadnepr [17]

$r^2-6r-9s^2+9=r^2-6r+9-9s^2=r^2-2\cdot r\cdot3+3^2-9s^2\\\\\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\=(r-3)^2-9s^2=(r-3)^2-(3s)^2\\\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=(r-3-3s)(r-3+3s)\to A$

Use this expression to name each item. 7m3 + 6r2 – 3r - 8

Vitek1552 [10]

Answer:

In the given expression $7m^3 + 6r^2 - 3r - 8$

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

Step-by-step explanation:

We are given the expression $7m^3 + 6r^2 - 3r - 8$

We need to give variable, coefficients and constant.

Variable: The value of variable may change. It can be represented by x, y or any other letter

Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient

Constant: It is fixed value. It cannot be changed.

So, in the given expression $7m^3 + 6r^2 - 3r - 8$

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

Express the rate 50 yards per minute in feet per second

FrozenT [24]

   (50 yards/minute) x (3 feet/yard) x (1 minute / 60 seconds)

   = (50 · 3 · 1 / 60) (yard-feet-minute) / (minute-yard-second)

   =    2.5 feet/second .
