If g(x)= x+1/x-2 and h(x)=4-x, what is the value of (g times h)(-3)

Alchen [17]

$g(-3)=\frac{-3+1}{-3-2}=\frac{2}{5} \\ \\ h(-3)=4-(-3)=7 \\ \\ (g\times h)(-3)=7\left(\frac{2}{5} \right)=\boxed{\frac{14}{5}}$

Solve the system of equations algebraically: 2x - y = -1 3x + y = 6

Sindrei [870]

Using substitution method
from the first equ
2x+y=-1
y= -1-2x --------(3)
put equ 3 into equ 2
3x -1-2x=6
3x-2x=6+1
x =7
put x+7 into equ 1
2(7) + y = -1
14 + Y =-1
y= -1-14
y=-15
so
x=7 and y=-15

Found out g 2(g - 15) = -26 Please help

Answer: $g=2$

Step-by-step explanation:

To solve this exercise you need to remember the following properties:

1. The Distributive property states that:

$a(b+c)=ab+ac\\\\a(b-c)=ab-ac$

2. The Addition property of Equality statest that:

If $a=b$ , then $a+c=b+c$

3. The Subtraction property of Equality statest that:

If $a=b$ , then $a-c=b-c$

4. The Division property of Equality statest that:

If $a=b$ , then $\frac{a}{c}=\frac{b}{c}$

5. The Multiplication property of Equality statest that:

If $a=b$ , then $a*c=b*c$

Given the equation:

$2(g - 15) = -26$

You must solve for "g" in order to find its value:

- Apply the Distributive property:

$2g - 30= -26$

- Apply the Addition property of Equality adding 30 to both sides of the equation:

$2g - 30+30= -26+30\\\\2g=4$

- Apply the Division property of Equality dividing both sides by 2:

$\frac{2g}{2}=\frac{4}{2}\\\\g=2$
