Answer:

G = 1

h = 2

Step-by-step explanation:

4(2h - 3) - 5h = -6

8h - 12 - 5h = -6

3h - 12 = -6

3h = 6

h = 2

g = 2(2) - 3

g = 4 - 3

g = 1

G= 2h-3
Substitute the value of (g) 4g-5h=-6

4(2h-3) - 5h = -6
8h - 12 - 5h = -6
Now -12 is going other side and it’ll change sign
3h= -6+12
3h = 6
H= 6/3
H= 2



CheckBy substitute the value of h
g= 2h - 3
g = 2(2) - 3
g= 4-3
g = 1

1g = 1
Hence proved.

Answer:  0.6 in 10 % ; 0.4 in 15 %

Step-by-step explanation:

1. (x*10%) + (y*15%)/ x+y=12%

2. x+y = 1  x= 1-y

(0.1x + 0.15y/ x+y= 12/100) * 100

(10x + 15y/x+y = 12)*(x+y)

10x+15y= 12x + 12y

-2x=-3y

2x = 3y   2(1 - y)= 3y

2-2y=3y   2= 5y

y= 0.4

x= 0.6

Use technology to find points and then graph the line y=-5(x-5)+1 following the instructions below.
Svetach [21]

Given:

y=-5(x-5)+1

First, let us find two points from this equation.

We can set values of x and then solve for y.

Let us find the values of y when x = 1, 2, 3, 4, 5

\begin{gathered} y=-5(x-5)+1 \\ y=-5(1-5)+1=21 \\ y=-5(2-5)+1=16 \\ y=-5(3-5)+1=11 \\ y=-5(4-5)+1=6 \\ y=-5(5-5)+1=1 \end{gathered}

We now have a set of points:

(1, 21)

(2, 16)

(3, 11)

(4, 6)

(5, 1)

Since the given plane is limited to values of 10 and -10, the points that we can plot are the points (4, 6) and (5, 1)

The graph would then look like this:
