-6x + 12y = 1

Answers

Answer:

x = 1/2; y = 1/3

Step-by-step explanation:

2x + 3y = 2     Eq. 1

-6x + 12y = 1     Eq. 2

Eq. 1

2x + 3y = 2

2x = -3y + 2

x = -3/2 y + 1

Eq. 2

-6x + 12y = 1

De Eq. 1 sabemos que x = -3/2 y + 1

-6x + 12y = 1

-6(-3/2 y + 1) + 12y = 1

9y - 6 + 12y = 1

21y - 6 = 1

21y = 7

y = 7/21

y = 1/3

Eq. 1

2x + 3y = 2

2x + 3(1/3) = 2

2x + 1 = 2

2x = 1

x = 1/2

Respuesta: x = 1/2; y = 1/3

Given h(x)= -5x+3,solve for x when h(x)=3

Answers

Answer:  x = 0

Explanation

The idea is to replace h(x) with 3. Then we isolate x. Follow PEMDAS in reverse to get x by itself.

Here are the steps:

h(x) = -5x+3

3 = -5x+3

-5x+3 = 3

-5x = 3-3

-5x = 0

x = 0/(-5)

x = 0

As a check,

h(x) = -5x+3

h(0) = -5*0 + 3

h(0) = 0 + 3

h(0) = 3

Therefore, the input x = 0 in the domain leads to the output h(x) = 3 in the range. We have confirmed the answer x = 0

Another way to confirm the answer is to use a graphing tool like GeoGebra or Desmos.

Can someone please go into detail on how they simplified this expression? Thanks!: 4a - (4a-3)=4a 1(4a 3) Identity property

I really don't get how they got plus 3
Thanks again!

Answers

Answer:

Step-by-step explanation:

4a - (4a-3)

= 4a -1(4a - 3)

= 4a - 4a + 3    <--- Distributing the -1 over the parenthes

= 3       <---- ( as 4a - 4a = 0)

A scout troop 32 markers along a hiking trail. Each Microway is 9 ounces. On the scale to begin the hike, they put the markers in the backpack. If the empty backpack weighed 3 pounds, how much did the backpack weigh with all the markers in it?

Answers

Answer:

The backpack weighs 21 pounds with all the markers in it.

Step-by-step explanation:

Since they bring 32 markers and each marker is 9 ounces, the weight of all the markers is 288. We know 288 ounces is 18 pounds, so we add 18 to 3. So the backpack weighs 21 pounds with all the markers in it.
