Answer:

Step-by-step explanation:

To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)

5x + 2y = 7

6x –2y = 4

Why is this multiplication allowed? (1 point)

Because the entire equation was multiplied by the same number, the equation remains the same.

What variable will be eliminated when the equations are combined after  the multiplication? (1 point)

The Y variable

Next, add the equations together. Your answer should be a single equation with one variable. (1 point)

11x = 11

Solve the equation for x. (1 point)

X = 1

What is the solution to the system of equations? (1 point)

X = 1 and Y = 1 so the answer is (1, 1)

(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)

[tex]\boxed{\sf A) \:3(v + 5) = 2v - 4 + v}[/tex]

Step-by-step explanation:

[tex]\sf A )\:3(v + 5) = 2v - 4 + v[/tex]

Combine like terms:

[tex]\sf 3\left(v+5\right)=3v-4[/tex]

Expand:

[tex]\sf 3v+15=3v-4[/tex]

Subtract 15 from both sides:

[tex]\sf 3v+15-15=3v-4-15[/tex]

[tex]\sf 3v=3v-19[/tex]

Subtract 3v from both sides:

[tex]\sf 3v-3v=3v-19-3v[/tex]

[tex]\sf 0=-19[/tex]

Answer:

6 tps

Step-by-step explanation:

3 tsp = 1 tablespoons

16 table spoons = 1 cup

therefore 48 teaspoons = 1 cup

therefore 1/8th cup =6 teaspoons

Answer:

(1/8) cup = 6 U. S. teaspoons

Step-by-step explanation:

Do a quick Internet search.  Type '1 cup = teaspoons" into the address line as tho' you were doing a search.  Result:  1 cup = 48 U. S. teaspoons.

We want to know the teaspoon equivalent of 1/8 cup.  To get this, multiply both sides of the above equation by 1/8:

(1/8) cup = (1/8)(48 U. S. teaspoons), or  (1/8) cup = 6 U. S. teaspoons.

Answer:

1,165

Step-by-step explanation:

To solve 1,175 ÷ 5 by using partial quotient we should subtracted 10², when multiplied by 5.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The expression is,

⇒ 1,175 ÷ 5

Now,

Solve the expression 1,175 ÷ 5 by using partial quotients as;

5 ) 1,175 (

   - 500       100

     ------

      675        135

     -675

     --------

         00

Thus,  To solve 1,175 ÷ 5 by using partial quotient we should subtracted 10², when multiplied by 5.

When the point N is dilated, the coordinate of N changes to N'

The coordinate of point N is (8,12)

The given parameters are:

N' = (10,15)

k = 5/4

To calculate the coordinate of N, we make use of:

N * k = N'

So, we have:

N * 5/4 = (10,15)

Multiply both sides by 4

N * 5 = (40,60)

Divide both sides by 5

N = (8,12)

Hence, the coordinate of point N is (8,12)

The height of the object after 3 seconds is 45 feets.

Step-by-step explanation:

The height of an object thrown into the air with an initial upward velocity of 63 feet per second is given as

Where, h(t) is height of the object in feet and t is the time in seconds.

We have to find the height of the object after 3 seconds. So, substitute t=3.

Therefore height of the object after 3 seconds is 45 feets.

Answer:

Exponential decay.  Your growth factor is 1/8, which is between 0 and 1.  Thus, the value is decreasing exponentially.

If the growth factor is greater than 1, you have exponential growth.  Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.
