Answer:

y = 2 x – 5

Step-by-step explanation:

We can check all of them starting with equation 1.

y = x + 3

3 = 4 + 3

3 = 7

NOT TRUE

Equation 2:

3 = 3(4) - 4

3 = 12 - 4

3 = 8

NOT TRUE

Equation 3:

3 = 2(4) - 5

3 = 8 - 5

3 = 3

TRUE!

This means the last equation is not true.

Answer:

Step-by-step explanation:

Step-by-step explanation:

(3t + 4) + (4t + 3)

Part a

Remove parentheses

3t + 4 + 4t +3

Add

7t + 7

Part b

3t has the same variable ("t") as 4t. And 4 and 3 are both constants (or numbers). Thus, you can add the 3t and 4t together and add 3 and 4 together

Answer:

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Step-by-step explanation:

A slope with a greater absolute value indicates a steeper line. The direction of a line is either increasing, decreasing, horizontal or vertical.

Answer:

So Cody increase his savings by 87.5%

Step-by-step explanation:

We are given Cody's original savings = $40

We are given his new savings total = $75

Now, in order to find out the percentage we have to first find out by how much did he increase his savings:

Increase in savings = $75 - $40 = $35

So now we have the increase in savings we can find out the percentage:

[tex]increase(\%) \: = \frac{increase \: in \: savings}{original \: savings} \times 100[/tex]

Now we plug in our values that we found:

[tex]increase(\%) = \frac{35}{40} \times 100\\ increase(\%) = 87.5\%[/tex]

So Cody increase his savings by 87.5%

Answer:

a.  90 degrees (given)

b. 270 degrees (360-90)

c. 16π  (Circumference= diameter * π, diameter= 2r= 2(8)=16, so c= 16*π)

d. 4π (That section is a semicircle, so length should be 1/4 the circumference)

e. 12π (This section is 3/4 the circumference)

f. 64π (Area= πr^2, and r^2= 8^2= 64, so 64π)

g. 16π (That section is 1/4 the area)

Answer:1/8

Step-by-step explanation:

If we divide both the top and the bottom by 5 since we know that 125 is a multiple of 5, we get 25/200. Divide both by 5 again to get 5/40 we then simplify to get 1/8.

Answer:

0.05

Step-by-step explanation:

Answer:

Simplifying

12x + 2y = 18

Solving

12x + 2y = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

12x + 2y + -2y = 18 + -2y

Combine like terms: 2y + -2y = 0

12x + 0 = 18 + -2y

12x = 18 + -2y

Divide each side by '12'.

x = 1.5 + -0.1666666667y

Simplifying

x = 1.5 + -0.1666666667y

Answer:

Hi

Step-by-step explanation:

First, you need to subtract both sides by 12x

12x+ 2y=18

-12x         -12x

That will give you: 2y= 18-12x

Next, you need to deviede both sides by 2

2y/2= 18-12x/2

That gives you the answer:

y= 18-6x

Answer:

4y-12

Step-by-step explanation:

To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted).

If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks simply of distributivity.

The equivalent value of the expression is A = 4y - 12

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 4 ( y - 3)

On simplifying the equation , we get

A = 4 ( y - 3 )

So , the left hand side of the equation is equated to the right hand side by the value of A = 4 ( y - 3 )

Opening the parenthesis on both sides , we get

A = 4 ( y - 3 )

Using the distributive property , we get

A = 4 ( y ) - 4 ( 3 )

On further simplification , we get

A = 4y - 12

Taking the common factor as 4 , we get

A = 4 ( y - 3 ) = 4y - 12

Therefore , the value of A = 4y - 12

Hence , the expression is A = 4y - 12
