### Answers

**Answer:**

k = 1 or 2 or 5 or 10

**Step-by-step explanation:**

Suppose GCD is k, 2 numbers are kA and kB

LCM is k*A*B,

GCD*LCM: k*(k*A*B) = 200

k² * A*B = 200

A*B could be 1 , 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200

k² (k is integer) could be 1, 4, 25, 100

k = 1 or 2 or 5 or 10

One gallon is approximately 3. 875 liters. Mario buys 1. 5 gallons of gasoline for his lawn trimmer. How many liters of gasoline, to the nearest tenth, did Mario buy?.

### Answers

Based on the amount of **gasoline **Mario bought in **gallons**, the amount in **liters **would be **5.8 liters. **

A **single gallon **is equivalent to** 3.875 liters. **

If Mario bought** 1.5 gallons** of **gasoline**, the amount he bought in **liters **would be:

=* Gasoline in gallons x Number of liters per gallon *

= 1.5 x 3.875

= 5.8125

**= 5.8 liters **

In conclusion, **Mario **bought **5.8 liters **of **gasoline**.

a point moves so that it's y-coordinate is always 2 less than it's x-coordinate.

1) write an equation for it's path

2)where does it cross the x-axis

3) where does it cross the y-axis

4) what is it's slope

### Answers

**Step-by-step explanation:**

y is always 2 less than x

1) y = x- 2

2) where does it cross the x-axis ? that means y = 0.

0 = x - 2

x = 2

3) where does it cross the y-axis ? that means x = 0

y = 0 - 2 = -2

4) the slope is always the factor of x.

in

y = x - 2.

the factor of x is simply +1.

If its** y-coordinate** is always** 2 less** than its **x-coordinate, **this is expressed as **y = x - 2**

Slope and equations

From the** given** information

Let the y-coordinate be yLet the x-coordinate be x

If its** y-coordinate** is always** 2 less** than its **x-coordinate, **this is expressed as:

y = x - 2

The equation of the path is y - x - 2

2) The point where th line cuts the x-axis is at y = 0

0 = x - 2

x = 2

The point is at (2, 0)

3) The **point **where th** line cuts** the y-axis is at **x = 0**

y = 0 - 2

y = -2

The **point** is at **(0, -2)**

4) The s**tandard equatio**n of a line is y = mx + b where m is the slope. Given the equation y = x - 2

Comparing:

mx = 1x

m = 1

Hence the** slope **of the **equation** is 1

How many solutions does this system of equations

Infinite

### Answers

**Answer:**

**Step-by-step explanation:**

None

The hint is in the slopes which is the number in front of x. Both equations have a slope of 1/2

The y intercepts are different (4 for the top one 2 for the bottom one). That tells you that you have two lines and not one of top of the other. These two lines never meet, because the slopes are the same. Therefore there are no values that both lines have in common.

That makes the answer none.

### Answers

**Answer:**

(d) 9/2

**Step-by-step explanation:**

The growth factor (multiplicative rate of change) can be found as the ratio of y-values for x-values that differ by 1.

Here, we have ...

x = 0, y = 1

x = 1, y = 9/2

These x-values differ by 1. The growth factor is (9/2)/1 = **9/2**.

Which statement is true about this equation? 3(-y 7) = 3(y 5) 6.

### Answers

The **statement** that is **true** about the equation 3(-y + 7) = 3(y + 5) + 6 is;

Statement A; The equation has one solution, y = 0

The given equation is;

3(-y + 7) = 3(y + 5) + 6

**Expanding** the brackets gives us;

-3y + 21 = 3y + 15 + 6

-3y + 21 = 3y + 21

Using **subtraction property of equality,** subtract 21 from both sides to give;

-3y = 3y

Using **addition property of equality,** add 3y to both sides to give;

-3y + 3y = 3y + 3y

6y = 0

Using **division property of equality**, divide both sides by 6 to get;

y = 0

Answer…

The **inequality **[tex]2x + y >4[/tex] has a **slope **of -2, and the **y-intercept **of 4

The **inequality **is represented as:

[tex]2x + y >4[/tex]

Subtract 2x from both sides

[tex]y >4 - 2x[/tex]

Rewrite the **inequality **as:

[tex]y >- 2x+4[/tex]

The **linear inequality **is represented as:

[tex]y >mx+c[/tex]

Where:

m represents the **slope**c represents the **y-intercept**

So, by comparison:

[tex]m = -2[/tex]

[tex]c = 4[/tex]

This means that the **inequality **[tex]2x + y >4[/tex] has a **slope **of -2, and the **y-intercept **of 4

question 5. Write an equation of the line that passes through the points (-2, -6) and (4, 6).

Answer in slope-intercept form

### Answers

**Answer:**

y=2x-2

**Step-by-step explanation:**

m=(y2-y1)/(x2-x1)

m=(6-(-6))/(4-(-2))

m=(6+6)/(4+2)

m=12/6

m=2

y-y1=m(x-x1)

y-(-6)=2(x-(-2))

y+6=2(x+2)

y=2x+4-6

y=2x-2

Note that the slope-intercept form is y=mx+b where m=slope and b=y-intercept.
