**Answer 1**

**Answer:**

6 units

**Step-by-step explanation:**

Just count

**Answer 2**

The **distance **between points A and B is 6 units.

What is Subtraction?

Subtraction can be done for any numbers or **algebraic expressions**. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding **difference**.

In geometry, Distance between two points will be always a **positive **number.

Distance will be 0, if the points **coincide**.

Here on a **number line**, A is marked at -5 and B at 1.

We have to find the distance between A and B.

Distance between A and B = 1 - -5 = 1 + 5 = 6 **units**

Hence distance between A and B is 6 units.

what is the ans

1. Add : 12a²b², -7a²b² , and 9a²b²

2. Subtract : -5y² from y²

need a well explained ans :)

no spams , unwanted ans and plagiarism

kindly stay out if u don't know the ans

### Answers

1. 12a²b² + -7a²b² + 9a²b²

= 14a²b² (the terms a²b² are like terms so don't look at them, just add 12 + (-7) + 9.

= 14 (ab)² (you can write like this too because both a & b are squared).

2. y² - (-5y²)

= 6y² (subtract -5 from 1, y² is the like term).

Write the equation of a line that is parallel to the line y=−4x+1 and goes through the point (2,0).

### Answers

**Answer:**

y=-4x+8

**Step-by-step explanation:**

Hi there!

We are given the line y=-4x+1, and we want to write the equation of the line that is parallel to that line and that also passes through the point (2, 0)

**Parallel **lines have the **same **slope, so it makes sense to find the slope of the line y=-4x+1

The line is written in the format y=mx+b, where m is the slope and b is the y intercept.

As -4 is in the place of where m should be, the slope of the line is -4.

It's also the slope of the line parallel to it.

We can write the slope of the new line in slope-intercept form as well; this is the line so far, after substituting -4 as m:

y=-4x+b

Now we need to find b, which is the value of the y intercept

Remember that are given the point (2,0), which we can use to help solve for b; substitute 2 as x and 0 as y.

0=-4(2)+b

Multiply

0=-8+b

Add 8 to both sides

8=b

Substitute 8 as b into the equation:

y=-4x+8

Hope this helps!

What is the slope if the line is differeniable.

### Answers

**Step-by-step explanation:**

you mean "differentiable" ?

well, remember, a line equation is

y = ax + b

a is the slope

it is always, ALWAYS the factor of x.

now we differentiate the line equation per dx/dy

y' = a

and that is that.

the first derivative of an equation of first degree (that means the highest exponent of the variable is 1), which is a line equation, is a constant : the factor of x.

and since the factor of x is the slope, that means that the constant result of the first derivative of the line equation is the slope.

When resting, a spring measures 73.3 millimeters. When the spring is

compressed, it measures 51.29 millimeters. Find the percent of

decrease in the length of the spring. Round to the nearest percent if

necessary

### Answers

**Answer:**

-30%

**Step-by-step explanation:**

The percentage change in length is given by ...

percent change = ((new length) -(original length))/(original length) × 100%

= (51.29 -73.3)/73.3 × 100%

= -22.01/73.3 × 100% = -0.30027 × 100%

** = -30%**

**The decrease in the length of the spring was 30%**.

What is the equation of the line that passes through points (10,6) and (2,2) ?

### Answers

**Answer:**

y = (1/2)x + 1

**Step-by-step explanation:**

y = mx + b

m = slope = (y2 - y1)/(x2 - x1) = (6 - 2)/(10 - 2) = 4/8 = 1/2

y = (1/2)x + b

Use point (2, 2) to find b.

2 = (1/2)(2) + b

2 = 1 + b

b = 1

Equation: y = (1/2)x + 1

### Answers

**Answer:**

**Step-by-step explanation:**

The slope of the boundary line is positive, so the x- and y-coefficients will have opposite signs when the equation is written in standard form (eliminates choices A, B).

The graph is shaded for x-values greater than those on the boundary line, so the form of the desired equation will be ...

ax -by **≥** c . . . . . for some positive values of a, b, c

This eliminates choice C and indicates the correct choice is the last one:
