How can you multiply a letter

Answer:

i thinK that you SHOULD DIVIDE 100 BY 35

Step-by-step explanation:

2.87

The resulting expression after expansion is 110x - 1200

Given the function P(x) = 140x - (30x + 1200)

To solve the literal equation, we will have to simply expand the bracket using the distributive law.

According to the law  a(b+c) = ab+ac

You can see that a was distributed over "b" and "c"

For the expression, we will distribute -1 over 30x and 1300 to have;

P(x) = 140x -(30x) - (+1200)

P(x) = 140x - 30x - 1200

P(x) = 110x - 1200

Hence the resulting expression after the expansion is 110x - 1200

Answer:

The shortest distance from a point to a line is the perpendicular from the line to the point

The equation of the given line is -x + 2·y = 14, which can be written in slope and intercept form as follows;

-x + 2·y = 14

2·y = 14 + x

y = 14/2 + x/2 = x/2 + 7

y = x/2 + 7

The slope, m₁ = 1/2 and the y-intercept = 7

Therefore, the slope, m₂, of the perpendicular line to the line -x + 2·y = 14 which was rewritten as y = x/2 + 7 is m₂ = -1/m₁ = -1/(1/2) = -2

Therefore, we have that the slope of the line from A(-1/4, 5) to the line -x + 2·y = 14, is -2

The equation of the line is therefore;

y - 5 = -2(x - (-1/4))

y - 5 = -2·x - 1/2

y = -2·x - 1/2 + 5 = -2·x + 9/2

y = -2·x + 9/2

The coordinates of the point on the line -x + 2·y = 14 (y = x/2 + 7) that coincides with the perpendicular from the point A(-1/4, 5) is therefore given as follows;

-2·x + 9/2 = x/2 + 7

9/2 - 7= x/2 + 2·x

-2.5 = 2.5·x

x = -2.5/2.5 = -1

x = -1

y = x/2 + 7 = -1/2 + 7 = 6.5

y = 6.5

The coordinates of the point on the line -x + 2·y = 14 (y = x/2 + 7) that coincides with the perpendicular from the point A(-1/4, 5) is (-1, 6.5)

The distance from A(-1/4, 5) to B(-1, 6.5), is given as follows;

Where;

(x₁, y₁) = (-1/4, 5), and (x₂, y₂) = B(-1, 6.5)

Plugging in the values, we have;

Therefore, the distance from A(-1/4, 5) to the line -x + 2·y = 14 ≈ 1.7 units, rounding to the nearest tenth.

The multiplication property of one is an identity property

The expression is given as:

[tex]\mathbf{1 \times w \times 16}[/tex]

The multiplication property of one states that:

When one is multiplied by any number or expression, the number or expression remains unchanged.

So, we have:

[tex]\mathbf{1 \times w \times 16 = w \times 16}[/tex]

This property is also referred to as the identity property.

The general rule is represented as:

[tex]\mathbf{1 \times a = a}[/tex]

Examples are:

1 * 2 = 2

1 * x = x

1 * ab = ab

And so on

Hence, the multiplication property of one is an identity property

Answer:

-5

Step-by-step explanation:

Subtracting a negative is just like adding a positive. A way to think about this is that the negative cancel each other out are you left with a positive number.

You can rewrite this as -87 + 82.

Then, you solve and get -5.

Answer:

-5

Step-by-step explanation:

When you are subtracting a negative number, it is the same as adding a positive. We can re-write the expression as:

-87 + 82

When adding a negative and positive number, the one with the larger absolute value controls what sign the sum has. In this case the sum would be negative because 87 > 82. Also, we would subtract these absolute values: 87-82 = 5. This has to be negative, meaning the answer is -5.

Answer:

y=6/5x-8

Step-by-step explanation:

Hi there!

We want to find the equation of the line that passes through (5, -2) and has the slope of 6/5

We can write the equation of the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.

Since we are already given the slope of the line, we can immediately plug it into the equation:

y=6/5x+b

Now we need to find b

Since the equation passes through the point (5, -2), we can use it to solve for b

Substitute 5 as x and -2 as y:

-2=6/5(5)+b

Multiply

-2=6+b

Subtract 6 from both sides

-8=b

Substitute -8 as b.

y=6/5x-8

Answer:

51 and 39

Step-by-step explanation:

Let's make this into an equation

a + b = 90

and

a - b = 12

Let's merge them

a + b + a - b = 90 + 12

Focus on a for now

2a = 102

a = 51

Now that we have the value of a, we substitute a in any of the 2 equations

51 + b = 90

Subtract 51 from both sides to isolate b

b = 39

We can prove this by adding and subtracting both numbers

51 + 39 = 90

51 - 39 = 12
