Write an equation for each line. m=0 and the y -intercept is (0,-2) .

Answers

The equation of a line with slope = 0 and y-intercept = (0,-2) is: y = -2

What is the equation of a line to the curve?A line's equation has the standard form ax + by + c = 0. Here, the variables are x and y, the coefficients are a and b, and the constant term is c.It is a first-order equation with the variables x and y.The coordinates of the point on the line shown in the coordinate plane are represented by the values of x and y.

Now,

Given:

Slope of the given line = 0Coordinates of the y-intercept = (0,-2)

To find: Equation of the line

Finding:

Now, we know that the slope-point form method to find the equation of a line, requires only two things: slope of the line and coordinates of the y-intercept.

The equation so given by the method: y = mx + c, where

m = slope of the line

c = y-intercept

On substituting the given values in the above equation, we get:

=> y = 0x - 2, which the required equation of the line.

Hence, The equation of a line with slope = 0 and y-intercept = (0,-2) is: y = -2.

The result of the multiplication is 24,000.

How to multiply any number with 10?

Multiplication is simply repeated addition, and it is a crucial skill to master.

What occurred if we multiply by ten? 4 * 10 equals 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + What does this add up to? It adds up to 40. Take a look at that. We have a 4 and a 0 just at end.While multiplying whole digits by ten, surely add a 0 to a end of the number to get the answer. 5 * 10 equals a 5 with a 0 just at end: 50. 3 * 10 equals 30 (a 3 with such a 0 at the end).

For the given multiplication;

= 10 x 20 x 30 x 40

This could be written in the terms of 10.

= 10 x 2 x 10 x 3 x 10 x 4 x 10

Simply count the 10 and put the same number of zero after 1 and multiply remaining.

= 2 x 3 x 4 x 10000

= 24 x 10,000

Now, put the same number of zero after the number 24.

= 240,000

Therefore, the given multiplication is solved using simple mental maths.

Answers

a) Yes, by multiplying both sides by 1/8.

b) The inequality is false, thus, there is nothing to solve.

can you use the multiplication property of inequality to solve 8m>-1/10?

Yes, you can.

There is a property that says that if you perform the same operation (multiplicating by 1/8 in this case) in both sides, then the truth value of the inequality does not change.

8m > -1/10

So,  if we multiply both sides by 1/8, we will get:

8m/m > -1/(10*8)

m > -1/80

The inequality is solved.

can you use the division of property to solve -9/2 >3/2?

There is nothing to really solve here, as you can see, the inequality says that a negative number is larger than a positive number, so the inequality is clearly false, and thus, there is nothing to solve.

Lin ordered 250 pens and 250 pencils to sell for a theatre club fundraiser. the pens cost 11 cents more than the pencils. if lin's total order costs $42.50, find the cost of each pen and pencil.

Answers

Using algebraic expression and equation, each pen costs 14 cents while each pencil costs 3 cents.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

Given that the pens cost 11 cents more than the pencils, we can express this as:

x = 11 + y

where x = cost of each pen (cents)

y = cost of each pencil (cents)

If Lin ordered 250 pens and 250 pencils and the total order costs $42.50, we can express that as:

250x + 250y = $42.50

Substitute the value of x in this equation and solve for y.

250x + 250y = $42.50

250(11 + y) + 250y = 4250 cents

2750 + 250y + 250y = 4250

500y = 1500

y = 3

cost of each pencil = 3 cents

x = 11 + y

x = 11 + 3

x = 14

cost of each pen = 14 cents

The division of given rational expression [tex]\frac{3x-6}{12x-24}\div \frac{x^2+5x+6}{3x^{2} -12}[/tex] is [tex]\frac{3(x-2)}{4(x+3)}[/tex] provided x ≠ -3

In this question,

we have been given a complex rational expression [tex]\frac{3x-6}{12x-24}\div \frac{x^2+5x+6}{3x^{2} -12}[/tex]

We need to find the division of given rational expression.

We rewrite given rational expression as,

[tex]\frac{\frac{3x-6}{12x-24}}{\frac{x^2+5x+6}{3x^{2} -12}}\\\\\\= \frac{3x-6}{12x-24}\times \frac{3x^2-12}{x^2+5x+6}[/tex]

First we simplify the quadratic expression x² + 5x + 6

x² + 5x + 6

= x² + 3x + 2x + 6

= x(x + 3) + 2(x + 3)

= (x + 3)(x + 2)

And the simplified form of quadratic expression 3x² - 12 would be,

3x² - 12

= 3(x² - 4)

= 3(x² - 2²)

= 3(x + 2)(x - 2)

So, the given rational expression would be,

[tex]\frac{3x-6}{12x-24}\div \frac{x^2+5x+6}{3x^{2} -12} \\\\\\ = \frac{3x-6}{12x-24}\times \frac{3x^2-12}{x^2+5x+6}\\\\\\=\frac{3(x-2)}{12(x-2)}\times \frac{3(x+2)(x-2)}{(x+3)(x+2)}[/tex]

[tex]\\\\=\frac{3}{12}\times \frac{3(x-2)}{(x+3)}\\\\\\=\frac{3(x-2)}{4(x+3)}~~~~~~~~~~~~~(provided~~x\neq -3)[/tex]

Therefore, the division of given rational expression [tex]\frac{3x-6}{12x-24}\div \frac{x^2+5x+6}{3x^{2} -12}[/tex] is [tex]\frac{3(x-2)}{4(x+3)}[/tex] provided x ≠ -3

Answers

The value of the variable k must equal to - 2 such that the line segment MS is perpendicular to the line segment OP.

What is the value of a variable associated with line segments perpendicular to each other?

According to analytical geometry, two lines are perpendicular to each other if the product of their slopes are equal to - 1. Slopes can be determine by secant line formula:

m₁ = (5 - 8) / [- 2 - (- 6)]

m₁ = - 3 / 4

m₂ = [(k - 2) - (- 20)] / [13 - (k + 3)]

m₂ = (k + 18) / (10 - k)

(- 3 / 4) · [(k + 18) / (10 - k)] = - 1

(- 3 / 4) · (k + 18) = - (10 - k)

- 3 · (k + 18) = - 4 · (10 - k)

- 3 · k - 54 = - 40 + 4 · k

7 · k = - 54 + 40

7 · k = - 14

k = - 2

Answers

Answer:

Multiply 2 by 9, and then 2 by 11, and add it up all together. 18+22=40

Step-by-step explanation:

P (any figure) = sum of all sides

P(6)= sum of 6 sides, where p=perimeter.

P=2+9+11+2+side5+side6

- Notice that two sides are missing their lengths, so we must use other information to solve for their side lengths. Because of this, we label these lengths as side5 and side6, rather than assigning two variables to them since they are different lengths.

Side5=11-2

Side5=9in.

- Notice that side 1 is 2in. Because this side is parallel to side5, it is added to side5 for a total length of 11in.

Side6=9-2

Side6=7in.

- The same idea applies to side6; side 4 is parallel to side6 and adds to it for a total of 9in.

• Substitute the values back into the equation:

P=2+9+11+2+(9)+(7)

P=40in.

So, the perimeter is 40in.

find the equation of the line shown

Answers

The equation of the line is:

y = -x + 9

To identify slope, we use rise/run. However, the line goes down, so there is automatically a negative slope. From the point (0,9), the graph goes to (1,8) which is down one point and to the right one point (-1/1). Because x itself is a variable and equals 1 by default, our slope is -x. The y-intercept is the b in y = mx+b. It is the point on the y-axis where the graph begins. In this case, the y-value of the starting point is (0,9).

The equation of the line is y = -x + 9.

Answers

Answer:

400 ml of lemon juice

Step-by-step explanation:

We know that there are 700 ml of salad dressing, and the ratio of lemon juice to vinegar is 4:3. We know that therefore, there are 7 equal parts. To find how many ml are in one part, we divide 700 by 7, which gives us 100. Then we can multiply that answer by 4 to find how many ml of lemon juice and 3 to find how many ml of vinegar.

100 x 4 = 400

Therefore, Vicky uses 400 ml of lemon juice.
