Write an equation for each line. y intercept of -2.1, x intercept of 3.5

Answers

the answer should be:
y=3.5x-2.1

The equation of a line with given x and y intercept is y=0.6x-2.1.

What is a x-intercept?

The x-intercept for any curve is the value of the x-coordinate of the point where the graph cuts the x-axis, or we can say that the x-intercept is the value of the x-coordinate of a point where the value of y-coordinate is equal to zero.

Given that, y intercept is -2.1 and x intercept is 3.5.

Here, the coordinates are (0, -2.1) and (3.5, 0)

Now, slope m=(0+2.1)/(3.5-0)

= 2.1/3.5

= 0.6

Substitute m=0.6 and c= -2.1 in y=mx+c, we get

y=0.6x-2.1

Therefore, the equation of a line is y=0.6x-2.1.

A package of blank CDs usually costs $8.50. This week it's on sale for 15% off. What's the discount?

Answers

8.50×0.15= 1.275
1.28 is the amount you get off
8.50 is the original price
7.22 is amount paid

8.50 x .15 = 1.275 (discounted amount)

Subtract the discounted amount ($1.28 from $8.50)

8.50 - 1.28 = 7.22

you are given the measure of angle 4. You also know the following angles are supplementary: Angles 1 and 2, angles 2 and 3, angles 1 and 4. Explain how you can determine the measures of angles 1, 2, and 3.

Answers

If you are given the measure of angle 4, then we know angle 2 is equal since it is a vertical angle. The angle of a line is 180 degrees, so subtract the measure of angle 4 (and/or 2) which will give you the angle measure for both angle 1 and 3, since those are also equal due to vertical angles. Hope that helped! :)

Final answer:

To find the measures of angles 1, 2, and 3, use the fact that angle 1 is supplementary to both angles 2 and 4, and angles 2 and 3 are supplementary. Set up equations and solve them simultaneously to find the measures of the angles.

Explanation:

To determine the measures of angles 1, 2, and 3, we can use the information that angle 1 is supplementary to both angles 2 and 4, and angles 2 and 3 are supplementary. Since angles that are supplementary add up to 180 degrees, we can set up equations to solve for the measures of angles 1, 2, and 3.

Let's represent the measure of angle 4 as x. Then we can write the equations:

Angle 1 + Angle 4 = 180 degreesAngle 2 + Angle 3 = 180 degreesAngle 1 + Angle 2 = 180 degrees

Substituting x for the measure of angle 4, we can solve these equations simultaneously to find the measures of angles 1, 2, and 3.

Can 1.3 be turned in to a fraction

Answers

yes this is the answer

Literal equations
A=bh/2
solve for h

Answers

Multiply both sides by 2
(2a = bh)
Divide both sides by b.
b cancels out on the right side.
(2a/b = h)
Switch sides

Answer: h = 2a/b

The value of the given equation A = bh/2 for h will be (2A)/b.

What is the equation?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation.

As per the given equation,

A = bh/2

Multiply by 2 on both sides,

2A = (bh)/2 x 2

2A = bh

Divide both sides by b,

(2A)/b = bh/b

(2A)/b = h

Hence "The value of the given equation A = bh/2 for h will be (2A)/b".

ten less the quotient of a number and 3 and is 6

Answers

"Ten less" means that we subtract 10. "Quotient" means that we divide.
(x / 3) - 10 = 6 I can show you how to solve for x. Add 10 on both sides of the equation. x / 3 = 16 Multiply both sides of the equation by 3. x = 48
I hope I helped :)

Final answer:

The question is about solving the algebra equation derived from the statement 'Ten less the quotient of a number and 3 is 6'. The equation is x/3-10=6 and through algebraic operations, we find that the solution is x = 48.

Explanation:

The subject of your question is Algebra, which is a branch of Mathematics. From your question, 'Ten less the quotient of a number and 3 is 6', we can write the algebraic equation. First, 'the quotient of a number and 3' is represented as x/3. Then, 'ten less' means we subtract 10 from the result. Lastly, 'is 6' means equals to 6. Therefore, the equation is: x/3 - 10 = 6.

To solve this equation, first of all, you should deal with the subtraction by adding 10 to both sides of the equation, which gives you x/3 = 16. Secondly, you then get rid of the fraction by multiplying both sides by 3, which yields x = 48. Hence 48 is the solution to your algebraic equation.

How to find the scale factor of a rectangle?

Answers

To find the scale factor, we divide one side by another that we know is correlated to that side (for example, if the sides are parallel). Since we can see that SR lines up with S'R' and RQ lines up with R'Q' (since it's in the same pyramid, they're parallel), they are similar. Finding the ratio, we get 6/15 or 4/10 or 2/5. That means that S'P' * 2/5=SP etc..
