If the slope is -3, the answer is D

the required equation of the line is y = -3x + 8. option D is correct.

Given that,

To determine an equation of the line through (3, -1) and (−2, 14).

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx, where x is in degrees.

What is simplification?

The process in computation to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

Slopes of the line can be given as,

m = [y₂ - y₁ ] / [x₂ - x₁]

for points, (3, -1) and (−2, 14)

m = 14 + 1 / -2 - 3

m = -15 / 5

m = -3

So, equation D contains the slope -3.

Thus, the required equation of the line is y = -3x + 8. option D is correct.

Rewrite without absolute value for the given condition: y=|10-x|, if x<10

Answers

Answer:

The answer is 10-x

Step-by-step explanation:

The absolute value of the equation is given by y = 10 - x

What is Modulus Function?

Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.

It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:

If x is positive, then f(x) = x

If x = 0, then f(x) = 0

If x < 0, then f(x) = -x

Given data ,

Let the modulus function be represented as A

Now , the value of A is

y = | 10 - x | be equation (1)

Now , the absolute value of the function when x is less than 10 is

when x < 10

y = | 10 - x |

y = 10 - x

Hence , the value of absolute function is y = 10 - x

Answer: D) 198 square meters

======================================================

Explanation:

Extend the side that's 9.5 meters long out to the left so that you form a trapezoid on top and a rectangle underneath. The side we extended is now 5+9.5 = 14.5 meters long.

Let

A = area of the trapezoid up topB = area of the rectangle underneath

The goal is to find A+B

The trapezoid has the parallel sides of 14.5 and 10 meters. The height of the trapezoid is 28-20 = 8 meters. So we can say

Area of trapezoid = height*(base1+base2)/2

A = h*(b1+b2)/2

A = 8*(14.5+10)/2

A = 98

The rectangle has area of B = length*width = 5*20 = 100 square meters

Therefore,

total area = A+B = 98+100 = 198 square meters.

What is the y-intercept?
What is the x-intercept?
What is the slope of the line?
Find an equation for this line.

Answers

Answer:

Step-by-step explanation:

The "y intercept" is the point at which the graph intercepts the y-axis. In this case that point is (0, 20).

The "x intercept" is the point at which the graph intercepts the x-axis. In this case that point is (5, 0).

The slope of the line is m = rise / run. Here the "rise" is actually a drop from y = 20 to y = 0, so "rise" = -20. The "run" is the increase from x = 0 to x = 5, which is 5. Thus, m = the slope = -20/5 = -4. The slope is m = -4.

Given that we know the slope, m, of this line (m = -4) and two points on the line (use (0, 20) ), we can write the equation of the line immediately in point-slope form y - k = m(x - h), which in this particular case is

y - 20 = m(x - 0), or

y - 20 = -4x

Alternatively, we could put this into standard form: 4x + y = 20, or into

slope-intercept form: y = -4x + 20

In a garden, 2/3 of the flowers are roses. Of the roses in the garden, 5/12 are yellow and the rest are red. What fraction of the flowers are red roses?

Answers

7/18 of the flowers are red roses

because 5/12 are yellow, the rest would be red. so 7/12. but total roses are only 2/3 of the whole garden.

tip: when you see "of" in a fraction problem, it means you can multiply them.

so, 7/12 OF 2/3 is just (7/12) * (2/3).
multiplying straight across and simplifying will get you to 7/18!
