The equation of line m is 3x−5y=−4.

1 answer:

8 0

I line that is perpendicular is a line with reversed slopes like 2/1 is perpendicular to -1/2. So find the slope by getting the y by itself and reverse it. Remember to switch the signs too! P.S. if you don't know how to get the y by itself just take and subtract 3x from -5y and -4 then divide by 5. Hope I helped!

Work out the lengh of RS <br> gue your answer to 3 significant figures

atroni [7]

Answer:

RS ≈ 5.83 units

Step-by-step explanation:

Calculate RS using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = R(- 3, 1) and (x₂, y₂ ) = S(2, 4)

RS = $\sqrt{(2+3)^2+(4-1)^2}$

= $\sqrt{5^2+3^2}$

= $\sqrt{25+9}$

= $\sqrt{34}$ ≈ 5.83 ( to 3 significant figures )

What equation models the data in the table if d = number of days and c = cost?

dedylja [7]

Answer:

c=3d

Step-by-step explanation:

What equation models the data in the table if d = number of days and c = cost? Days Cost 2 6 3 9 5 15 6 18

Answer: An equation is a statement used to show the relationship between variables and shows the equality between two expressions. We want to find the relationship between the number of days and the cost.

Given that:

Days Cost

2 6

3 9

5 15

6 18

Lets take the ratio of days to cost using the first row:

$\frac{d}{c}=\frac{2}{6}\\ \frac{d}{c}=\frac{1}{3}\\c=3d$

The relationship c = 3d is true for all values of days and cost

How many triangles would be needed to cover 7/3 trapezoid 7/3 ×3=7 Am I right I think it 21 doe.

jarptica [38.1K]

Answer:

5 or 6 (or 2 or 7)

Step-by-step explanation:

Any quadrilateral can be covered by 2 triangles, so the integer number in 7/3 = 2 1/3 quadrilaerals will require 2×2 = 4 triangles.

The meaning of (1/3) trapezoid determines the number of additional triangles required. If 1/3 trapezoid is a triangle, only one is needed. If 1/3 trapezoid is a quadrilateral, then 2 triangles are needed.

_____

If the 7/3 trapezoids are butted against each other so they make a larger quadrilateral figure, then only 2 triangles are needed.

_____

If each trapezoid is constructed from 3 equilateral triangles, and you want to know the total number of those equilateral triangles in 7/3 such figures, it will be 3 × 7/3 = 7.

The answer depends on problem details not provided here.
