Answer:

y = -4/5x + 14/5

Step-by-step explanation:

Point (6,-2) and (-4,6)

Slope = (6- - 2) / (-4-6) = 8 / -10 = - 4/5

(The slope is negative because La línea is going downhill. Uphill is positive)

You can also find the slope in the graph: rise/run.

y-intersect (any point)

Point (6, -2) (any point)

y-Intercept: -2 - (-4/5)(6) = -2 + 24/5 = 14/5

Answer:

The general equation of the line is 4x+5y−14=0. the y=mx+c = y = -4/5x + 14/5

Step-by-step explanation:

Step 1) Write down your coordinates = ( -4, 6 ) and ( 6, -2 ) Step 2) find the gradient y2-y1/ x2 - x1 = -2-6 / 6--4 = -8/ 10 = -0.8 = - 4/5 = slope However in the point slope formula we need to use 3 identities and as (0, 2.4) is present coordinate for y intercept = (2.4 - 6) / (0- -4 )= -3.6/4 = - 0.9 and (-2 -2.4)/ (6-0) = -4.4/ 6 = - 0.733 we know y it crosses at 2.8 however it recognises it is a descending value (the paramount difference at 2nd point = -0.9 -0.7333= -0.1667 and widest point 0.2667 - 0.1667 = -1 would be our ascending parallel multiplier

Answer:

10:1

Step-by-step explanation:

When you cross multiply the fractions together, you should get 30:3. When you simplify that, you get 10:1 as your answer.

The YMCA lap pool is a right rectangular prism 36.8\, \text{m}36.8m36, point, 8, start text, m, end text long by 20 \,\text{m}20

PilotLPTM [1.2K]

Volume is a three-dimensional scalar quantity. The depth of the YMCA lap pool is 2 meters.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given that the following details about the YMCA lap pool:

The volume of the pool = 1472m³
The length of the pool = 36.8m
The width of the pool = 20 m

Since the pool is in the space of a right rectangular prism, therefore, the volume of the prism will be the product of length, width and depth. Therefore, the volume of the pool can be written as,

The volume of the pool = Length × width × depth

1472m³ = 36.8m × 20 m × depth of the pool

Depth of the pool = (1472m³ ) / (36.8m × 20m)

= 2 meter

Hence, the depth of the YMCA lap pool is 2 meters.

Find XY if X(0, -7) and Y(-3, 2). d =

guapka [62]

9514 1404 393

Answer:

d = 3√10 ≈ 9.487

Step-by-step explanation:

The distance formula is appropriate.

d = √((x2 -x1)^2 +(y2 -y1)^2)

d = √((-3 -0)^2 +(2 -(-7))^2) = √(9 +81) = √90

d = 3√10

7x^2=9+x what are the values of x Will give medal and points

DENIUS [597]

7x² = 9 + x Subtract x from both sides
7x² - x = 9 Subtract 9 from both sides
7x² - x - 9 = 0 Use the Quadratic Formula

a = 7 , b = -1 , c = -9

x = $\frac{-b \pm \sqrt{b^2 - 4ac} }{2a}$ Plug in the a, b, and c values
x = $\frac{- (-1) \pm \sqrt{(-1)^2 - 4(7)(-9)} }{2(7)}$ Cancel out the double negative
x = $\frac{1 \pm \sqrt{(-1)^2 - 4(7)(-9)} }{2(7)}$ Square -1
x = $\frac{1 \pm \sqrt{1 - 4(7)(-9)} }{2(7)}$ Multiply 7 and -9
x = $\frac{1 \pm \sqrt{1 - 4(-63} }{2(7)}$ Multiply -4 and -63
x = $\frac{1 \pm \sqrt{1 + 252} }{2(7)}$ Multiply 2 and 7
x = $\frac{1 \pm \sqrt{1 + 252} }{14}$ Add 1 and 252
x = $\frac{1 \pm \sqrt{253} }{14}$ Split up the $\pm$
x = $\left \{ {{ \frac{1 + \sqrt{253} }{14} } \atop { \frac{1 - \sqrt{253} }{14} }} \right.$
The approximate square root of 253 is 15.905973.
x ≈ $\left \{ { \frac{1 + 15.905973}{14} } \atop { \frac{1 - 15.905973}{14} }} \right$ Add and subtract
x ≈ $\left \{ {{ \frac{16.905973}{14} } \atop { \frac{14.905973}{14} }} \right.$ Divide
x ≈ $\left \{ {{1.2075} \atop {1.0647}} \right.$ Round to the nearest hundredth
x ≈ $\left \{ {{1.21} \atop {1.06}} \right.$

This table represents a function plot the points to represent the function as a graph

yKpoI14uk [10]

Answer:

The graph in the attached figure N 2

Step-by-step explanation:

The complete question in the attached figure N 1

we have the ordered pairs

(-4,9),(-1,3),(0,1),(2,-3)

Using a graphing tool

Plot the given ordered pairs in the coordinate plane

Remember that

In a ordered pair (x,y), the first coordinate is the location of the point in the x-axis and the second coordinate is the location of the point in the y-axis

see the attached figure

The graph represent a line

Find the equation of the line
