This table gives a few (x,y) pairs of a line in the coordinate plane

blagie [28]

Answer:

The x-intercept of the line is the point (12,0)

Step-by-step explanation:

step 1

Find the slope of the lime

Take the points

(22,36) and (32,72)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{72-36}{32-22}$

$m=\frac{36}{10}$

$m=3.6$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=3.6$

$point (22,36)$

substitute

$y-36=3.6(x-22)$

step 3

Find the x-intercept

we know that

The x-intercept of a line is the value of x when the value of y is equal to zero

For y=0

substitute in the equation and solve for x

$0-36=3.6(x-22)$

$0-36=3.6x-79.2$

$3.6x=79.2-36$

$3.6x=43.2$

$x=12$

therefore

The x-intercept of the line is the point (12,0)

Can someone help me in 1

oee [108]

Answer:

1,260 sq ft

Step-by-step explanation:

FORMULA TO FIND AREA OF A RECTANGLE: L*W, l=length, w=width

we can divide the figure into three other rectangles

rectangle one) length=20 width=10

so 20*10=200

rectangle 2) length=45, width=20

so 45*20=900

rectangle 3) length=20 width=8

so 20*8=160

now we add up the areas of the 3 rectangles to find the area of our figure

200+900+160=1,260 sq ft

hope this helps!

What is the vertex of f(x)=(x+1)^2-6

RoseWind [281]

(-1, -6) is the vertex of that equation. use the number in the brackets and change the signs for the x-value. use the last number outside of the brackets for the y-value

A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 666 centimeters

faltersainse [42]

Answer:

y = mx + b

slope(m) = 6

(20,220)....x = 20 and y = 220

now sub and find b, the y int

220 = 6(20) + b

220 = 120 + b

220 - 120 = b

100 = b

so ur equation is : y = 6x + 100

to graph :

y = 6x + 100.....u have a slope of 6....u have a y int of 100 or (0,100)...

I would say plot (0,100) and since ur slope is 6, go up 6 and to the right 1...but that is not to helpful because ur graph is not in intervals of 1.

So we will find some points on ur line.

y = 6x + 100....when x = 5

y = 6(5) + 100

y = 30 + 100

y = 130....so another point on ur line is (5,130)

y = 6x + 100...subbing in 10 for x

y = 6(10) + 100

y = 60 + 100

y = 160....another point is (10,160)

keep finding points this way...here are some more...

(15,190) , (20,220), (25,250)
