Answer:

y = 2/3x + 5/3

Step-by-step explanation:

The slope of the line is ...

slope = (change in y)/(change in x) = (3-1)/(2-(-1)) = 2/3

Then the point-slope form of the desired line can be written ...

y = m(x -h) +k . . . . . slope m through point (h, k)

y = 2/3(x +1) +1 . . . . slope 2/3 through point (-1, 1)

y = 2/3x + 5/3 . . . . . . simplify to slope-intercept form

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for

swat32

Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25

Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450

Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420

The class earned more money in September and they earned $30 more than in October.

Question: F=d+e+t, solve for t.

Komok [63]

F = d + e + t Flip the sides to put t on the left
d + e + t = F Subtract d from both sides
e + t = F - d Subtract e from both sides
t = F - d - e

True or false: two points with the same x-coordinate are always on the same vertical line

Vesna [10]

True, you can even test it out yourself. If the domain (x) is the same then it will be a vertical line. Like if you graphed (1,2) (1,4), (1,6) it will be a vertical line on your graph. I hope this helps!
