3x + 7y = 7
7y = -3x + 7
y = -3/7x + 1
slope = -3/7 (so ur line is decreasing)
y int.....line crosses y axis at (0,1)
x int...line crosses x axis at (7/3,0)....for graphing purposes, 7/3 = 2 1/3
so start at (0,1).....go down 3 and to the right 7, and u will notice that ur line will cross the x axis at (7/3,0)
Answer:
The answer is B 300 sq. ft.
Step-by-step explanation:
If you multiply 15 by 2 you were to get 30 but since it is 15 multiplied by 20 instead its like adding a 0 at the end of the number so we change 30 to 300.
Hope this helps :)
Answer:
Step-by-step explanation:
First term = a =4
Common difference = d = 2nd term - first term
d = 8 - 4 = 4
Last term = l = 400
First we have to fin the number of terms 'n'
l = a + (n-1)d
4 + (n-1)*4 = 400
4 + 4n- 4 = 400
4n = 400 {Divide both sides by 4}
n = 400/4
n = 100
Answer:
Step-by-step explanation:
With a slope of 1 and a y intercept of -3
y = 1x - 3
y = 1(-2) - 3
y = -5
(-2, -5)
Answer:
Step-by-step explanation:
Complement = 90 - Angle
Complement = 90 - y
Complement = 90 - (8x - 20)
Complement = 90 - 8x + 20
Complement = -8x + 110
