Answer:
The required point is P(-7,) where, x-coordinate twice the y-coordinate on line 2x - 6y = 7
Step-by-step explanation:
Given equation of line is 2x-6y=7
To find point on graph whose x-coordinate twice the y-coordinate:
Let y be y-coordinate of point
Hence, x-coordinate of point will be 2y
The required point is P(2y,y) on equation of line 2x-6y=7
Now,
2x-6y=7
2(2y)-6y=7
-2y=7
y=
Thus,
The required point is P(-7,)
Note: Figure show equation of line red line and point P as blue dot.
Answer:
let length be b+5 and breadth be b
given,
perimeter of rectangle=150
or, 2(l+b) =150
or, 2(b+5+b)=150
or, 2b+5=150/2
or, 2b+5=75
or, 2b=70
therefore, b=35m
l=b+5
=35+5
=40m
Answer: Limit does not exist, therefore, i believe it's DNE.
**I might be incorrect
Step-by-step explanation:
Answer:
10 and 2/7
Step-by-step explanation:
7/6 = 1 1/6
12 /( 1 1/6)
Convert first the cost of $98 /yd³ by the conversion factor that 1 yd³ = 27 ft³.
($98 /yd³) (1 yd³ / 27 ft³) = $ 3 17/27/ft³
Let x be the width, the volume of the rectangular portion of the driveway is,
V = (8 ft) (1/3 ft) x = 8x/3 ft³
Using the given total cost of the protion,
C = $58.07 = (8x/3 ft³)(<span>$ 3 17/27/ft³)
x = 5.99957 ft
Thus, the answer is d. 6 feet.</span>
