√81=9
21÷9=2.3333(recurring)
2.33333×15=x
X=34.999
or X=35 to 1 d.p
Answer:
Step-by-step explanation:
let a=Ann's amt., b=Betty's amt.
a=2b+9
b+2b+9=60
3b+9-9=60-9
3b=51
b=$17
a=34+9=$43
Both ........................
Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (1, 9) , thus
y - 9 = 2(x - 1) → C

<u>Question:</u></h3>
Find the equation of line perpendicular to x = 1 and passing through (7, 11)
<h3><u>Answer:</u></h3>
The equation of line Perpendicular to x = 1 and passing through (7, 11) is y = 11
<h3><u>
Solution:</u></h3>
Given that line is perpendicular to x = 1 and passing through (7, 11)
We have to find the equation of line
The equation of the line in standard form is x = 1
This is a vertical line, so the perpendicular line will be a horizontal line of the form y = b
Since we are given that the line should pass through the point (7, 11) then the equation of the line is y = 11
