You would need to see the rest of the equation to plug in 7 for x. Treat it as y=equation and replace any x with 7.
Answer:
It's a simultaneous equation because it as two solution
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that L is a line parametrized by

The plane perpendicular to the line will have normal as this line and hence direction ratios of normal would be coefficient of t in x,y,z
i.e. (2,3,-1)
So equation of the plane would be of the form

Use the fact that the plane passes through (2,0,-1) and hence this point will satisfy this equation.

So equation is

b) Substitute general point of L in the plane to find the intersecting point

i.e. same point given.
25% of 180 is 45.
You do the equation 25%*180 which equals to 45. The word of means multiply and the word is means equal
$500 was earned over 3 years
so, to find one year
500 ÷ 3 = $166.67
Interest for one year is $166.67
Interest rate for one year is 8%
8% = 166.67
1% = $20.83
100% = $2083.33
Principal amount is $2083.33
